Description

Technical Field

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

[0002] The production process of multi-layer circuit boards is divided into: inner layer circuit production, lamination, drilling, electroplating, solder mask production, surface treatment, molding, electrical performance testing, and final inspection. The lamination step is further divided into stacking and lamination. Stacking is to stack the core board with the inner layer circuit and the prepreg according to the design requirements. The copper foil lamination equipment covers both sides of it with copper foil, and then the laminated materials are pressed together under high temperature and high pressure to form a multi-layer circuit board.

[0003] However, in actual use, the lamination step is often done manually. Workers stack the core board and prepreg as required, and then place them in the processing position of the copper foil board equipment. The copper foil board equipment covers both sides of it with copper foil. Since the transparency of the prepreg is not high, the prepreg is generally placed between two adjacent core boards, and 1-3 prepregs may be placed between adjacent core boards. When workers place the core board, the placement of multiple prepregs greatly reduces the transparency, which easily leads to inaccurate alignment of the upper and lower core boards. For this reason, we propose a multi-layer circuit board alignment monitoring device. Utility Model Content
