Problems solved by technology

At present, for cardboard products, various PCB manufacturers use CNC to drill out the card slot. The tolerance of this kind of conventional CNC forming is too large, which can easily cause the slot hole and the gold finger to be partially offset. Failure to meet customer requirements will cause a relative offset between the position of the card slot and the position of the gold finger due to insufficient precision.

Embodiment Construction

[0020] The manufacturing method of the card slot of the Goldfinger graphics card board of the present invention will be described in further detail below with reference to specific embodiments.

[0021] A non-limiting embodiment of the present invention is a method for manufacturing a card slot of a Goldfinger graphics card. The graphics card slot is drilled by a drilling method, and the drilling tolerance is less than ±0.10mm, including the following steps:

[0022] S1, add slotted holes in the drilling production table and drilling belt, and drill the slot at the position of the slotted hole during drilling production;

[0023] S2, the position of the slot added in step S1 is marked in the outline drawing, so as to prevent the CNC from repeating the slot during the molding process.

[0024] In this embodiment, the position of the slot hole is completely drilled by the drilling method, instead of forming the gong slot in the later stage, which can avoid the damage of the slot...

Abstract

The invention relates to a manufacturing method of a golden finger graphics card card slot, which adopts a drilling mode to drill the graphics card card slot, and comprises the following steps of: S1, adding slot holes in a drilling production table and a drilling belt, and drilling a card slot at the position of the slot hole during drilling production; and S2, marking the positions of the slotted holes added in the step S1 in the profile drawing to prevent the slotted holes from being milled again by CNC (computer numerical control) during forming treatment. The manufacturing method of the golden finger display card slot has the advantages that the conception is ingenious, the size and offset precision of the slot are high, the combination area of the golden finger and a component is effectively improved, and unstable signals and signal loss caused by poor contact are reduced.

Description

technical field [0001] The invention relates to the technical field of graphics card board manufacturing, in particular to a manufacturing method of a card slot of a gold finger graphics card board. Background technique [0002] With the rapid development of the circuit board industry and the upgrading of products, the quality requirements for Goldfinger graphics card boards are also getting higher and higher. mm or less. At present, for card board products, various PCB manufacturers use the method of CNC gong to pull out the card slot for the card slot. The tolerance of this kind of conventional CNC molding is too large, which can easily lead to the deviation between the slot hole and the gold finger. If the customer's requirements cannot be met, the position of the card slot and the position of the gold finger will be relatively offset due to insufficient precision. SUMMARY OF THE INVENTION [0003] The invention provides a card slot of a gold finger graphics card boar...
