Howdy Amol, As far as I can see, there aren't too many pitfalls with SN100C. Just make sure to keep all of your alloys seperated. The issues that I am working out right now is the profiles with our wave pallets and some of our larger components. We

Who is using two sorts of tin in one selective soldering machine with to solder pots? So then the soldering program selects the correct pot (tin). What are the risks? Adding wrong tin in the wrong pot. Mixing up the nozzles?

We're trying a selective soldering pallet for the first time with mixed reviews. Are solder balls a prevalent problem with this process? Most of them seem to correspond with pallet wall locations....is it too much turbulence from the rotary chip wav

I tried some SN100C from AIM... On only one array. It flowed well on the chips but did not like the finish on the SOT23's on the board. I did not have enough arrays to mess around, so we switched it over to SAC305 and had no issues. I'm guessing w

Initial points for investigation are: * What temperatures are you measuring on the leads that do not reflow well? [How does this match with the paste supplier's recommendation?] * Does the component take solder after being dunked in the solder pot? *

Mantis: Kenny reflows paste on [wave solders] all via, not just the test via, to plug the via and provide for a pressure seal between the board and the test fixture. Beyond that, since solder is softer than copper [and fills the hole better], solde

Why are you placing Kapton dots on your board prior to wave soldering? * Prevent solder from touching the hole and the area around it. [If so, why do you need to do this?] * Prevent solder from flowing up through the hole and coating portions of the

We are currently running boards with resistor paks on the solder side of the board introducing these to the wave solder. We cannot get rid of shorting between the leads. We are using a water soluble acohol based flux. The option of going to selective

If you can, attach athermocouple to the locations where you are getting solder balls. A previous product I had showed the same thing and we found that we had inadequate preheat leaving the liquid flux to splatter when it hit the wave. It could aslo

Hello Could somebody inform us about real consumption of lead free solder alloy SN100C on your wave solder process. We do not use some antiaxidant and had had alloy consumption about 1 kg per hour. What is your experiance? All sugestion will be well
