Hi Forum.

Is there anyone who can tell if an empty PCB with no SMD components mounted and HAL surface will get a less solderability after been running through reflow (convection).

Eg. when testing empty PCB with temperture data logger.

Regards Ole

Excessive baking can actually lead to oxidation and create solderability issues. Why would you profile with empty board? But even if you do that, better use solder sample board.

Hi Evtimov Thank you for a quick reply for my question :-)

The reason why I am using an empty board is only to have a place for the temperture logger beside the fully mounted SMD board that is monitoring the reflow-profil and also to get the same conveyor with through the rewlow.

However this is not the best way to do it.
