Basic description of the product
The PCB of the automatic transmission consists of a circuit layer, a heat insulation layer and a metal substrate. The circuit layer (ie, copper foil) is typically etched to form a printed circuit that connects the components of the component. Generally, the circuit layer is required to have a large current carrying capacity.
Insulation is the core technology of automatic transmissions. It is usually composed of a special polymer filled with a special ceramic, which has low heat resistance, excellent viscoelasticity, heat aging resistance, and mechanical and thermal stress resistance.
