In your video, it looks to me as though the bottom of the glass is too low, but, I can't tell for certain. As a general rule, keep the top of the wave no higher than the mid-point of the PCB. Top flow will take care of itself thanks to flux and cap

See. That's the connector that I thought it was. No, don't change your project!!! It sounds perfect. This will be a wonderful "learning experience" for you. You should get yourself a magnifying glass, some solder, and a soldering iron and go t

RC, I agree. I have tried to educate management as to the real benifits of height measurement. Our President attended a CEO meeting of some sort and was told that solder paste height measurement will solve all of the worlds problems. She then inquir

My experience with different size boards and pre-heaters. The perfect world (right?) you would saturate the complete pcb with bottom pre-heat. But it is difficult with repair and rework equipment, not to mention the expense and foot print of large pr

You're correct. It's a peculiar looking defect. With measling, we expect to see discrete white spots or crosses just below the surface of the base material. We don't see that here. We do see a similar condition at almost every PTH in the picture, a

Hello I'm just study PCB in my company. I found many Surface PCB have some contaminate and can not specify what it is. Size is around 2 mm2 . Sometime I send to supplier and they said it is solder paste or some dirty flux. please see contaminate1

Hey Bud: Thanks for the response the other day. We currently use "Jeff�s Method #2: The Drummel Tool." Short answer to your brother is ... yes, probably. Expanding a bit: � It would be surprising not to use a flux to help reflow the solder balls
