How should I handle wet PCBs?

A batch of PCB got wet in warehouse due to roof linking. Too terrible to shoulder the lost. How can I do to rescue these wet PCBs? Or to minimize the damage?
  • The best solution is to dry it by wind and then sunshine.
  • Clean PCBs with high-purity alcohol if available. High-purity alcohol can dilute water and promote ventilation.
  • Test them before using in case of any residual water.

Anyway, the stability of the PCB is impossible to recover as before, but they can work. Ten slotte, they have been damped. If they pass a wet test before selling, things will be better.

How can I mount a pulse oximeter on the surface of PCB without putting too much stress?

The PCB has a pulse oximeter mounted on the surface, and it’s tolerance is 0.6mm. The problem is the pulse oximeter needs to touch the bottom case at all times. How to best mount the PCB in the case without putting too much stress on the pulse oximeter? Will screws with flexible washers be all right? Sadly separating pulse oximeter from main PCB is not an option.
