Description

Technical Field

[0001] The utility model relates to the field of baking plate equipment, in particular to a batch baking plate equipment for PCB circuit boards. Background Art

[0002] PCB board, also known as printed circuit board, is the provider of electrical connections for electronic components. During the production process of PCB boards, the PCB boards need to be baked to remove excess moisture adsorbed by the PCB boards from the external environment and to increase the welding effect during PCB board processing. Therefore, a PCB circuit board batch baking equipment is needed.

[0003] Most of the existing baking plates of the baking plate equipment cannot be effectively disassembled, so before baking, most of them require the staff to transfer the prepared circuit boards to the baking plates of the baking plate equipment for a second time, which is relatively troublesome. Moreover, most of the existing baking plate equipment cannot quickly dissipate the heat of the circuit boards after baking, so after the circuit boards are baked, it may take a certain amount of time for natural heat dissipation to enable the staff to take the circuit boards, thereby greatly reducing the work efficiency. Therefore, technical improvements are urgently needed. Utility Model Content
