I've known Mike Konrad for over 20 years. I like him. He is knowledgeable and generous in the giving of that knowledge. I have no issues with what he said in his vid. We should not get too overly twitchy when someone, sales-type or not, makes an eff

Not to be repetitious, I just don't remember if this has been said or not, I'm old, give me a break. Some people have found that DI water is too thick to properly remove flux residue under low stand-off components.

yep, Phil nailed it. Also, don't put them in all 4 corners, or if you do, don't place them symmetrically. And keep them far enough from the edge that rail clamps won't block them. And make sure to put them on BOTH sides of a double sided board. Th

Hi Recently have several components inside the machine covered with this yellow dust. It is visible that some components are almost obstructed after a week working. We never seen this kind of dirt inside the machines, and we don’t know the origin o
