Description

Technical Field

[0001] The utility model belongs to the technical field of multi-layer circuit board pressing, and in particular relates to a multi-layer circuit board pressing device. Background Art

[0002] The manufacturing method of multilayer boards generally starts with making the inner layer graphics first, and then using the printing and etching method to make a single-sided or double-sided substrate, and incorporating it into the specified interlayer, and then heating, pressurizing and bonding it. As for the subsequent drilling, it is the same as the plated through hole method of the double-sided board. When pressurizing the multilayer circuit board, a press machine is required for processing. When using the existing multilayer circuit board press machine, it is generally used to push the press plate through the lifting mechanism to press the multilayer circuit board. However, when the press plate is connected to the lifting plate, it is generally fixed by plugging, and there is no docking limit and positioning structure. Therefore, the connection is not stable enough, which may cause uneven pressure. For this reason, we propose a multilayer circuit board pressing device. Utility Model Content
