How are companies handling lot tracking of parts, down to the serial number of the PCBA on which each component is being placed? We have customers who are needing information on Mfg. Lot numbers on mission critical product in the event of Manufact

Hello everyone. I'm looking for some general information on reel counters. We are trying to tighten our inventory counts, and rather than estimate a reel we're looking into getting an accurate count via a reel counter. So first, I'm wondering what

Hi, I think concept of inspection through AOI is changing. I am struck in confusion.Because some manufacturer say 3D inspection, with 1+4 cameras is ultimate solution. Orbotech also came with 13 cameras at once!Now some say, all these are eyewashing

I always fix thermocouples to pcb pads across its width. Then rotate it 180 degrees to check readings. If I am happy that the oven is giving results within a few degrees C then I'll crack on and set up a soldering profile. I am not sure what the oven

Jacki: That's exactly what we need to know, so that we can start slogging through this. [See we don't do well with broad, generalized questions. We don't have time to write dissertations. This is a task-oriented group.] Let's focus further: * Is

Erli, Thanks for your feedback. The BGA hybrids were baked before production. I had a particular date code that we dis-continued using. This date code was consistently voiding near or above 25%. The other date codes still produced voiding on ave

I am experiencing sporatic de-wettting issues, so I have been thinking about ways to clean fully assembled circuit boards that have open switches, contacts, etc. I also suspect that that plastic bodied components have residual silicone mold release

I'm sure you could buy everything you need to make your own stencils in-house for way less than 200K - lasercut or photochemical etch. If you have someone local with a typesetter of photoplotter , photoetch should be really cheap to set up. I've also
