Custom printed circuit boards are based on insulation board, it is an important electronic components, electronic components can be achieved between the connection.

Application of high quality PCB is more extensive, maintenance of PCB can prolong service life.

1, clean the dust on the fast PCB prototype.

2, the PCB in the electrolytic capacitor capacity sampling should be replaced in a timely manner to ensure that the performance of the PCB circuit board.

3, for the high power device is coated with thermal grease, should check the thermal grease not dry. Prevent large power devices in the circuit boards because of bad heat and burn.
