Die-cutting and processing of double-sided adhesive tape

Die cutting is the process of cutting double-sided tape (or other roll like materials) into specific shapes and sizes through precision molds according to design requirements. This is a crucial post-processing step in industries such as electronics, automotive, medical, and home appliances.Below is a detailed analysis of the die-cutting process for double-sided tape:1、 Core processing flow (standard steps)Material preparation:Substrate selection: Double sided tape itself, commonly such as PET double-sided tape, foam double-sided tape, non substrate double-sided tape (film), VHB tape, etc.Release paper/film: Depending on the process requirements, it may involve single-sided or double-sided release materials.Auxiliary materials: Sometimes it is necessary to composite other materials, such as protective film, conductive cloth, insulating film, etc.Design knife mold:Types of knife molds: Commonly used are carving molds (for integral steel carving, with the highest precision), etching molds (for chemical etching, used for thin materials and complex shapes), and hardware molds (for large batches and simple shapes).Design points: Consider tape thickness, adhesion, and waste disposal methods. The blade angle and height need to be accurately calculated to ensure that the adhesive layer is cut through without damaging the backing paper or only partially cutting.Machine die-cutting:Place the raw material roll on the unwinding reel and pass it through the die-cutting machine.Driven by precision guide rails, the material passes through the die area and is cut into shape under stamping action.This is the most crucial step, which requires extremely high stability of the machine (concentricity, pressure control).Waste disposal:Frame waste removal: Remove waste edges outside the product's appearance.Inner hole waste removal: Remove unwanted adhesive material inside the product (such as the adhesive in the middle circular hole). This step is quite difficult and often requires auxiliary devices such as ejector pins and blowing air.Whether the waste disposal is clean and efficient directly determines the production efficiency and yield rate.Roll up or SMT:Roll up: Roll the die cut product back into a roll shape, usually kept on release paper.SMT: A single piece of die cut product is attached to another release film to form a single product, which is convenient for manual or automated mounting.Quality inspection and packaging:Check the size, shape, burrs, glue overflow, dirt, etc.Conducted in a clean room to prevent dust from affecting adhesive properties.Pack according to requirements for anti-static and vacuum protection.2、 Key Technologies and DifficultiesAnti overflow glue treatment:Double sided adhesive is prone to overflow due to pressure and heat, which can contaminate molds and products.Solution: Use anti overflow adhesive knife mold (special coating or structure), optimize pressure and speed, control ambient temperature, and select appropriate tape.Cutting depth control:Half cut: Only cut through the adhesive tape layer, without cutting the release paper at the bottom layer. This is the most common process with high technical plete cutting: Cut through all layers at once.Inaccurate depth control can lead to difficulty in peeling off the product or difficult waste disposal.Small size and complex shape:With the miniaturization of electronic products, the particle size may be less than 1mm and the shape may be complex (such as irregular shapes, multiple islands).Propose ultimate challenges to the precision of the cutting die, material tension control, and waste disposal technology.Multi layer composite material die-cutting:Die cutting multiple composite materials (such as tape, conductive foam, and protective film) at once, with different physical properties of each layer of material, increases the difficulty significantly.3、 Application scenario examplesMobile phones/tablets: battery mounting frame, screen pad with high foam, camera dust gasket, internal component shielding adhesive, etc.Automotive electronics: sensor fixing gasket, interior panel adhesive, wire harness fixing dical devices: disposable electrode pads, medical dressings backing adhesive, equipment sealing gaskets.Home appliances: nameplate adhesive, sealing strip, shock-absorbing gasket.4、 How to choose a suitable die-cutting supplierTechnical ability: Can you handle the complexity of your product (size, shape, material combination).Equipment level: high-precision rotary die-cutting machine or flat blade die-cutting machine? Do you have automated testing equipment?Clean environment: Whether there is a corresponding level of dust-free workshop.Quality system: Whether there is a sound ISO quality control system and whether the measuring tools are precise.Sample capability: Sampling speed and sample quality are the most direct ways to evaluate its technology.Cost and delivery time: Comprehensive evaluation while ensuring quality.summaryDie cutting double-sided tape may seem simple, but it is actually a comprehensive technology that integrates materials science, precision machinery, mold engineering, and process experience. Its value lies in transforming ordinary coils into key components that can meet specific design functions, high precision, and high reliability.If you have specific products that require die-cutting, the best way is to provide drawings or samples to a professional die-cutting factory for consultation and sampling. They can provide the most suitable process plan and quotation based on your specific needs (materials, dimensions, uses, quantities).

防静电PI胶带

We specialize in anti-static PI tape. This is a high-end specialty tape that combines high temperature resistance, high insulation, and electrostatic discharge/shielding functions. It is a key material for protecting sensitive electronic components and ensuring production yield.The core overview is that anti-static PI tape is made by coating an anti-static adhesive on a high-performance polyimide film substrate, or by surface treating the substrate (such as coating with an anti-static coating).PI substrate: It is a "gold standard" high-temperature resistant insulation material, renowned for its excellent heat resistance, mechanical strength, and chemical stability.Anti-static function: Designed to address the issue of electrostatic discharge in electronic manufacturing, it prevents damage to integrated circuits, optoelectronic components, etc. by safely discharging or shielding electrical charges.Key Features and Advantages: Ultimate High Temperature Resistance:The PI substrate itself can withstand temperatures ranging from -269°C to 260°C for extended periods, and can endure temperatures exceeding 400°C for short periods. This enables PI tape to easily handle demanding processes such as reflow soldering, wave soldering, chip packaging, and high-temperature baking.Excellent electrical performance:In addition to being an excellent insulator (high dielectric strength), its anti-static version, through technical means, maintains its surface resistivity within a specific anti-static/static dissipation range (typically 10⁴ ~ 10¹¹ Ω/sq), ensuring that it neither accumulates charges due to insulation nor causes short circuits due to conductivity.Excellent mechanical and chemical properties:High strength, tear resistance, puncture resistance, and excellent dimensional stability.It is resistant to most organic solvents, acids, alkalis, and oils, and maintains stable performance even in harsh environments.Diverse ways to achieve functions:Surface anti-static type: An anti-static layer is only applied to the surface of the PI film, while the substrate itself remains insulating. It is primarily used for surface protection and isolation shielding.Overall anti-static type: The PI film itself or the adhesive has undergone special treatment, endowing the entire tape with anti-static properties. After bonding, it can form an electrostatic discharge channel.Key performance parameter: substrate: polyimide filmColor: Typically amber (tea color), but also available in black or customized colors.Thickness: Commonly seen thicknesses include 0.025mm, 0.05mm, 0.075mm, 0.1mm, etc., which are very thin and lightweight.Long-term temperature resistance: -269°C ~ 260°C (due to the inherent properties of the substrate, the temperature resistance of the adhesive is typically in the range of 180-200°C).Surface resistivity: This is the core indicator of anti-static performance.Electrostatic dissipation range: 10⁴ ~ 10¹¹ Ω/sq (the most common and practical range)Conductivity range: < 10⁴ Ω/sqInsulation range: > 10¹² Ω/sq (ordinary PI tape)Adhesive type: Silicone pressure-sensitive adhesive is the mainstream due to its best high-temperature resistance; there are also acrylic adhesives, etc.Main application scenarios (specific occasions to address electrostatic issues) PCB/PCBA manufacturing process protection:During the SMT (Surface Mount Technology) and wave soldering processes, it is used to cover gold fingers, specific solder pads, or connectors to prevent solder splatter and electrostatic discharge. After soldering, it can be easily peeled off without leaving any residual adhesive.Cover sensitive areas during circuit board testing and transportation.FPC (Flexible Printed Circuit) manufacturing:Used as a cover film or reinforcement plate for fixation, it protects the circuitry during high-temperature pressing (lamination) while also discharging static electricity.Semiconductor and chip packaging:Used for temporary fixation and protection in processes such as wafer cutting, chip mounting, and wire bonding, to prevent minor ESD damage that could lead to chip failure.Lithium battery manufacturing:Used for tab insulation and fixation during the winding or lamination process of battery cells, as well as insulation protection for battery packs, it meets both high temperature resistance and anti-static requirements, preventing internal short circuits.Aerospace and military electronics:Used for cable bundling, insulation, and static control in situations with extreme temperatures and high reliability requirements.Differentiating Features from Ordinary PI Tape and Other Tapes: Anti-static PI Tape, Ordinary PI Tape (Insulating), PET Tape Core Functions: High Temperature Resistance + Anti-static, High Temperature Resistance + High Insulation, High Strength Stability + Insulation Temperature Resistance Levels: Extremely High (260°C+), Extremely High (260°C+), Medium-High (120-150°C) Surface Resistance: 10⁴~10¹¹ Ω/sq (Controllable), >10¹² Ω/sq (Insulating), >10¹² Ω/sq (Insulating) Typical Uses: Anti-static solder masking, chip packaging, general high temperature insulation, electrical wrapping, screen bonding, nameplate pasting Pricing: Highest, Very High, Medium Buying Points and Brand References: Clarify Anti-static Level Requirements:Do you require electrostatic shielding (to prevent external electrostatic interference) or electrostatic discharge (to conduct away the charges generated by the product itself)? This determines the range of surface resistivity you need. The most common range is 10⁶~10⁹ Ω/sq.Confirm that the temperature resistance matches the process:What is the maximum temperature for your process? Can the adhesive withstand it? Silicone tape has good heat resistance but may have low initial adhesion; acrylic tape has strong adhesion but slightly inferior heat resistance.Pay attention to peel force and residual adhesive:Especially after solder masking applications, clean peeling without residue is required. Choosing a high-quality adhesive system is crucial.Other performance:Is UL certification (such as UL 94 V-0 flame retardant rating) required?Is solvent resistance (such as flux resistance) required?

Quick search for technical parameters of mainstream productsAccording to information from multiple manufacturers, the typical "heating joint" on the market uses fiberglass cloth tape, and its core parameters are shown in the following table:Parameter Type Typical Value/Description Data SourceBase material alkali free glass fiber clothThe adhesive type is mainly organic silicon pressure-sensitive adhesive, and there are also acrylic pressure-sensitive adhesivesThe thickness of the product is usually between 0.17mm and 0.22mmThe long-term temperature resistance is generally around 220 ° C, and some products can reach 260 ° CHigh tensile strength, such as ≥ 420 N/25mm or 600 N/25mmGood insulation performance, with flame retardancy and electrical insulation (H-level)2. Selection suggestions for different types of productsAccording to specific application requirements, you can choose from the following types:Pursuing permanent and high-strength bonding (such as composite structural bonding):Recommendation: Choose "thermosetting" or "thermosetting" glass cloth tape. This type of tape undergoes a chemical reaction after heating, forming a stronger and more durable bond, suitable for scenarios such as transformers and motor coils that require long-term reliable fixation.Pursuing convenient operation, temporary fixation or wrapping (such as fixation in heating processes, cable joint wrapping):Recommendation: Choose glass cloth tape coated with silicone pressure-sensitive adhesive. It only requires finger pressure to adhere, and heating (such as using heating tools) can further soften the gel, making it better adhere to the irregular surface, achieving a firm and residue free fixation. Especially suitable for wrapping mine cables, high-temperature coils, etc.Double sided bonding or special adhesive requirements are required (such as fixing nameplates, irregular parts):Recommendation: Consider double-sided glass cloth tape. For example, some manufacturers offer products with different viscosities on A/B sides (weak adhesion on one side and strong adhesion on the other), which can adapt to more complex production process requirements.3. Procurement and Channel ReferenceThese products are mostly industrial products, and you can purchase and consult through the following channels:Online B2B platforms, such as Alibaba International, have a large number of suppliers who can be screened based on product parameters and user evaluations.Professional tape manufacturers: Kunshan Yaheng Electronic Technology, Suzhou Changying Electronic Technology, Penglai Xicheng Insulation Materials, Suzhou Yunqi Adhesive Products and other companies mentioned in the search results are all professional manufacturers of such products. You can directly contact them for technical support or samples.Brand Agent: If you prefer international brands, you can look for authorized agents for similar models of adhesive tape (such as 3M 27 #, 3M 69 #) from 3M Company.To summarize: If your application is permanent structural bonding, you can focus on "thermosetting" silicone tape; If it is a field joint or fixation that requires flexible operation, then "pressure-sensitive" silicone glass cloth tape would be a more suitable choice. Before placing an order, it is best to contact the supplier to confirm whether the specific curing conditions and temperature resistance of the product fully meet your requirements

Anti-static gold finger tape

Anti static gold finger tape is essentially a special tape that adds anti-static (ESD) function on the basis of ordinary gold finger tape (polyimide tape). It is mainly used in the field of electronic manufacturing and maintenance, protecting precision electronic components while preventing static electricity accumulation from causing damage to the components.🛡️ What is it?Its core is polyimide film (PI film), which is an excellent engineering plastic with inherent characteristics such as high and low temperature resistance and electrical insulation. Anti static adhesive tape is based on this and modified through special processes or materials to control its surface resistance within a specific range (usually between 10 ⁹ and 10 ¹² Ω), thereby gently conducting static electricity away and avoiding electrostatic discharge (ESD) from penetrating sensitive electronic chips.📝 Core parametersThe following table summarizes the main performance parameters of anti-static gold finger tape for your quick understanding:Typical characteristics/numerical descriptions of parameter dimensionsThe substrate polyimide (PI) provides the basic properties of high temperature resistance and insulation, and its color is usually brown or amber.The long-term temperature resistance is 260 ℃, and the short-term temperature resistance is 300 ℃. It can withstand high temperature processes such as reflow soldering and wave soldering without melting or deformation.The surface resistance of anti-static performance is 10 ⁹~10 ¹² Ω, which meets the key indicators of ESD standards and ensures safe dissipation of static electricity, rather than instantaneous conduction or insulation accumulation of charges.The silicone pressure-sensitive adhesive has moderate adhesive properties and can firmly adhere at high temperatures. It is also not easy to residue after tearing off.The thickness is usually very thin between 0.05mm and 0.08mm, suitable for tight fitting of precision components.The insulation withstand voltage can reach over 5KV, providing good electrical insulation protection and preventing short circuits.🔧 Main application scenariosIts core value lies in "protection", mainly used in the following scenarios:PCB soldering protection: During SMT (surface mount technology) reflow soldering or wave soldering, it is attached to the gold fingers of the circuit board to prevent contamination or oxidation by solder.Precision electronic maintenance: used in the maintenance of mobile phones, tablets, computers, etc., to temporarily protect sensitive areas such as battery contacts, motherboard interfaces, and cable sockets. The anti-static function is crucial here, as it can prevent the breakdown of precision CPUs, memory chips, etc. by static electricity carried by the human body or tools during the maintenance process.Lithium battery manufacturing: used for insulation and fixation of lithium battery cell lugs.Electronic component insulation: used for high-temperature insulation wrapping of components such as transformers, motors, coils, etc.💡 How to choose correctly?To choose truly useful anti-static tape, don't just look at the color, pay attention to the following points:Confirmation identification: The product must be clearly labeled with the words "anti-static", "ESD" or "Anti static". Only known as "golden finger tape" or "high-temperature tape" usually does not have this function. For example, the well-known brand 3M's 5413 series is a recognized anti-static gold finger tape product.Check parameters: You can refer to the product manual, and the surface resistance value should be between 10 ⁶ and 10 ¹¹ Ω (anti-static standard range).Select specifications based on the scenario:Personal repair or small batch: Purchase a regular length of 5-33 meters, and choose the width according to the protection area. For example, 5mm or 8mm width is suitable for protecting phone battery contacts, while 10mm to 25mm width is suitable for protecting PCB metal fingers.Industrial production: can be purchased in bulk, and specifications (width, length, inner diameter of the tube core) can usually be customized.
