Need more information. BUT if your strictly considering just the paste change. I would imagine your changeover would be little to no different than changing to the second board if you were using the same paste. Maybe take extra care cleaning your sq

When I said partial build I should have clarified that all the boards we build are double sided so the plan is to build the bottom side then build the top side as they are ordered. The bottom will be standard and the top will have the options. I di

We are planning on installing an SMT Line in our building. We own 75% of the building, there is a crossfit gym next door and they tend to drop weights where we can feel the vibration. Should we be concerned with the SMT Line being set up on that end

Relying on AOI for sensor boards - EOL for functional test

Depends on what sort of outfit you are working for, and what you are building. A lot of CEMs are doing Flying Probe or ICT on the boards ahead of investing time building into units or adding parts that prevent access to rework. We have a combination

Run a water-soluble mask that foams in the wash. Use a de-foamer to contol that. One or the other, or both are causing a greasy build-up that is hard to get off in certain areas. I have a closed loop DI water system. Can I use some sort of deterg
