RF PCB corrosion prevent coating

[disisku_22]

HI all,

what is the best way to protect RF PCB from the corrosion. any coating should be done to protect, if so pls suggest any method/material. ( RF PCB consists of 2.45GHz transceiver+PA+PCB antenna)

thanks

At low power solder mask is sufficient.

i use spray on conformal coating to seal the soldered connections

Any conformal coating prevents PCB copper from oxidising. Or you may also use varnish ti cover the exposed copper area. Cheers
