| I finally got my problem figured out on the bridging, the | only thing I'm finding is that I notice some litlte solder balls on the bottom of the board. Is that normal? Is that why I'm getting bridges? Has anyone came across this problem and pass t

The soldering handbook that I use gives a 'rule of thumb' for best preheat temps for wave soldering. For multilayer brds that are metal core it suggests 110 to 130 degrees C topside temp to get the best solder fillet. We do a lot of multilayer meta

| I am experiencing a wave-soldering problem with a leaded capacitor - too much solder above the board!! The capacitor lead is .020" dia. and the hole size is .038". This only occurs on the negative lead of the component. The capacitor is also axi

Hi all, been recently wave soldering some pcbs with no problems and have now noticed what looks like blue residues on some solder joints. We have been running this product for around six months and this is the first time we have seen this. It is rand

is there any standard gap between the terminal and pad if we place the glue? SMT-4 mention as per what you understand which is using glue at SMT without solder paste and run at wave solder for the solder paste at the terminal. Glue supplier recomm

How are these connectors and dips oriented? If the leads are parallel as opposed to perpendicular to to the wave this can promote bridging depending on spacing and length. The long leads showing icicling are most likely either inadequate heat OR the

You're a piece of work! Why don't you work for any of the major wave companies? So how does slowing the conveyor speed eliminate drying flux? And when you slow it down, what speeds it up to make you say "I lower the wave because I get shorts going

Found problem many years ago by chemical extraction and IR analysis, produces alarming amounts of plasticizer from under cured or incorrect mix of hardener to liquid photoimageable solder resist. Problems this causes are endless and many things blame
