Well, inquiring minds want to know how that machine got in that condition? Left out in the rain for a year? Fire sprinklers went off? I almost believe it DID get dunked in the ocean, the corrosion is pretty awesome! Jon

What steps are taken in low residue wave soldering to assure the proper amount of flux is applied prior to soldering? * Too little flux can result in poor solder flow. * Too much flux can result in corrosive residues left on the board after soldering

physically lift board of after fluxing to visually see what is covered, or using thermal fax paper to get to see coverage works well. PROPER low residue or no residue fluxes leave benign insulating residue behind not corrosive.

Try Zestron Vigon RC 101. This mixes with tap water. Electrovert does not recommend DI water due to its corrosive nature. http://www.zestron.com/fileadmin/zestron/overviews-tis/usa/ti/ti-vigon-rc101-usa.pdf

To close the issue: PCB Fab had a look on the PCB's then decided to recall them back...including PCB's that's already been built... cheers!

Quick production (no "pasty" phase) > High joint surface quality > Good flux action > No discolored, corrosive, or substantive residue of any kind > Lead-free is not a concern ;o) Any input/ideas are appreciated. Thanks!

Sure, it will work. It probably will be better than what you're doing now. Consider disconnecting the heater. It not a good choice, if you use DI water, because of the corrosiveness of the water on the plumbing of the washer. We talked about this pr

The solder wire uses a ORL0 flux. The wire contains less flux at around 2.0-4.0%.

That will definately cause a shorter tip life. The high tin in the alloy along with the higher temps are probably your culprit. We have noticed a degredation it tip life when we changed from leaded to RoHS on standard PCB's. Good Luck Chris

They could be correct about the silver if it weren't such a small portion of the connection. Study "electrochemical series of metals" to understand how metals react with each other.
