All: I am interested in how process engineers are both removing and adding markings to active devices. We have a job where we have to both remove the markings of and the re-mark SOICs. The markings on the devices look like they are pad or ink jet p

At my last company, we sent specific key components out for remarking to help protect our intellectual property as it is much more difficult to copy a design if you don't know what the components are. (Yes, I understand this is not foolproof but rath

I just got done analyzing an old piece of gear with relabeled parts. We had a schematic of the boards, with no info other than the OEM's part numbers and the way the chips were interconnected. It took me no more than 15 minutes with a couple databo

You're not the only one. We just got done with a batch of ICs that had a high reject rate at placement. The machine was rejecting about 70% of the parts because it didn't recognize the part. The reason it didn't recognize the part was due to the f

Most white papers, like this one http://members.ipc.org/ipclogin/ipcmembers/IPC/Route/0706/0706techpaper.pdf, have written that lead contamination in a lead-free solder joint leads to all sorts of reliability problems. Consensus is that, if the cont

Yes, the authors do give the caveat that small amount of lead contamination in a SAC/Lead-Free system is tolerated provided the Pb-BGA has sufficiently reflowed. This verbiage is on the bottom of Figure 10. For my own peace-of-mind, I would send yo

Hi Jim, We had a similar problem with an AP-27. You could try to jumper the wires which lead in to the reed switch. Failing that you could swap out the opto module for this, in our machine it's located in rack 2-15. Rgards, Kev.

I looked at some no flow underfills about 5 years ago and they weren't quite ready for prime time yet. It's time to give it another look and I'm wondering if anyone is using them in production and how it's working. I'm looking at them for reducing
