First, you're correct. Trace repair and rework is not for the faint of heart or novices. Second, our "girls" prefer a dental drill type tool [Dremel Flexshaft], rather than the clumsy Dremel type from Wal-Mart. They also like a vice with a unversa

Umar - This is usually seen when the lead frame in the die attach is cut with a diamond saw instead of a lasar. We have seen this problem years ago from HP 7 segment displays. If you have Enviromental box (tenney box) you can temp cycle them from 0 d

What is the disadvantage of palladium plating instead of gold plating? I saw many advantage of palladium plating in term of hardness, wear resistance, and price but why most of the PCB Industries still use gold in PCB pad? Thank you

On an assembly reflowed in air saw the same thing: 0201's with a grainular solder joint, but 0402's and above with perfectly formed joints. Reflow profile all within acceptable tolerances. Reflowing in nitrogen solves this problem, but increases t

And pin outs of both. Once I saw a SOT-6 replaced with a miniSOT-6 (IIRC) The pin outs of the two parts were different. We did make an adaptor board and it wasn't too bad. We populated a panel of the adaptor boards, depanelized them and put them in t

We have fought with cut-tape way too much. It's always a bad idea. We've tried a couple methods/devices for manual splice with limited success. Before you look into this I would ask them if they could supply you cut tape qty's inslusive of fairly

And why do you want to control the process? To prevent defects, I would think. Actually orginally the way I first saw SPC was to reduce inspection. If you are using SPC for plating thickness, you don't have to measure every piece to be confident the
