I have been using sn100c for over a year now on our wave solder process and I am plenty satisfied so far. The secret for success with this alloy is to have your solder pot near 270 celsius and your dwell time has to be near 4 sec and your temperature

I have done a few studies on this issue here. As a result we have increased hole diameter on heavily ground planed pins to a min of .015" over the lead diameter as well as preheating the PCB when hand soldering. I have also had to order the upper pre

First, Your flux is no good replace it. second, Check for pre- oxides. The smaller the component or the leads makes it difficult to solder specially if it has oxide. Thrid, check the board to wave parallelism. Maybe your wave is not parallel to the b

Hi all, I have an Electrovert Econopak Plus wave solder machine. Lately the solder pot temp has been fluctuating +/-10 degrees c. I have replaced the thermocouple as I suspected it to be faulty but the problem still exists. I am confident that the

All, I am currently trying to run a quantity of boards thru my wave machine but I am having serious issues with hole-fill or lack of aswell as others. The boards are HASL finish and due to materials issue they have been waiting for Wave Solder Proce

Hi all, A quick question to see if anyone can solve my issue. We are having problems with a particular board we run through our wave solder on a pallet. The board is populated with about 20 fuse clips, and one clip on almost every board gets fille

| We are a medium sized PCB assy. house manufacturing about 2000 motherboards a day. There is a major problem we are facing at the wave soldering stage, i.e. warpage of the PCB. As soon as the PCB touches the wave it warps severely from the centre
