Just my opinion but it look's like your doing a great job. i would try another paste. I'm somewhat lucky that we get to use OA's. If your stuck using the no-cleans they are so tempermental. (The nitrogen is making up for the poor paste) Your de-wetti

There must be discussions about this on SMTnet but I have yet to find them. I would like to hear from all you smart people about running LF and PB BGA�s on the same board using 63/37 solder. If you run your profile up to peak at around 225C +/- (nitr

Are you using nitrogen with your wave? You probably will need to with selective. With our Ersa we need 99.9% pure nitrogen to make it acceptable. They spec 99.999% which means liquid nitrogen. We tried one board without nitrogen, it left a two in

We have an ERSA Versaflow Ecoselect selective wave soldering machine. It works well except it needs nitrogen. You can't even move the table around if your nitrogen tank is empty. The spec sheet says Required degree of purity: Nitrogen liquid 5.0

We have an Ersa Powerflow N2. It's a very well built machine with excellent support. We run it (2) 10 hr shifts per day, 4 days a week. Having the full nitrogen tunnel has greatly reduced dross and improved hole fill. This replaced an Electrovert Vec

We aquired an ERSA ECOSELECT 2 selective soldering machine. So we are going through a learning curve and I would like to hear from ERSA users on this subject. The main concern is to keep the miniwave steady, it seems that it " bounces" a lot and is
