Hi Everyone

What lubricants do your maintenance people use for the chains in your Reflow ovens?

The manuals for our ovens have one recommendation - but I am always open to other people's experiences and recommendations. Another option may be easier to obtain locally.

I have identified one particular locally available option -but in comes in a minimum of 20l containers - enough for years given our requirements.

Has any one had any concerns regarding outgassing / contamination from chain lubricants exposed to reflow temperatures?

Any experience with problems caused by oil contaminants? (Obviously excluding extreme excess lubrication getting on PCA's, killing flux activity and causing solderability problems.)

What I am referring to is contaminants such as carbon or sulphur vapours from the degradation of the lubricant.

What components should be avoided when choosing a lubricant to be used near SMT assemblies?

E.G. If you look at the silicone situation of using neutral cure instead of Acetic acid cure based options.

Thanks in advance for any help you can provide.
