PCB Repair Precautions-Maintenance

PCB Repair Precautions

The LIFEPAK 9A defibrillator/monitor uses multilayer PCBs which are not easily repaired. They consist of alternate layers of conductive patterns and insulating material bonded together and interconnected with plated-through holes. The internal layers and connection points are quickly damaged by too much heat, rendering the entire PCB useless. Therefore, it is recommended that all multilayer PCBs be returned to Physio-Control for repair or replacement.

CAUTION

Possible PCB damage. Improper handing can easily damage the PCBs beyond repair. Plated-through holes connecting the circuitry on two sides of the PCB can be damaged by too much heat.

NOTE:

Before attempting any PCB repair, contact Physio-Control. Customer PCB repair may endanger any applicable PCB exchange agreement or other warranty.
