Many people may know about circuit boards, but it is estimated that few people know about their maintenance. In the daily operation of the electronics industry, it is often encountered. Kind reminder: The circuit board should be regularly maintained during use to ensure that it is in good condition and reduce the failure rate of the circuit board. The following points are useful, be sure to bookmark and share them today.
First, six-month maintenance:
  1. Clean the dust on the circuit board every quarter using circuit board specific cleaning solution. After cleaning the dust on the circuit board, use a hair dryer to dry the circuit board.

  2. Observe whether there are high-temperature traces on the electronic components in the circuit and whether there are leaks in the electrolytic capacitors. If so, replace them.
Looking at annual maintenance again:
  1. Clean the dust on the circuit board.
  2. Conduct a sampling inspection on the capacity of electrolytic capacitors in thecircuit board. If the capacity of the electrolytic capacitor is found to be less than 20% of the nominal capacity, it should be replaced. Generally speaking, the service life of electrolytic capacitors should be replaced around 10 years to ensure the performance of the circuit board.

  3. For high-power devices coated with thermal grease, it should be checked whether the thermal grease is dry and solid. For dry solids, the heat dissipation silicone grease should be removed and new heat dissipation silicone grease should be applied to prevent high-power devices in the circuit board from burning out due to poor heat dissipation.
Because circuit boards are mainly made of solder pads Through holes Installation hole wireway. components and parts. Connectors fill. Electrical boundary circuit board industrial zone and other components. Therefore, during the maintenance process, it is necessary to observe the inspection and unified investigation of these components in order to identify problems and carry out maintenance work effectively.
