We have some large plated through holes, that we protect with hand placed Kapton dots before they go into the wave. Is there a better option? We are going to see if the boardhouse can put them on for us but I was curious how others are/would do this.

Hi Pr, No idea what the material is - we haven't usd it for a while now, but it was flush & didn't cause any printing problems on double sided reflow. Your board house should know all about it - I would suggest some but ours are all UK or China/Tai

Since these are mounting holes, they're probably all the same size. Why not try rubber plugs shaped like golf tees? Try: * Dempsey Industries; 802 N. 4th St, Miamisburg, Ohio 45342; (937)-866-2345; Gary Pascoe * Shercon somewhere in CA * Harman; 36

Hi, Friends, Could you please recommend me some solder mask materials and equitements for high quality solder mask? Details such as company name, phone numer et al are welcomed. Thanks! Have a good day Xingsheng

We wouldn't advocate extending the soldermask beyond the component body but yes to ganging for fine pitch. To ensure we don't run into issues with flaking our preference is not to add solder mask when the space between pins is less than 6 mil.

This is a question regarding soldermask between pins of fine pitch devices. The majority of our production designs end up with at least 2-3 mils of copper thickness on the external layers due to blind vias, wrap plating requirements, etc. Our curre

If the mask is not cured and is coming off in the pot I don't see how it is protecting anything. If you want to mask something fast you need to use tape not liquid mask that requires cure. My $.02.

Poor training. Don't blame the operator, he was either shown this or left to his own devices. Be the better man and provide him a better process. Regular old peelabale solder mask would be a start.

I recently witnessed a process in which the solder pot operator used Techspray WSOL water soluble masking to cover the areas around a connector that was to be soldered on the solder pot. He did not wait for the WSOL to cure. He soldered immediately.
