Id say get them panelized to help lock it down in a basket or under a screen, we actually started making our own baskets out of screen material, tight mesh and not as rough. the other option would be to get something to hold them off the wash conv ho

Panelization is the way to go. Once it is panelized you can get them in a panel the options open up. Custom wash fixturing would be the way I would go if you have a tooling budget. The guys at Pentagon EMS have always been able to put together some n

I have nothing to add technically but we have been washing no-clean for years. Use very clean filtered DI water to avoid the white residue issue and some good detergent or sopanifier and you will get great results.

We have passed testing using this process, I would consider it on a case by case basis however. We are very careful about the quantity of the O.A. that we use. The water soluble flux is gone after cleaning unless it was/could be encapsulated or tra
