01. SMT Gasket

SMT Conductive Foam Gasket consists of a highly elastic silicone core encased in a surface-coated conductive metal PET or PI. This SMT conductive foam provides a reliable grounding point on printed circuit boards, offering a new type of solderable conductive foam.

Advantages of Our Process Compared to Traditional Methods
01
Special Perforation Structure
The unique perforation structure ensures that the foam maintains its shape without significant distortion or tilt under compression. This design addresses issues such as poor contact, uneven stress distribution, and cracking in the conductive shielding layer.
02
Enhanced Silicone Bonding
The silicone strips undergo surface treatment, which improves adhesion to the conductive layer. The special perforation design ensures even stress distribution during molding, resulting in better encapsulation and greater bond strength.
03
Reduced Complexity and Cost
Our process lowers the difficulty of integrating conductive layers and silicone strips, thereby reducing production costs.
