Hi, I am a new guy for this field

There is one problem bother us for a long time. I am an engineer who is in charge of SMT. Before SMT assembly, we have to check the moisture status on PCB. My problem is what level can be accepted for the relative humidity on PCB before mounting component. Could any body have your kindly suggestion ? Tks.
