SMT Gasket

SMT EMI Gasket (SMT Ground Contact/Pad, PCB Ground Contact) is a grounding gasket that prevents malfunction due to electromagnetic waves generated inside electronic devices, attenuates electromagnetic noise, and grounds PCB to outer case.
Reflow soldering is possible up to 260℃ by using material with excellent heat resistance.
Packaged with reel tape to enable automatic surface mounting.
Can be used as a touch switch gasket, a touch sensor gasket, etc.

Stable cube shape, and very soft & elastic by using a sponge core.
- Manufactured in a variety of sizes compared to silicone or metal ground contacts
- Neither bent nor broken like a finger strip
- No fear of hardening or generating siloxane like silicone-core type
- Soft sponge material does not warp PCB nor deform the device
Excellent electrical conductivity and low surface resistance
Excellent resilience, free from bent or broken problem (Hardness adjustable)
SMT(surface mounting) available and manual soldering compatible
RoHS Compliant, UL94V-0, Halogen Free

SMT Gasket is used for EMI shielding and grounding by attaching to PCB of LCD module. It’s usually used several pieces on PCB to maximize EMI shielding and grounding effectiveness and its positions on PCB are reflected in PCB circuit design phase.
Provided in reel typed career packages suitable for SMT.

Touch sensor gasket (touch switch gasket) functions as an electrode connecting display panel and PCB in the electrostatic touch input method, and is mainly suitable for touch switches of home appliances and industrial devices.
Spring contact and touch rod method require manual soldering, causing poor productivity, but SMF gasket's automatic surface mounting can improve productivity and reduce process cost.
Cost saving is expected by replacing the expensive touch grid method.
This gasket does not stress PCB/Panel thanks to its super softness and elasticity and has high reliability against corrosion.
