Single-sided PCB with Carbon

What you see now is the air conditioner remote control circuit board produced by our fWhat you see now is the air conditioner remote control circuit board produced by our factory. The manufacturing process is single-sided circuit printing plus carbon film buttons. If the customer requires greater circuit accuracy, the exposure process is used. The circuit board surface anti-oxidation process adopts OSP. The advantages of this type of single-sided carbon membrane are that the production cycle is short, the cost is not high, the circuit has strong anti-oxidation ability, and the labor and material consumption are not high.
