Finding MSL Levels

Electronics Forum | Mon Jun 06 14:21:14 EDT 2011 | rwyman

A reputable supplier will identify the level CLEARLY on the packaging and in the datasheet as well. If they are KNOWN to be MSDs, I'd be suspicious if they aren't marked. Or, they may not be MSDs. I don't think it's required to ID them as "M1" if n

ICT testing to improve yields

Electronics Forum | Mon Aug 27 08:08:20 EDT 2012 | rgduval

An ICT solution seems to be overkill for what you've described. What kind of volumes are you hand building? How many components are not marked? What is your current yield with the process you are using? What is/was your yield prior to implementing m

Hello guys I am back! Guys I have a problem with the laser marker here, we use the laser to mark a 2D barcode on the pcbs for traceability, but for some reason since yesterday every time it tries to connect to the database to get the serial codes an

Barcode pcbs for traceability

Electronics Forum | Thu Feb 25 17:34:21 EST 2021 | roblackey

I think you are going to struggle without a laser designed for PCBAs (Asys, XJ Link etc) as they are designed to just burn into the resist and give good defininition, then readback to know you have a good mark. Key tips for our experience: Datama

No need to make rocket science out it. Buy an AOI mchine. If that's too expensive, scrap a board to use as a sample. Can't do that, use a digital camera and snap a couple pix of a good board and make some kick ass work instructions to use. Can't

RoHS Board Delamination

Mark, The pcb manufacturer recommended we bake the boards , so we did. I even weighed a batch before and after and seen slight decrease possibly 0.1g in weight. However we still seen some delam after all this. I am confident our issue has nothing to

Hi John, We picked up a used laser marker (Asys ALS03) last year for around 30K euros and it has done approx 2M codes (we use 6mm square QR) in the last year without fault - it reads them all back to confirm which is handy. We also use labels, and

This is getting to be a more common practice, especially with the application of a 2-D bar code directly to the board (via laser, ink jet,etc.) Some really major companies are jumping on the bandwagon because it also allows treating each board as a l
