If I brief shifting, I checked the component before it enter the reflow oven and saw that the IC is perfectly aligned on the pads but when it comes out from the oven the IC is floated on the pads. The floating is irregular and the IC is shifted away

No recommendations ... Too many friends in the trade Fair enough. Dave, I'd like to thank you for making your previous comment, which got me over my irrational fear of water-washable paste. My first tube wasn't the "no-clean-washable" kind -- coul

From what you described of what you seeing from the slow motion is that the part is not actually "placed"; it's more like drops on top of the paste, so it's floating on top only which vibrations would cause it to slips away. Even though I am not fa

You weren�t clear but I assume the problem is not widely distributed and affects only a few parts on each board. Do this trick: * Cut a ~1� piece of fairly serious wire, like 18 or 12 AWG. * Strip the insulation. * Gear-up with gloves, glasses, and

Fred: I'm tryin' my darndest to be good, because, for whatever stupid reason, I feel that you're making an honest inquiry and not just floating something to find the biggest sucker. If only Earl was still here, he'd always bite on stuff like this.

| Does anyone have any recommendations on spray fluxers? Are there major differences between the high priced ultrasonic machines to the low priced flux/air spraying machines? We are going to be spraying an OA flux with 11% solids content. Are there a

Do you design or define PCB layouts? If so circuit board, what rules and checks do you have in place to make sure your results are... optimal? Over the years, I've created a PCB design checklist to keep me out of trouble. I share these nuggets with m
