I presume you are looking at low melting point solders. Firstly, I would consider running BOTH sides with the same paste - this will cut down the opportunities for a mix up with rework or retro-fit. Secondly, check that there is a cored wire availabl

Hi all! Heres wishing everyone a Happy & Prosperous 2008!! We are a small OEM/CM that use Ni tabs in our design/applications. We have a request to use Stainless steel to reduce/eliminate the Ni content. Can Stainless steel be soldered? If yes, is ou

A PCBA contains a couple of parts that are not sealed and can't be water washed. We hand solder these with no-clean after everything else is water washed. The designer says the no-clean residue must be completely removed so that it will not affect

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

Has anyone tried a PS-800E made by OKi Metcal? I have been looking at them, it looks like a good Iron, but I would like to know how these are actually working in the field not just some sales pitch by someone getting a commision. Thanks, Wayne

I am a PCB Designer and I have to put a note on the assembly drawing to tell the assembler how to clean the board. This is new to me. Here is a sample note. Can someone give me some feedback on it? "Use water washable, no clean solder paste for t

I happen to agree with Vlad and I'm not in the same business as him. Randomly turning knobs isn't the way to solve a problem. Do a proper analysis and let the parts tell you what's happening. Seems like a lot of problems people post on this forum

Well, it depends on what kind of evidence you'd have. I dealt with quite a few of them including a VERY big one (a chip maker) and all of them would try to prove you wrong, until they realize that the data you have speak for themselve. Saying data I

Hi Eyal, Sure you can do that. You might be able to use your "typical" reflow profile for eutectic, or tweak it slightly. it's a good idea to do a trial run and then get a couple of components cross-sectioned and checked for the microstructure of th

Have seen similar problem before with regards the MSD being the cause. But also seen similar defects being found at functional test as the in-circuit test was injecting to much current during test. The devices were walking wounded afterwards. The in
