As a professional fast prototype PCB manufacturer, we will share some tips on maintaining pcb:

six months maintenance:

Observe the electronic components in the circuit have no traces of high temperature, electrolytic capacitors are not up to leakage phenomenon, such as the need for replacement.

Every quarter of the PCB prototype on the circuit board of dust cleaning, special cleaning fluid available PCB circuit board cleaning PCB circuit board dust after cleaning, use the hair dryer PCB circuit board blowdry.
