You can browse the product catalog available here or contact our engineers through our customer service department to customize SMT foam gaskets to your specific cross-sectional shape, cut to length, or unique die-cut shapes.
The conductive SMT Gasket features an extruded silicone core wrapped with a conductive layer such as conductive PI film or metal foil. It represents the earliest and most widely adopted SMT gasket design, offering reliable conductivity and stable compression performance.
The SMT foam Gasket utilizes a modified open-cell silicone foam core enclosed by a conductive layer. This structure provides excellent compression adaptability and low contact pressure, making it suitable for high-deformation, low-stress applications.
The PCB SMT Gasket is constructed with a closed-cell silicone foam core coated with a conductive layer, typically conductive PI film or metal foil. It is ideal for general EMI shielding requirements and is commonly attached using adhesive without soldering.
This EMI SMT Gasket combines an extruded silicone foam with a conductive outer layer, designed to prevent side buckling after compression. It is mainly applied in folded or angled configurations requiring high dimensional stability and resilience.
The conductive SMT gasket adopts an ultra-thin, miniaturized profile with conductive PI film applied only on the soldering surface. It enables reliable SMT grounding with minimal height and footprint, ideal for high-density and space-constrained PCB designs.
