WebFeb 7, 2024 · Reducing Outgassing. Rush PCB bakes their PCBs to remove moisture. Water absorbed by boards can vaporize and release gases during solder reflow causing different types of defects. In space applications, the same vapor or moisture can outgas in the void of space. Baking the PCB in vacuum ensures residual moisture reduces to a minimum. WebTraveling Wave Tube.
