Embodiment Construction

[0021] The embodiments of the present invention will be described in detail below with reference to the accompanying drawings, but the present invention can be implemented in many different ways defined and covered by the claims.

[0022] Please refer to figure 1 , the present invention provides a punching device for a PCB substrate (especially a double-sided sandwich aluminum substrate), comprising: a fixed lower mold part and an upper mold part that moves relative to the lower mold part; the upper mold part includes shearing plates 1, The upper mold core 2 and the upper mold ejection mechanism; the shearing plate 1 includes a cavity, and the upper mold core 2 is movably arranged in the cavity; the upper mold ejection mechanism drives the upper mold core 2 to move relative to the cavity towards the direction of the lower mold.

[0023] Please refer to figure 1 , when punching the board, the PCB substrate 15 is placed in the gap between the upper mold part and the lower mold ...

Abstract

The invention provides a PCB substrate stamping device. The PCB substrate stamping device comprises a lower die portion and an upper die portion, wherein the lower die portion is fixedly arranged, and the upper die portion moves relative to the lower die portion. The upper die portion comprises a shearing plate, an upper die core and an upper die retreating mechanism. The shearing plate comprises a cavity, and the upper die core is movably arranged in the cavity. The upper die retreating mechanism drives the upper die core to move towards the lower die portion relative to the cavity. By the adoption of the structure, an insulating layer can be prevented from cracking, the rate of finished products and production efficiency are improved, potential quality hazards are eliminated, and the condition that poor high-pressure may occur after reflow soldering is avoided.

Description

technical field [0001] The invention relates to the field of printed circuit board manufacturing, in particular to a PCB substrate punching device. Background technique [0002] With the development of PCB and LED industries, the market demand for double-sided sandwich aluminum substrates is increasingly strong. The feature of this product is that the upper and lower sides of the aluminum substrate must be equipped with electronic components. It must withstand high voltage and also have a good heat dissipation function. If the above functions are to be satisfied at the same time, when punching the board, no insulation layer is allowed to burst. problem, otherwise the high-voltage test will fail; according to conventional methods, ordinary molds cannot meet the requirements, and at least one side of the insulation layer will burst. If the mold design is reasonable and no other actions are taken before punching to help the product reduce extrusion during the punching proc...
