Dear Net member,

     We have a hybrid PCB with microBGA and some resistors/capacitors. It
     is a through hole component for data transmitting. When the customer
     insert the component to a PCB and finish the wave soldering.  It is
     necessary to clean the board. Due to its application in high
     frequency, the residue of water after cleaning will cause short of the
     circuit.

     To solve the problem, we like to try the conformal coating the PCB. Do
     anyone can recommend the conformal material and the process?
