with the development of electronic technology, circuit boards are widely used in various fields, almost all electronic devices have circuit boards. High-end automotive, aviation, medical electronics, common smart home, communication electronics, household appliances, etc. pcb board as a carrier of various types of electronic components, play the effectiveness of different components, the following NeoDen to tell you about pcb board storage temperature and humidity and how to store.
PCB board storage temperature and humidity
PCB board production steps, and the requirements are in the clean room operation, so the manufacture of pcb on the environment and temperature and humidity requirements are relatively strict. Temperature and humidity is not appropriate, it will lead to pcb board corrosion, reduce the life of the circuit and reduce the performance of the board. Therefore pcb board should be kept in a storage environment of temperature: 22-27 degrees, humidity: 50-60%.
PCB board how to store and storage time
1. PCB production and processing, should be the first time to use vacuum packaging, and vacuum packaging bag should have desiccant and tight packaging, can not contact with water and air, to avoid pcb circuit board surface spray tin and pad bit is oxidation affect the welding and product quality.
2. PCB boards should be sorted and labeled, sealed boxes should be separated from the wall, should not be exposed to sunlight environment, to maintain in a ventilated and dry storage cabinet with a good storage environment (temperature: 22-27 degrees, humidity: 50-60%).
3. Long time not used pcb circuit board, the best in the period of the surface brush three anti-varnish, moisture-proof, dust-proof, anti-oxidation, so pcb circuit board storage life can be increased to 9 months.
4. Unpacked pcb patch finished in a constant temperature and humidity environment preservation period of 15 days, not more than 3 days at room temperature.
5. Unpacked pcb should be used up within 3 days, not used up need to re-use static bags vacuum sealed.
6. SMT patch and DIP after the pcb board to be transported and placed with anti-static bracket.
