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.

What are some of the benefits and downsides of moving from a two layer PCB with components on a single side, to a four layer PCB with components on both sides?

We got a quotation sheet of four layers board but it greatly exceed our budget. So now we are thinking about reduce layers to save cost. Does this solution work?

What should be the size of an NFC antenna given an operating distance?

I am dealing with a project about a PCB with NFC antenna. We are designing PCB now. Do anyone know about the size of an NFC antenna if we want it operate in 10 centimeters?

On which layers of four should the trace antenna be (433mhz)

Our team plan to launch a GPS device for food safety tracking, with a four layers PCB inside. Where should we locate the antenna?
