Embodiment Construction
[0032] The present invention will be further elaborated below in conjunction with the accompanying drawings and embodiments.
[0033] With reference to the accompanying drawings, a 3D transfer PCB board includes a PNL board 1 and a PCB board 3 located on the PNL board. The PCB is provided with at least one inner groove 6, and the edge of the inner groove 6 is provided with Edge wrapping groove 5 and connection position 4, the connection position is used to connect between each inner groove, and between the inner groove and the PNL board. Reference attached figure 1 The PNL board is composed of 6 SET boards 2, each SET board includes 12 PCB boards, and each PCB board is provided with an inner groove 6.
[0034] A method for manufacturing a 3D transfer type PCB board, the PNL board is followed by the following steps:
[0035] S1: Carry out cutting, baking, copper reduction and drilling on the PNL board in sequence. PNL board cutting substrate is made of high TG and CAF-resist...
