Waves soldering: not enough solder remaining on pads

Electronics Forum | Mon May 22 17:54:46 EDT 2017 | zsoden

Thanks for the replies. The single missed lead is a bit odd - we usually have an entire area missed and that's due to the board not sitting properly in the pallet fingers. I figured in this case it was likely due to poor fluxing? We have always str

Hi all, Our Fuji cp6 woke up with a bad power supply (ps) this morning. The ps is one of two 24vdc (Corsel P300E-24). There is one inside the cabinet and one on the door where the cpu card is. The bad one is the one inside the cabinet. So we had anot

Component Database and Placement List

For package shapes/names I would recommend using manufacturer names. This is much safer than coming up with descriptive names like QFN32_5x5 as there are multiple 5mm 32Pin QFN shapes even when pitch is the same, this makes it safer to use a name in

JUKI vs UIC Pick N Place Machines

I'd be tempted to say you buy whatever is most consistent with what you paid for the rest of the machine.... And if you can source Chinese copies& they aren't expensive it can't hurt to try a few. More generally (I don't know how these particluar ma

Topaz X error

A Table is something that you can ignore right now. It is significant only in case of dual table machines such as Sapphire or Sapphire-X which have A and B tables (two independent PCBs being handled at the same time). In case of Topaz or Topaz X or E
