Resistance: 12V voltage, the resistance of 1.2 ohms
Size: 220mm * 220mm * 3mm hole spacing 214mm
process: aluminum plate
1, the whole board full gold process, the cost is much higher than the spray tin plate!
2, the whole board after optical short circuit, open circuit detection. 3, heating table and aluminum substrate into one, better temperature stability. 4, the new circuit, power supply power stability. 12V connection: a line then 1, another line at the same time then 2,3
