What Is 4-layer Spray Tin FR4 Automotive PCB Circuit Board?
4-layer spray tin FR4 automotive PCB circuit board is a type of printed circuit board (PCB) that is specifically designed for automotive applications. It consists of multiple layers of FR4 material, which is a flame-retardant epoxy laminate commonly used as a base material for insulation in PCBs.
The term "spray tin" refers to the surface treatment of the PCB. Spray tin is one of the surface finishes used to protect the copper traces on the board from oxidation and provide a solderable surface. It involves applying a thin layer of tin onto the copper traces using a spray coating process.
