Oh dear, I tried not to respond but i couldn't help myself. Stop me if I go off into the woods. My guess, Chris, based on your fleeting reference to GF files, is that your SMT machines are Siemens Siplace. If this is so then package orientation def

Obviously you are not as experienced as you think so I will help you out a bit.You are correct on the size of the wrench. I was trying to recall from memory but the wrench size is 8mm. The odd size I recalled came from the other side of the wrench th

There are a lot of variables in BGA rework in general, and the switch to lead free has only magnified some of the sore spots. Perhaps with a little bit more information someone here can be of help. What is the size and thickness of the PCB? What

Hi, Can anyone help me on how to choose profile points in wave soldering...e.g. smallest like R, C, to biggest like transformer heatsink etc.... Are the thermo-couples supposed to be on top of the pcb or at the bottom touching the solder bath when fl
