Set-down height to low, iow, parts getting squashed too deeply into the paste. No mask between pads on fine pitch. Pads too wide for the pitch.

This recipe is nice for leaded soldering. The time above liquidous plus 20*C is too short for mixed alloy soldering. Remember all that nonleaded stuff that you add to the solder acts to increase the liquidous temperature of the alloy. Try slowing

Have you tried doing a short diagnostic test? That will check the repeatability and backlash of the axis. Did you use the C-tool when calibrating the camera?

If you have surface mount on the bottom, you can place openings between any thru-hole parts that constantly short. Your adhesive is a natural solder block!

orientation is also a factor here, So what is the pitch of these connectors? the lead length? the hole dimensions? surface finish? and what type of wave and flux are you running? Shorts are pretty easy to eliminate if everything is of adequate des

Hi, I think our Splice Device is the tool yiu are looking for. It can be used in high volume production for splicing in the production line OR used to splice short lenghts of carriers to a complete reel. http://www.dekitools.com/group.asp?group=664⊂

Maybe, but distance between Tantalum capacitor and BGA is about 1cm. Also how evaporation can affect on the BGA balls and can be cause of short?
