With oven temps rising due to Lead-Free Processing, I'm looking for some information on high temp Reflow Oven lubricants. I've found some info in the Fine SMTnet Archives on Chain Lubricants, (Mostly Synthetic Motor Oils), but I'm wondering what others are using on their Leadscrews and Thompson Rods? The Biral NMG that we've been using now seems to be binding under the stress of our higher oven temperatures. (It's rated to 265c, but it appears to be drying out.) Any thoughts?? Thanks!!
