Method for identifying whether PP sheets are stacked correctly or not

Abstract

The invention discloses a method for identifying whether PP sheets are stacked correctly or not. The method comprises the following steps: S1, rough shape cutting; S2, drilling; S3, determining the stacking sequence and stacking, preparing a plurality of PCBs to be stacked, determining the stacking sequence of the PCBs and the PP sheets, providing the edge of one side of each PP sheet with a protruding part, stacking the PP sheets and the PCBs together according to a certain sequence to form a multi-layer laminated board, and arranging the protruding parts on the same side of the multi-layer laminated board and enabling the protruding parts to extend out of the multi-layer laminated board; sequentially arranging the positions of the plurality of protruding parts in a staggered mode according to the stacking sequence, and enabling the distances between the adjacent protruding parts to be equal. S4,carrying out hot melting and riveting; and S5, checking: checking whether the lug bosses are overlapped or vacant, if so, judging that the PP sheets are wrongly stacked, and if not, judging that the PP sheets are correctly stacked. According to the invention, whether the PP sheet is lackedor repeatedly placed can be visually identified, the identification is rapid, the efficiency is improved, the management is convenient, the operation difficulty and the inspection cost are reduced, and the quality of the PCB is ensured.

Description

technical field [0001] The invention relates to the field of PCB boards, in particular to a method for identifying whether PP sheets are stacked correctly. Background technique [0002] In circuit board products whose application scenarios are high-voltage or high-current transmission, in order to ensure good insulation properties of the product, customers generally adopt a laminated structure design of multiple PP sheets between adjacent signal layers, and the laminated structure of some products It even contains multiple PP sheets of different specifications. The stacking quantity and order of PP sheets of this type of product are directly related to whether the final PCB product can meet the performance requirements of the design, so how to avoid over-placement, under-placement or misplacement of PP sheets during lamination The problem of other positions has become the focus and difficulty in the pressing process. [0003] At present, PP with different stacking position...
