Removing Markings from Devices

Electronics Forum | Thu May 01 16:41:54 EDT 2008 | chrisawallace

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

DEK_265LT had been turn off and on by itsefl couple of time yesterday,and then off for good. I check the power going in to machine to the switch,got power to it,then power out to that little green box but there wasn't any power out put from that lit

Leaded and Lead Free BGA's on hte same board

Electronics Forum | Thu May 01 14:25:31 EDT 2008 | ck_the_flip

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

Electronics Forum | Thu May 01 15:42:53 EDT 2008 | ck_the_flip

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.

No flow underfills

Electronics Forum | Thu May 01 09:09:31 EDT 2008 | scottp

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

Pb-Free BGA on SnPb Assemblies

Electronics Forum | Thu May 01 11:26:22 EDT 2008 | cdsullivan

Thank you for the reply. We do build SnPb assemblies as well as Pb-Free. I am aware of the Silver paste. However, what impact is there with reflowing SnPb components with a max temp of say 220C when using the higher Pb-Free temps?
