Successful solder paste overprint is a function of the solder paste rheology, solder mask and through hole component stand off. * Solder mask with a high surface energy will permit a larger overprint than a solder mask with a lower surface energy. In

One thing you could check/monitor is the temperature in the pot/wave. As boards run across the wave, they will cause fluctuations in the wave temperature. The heaters should hep with minimizing this; but, if you're running a lot of boards in quick

Hello, in Europe (SN100C sold by Balver Zinn) several solder pots have been filled by this alloy. On the paper I heard talking very well in terms of performance and good price, but not data are available ( as I know) about performance and if r

A little confusion here. Are you running several boards in one pallet and the last boards are looking poor or is the issue getting worse as the day progresses (like as the pallets get warm)? - If it is the last boards in the pallet, then you may wan

Armando, Is the problem in the same spot on the board with every run? If so, there might be something about that particular location that is part of the cause (ie. ground or power plane connection). It sounds like you're seeing blow holes, or insu

Hello Carl, The main reason there is little information on lead free soldering to ENIG is because most of the lead free soldering to date has been Japanese consumer products. To keep costs down, the major surface coating used has been OSP copper. It
