I've recently seen some TO-220 FETs that appear to be counterfeit parts that have had the marked area resurfaced and remarked with a false part number. I don't know much about semiconductor manufacturing, and I just want to know if there is a type o

Yep, lots of ways to do it and lots of ways to check it. Immediately blacklist the supplier who sent them in to your business. Manufacturers don't need to do this. I've heard excuses such as remarked due to automotive qualification, but normally di

I know nothing about Xbox specific rework, but have a lot of experience with PCB repairs. "...maybe think its a bad idea now not knowing what im doing" Don't get discouraged, it's a learning process. If it was that easy everyone would be doing it.

HO what a BIG twit I am, for wasting your time (and a few hours myself trying many options on google). It is not EG84 it must be E684, (I will have another look next time I go back to work) you see I know the value, I thought it was a new secret co

What is changing the marking on the part? * Is flux residue coating the part to change the the way light reflects from the part surface? [Run a board with tape on the part, then remove the tape prior to AOI] * Is the heat of the oven changing the mar

Russ, this post doesn't specificly address your original post but I thought it is relevant to your situation and future production. I have been having problems with voids using Kester's R596L paste. I contacted them for a solution to my problem. T

In a past life I used a Swam Blaster from Crystal Mark with the media from them as well. I used it on Humiseal 1A31 and 1B31 (I think those were the products, it's been a little while). This machine and material were awesome IMO. Made CC removal a
