| We are an assembly house engaged in large volume manufacturing of Computer motherboards and others. We are in the process of selection of a new wave soldering machine. Can somebody help me inform what are the different parameters which must be ens

a) Is there a recommended dip or dwell time for the dip soldering? Check your data sheet for the part. Dwell time is everything in selective soldering. Top side wetting is a good process indicator. b) How do we improve the solder coverage in the

We haven't run a profile yet....probably because we're a-feared to. We can't do topside preheating here to any degree because we use an aluminum plate for aligning hundreds of top side through-hole components (pots, switches, buttons, LEDs) that te

Hi, I have a Fisnar I&J500 Selective soldering robot that has failed. I think it is from around 2000. The Fisnar I&J500 base has a soldering attachment on it. As I understand it, the base controller sends it a 5 bit command to the soldering unit. T

Steve, I wave solder most if not all our boards with selective wave pallets. I did not catch if the solder balls were on top of the board or on the bottom but that will make a difference on what to do to get rid of them. Pallets are good and bad. On

I may be stupid but what exactly do you mean by "foil" on both sides? Are you having trouble with top flow? bridging? Are you using water soluble or noclean? Are you also waving SMT components? Anyway, normally the solder temp should be 460 - 500 F(

At the price of Durapol we'd never get the OK to have them made. The Al fixtures are cheap and a quick turn local item. As dense as the pth parts are I also don't think there'd be any room for any holes which I really think is the answer as far a
