Using glass cloth tape to stick silicone rubber, common application scenarios include using it as an auxiliary material in FPC (flexible printed circuit board) lamination process, or fixing and protecting silicone components in high temperature environments.Here is a detailed operation guide, hoping to be helpful to you:✍️ preparation in advanceSurface cleaning: This is the most crucial first step. Please use a dry cloth, brush, or dipped in alcohol, acetone, or other cleaning agents to thoroughly remove dust, oil, and impurities from the silicone rubber and the surface of the object being pasted, to ensure a firm adhesion and avoid moisture affecting electronic products during cleaning.Material cutting: Cut the glass cloth tape and silicone rubber into suitable shapes and sizes according to actual needs.📝 Paste core stepsPositioning and pasting: Due to the strong initial adhesion of the glass cloth tape, it is difficult to adjust once it is pasted, so it is necessary to accurately paste it all at once after determining the position. Use the "direct bonding method" to attach the tape to the silicone rubber, and repeatedly press the tape with force to fully utilize the adhesive layer, ensuring no bubbles and tight pression and static placement: In specific processes such as FPC compression, hot pressing is usually required after bonding. Accurate control of parameters such as pressure, temperature, and time is required. After completing the operation, it is best to let it stand for 24 hours to achieve the best bonding strength of the tape, and try to avoid applying external forces to the bonding area during this period.Surface protection and inspection: After pasting, if there is glue overflow, it can be carefully cleaned with a blade. The final step is to carefully check whether the adhesive surface is smooth and free of impurities such as bubbles and particles, to ensure the quality of the bonding.Here are several typical application scenarios that can be referred to:💡 Application scenario referenceFPC hot pressing process: The glass cloth tape is attached to the silicone rubber, which plays a role in buffering, preventing displacement, blocking adhesive overflow, and filling uneven lines during pressing.High temperature equipment fixation: Utilizing its wide temperature resistance range of -40 ℃ to 260 ℃, it is used for sealing, sandblasting protection, coil binding, etc. of high-temperature pipelines.Adhesive of silicone related products: Some special tapes (such as Japan's IPROS G-301 and Desha's 61526) can directly adhere silicone or perform heterogeneous bonding between silicone and other materials.Temporary protection and fixation: used to shield and protect specific parts of precision electronics or household appliances during painting, welding, and other processes, with no residual adhesive after removalFlexible high-temperature epoxy adhesive film for copper-clad laminates
The specialized flexible high-temperature epoxy adhesive film for copper-clad laminates is a key basic material, mainly used to manufacture flexible printed circuit boards (FPCs). It is essentially a conductive adhesive film that has been specially modified to have both flexibility and high temperature resistance.Core technology: Using "toughening" to solve the problem of "brittleness"After curing, pure epoxy resin becomes brittle and has poor fatigue resistance, so it needs to be modified by physical or chemical methods for "toughening". This is the core technology that gives it flexibility. Common modification methods include:Rubber toughening: This is the most common method. By adding toughening agents such as carboxyl terminated nitrile rubber (CTBN) to epoxy resin, its toughness and peel strength can be significantly improved. Research has shown that when 30 parts of CTBN are added to epoxy adhesive, the impact strength of the modified film can be increased by nearly 149.7%.Chemical modification: Introducing chemical groups such as bismaleimide copolymer (BMI) can effectively increase the flexibility of the adhesive film without sacrificing heat resistance.Key performance indicatorsTo evaluate the performance of this adhesive film, the following three indicators should be considered:High peel strength: ensures that the copper foil will not peel off during subsequent processing (such as PCB "subtractive process" etching) of the copper-clad laminate. It is usually required that its peel strength be greater than 1 kgf/cm, but through modification, the peel strength of the adhesive film can reach up to 2.67 N/mm.Flexibility: This is a characteristic brought about by the aforementioned toughening modification, ensuring that it can adapt to various bending scenarios.High temperature resistance: In the lead-free reflow soldering process at 288-320 ℃, there should be no blistering or delamination of the adhesive film to ensure the reliability of the FPC.Application scenarios: From consumer electronics to specialty industriesThe core application of this adhesive film is the production of flexible copper-clad laminates (FCCL). According to different preparation processes, it can be further divided into:The 3-layer FCCL method, which uses adhesive to bond polyimide (PI) film and copper foil, is currently the most widely used process.2-Layer FCCL: does not rely on adhesives, requires higher technology and cost, but also has superior performance, commonly used in high-end products. Some technologically advanced enterprises already have the ability to mass produce such materials.Specific application areas include:Specific application field descriptionHigh density and high reliability flexible circuit boards for consumer electronics products such as smartphones, tablets, and digital cameras.Electronic components that require rigorous environmental testing in special industrial aerospace, military, and high-end medical equipment.Industry chain related enterprisesApplication and R&D: Domestic enterprises such as Shengyi Technology are important manufacturers of flexible copper-clad laminates.

This method is widely used in scenarios such as high gloss LOGO processing on mobile phone metal frames and aluminum alloy product surfaces.Working principle: A hard protective layer is formed on the surface of the substrate through screen printing, exposure development, or spray coating processes. This layer of ink can withstand the impact of sandblasting, protect the areas that need to be preserved, and achieve precise etching of logos or patterns.Core advantage: High precision, photosensitive development ink can achieve a resolution of 20 μ m, fully meeting the production needs of fine logos. The curing time of UV curable ink is only 5 seconds, suitable for large-scale production.Removal method: After sandblasting, it can be soaked in dilute alkali solution (such as 5% NaOH solution) or mechanically peeled off without leaving any residue.Key parameters: Impact resistance of approximately 0.2-0.5MPa; The ink film layer has high elasticity and sand resistance.Supplier reference: Shenzhen Wanjia Yuan Fine Chemical Technology Co., Ltd. is one of the suppliers of this type of ink.🛡️ Option 2: Thermal anti sticking protective film - convenient overall protectionIf considering the use of solid film, it is mainly used for masking and temporary fixation before sandblasting, rather than directly as logo ink. For example, sticking a logo masking film on aluminum alloy products before sandblasting is a typical application.Working principle: Maintain viscosity at room temperature, used to protect or fix workpieces. After processing, by heating to a specific temperature (such as 100 ° C to 180 ° C), its viscosity will sharply decrease (foaming peeling), making it easy to remove.Core advantage: No residual glue is its most prominent advantage, and it will not contaminate the surface of the protected object after heating and peeling. Easy to use, can be peeled off after processing.Key parameters: The conventional adhesion force is relatively high at room temperature and decreases to about 0.02N/20mm after foaming; The peeling time usually ranges from 10 seconds to 5 minutes.In addition to thermal anti adhesive protective films, traditional sandblasting protective films (such as PVC materials) used for sandblasting protection are also widely used, especially for large-area protection.🔩 Key Process and Structural AnalysisComparison of core processes:Anti sandblasting ink process: cleaning → silk screen printing/spraying ink → curing (UV or hot air) → sandblasting → peeling.Protective film process: cleaning → film application (cold/hot pressing) → sandblasting → heating peeling.The structure of sandblasting protective film is usually a three-layer composite structure, including the surface layer, middle layer, and adhesive layer. For example, a common structure is: PVC film+gelatin (water-based adhesive)+release paperMLCC upper/lower tape coated with silver tape
In the production of MLCC (Multi Layer Ceramic Capacitors), the "upper/lower tape" and "silver dipping tape" you asked about are two completely different specialized tapes that play important roles in packaging, transportation, and electrode manufacturing, respectively.📦 Cover/Base TapeThis type of tape is mainly used for packaging and transportation of electronic components. They are used in conjunction with paper carriers to securely seal small components such as MLCC in the grooves of the carrier for accurate picking on automated surface mount machines.Core requirement: To prevent tiny MLCC from being electrostatically broken down, this type of tape usually needs to undergo anti-static treatment. At the same time, they also need to have stable peeling force (pulling force) to ensure that they can be smoothly peeled off on the automatic mounting machine without leaving irregular tear marks.Main suppliers: Major players in the industry include Japan's Mattei Group, Jiemei Technology, and some professional manufacturers such as Taicang Qunte Electrical Materials.🎨 Silver Termination TapeThis type of tape is used in the "sealing" process of MLCC manufacturing to protect the ceramic body parts that do not require sizing. Due to the need to be exposed to high temperatures, it has high requirements for heat resistance.Working principle: When silver paste (or copper paste) is applied to the end of MLCC to form an external electrode, this tape tightly wraps around the rest of the capacitor, providing shielding and protection. Subsequently, the components with adhesive tape will enter a high-temperature oven or sintering furnace for processing.Core technical requirements:High temperature resistance: This is the most critical characteristic. After high-temperature treatment at 200 ° C to 260 ° C, the performance of the tape must remain stable and cannot deform or melt.No residual adhesive: When peeled off after the process is completed, it must be 100% residue free. Any residual adhesive will affect the performance or appearance of MLCC.Flexible and snug: The tape needs to be able to tightly adhere to the tiny surface of MLCC, providing reliable shielding for subsequent electroplating, sintering, and other processes.Main suppliers: The main suppliers in the market include Shenzhen Yizhong Technology Co., Ltd., Dongguan Xinpengda Adhesive Products Co., Ltd., Haojia Enterprise Co., Ltd., Shenzhen Youtu Technology, etc.⚙️ New choice in technology: thermal foaming tapeIn the "silver dipping" process, in addition to traditional silver dipping tape, a more advanced thermal foaming tape is becoming popular.Traditional silver coated adhesive tape needs to be manually or mechanically removed after protection, while thermal foam tape utilizes its own characteristics to rapidly expand in volume at specific high temperatures (about 190-210 ° C), thereby automatically and completely eliminating the stickiness and achieving automatic unloading of components. This characteristic makes it more suitable for high-precision automated production and can effectively avoid the physical damage that traditional tape may cause to fragile ceramic bodies or electrodes when torn off, especially when dealing with small-sized MLCCsWater soluble double-sided tape
Water soluble double-sided tape, also known as "water soluble" or "re wettable" double-sided tape, is a special type of tape that can be rendered adhesive and achieve environmentally friendly separation by water.It is composed of water-soluble substrates (such as specialty paper, non-woven fabric) and water-soluble adhesives (usually modified acrylic acid), which can decompose or dissolve when exposed to water. Its core advantage lies in the ability to avoid non water soluble materials from polluting the recycling system, ensuring resource reuse.Application areas: from industry to daily lifeThe application of water-soluble double-sided tape is mainly divided into two categories: industrial grade and civilian grade.⚙️ Industrial sector (mainly paper and printing industry)Paper Flyover/Automatic Splicing: Used in high-speed production of roll paper to connect new and old paper rolls, the tape can be completely dissolved in the subsequent pulp making process without affecting pulp quality and equipment.Rolling and sealing: Fix the paper on the core or stick the tail of the roll to ensure no residue and no impact on recycling.🧵 In the civilian/handmade field (mainly Japanese brands such as Clover Cola)Temporary fixed fabric: used to temporarily fix fabrics, lace, zippers, etc. during *ing. After *ing, they can be removed by soaking in water to avoid thread removal or fabric damage.Making a water-soluble embroidery substrate: As a base for embroidery, it dissolves in water after completion, leaving only exquisite embroidery pieces.Other applications: It can also be used for medical sealing, environmentally friendly packaging, special anti-counterfeiting labels, etc.Mainstream brands and productsInternationally renowned tape brands all offer water-soluble product lines, mainly serving the industrial market.Tesa: Provides a comprehensive product line, such as the CaRes series and EasySplice series, some of which use patented calcium resistant technology to adapt to hard water environments. In the series, there are pure adhesive films without substrates (such as tesa) available ® 51916), as well as paper substrates (such as tesa) ® 51914) and other options.3M: Its water-soluble tape (such as the R996 series) adopts a double-layer design, and the tape itself can be directly peeled off from the lining for easy operation.Nitto (Nitto): Model number 509A, made of non-woven fabric substrate, suitable for automatic splicing in papermaking.Clover: mainly targeting the handicraft market, the product is compact and specifically designed for temporary fixation of fabrics.Other: There are also Orafol (such as ORAFIX) on the market ® 12885), Sharktope, and numerous domestic brands to choose from.Key technical parametersWhen purchasing, please pay special attention to the following indicators:Solubility: Pay attention to its repeatability, which means whether it can be fully decomposed in water without producing clumps.Adhesive force: Water soluble tape usually has high initial adhesive force to meet the needs of temporary fixation.Temperature resistance: Different products have significant differences in temperature resistance. 3M R996 tape can withstand high temperatures up to 204 ° C for a short period of time, while ordinary products may only be used at room temperature.PH adaptability: Some products (such as tesa) claim to dissolve well within the pH range of 3 to 9.Selection and usage precautionsClear application scenarios: Industrial applications should choose models with high adhesion and rapid dissolution; For manual use, attention should be paid to whether it is suitable for specific fabrics and whether there is no residue after *ing.Pay attention to environmental certification: Check whether the product meets FDA (Food and Drug Administration) food contact level standards or TAPPI (Pulp and Paper Industry Technical Association) re pulp standards to ensure environmental safety.Storage conditions: It must be stored in a cool and dry place to avoid the performance degradation of the tape caused by high temperature and humidity.In summary, the core advantage of water-soluble double-sided tape lies in its ability to separate from water, mainly serving the industrial sector that pursues environmental protection and efficient production, and playing an important role in fine handicrafts.Flame retardant aluminum foil fiberglass cloth tape

LED potting tape is a high-temperature masking tape specifically designed for the manufacturing process of LEDs (light-emitting diodes). Its core function is to seal and protect specific areas during the epoxy resin encapsulation and high-temperature curing process of LED.This type of tape typically has the following key characteristics:High temperature resistance: This is its core performance to ensure stable performance during the high-temperature curing process from 150 ° C to 260 ° C.Clean peeling: It can be easily peeled off after use without leaving any residue on the surface of the object being pasted, which is a key indicator for evaluating its quality.Chemical resistance: able to resist the erosion of chemicals such as epoxy resin during the sealing process.Precise fitting: The texture is soft and can be tightly attached to the surface of the LED module, effectively preventing leakage of the sealing glue (i.e. "glue overflow").Effect control: The surface of the tape is divided into two types: matte and glossy.

In glass thinning and etching processes, a special protective film is required to protect non processed areas. UV reducing film (also known as UV film) is designed for this purpose, and PO (polyolefin) is one of the high-performance substrates.It is like an "intelligent shield" that firmly adheres to provide protection during processing. After processing, it can be easily and completely peeled off by UV light irradiation without leaving any residue.⚙️ Core feature: How does it work?The excellent performance of UV reducing film in glass etching process is attributed to its unique design:UV debonding and non-destructive peeling: this is its core function. Before exposure to ultraviolet (UV) light, the tape has high adhesion (such as initial adhesion of PO material up to 1300 gf/25mm), which can firmly adhere to the glass surface and prevent etching solution from penetrating. After completing the protection task, the adhesion will instantly decrease significantly through UV light irradiation, reaching a nearly non stick state (such as PO material dropping to 25 gf/25mm after debonding), making it easy and non-destructive to peel off, effectively avoiding the risk of glass substrate cracking due to uneven tearing force.Excellent acid and alkali corrosion resistance: Highly corrosive solutions such as hydrofluoric acid (HF) and hydrochloric acid (HCL) are often used in etching processes. This type of protective film can effectively resist the erosion of these chemicals, preventing them from warping, peeling, or seeping during complex acid washing processes.No residual glue, high cleanliness: Excellent UV debonding process and colloidal formula ensure that after the film material is peeled off, the glass surface can maintain its original cleanliness without adhesive residue. This is the key to ensuring the quality of subsequent processes and product yield, and it is also an important reason why PO protective films are highly favored in high-end applications.🛡️ PO substrate vs. PET substrate: how to choose?The performance of UV thinning film is closely related to the substrate (i.e. the main material of the film), and the common ones are PO and PET (polyester film), which have significant performance emphasis in glass thinning etching process. You can choose according to your specific application scenario:Characteristics PO (Polyolefin) PET (Polyester)Base material characteristics: The material is soft, with excellent ductility and cushioning properties. The material is relatively hard, with good stiffness, better temperature resistance, and dimensional stabilityThe key process is manifested in glass thinning/etching, which can provide excellent adhesion and buffering protection; Excellent acid resistance performance, some products can be sprayed under mixed acid for more than 200 minutes without acid leakage or detachment. They perform well in cutting, grinding and other processes that require high fixation force, with good processing performance and easy punching and cuttingThe application scenarios are mainly recommended for complex chemical etching, glass thinning, and strengthening processes. Its excellent acid resistance and flexibility make it the preferred choice for single-sided thinning of mobile phone glass covers, OLED/TFT panels, and other fields, mainly used for high-strength cutting, grinding, and other processes. It is also suitable for glass thinning protection, but in terms of acid resistance, conventional PET film may not be as good as PO filmViscosity change (gf/25mm) approximately 1300-1600 before UV irradiationAbout 25-30 after UV irradiation and about 1100-2200 before UV irradiationAbout 6-7 after UV irradiationReference temperature resistance: Long term temperature resistance of about 80 ℃Short term temperature resistance can reach 90-120 ℃, and long-term temperature resistance is about 80 ℃Short term temperature resistance of about 120 ℃Adhesive force (gf/25mm) refers to the adhesive force on a width of 25mm, with higher values indicating stronger initial adhesion.🔍 Application process: from attachment to peelingUnderstanding how it operates in actual production helps to better understand its value:Attachment: Before etching, apply the UV reducing film evenly to the glass surface that needs to be protected (such as the display area), and ensure that the two are tightly adhered without bubbles.Etching: Chemical etching is performed, during which the protective film, with its high viscosity and acid resistance, effectively blocks the etching solution from corroding non target areas.UV irradiation: After etching is completed, use UV curing equipment to irradiate the protective film. The photoinitiator in the adhesive layer reacts rapidly under UV light irradiation, causing cross-linking or changes in the molecular structure of the adhesive layer, resulting in a significant decrease in viscosity.Peel off: After UV irradiation, the protective film with extremely low viscosity can be easily and completely peeled off from the glass surface without leaving any residue, completing the protective missionPlasma thermal spraying masking tape
Plasma thermal spraying (including plasma spraying, supersonic flame spraying HVOF, flame spraying, etc.) is a high-temperature and high-speed process that requires much stricter requirements for masking tape than ordinary PCB furnace protection. The core feature of this type of tape is that it is made of glass fiber cloth as the substrate, coated with high-temperature resistant silicone adhesive, and some high-end products also have a composite aluminum foil layer to enhance heat radiation resistance.The following are mainstream tape solutions for this special process:🔥 Comparison of core products of plasma thermal spraying masking tapeTape type/model Core structure and characteristics Temperature resistance Main application scenarios Typical appearanceSilicone rubber/fiberglass cloth composite tape (universal type) is based on high-strength fiberglass cloth coated with high-temperature resistant silicone.
