Abstract

The invention discloses a microphone printed circuit board (pcb) high in utilization rate and a lower punching die structure thereof. The microphone pcb comprises a microphone pcb base material and a lower punching die. The microphone pcb base material is provided with a microphone unit and leftovers. The lower punching die is provided with an upper left basic limiting angle block, an upper right basic limiting angle block and a lower limiting check block. The upper left basic limiting angle block, the upper right basic limiting angle block and the lower limiting check block are used for wrapping and positioning the periphery of the microphone pcb base material. The microphone pcb is free of technological plate edges required by a conventional circuit board base material, the punching process for positioning basic holes is eliminated, and the finished microphone pcb is directly formed; the number of punching procedures is small, the punching cost is low, the utilization rate of pcb materials is increased, and economic benefits are remarkable.

Description

technical field [0001] The invention relates to the field of stamping and forming of circuit boards, in particular to a microphone PCB board with high utilization rate and its stamping lower die structure. Background technique [0002] In the circuit board, the switches of the produced microphone products are all reflected on the base material, and the number of the CAM data operation panel is 320 small microphones, and the punching die is designed with 4 punch positioning holes to complete the positioning; its layout The utilization rate of the base material of the circuit board with through holes is low, which increases the cost of raw materials, and this type of circuit board needs secondary stamping, and the process positioning round hole and the process positioning waist hole for positioning on the edge of the forming board need to be stamped once , the second stamping is used to form pcb microphone head products. Contents of the invention [0003] The purpose of the...
