Seems to me you might want to be talking to your board shop. Items like score depth and reconfiguring the panel should probably be discussed. If this is a labor only job I would discuss the problem with your customer, in turn, he can talk to the boar

I am not sure about the way the board is made, but I am sure that if you change your handling system to a tray based board handling system you will reduce these problems to a manageable level. Tray carts and trays are clearly the industry standard m

Hi Lloyd! You mention "bad handling" as the cause of the PCB breakage... One way to convince operators to be careful in handling PCBs is to make them pay for the broken ones! If the fault is theirs, they should pay for it. If it's not their fault, fi

Claude, your not a manager by any chance are you?... you can't charge them for breaking them. Ok so yes there will be poor handling but if your going to fix the problem you have to look at teh route cause of it and fix that. You should be settign up

Have you tried profiling the board with temperature label or profiler thru wave? I reckon your pre-heat temperature might be too high either on top or bottom and cause the component to expand unevenly. Regards, xinxi

Is the components on the top or on the bottom of the pcb? Have you checked whether the temperature on pcb are too high when it pass through SW that it exceeds the limit that the components can take? Do check with the component manufacture for the te

Mikel: There's a lot of ways to break a glass diode. Poor material handling High placement force Thermal stress Board flex So, where is this damage occuring? Dave F

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
