solder balls on pcb

Electronics Forum | Tue Nov 04 12:58:17 EST 2008 | smt123

I have to agree with Patrick here. This image appears to show a board that is NOT HASL as there is what appears to be a copper pad in the upper portion of the image. But then again the arrow tip appears to be white and I woudl expect that to be red s

Thanks for your replies! So what I understand is that ICT in reality is "only" a production process safety net, but it's a net that in most practical cases is needed. What ICT can not catch is (all) bad solder joints. What are the methods to find t

Mikej, I'm only running a single image, just want to correct for the slight variations in how the board seats in the transport. It's not more than a few mils off, but enough to cause an issue on fine pitch parts. I don't have any image fiducial

Not true... with manual screen load machines (LT / Horizon), you need to ascertain the correct position / measurement and can load to that position. Auto load machines there is a "custom screen" setting which is used to tell machine the position ("Di

I did not see the histogram image (didn't scroll down). My point about the flat metal surfaces is they should have a large white total under top-light with red filter. You should be able to distinguish between the two (fillets and no fillets). I k

It should be possible to use Ghost to copy the Harddisk nut installing it in another machine. The next trick is to repair the image by cutting the missing bit from another image made on a Virtual Machine. Be careful to use the same version that was o
