Apoligies Steve if I did not explain myself clearly. We have made the same design using the same RoHs compliant components (which I am assured by the suppliers are process temperature capable) with both lead and lead free solder. Without wishing to

Recently I was given a bad Bios Link from Toshiba which fried my Bios and now my laptop boots to a black screen. I recently unsoldered and removed the existing Bios chip and have ordered anotherfor replacement. Unfortunately while removing, i damag

It all has to do with charges being drained. IIRC the pink stuff won't build up a charge but doesn't drain it well. As for the need for mats, how are charges being drained now? I don't think you can have no charges building up. With ESD all you can

I agree with Stephen there! Or maybe we just didn't care enough about looking into it in the COLD profile days! Back to df: I don't think any manufacturer is going to give you a tolerance level, they'll stick with what they've told you -225. If it's

Ted Dangelmayer's book [ESD Program Management: A Realistic Approach to Continuous Measurable Improvement in Static Control; Dangelmayer, T; Kluwer Academic Pub 1999 e2; 0412136716] is excellent. Often, ESD supplies sales-types use the "Chicken Littl

We use random local fids on our Universal equipment - (they don't create a centerline placement point). On your equip., maybe you could try to shoot/dive-bomb the QFP(s) all by themselves using the 2 "random" local fids as your baseline reference po

Something that I find unusual in some of the replies is the fact that local fids that are randomly dropped around the quad don't do anything for assisting the alignment of said quad. The only way that I am aware of the local fids being useful is if t

Hi Steve- Not being familiar with CS machines as you are...but do you need to use fiducials for a 20mil QFP? If so...OK...just curious. Also, it would be nice to know the reference point that the board designer uses... Board corner, Centroid, part c

Good morning/afternoon/evening everyone! I am seeking the assistance/guidance of anyone who has had practical experience with placing, soldering, and rework of this particular component. One of our customers is looking to use this component on quit

I assuming that you already have checked the fuses? Also, check all the power: +5V, +12V, +-24V, etc. We had to change our PSU once, after a major power-drop due to a thunderstorm. But you should be ok if you can pinpoint what type of voltage you are
