Yes, I have tested some boards, and found that most QFPs which near the via will have the higher temperature. One of my customer requirement is to have the temp less than 200 deg C for top side. We were using the hi temp wire to solder the QFP's for

Patrick...I'll give you a couple of examples. Wave Soldering, the Science: you're getting solder shorts and you slow your belt speed down just a bit knowing that this effectively lowers your contact length and improves your peel-back for that tou

I have CCA that has a SN100C HASL coating that I am wave soldering with SbPb. I have mounting pad areas on the CCA that are masked with a pallet during reflow so they are not exposed to the solder. The mounting pads are turning gray in some areas of

first I am personally not a fan of dross reducers. We have enough issues with contaminants on boards (high impedance analog) so i do not want to introduce more contaminants into the process. Second I have not had much luck with any dross reducers. We

Maybe this piece of information will help. In China (just returned from visit) there are many factories that are using a dual temperature process using SAC305 or Sn100C and 42/58. Apparently this allows them to run their through hole parts through re

Make sure you are providing an adequate moisture bake out prior to wave soldering. It sounds moisture related since is so random. I would suggest perhaps 120C for a minimum of 8 hours to drive the moisture out, and then complete your wave soldering

I'm not a Wave soldering guy and my friend have asked me a question on what is the best preheat time and temperature for Wave soldering.They experiences only 10% flow up thru the PTH barrel. I've asked them to increase the temperatue to 120 Deg C. Cu
