Description

Technical Field

[0001] The utility model relates to the technical field of PCBA board processing, in particular to a drying device used for PCBA board processing. Background Art

[0002] PCBA board refers to a product that fixes electronic components (such as resistors, capacitors, inductors, ICs, etc.) on PCB by welding or plugging. PCB is the basis of PCBA. It is an insulating substrate used for electrical connection between electronic components. Through pre-designed circuit patterns and holes, the connection between components becomes simple and convenient. PCBA board drying is an important part of the PCBA manufacturing process. It is mainly used to remove moisture from the board to ensure that the electronic components will not malfunction due to moisture in the subsequent work process. In actual use, after drying, the PCBA board or placement rack needs to be manually removed from the drying equipment by personnel. If the PCBA boards are taken out one by one, it will consume a lot of time and labor. In addition, the PCBA board or placement rack that has just been dried is in a high temperature state and is easy to come into contact with the skin of personnel, causing the risk of burns. Therefore, a drying device for PCBA board processing is now provided. Utility Model Content
