Method One: look after the amount
Tools: multimeter, magnifying glass
When the vertical injection molding machine circuit board holding the piece to be repaired, the good habits first, and should be visually, if necessary, even with a magnifying glass to see it?
Mainly to see:
1, vertical injection molding machine circuit board if there is broken;vertical injection molding machine
2, discrete components such as resistors, electrolytic capacitors, inductors, diodes, transistors and other time off phenomenon exists;
3, PCB vertical injection molding machine circuit board connecting line if there are broken, adhesions;
4, vertical injection molding machine circuit board if anyone repaired? Which components moving too? Whether there Weld, weld, and other operational aspects of the anti-plug failure
