| I have gold fingers that I want to mask when running over the wave without pallets. They're on the leading edge of the board. I recall seeing rubber boots that slid onto the fingers to mask them. Pop 'em on before the wave; pop' em off after and

Hi, Need your help. Easy one. How do you evaluate Spot-on Mask, those that are peelable and used for wave soldering and conformal coating? thanks and regards,

We are planning on converting to a no-clean soldering chemistry and will need to replace our water soluble liquid solder mask as a result. Does anyone know of a dispensable, "peelable" solder mask I can evaluate? It would be nice to find one that i

Has anyone experienced bridging on topside (solder destination side) surface mount devices after wave soldering? We x-rayed 100% of the placements after smt re-flow with no issues. When the same placements were x-rayed after the tht wave solder pro

It all depends on process, design and environment in which the contacts are used. Both have excellent conductivity characteristics Both don't oxidize over time On the other hand gold is much softer then carbon, and after hitting that contact a gazil

Peelable masking has been our solution here recently. We an automovite customer that requires coating on both sides of the boards with many keep out areas. We are currently building a dispense robot that will apply tech spray wondermask 2218. The won

| | | 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
