PCB adhesive is an excellent option to connect circuit boards to other surfaces. Like all things it is a tool that can be used for good or bad. If you are applying it properly, PCB adhesive can help in sealing the connections between the circuit boards and the substrate. However, if you are not careful, PCB adhesive can also leave residue of adhesive on the surface. This could result in a difficult to remove the circuit board. To avoid this, be sure that you apply PCB adhesive with the correct strength and use a clean, dry surface.
