| | hi, | | i am working towards developing a no-clean process for a customer at contract manufacturing facility. the assemblies have gold fingers on them. these are masked to prevent from any damage to them during reflow soldering. the earlier pr

Sure, I'd expect your PCB fab has given you a information sheet on handling, storage, and whatnot, including recommended temporary solder masks. The cats & kitties in the stockroom are the first people to start your search. It's probably squirreled

| Can anyone recommend a solder stop that can be applied by our PCB supplier. Our current material form Tamura Kaken is causing problems. | | The material should be capable of withstanding 1 Surface mount IR reflow cycle and 1 wave solder cycle. | W

| | | My guess would be trapped flux continuing to be active after soldering. Is the tarnish there immediately after exiting the machine? Do you remove the mask and wash right away? If the solder is reflowing under the mask on the component side

Is there a peelable solder mask which can withstand an automated aqueous wash ? I need to prevent water ingress into SMT modules during the wash cycle.

You can use a peelable, rather than a water washable, temporary solder mask? Points are: * Vinyl peelable is preferred over latex, because of lower residues. You should be very concerned about this since you are probably running a low residue proce

If spacing is not to small you could use a temporary peelable mask used in wave soldering. Or have your PCB manufacturer screenprint a peelable mask on for you. These suggestions are only if the mask needs to be removed, If not permanent solder mask

Techspray has a broad line of peelable solder masks. We use the Wondermask P for masking conformal coating as well. Call the company or rep to determine which product is best for you. I am not affiliated with Techspray in any way. If you get tired o

Some questions: Is the peelable/spot masking only being applied to the earthing points on the one side or to both sides? Is the peelable mask you are using specifically designed for coating masking or is it the same as that you use for masking sold
