Hi, I am experience problems while testing wave soldering SMT components that are glued on the solderside (lead free). Between de leads of SOx type IC's and SOT's develop a great deal of solder beads. I have been using a RSS temp.profile while spr

Hi everybody, We have wave solder fixtures made of Durapol and multiple wave solder machines. Most likely we�ll use the same pallets for either tin-lead or lead-free solder for a while (of course after washing the pallets). Should we test the palle

I don't think that you would need to test these. Have you ever seen any evidence of solder sticking to them? We use the same material and never notice anything besides flux staying on the bottom. Would the lead absorption if any even be of a concer

Ideal situation is get a technical rep from the solder paste supplier. They know their paste better, and should be able to work out a profile based on their paste and your oven. Again, a technical rep, not the sales guy.

Do you have a Slim-Kic? You can run a profile and then do predictions from there. Very useful tool.

Some profiles can be difficult to get exactly, so I was wondering what effect a slight deviation might have.

Time and temp in lead and lead-free reflow

my oven has a built in profiler, it works fairly well, but it can not predict changes. my main concern was about the time right before reflow. i know that's where the flux is activated and i was worried that i may be spending too much time at the tem
