Storage requirements for PCBA assembly boards

The storage requirements for PCBA assembly boards mainly include environmental temperature and humidity control, anti-static measures, and appropriate packaging protection.

Environmental temperature and humidity control: The storage environment of PCBA boards should maintain appropriate temperature and humidity to avoid moisture or excessive drying of the boards, thereby ensuring the quality of welding points. For ordinary boards, it is recommended to control the storage environment temperature between 22-30 ℃ and humidity between 30-60% RH. For PCBA using OSP technology, storage requirements are stricter and must be stored in a constant temperature and humidity cabinet to ensure environmental stability and consistency. Welding should be completed within 24 hours to avoid oxidation of the solder pads.

Anti static measures: The PCBA board should be placed on an anti-static rack to avoid static electricity loss. In areas sensitive to static electricity, the room temperature should be controlled between 15 ℃ and 30 ℃, with a relative humidity of 45-75%. It is prohibited to operate in environments below 45% to reduce the impact of static electricity on PCBA.

Appropriate packaging protection: For PCBA boards that are not used for a long time, it is recommended to take additional protective measures, such as applying three proof paint to improve the moisture and mold resistance of the board. Meanwhile, using vacuum packaging can effectively isolate external air and prevent oxidation of the board. The storage and transportation box should use anti-static materials, and the internal structure should include anti-static grids and anti-static foam to ensure the safety of the PCBA board during transportation and storage.

In summary, the storage requirements for PCBA boards cover multiple aspects such as environmental conditions, anti-static measures, and packaging protection, aiming to ensure that the quality and performance of PCBA boards are not affected during storage.
