Electronics
As electronic devices continue to evolve toward greater thinness & lightweight, their internal structures face increasingly complex challenges — ranging from bonding and insulation to thermal management, signal shielding. From smartphones and laptops to wearables and smart home systems, specialty tapes have become more than just adhesives.
Structural Fixation
Application Purpose:
- Secure components in their intended positions
Application Area:
- Display bonding & fixation, to secure display panel to frame structure
- Fixation of battery module, bonding between battery module and housing
- Components fixation
- Marking & labeling
Applicable Material Selection:
- Double-Sided Tape High bonding performance to various substrates, high shear strength, good die-cuttability, clean assembly Double-Sided Differential
- Double-Sided Differential Tape Different adhesives are designed for bonding to different substrates, or different adhesion levels are designed for different applications
Best in:
- Display module bonding to frame, battery module fixation to housing, FPC or component fixation, general mounting
- Bonding of dissimilar materials
Insulation
Application Purpose:
- Prevents unwanted current flow, enhances safety by reducing short-circuit risks, and protects sensitive components
Application Area:
- Around the battery module, insulating the lithium battery from the main board
- Applied beneath or on the reverse side of the FPC to insulate it from the metal base or mid-frame.
- Located near the connector and charging port to block electrical conduction between metal components and the device housing.
- At the interface between the display and the main board, serving as an insulating layer to prevent conductive contact or friction
Applicable Material Selection:
- PI (polyimide) PSA Tape High dielectric strength, high temperature resistance, excellent chemical resistance, and flame-retardant PET PSA
- Flame-retardant PET PSA Tape Good dielectric strength, good mechanical strength, good temperature resistance
Best for:
- Lithium-battery insulation, high-temperature masking, FPC protection, EV applications, requiring extreme durability.
- General insulation, bundling, EMI masking, electronic component protection
EMI (electromagnetic interference shielding)
Application Purpose:
- Prevents unwanted electromagnetic interference and maintain signal stability.
Application Area:
- At the contact area between the PCB and the metal housing, preventing high-frequency signals from radiating from the PCB into the metal housing
- Positioned near antenna modules (including NFC, Wi-Fi, GPS, and 5G antennas) to mitigate interference from adjacent components
- On the back side or along the edges of the display module (LCD/OLED), preventing display signal lines from causing interference to the main board or antenna
- In the motor module, suppressing electromagnetic noise generated during motor operation
Applicable Material Selection:
- Copper Foil PSA Tape Excellent electrical conductivity, extremely low contact resistance, excellent shielding effectiveness over a wide frequency range
- Aluminum Foil PSA Tape Soft & highly flexible High electrical conductivity, excellent shielding effectiveness from mid-to-high frequency range (100MHz ~ 3GHz)
- Conductive Fabric PSA Tape Good electrical conductivity, low & stable contact resistance due to nickel-plated surface which is resistant to oxidation, good shielding effectiveness in high frequency ranges, durable & conformable
- Conductive Foam PSA Tape Good electrical conductivity after compression, good shielding effectiveness, excellent compression
Best in:
- PCB/ FPC grounding reinforcement high frequency signal areas, areas that require bending or compression
- metal housings or mechanical parts to provide large-area EMI shielding
- Wrapping around foam to serve as EMI grounding pads or strips, for grounding purpose, modules that require bending
- Serves as an EMI cushioning pad or grounding pad (EMI gasket), provides gap filling to compensate height difference in device housing while providing a conductive path
Cushioning / Shock Absorption
Application Purpose:
- To protect fragile modules; absorb impact and reduce compression between components
Application Area:
- Applied around the battery module to fill the gaps between the battery and the housing, preventing vibration and unwanted noise
- Applied along the display module frame to reduce assembly stress and protect the glass module
- Applied around the motor module to absorb vibration, reduce noise
- Used for gap filling between modules to prevent contact and friction
Applicable Material Selection:
- PU Foam PSA Tape Open cell structure, excellent softness & resilience, excellent cushioning and vibration damping, low compression force, long-term compression stability
- PE Foam PSA Tape Closed cell structure, water & dust proof, good chemical resistance, ideal for gap filling & spacing & structural positioning
Best for:
- Cushioning along display module frames, around battery modules to reduce vibration & noise, areas requiring repeated compression
Best in:
- Gap filling between modules, Structural positioning & spacing, large-area applications
Light Shielding
Application Purpose:
- Blocks stray or light leakage to improve display quality while protecting internal components from light interference
Application Area:
- In the display module backlight area, shielding the gaps between the backlight components (such as the light guide plate or LED strips) and surrounding mechanical parts
- Applied around the camera module to prevent background light from entering the lens
- Applied along the edges of the keyboard backlight module to block light leakage into the internal structure or surrounding display area
- Applied around the light sensor to block non-direct or stray light that may interfere with sensor operation
Applicable Material Selection:
- Black / Matte Black PET Masking Tape Excellent light shielding, good temperature resistance, matte black color satisfies cosmetic requirement
- Black / Matte Black PI Masking Tape Excellent light shielding, superior temperature resistance with high dimensional stability, matte black color satisfies cosmetic requirement
Best in:
- General light blocking applications under moderate temperature conditions, large-area applications
- Precision optical applications such as camera modules, light sensors, high-end display modules, and areas that require high temperature resistance
