I am trying to put a center support on a wave solder machine for lead free soldering. My problem is that every metal I use is interacting with the lead-free metals and thus eating away the center support. I have tried titanium, stainless steel. I am

How about graphite coated wires or bar? If there are such things

Sn corrosion effects were studied for stainless steels, coated stainless steels, titanium, cast iron, and other materials. This study can be found in the SMT Library under "Equipment Impacts of Lead-Free Soldering" Electrovert uses a Melonite coating

Try: Tungsten, tungsten carbide, ceramics like boron-nitride or how about pyrex glass? Glass blowers could make "hooks" that connect to a cross bar. I would NOT use aluminum (even if anodized). Try stainless steel 316. 303, 304 do not have enough

We recently added an SPM printer to our SMT department and I need to buy some tooling pins and center supports. Other than MPM, is there any aftermarket support for this machine? Can anyone point me towards any suppliers for the above mentioned parts

Guessing there's no center support in your reflow?

Hoss, that's what we do here. Slotted Durastone bars is all it takes unless the board is big enough to require a center support
