The diode doesn�t appear completely broken. It takes a bit white color (cristal break, I think), instead of the normal red/orange. It works like a 20K-200K ohm resistor. !The diode can be working properly and sometimes change to bad! I think it may

Hello, We are using FR-2 in boards 15x10cm size, with SMD and thru hole components (about 100 SMD and 50 thru hole). We have some "rare" problems (flex cracks or caps, diodes, and so on). Would we improve something by using CEM-1 instead of FR-2?? Mo

If it happened after a high energy event then maybe the root cause is a lack of TVS diodes in the design of the circuit. Or if they are ceramic diodes then maybe they are too close to the edge and have flex cracks.

We experiences some failures on PCB assemblies from the field when a methacrylate epoxy adhesive was used to secure some through-hole components to pcb board as reinforcement against vibration. During application, the epoxy covered some smaller SMT c
