It's a BGA component. Missing ball is not possible because we have enabled the vision in pick and place. Solder paste is OM353 type 5 Possibilities of Flux dry before reflow seems valid but I saw the board data it was completed on time like other

Based on datasheet you can have balls with significant variation(twice volume) 0.13Sqr/0.19sqr = 0.46 I would suggest you tighten the machine recognition control. You will recognize BGA balls that are very different in size and reject the part. This

Snap off is an option to make distance between PCB and stencil. If the distance not enought, adjust the PCB thickness too. Mostly we don't use snap off, I more prefer if the stencil is tight with the PCB - I know, this make the stencil lifetime worst

Hi Chris, Thank you for your advise. We got problem on key in parameters. Why we can't save value on parameter after key in manually? When we key in Parameter, we used password 9060. Is there any other password to key in and save machine parameter? T

I don't know about potted PCBs, you'd have to talk to the recycle. My guess is it doesn't matter, worse case they just pay you a little less per weight so you'd just keep the potted PCBs separate from the rest of the waste.

I think jurisdiction will make a big difference with respect to exact details. I would think for example that WEEEEEEEE in Europe would have a lot to say on the subject. And there would be several local governments with their own special regulations.

When I was a kid, my mom liked to read The Little Prince for me and now I still like the little prince and his rose， so I made a flower with LED PCB for my kids, and the rose will never fade on the happy earth. In addition, I order my LED PCB in pcbg

Also yes I know about Mirtec's second owner program but it is not an option considering the cost of that is almost as much as it cost to buy the machine. Does anyone have like a developer manual that gives in depth explanation of the functions/tools

I was told by Mirtec I could not get any manuals without buying the second owner support. I have a simple manual that goes over making a program, creating parts. That manual covers using the Mount inspect, IC inspect, Chip inspect tools but nothing

I need a Sanyo Denki 103H7570-7024 stepper motor to repair a Quad QSA-30A machine. Some idiot put a 2-phase motor in there! It is supposed to be a 5-phase motor. If anybody knows where to get these, please let me know. Apparently, the same motor
