The importance of press-fit cushion customization
In the world of PCB manufacturing, press-fit cushioning pads serve as critical auxiliary materials, and their performance directly impacts the quality of the final product. With the development of electronic devices in the direction of high performance and miniaturization, standardized cushion products are no longer difficult to meet diverse production needs. As a professional press-fit cushion product manufacturer, we provide comprehensive press-fit cushion customization services to help customers solve production problems under special process conditions.
Customized cushioning can accurately match the special requirements of different PCB types and different pressing equipment, playing a key role in improving product yield and reducing production costs. Our data shows that customers who use custom cushioning have an average yield rate of 15%-20% and equipment maintenance costs have been reduced by more than 30%.
Key considerations for press-fit cushion customization
Substrate selection
Depending on the specific needs of our customers, we offer a variety of substrate options:
Aramid fiber substrate: excellent high-temperature resistance, suitable for high-temperature processes such as high-frequency plates
Glass fiber reinforced substrate: high mechanical strength, suitable for pressing thick copper plates
Composite fiber substrates: Balance performance and economy for most multilayer boards
Special ceramic substrates: ultra-low coefficient of thermal expansion to meet the requirements of ultra-high precision
Thickness and density design
The thickness and density of the cushion directly affect the pressure transfer effect:
Standard thickness: 0.5mm-3.0mm range optional
High-density design: suitable for high-pressure processes (>500psi)
Gradient Density Design: Addresses edge effects
Composite thickness design: to meet special stacking needs
Surface treatment process
We offer a variety of surface treatment solutions for different application scenarios:
Glossy finishing: ensure the surface finish of the PCB
Texturing: Improves exhaust performance
Stick-resistant coating: prevents resin from sticking
Anti-static treatment: meets cleanroom requirements
Typical application scenarios for custom press-fit cushioning
High-density interconnect board (HDI) applications
HDI boards have extremely high surface flatness requirements, and the ultra-precision cushioning we have developed is:
Surface roughness < 0.5 μm
