A 2 layer PCB stackup is a combination of two layers of copper separated by a dielectric material. They are generally called the upper layer and lower layer with dielectric
Shengyi S1141 features a low glass transition temperature (Tg), the transition temperature of the material is precisely 140 degrees centigrade.With a dielectric constant (4.4 @1GHz), The Dielectric Constant (Dk) of
The double-sided "thermoelectric separation" copper substrate produced by QFPCB has achieved a leap in thermal conductivity. Utilizing a special raised structure for heat dissipation, the substrate boasts a thermal conductivity
