I am currently working on a manufacturing flow where some PCBA are processed with reflow oven (after being baked before processing), then cleaned with bath, then passed into contaminometer, passed into AOI. The point is after all of this, if AOI dete

Hi all, Can any one suggests that is there any method to remove BGA from a PCB without applying heat..??? Like any chemicals which can remove solder from both BGA & PCB without creating damages - Because customer feels heat application may erase the

Try adipic acid to clean your nozzles. It is a powder and can be awkward to work with as a result. But you might end up preferring it. Also look where the substance is not. There are two PTH joints without it. And that chip cap is closer to the PT

@charliem, For the clean process board using "water-soluble" fluxes, we will send the board to aqueous wash with DI water first if not able to manage to proceed with the second process within 24hours. Then, keep the board under room temper

"Must Have" is when it becomes a requirement from a customer. It is utterly impossible to inspect every solder deposit by eye on any board layout that is even moderately busy. I have lived without SPI and then implemented it across multiple lines. I

Try adding blow after mount before head up if your machine lets you. Make sure your placing the part into the solder paste as that will add some holding force as well. If your tips are spring loaded you can do some 0.5mm additional mounting height.

I got your email and responded a few times. I asked you another question via email, but you can ignore it if you find it because I managed to figure it out. I really can't thank you enough, I never would have figured out the calibration issue witho

Low Temp solder and a cooler profile should certainly help. I do believe that the unbalanced copper is the culprit, but you could try to prebake some boards. To eliminate some kind of manufacturing defect from the equation. Though I'm pretty sure i

Just because you can't add copper to the board, doesn't mean you can't add copper to the panel. Redesign panel, where board house can add copper to the panel to balance the board a little better. I would advise against low melting solder alloys on cu

I would certainly test the boards but from our experience, the vacuum sealed in room temp, no issues at all with our PCBs sourced from Suntak / PCB Founder / Fastprint / Yaxinda / JLCPCB well past the 12 month mark. We building boards purchased 5-10
