Reflow and wave flow solders have to be changed more often because of contamination. Pb free PCB's don't solder as well so you will likely have to find a new process or supplier. The higher temperatures heat soak the components so they all need to be

Hi I came across this article while writing a paper. I don't know if it's the first, but it is early wave soldering: W L Oates, "Automatic Soldering Machines for Printed Circuit Board Assemblies", IRE National Convesntion Record, Vol. 6, No. 6, pa

| I am running composite fixtures on my wave solder machine and after about 500 passes each (1 month)they are showing serious signs of wear in that the composite surface is bubbling up and glass fibers are also starting to show. | The problem here

| Howdy, | Is anyone using Seho? Need to know more about 7000 series machines with nitrogen and ultrasonic fluxer capabilities. Any shortcomings (I can't see them)? What are the positives, beside those obvious? | Earl Moon I have a 7240n2-F. I have

Dason, IPC/EIA J-STD-001C states: "....temperature within the range of 230C (446F) to 290C (554C)." That's a pretty wide process range. 250C has been typical in the past. We run ours from 230C to 240C. We have found that some single-sided PCBs can de

Hi, I've got a Microline 200TF - I guess it's a 1980's machine. It's gone pop and I cant fix it without a circuit diagram (there's several pcbs in it with a variety of relays, triacs and what-not). If anybody has a circuit or any othe rinfo on it I

Having an issue with tracking for the Vitronics Soltec Delta 3. Wave will not give error on "expected PCB at exit" but will still show 1+ pcb's in the wave when the machine is empty. This is causing solder pump to idle unnecessarily. Outfeed sensor i

I understand your need for more wave solder imput. It seems to me that every year the pwb's that I am given for solder wave are thicker and have more ground planes. There have been times I have asked questions on SMTnet about pwb's received in hous
