Sorry on N2 and tombstone, many other aspects cause tombstones and n2 in itself does not cause tombstones. It can help make other bad variables tip over edge to cause tombstones more than with no N2. Get these right then N2 is not issue.

Are you stuck with pin transfer for some reason? Screen printing is more repeatable and easier to maintain.

We are looking for a new machine to replace our Asymtek C-708 that we use for wave masking. Asymtek offers a D-585 but we were looking for something better then a table top unit. Any recommendations on a company or machine? Thanks

This is not what we'd expect. We need more information about process, materials, and distribution of the problem. Also, a picture would be nice.

If this is a water soluble flux, then the discoloring is caused by the still active flux microetching the solder fillets. Prevention is to wash off all water soluble flux as soon as possible
