Embodiment Construction

[0029] The invention provides a printed circuit board before forming and cutting, please refer to Figure 2A , including a circuit board 200 with the outer circuit, wherein the circuit board 200 exposes the circuit connection part 210 for connecting a plurality of gold fingers 220, and the gold finger 220 includes a protruding part 221 and a main part 222, and has a concave section form (see Figure 2B , side view of the circuit board), the length D1 of the protruding portion 221 is generally about 2 to 10 mils, the length D1 can be adjusted according to actual needs, and is not limited to this range. In addition, a forming path 30 ( AA′ is the boundary of the molding path) extending along the edge of the circuit board 200 adjacent to the protruding portion 221 of the golden finger. The main feature of the circuit board 200 is that there is a distance D2 between the gold finger protruding portion 221 and the forming path 30 , and the distance D2 is greater than 2 mils, prefer...

Abstract

The invention provides a printed circuit board before being formed and cut and a manufacturing method thereof. The circuit board comprises: a circuit board with a complete external-layer circuit, wherein the circuit board exposes a circuit connecting part; a plurality of connecting gold fingers which are connected with the circuit connecting part and provided with a main part and a protruding part; and a forming route which extends along the edge of the circuit board of the protruding part, wherein a certain distance of over 2 milli-inches is reserved between the forming route and the protruding part. Because of a certain distance reserved between the forming route and the protruding part, the problem of the connecting finger stripping caused during forming and cutting is solved.

Description

technical field [0001] The invention relates to a printed circuit board, and in particular to a printed circuit board before forming and cutting and its manufacturing method. Background technique [0002] With the vigorous development of the electronics industry, the printed circuit board (PCB) has become an indispensable and important component. According to the circuit design, various electronic components are combined to achieve the purpose of signal processing, while the printed circuit board The design quality of the board not only directly affects the reliability of electronic products, but also affects the overall performance of the product. Therefore, each process of PCB is very important, and it must be controlled through precise process to obtain various required circuits. plate. [0003] Among them, before forming and cutting, in order to make the board meet the specification and size required by the customer, CNC forming machine (or mold punching machine) will b...
