Several points are: * There�s quite a bit of background on IMC in the fine SMTnet Archives. I�ll try not to duplicate it. * If you have a smooth and well-formed solder connection using fairly common materials, you assuredly will have IMC. Any evide

Dave, Like everyone else,I don't generally allow it. If only one component is off and that head is doing another component of the same type with no probs, ( pick-up is OK ) then I just say "don't ask me - move the bloody thing". I usually find it's

I always look at the support structure. This is where I feel the real Dollars and cents come into play. Sure you can calculate the derated value over months or years. But If your machine is in a "machine down" situation the derated value does not cha

I have recently signed onto a company with very little board assembly experience. I am trying to develop a process control and continuous process improvement program for a new surface mount line, but have run into several people who are not really i

I think this licensing thing was a poor decision to begin with. I can understand the reasoning for GenRad to issue a software license, to protect their product against cloning. Why Universal followed could have been caused by the take over and the

Hi, I agree that professional-role accountability (QA, Process, Manufacturing, Materials, etc...) is of paramount importance. in fact nothing yielding results, gets to be done without followup in continual improvement action unless individuals are

Being in the line of BGA rework and having performed much rework on boards that go into military planes, I can give you an opinion from a practical background rather than an in depth study. Basically BGA's have caused many of my customers big headac

You can't control what you don't measure. You have provided very little detail other than post reflow costs are high. What defects are attributed to problems experienced prior to reflow? Are these random or recurring defects? You will need to put ea
