Has anyone seen or put together a good collection of proper handling procedures for components and PCB's? I realize a lot of it is no-brainer stuff, but I need some depth for a training class we are putting together. This would include ESD, Moisture

We are looking at setting up a memory module conveyor belt with a stacker and de-stacker. I will need to handle DDR3 and DDR4 Long DIMM and SODIMM. I will be mounting an image camera under and over the modules. Looks like an edge conveyor would be be

Of course a new machine out of the box should perform at a realistic Sigma level and it's not unfair to hold a machine manufacturer true to their claims. However, even if a new machine does meet the criteria on day 1, the numbers will be constantly c

We recently purchased a Mirtec AOI machine, it take a bit to program but overall we are pleased. The machine has a downward looking camera, we have had some issues with the machine not catching opens. When a IC has it's legs bent straight up off th

I'd be surprised if CCGA leads were getting bent or tilted during the reflow soldering process. If they were bent during handling, that would be less surprising. 235*C on the body for a minimum peak temperature of 208*C at the connecting leads does

Hi Dave, Yes the lead was there before reflow. After reflow it has bent inside. The component was inspected before placement. We are unable to analyze, what might have went wrong. Regards, Ameen

Did you check the pin location accuracy before placement? I mean if possible pin was hit or misaligned a little before placement, so the pin cannot inserted in hole then bent. And maybe you need contact your component supplier to study together.

Thanks to those that responded. I eliminated the light curtain problem. The metal plate the light curtain pcb bolts to was bent. I had it aligned in our machine shop and it worked properly. I forgot to mention the error was pooping up with no fee

thanks dave .. I have one more query on the same CCGA. What are the chances of the CCGA lead getting bent or tilt during reflow soldering process. Concern : to achieve the minimum peak temperature of 208 deg C at the connecting leads. On bod
