We (ETS) are a manufacturer of reflow, curing and preheat systems and have had similar requests from customers in the past. One in particular required soldering onto an aluminum heat sink weighing approx 5 lbs. You might consider selective/robotic so

For what you have right now I would recommend that you use soldering iron tips that are made for component removal. until you get BGAs I wouldn't worry a whole lot about the expensive rework equipment. I would use specialty tips and a heat gun wit

Evtimov, thanks for your reply. Yesterday was our first day of running 99.999%. We were running for weeks with 99.99% Nitrogen purity and we just were having all kinds of problems with the miniwave not being consistent. We had a wave offsets at 75,

Kurtz had a guy that was great with the machine. I strongly suggest that you watch the wave height test a few times in the morning then at lunch and at the end of the day. Look where the solder goes up to on the probe. If it doesn't work consistent

Mainly for ERSA machines, but I welcome other machines info also. What are you guys getting in regard to nozzle life? I am running an ERSA 3/45 with 4 solder pots in it. 2 lead solder and 2 leadfree. I'm very pleased with the nozzle life I'm gettin

Robot soldering has never really worked well and if you are looking for any volume or repeatability, you may be disappointed! Even though you are using a robot, you are still soldering with an iron and wire solder. This process cant guaranty the be

Hi John, We have been selective soldering for about two years. My suggestion is to use the same guidelines for preheat, duration and temp as you would in wave. Your flux manufacturer should be able to provide you with the details. Good Luck Chris

It realy depends on your product. Tighter tollerance boards require a better machine, which costs more money. Multi-layered baords wih a alot of heat sink will require preheat - something a lot of selective solder machine do not come standard with.

To get out of a delivery pinch, I had to pre-tim some connectors because of contaminated leads. Make sure your selective wave speed and XYZ travel are close. Try doing a dry run across the board to preheat the PTH and then go back and solder them.
