Sn63Pb37 on RoHS compliant PWB

Electronics Forum | Thu Apr 12 17:34:05 EDT 2007 | carsan

We are running RoHS compliant & non RoHS compliant assemblies. We buy our bare boards from one supplier that only manufactures RoHS compliant boards using a Sn100 finish. Is there any known issues running leaded solder on a Tin finish? Does normal

Minimum lead pitch to avoid bridging

Electronics Forum | Thu Jul 05 08:11:45 EDT 2007 | naynayno

This is wave soldering process and design question since most folks associated with SMT are processing mixed assemblies. We have a 3-leaded sensor (radial) with such a tight pitch always bridges. Solutions unders disussion are pre-forming and addin

Hi BR, Are you screen printing adhesive to the bottom of the board? If so, have your stencil make put openings between the leads of the thru-hole part. SMT adhesive acts as a natural solder resist. So placing a small sliver between the pads works

You probably could SMT it (standard Process)first, do your PTH and then wave solder using selective solder pallets. If you stick with your current method I would consider a mini stencil such as the ones used for BGA replacement to apply paste. This w

We use copper grease on the bolts of our wave solder machines solder pot. The working temperature is up to 1000degC. I believe that the boiling point of mineral oil is a little over 300degC and you will exceed this with iron temperatures, especially

Yes, i'm agree with you davef but i'm not put the chipbonders onto pads. i'm put the chipbonders at the beneath component (center between both component terminals) which the idea is to hold the component during wave soldering which might cause the co

Steps to Convert SAC305 Wave Solder Pot to SN100C

Ask FELDER (gmbh), they can replace the alloy (SN100 +Ge+Ni ...) or even with a special kit (FUJI Patent) or if preferred you can transform the solder in the pot w/out replace it in a reliable way. http://www.felder.de/en_produkte.phtml Regards...

We exclusively use a printer to do glue these days but keep in mind there are times when glue and paste work best. Things like poor layout (ie shadowing) or tall parts that may shadow themselves or a wave solder machine that is not particularly good

Barrel fill with Pb Free Wave Solder

Electronics Forum | Wed Dec 10 00:15:07 EST 2008 | jeffjarmato

Are there any good solutions for getting good barrel fill on PTH boards using Pb Free solder and No Clean flux. All of our boards are having issues getting minimum required fill per IPC. It does not matter if the board is 062 or thicker, any pin conn

Questions are: * What kind of oil is this? Where did it come from? * In olden days, we used to pour oil on the wave solder pot to limit dross formation and loosen-up the solder. Miss that stuff, sigh. * Is there oil under the BGA? It's surface ten
