James, if you want to get a circuit board wet, then any cleaner will do. Tighter componentry and BGAs are different. Even if you submerge a BGA, the surface underneath it will not be effected. Thus you need to force the chemistry mechanically unde

That's cool that you used the Archive. Consider running a designed experiment on your board, using your flux and solder, the limits from the Archive, and on your machine to dial in the spread in dwell numbers you see in the SMTnet Archives to your s

We are using Austin American Technologies with Petroferm solutions and have excellent results using the same two types of solvents for cleaning stencils, adhesives and miss print boards. I average about five hundred cleaning cycles before we have the

Mark - The Waverider is a great tool. It will let you know what's going on with the machine itself - contact time in the wave, parallelism of the wave, temp, and a relative idea of whats happening in the preheat section, and conveyor speed. We hav

You need to contact several different providers of alternative solutions. Ask them what current fair market value for your equipment would be if it were sold to an end user (customer). You will definitely receive a higher ROI from an end user than a
