Hi Tech Net,

In the near future we will start flow production of flex-rigid boards. The
boards are going to be double-sided smt so we will have two runs on our
production line. We use an oven for storage with a temperature of 30?C. I
have read that we should prebake the boards at 130?C four hours before
production.

Since this is a double-sided board I would like to know if there are there
any requirements for storage between the two runs.

Can anyone share his or her experience on the subject?

Thanks in advance.

Hilbrand
