I am sure you can reflow lead free in any oven but i thought i read that lead free requires a cooling stage to get the solder joints reflowed "correctly".

The holes on the circuit board which need to be covered are very small and it is more time consuming to cut to size and place with kapton tape. Thanks for the feedback.

For dots this size I have applied a thin coat of Chemtronics CM8, let set 10 mins then waved. The preheaters finished the cure before the board reached the wave. You just have to drill into the heads of who applies the mask that thinner is better!

Consider: * Changing your temporary solder resist [TSR] to a light cure. * Contracting with your board fabricator to apply the TSR. * Gaining better thickness control of your application process by silk screening the current TSR. * Forcing more air c

One of my co-workers told me he worked at a place that used a UV cure mask. They screen printed the mask then UV cured it. Then they assembled the baords. He doesn't remember the brand of the mask.

Amejia, If your application is strictly conformal coating and no heat is applied to the board, the product seal and peel would be the solution see link http://www.interfluxusa.com/misc.html This product solidifies immediately on cooling The only dra
