Abstract
The utility model discloses a novel circuit board positioning structure, which comprises a circuit board. The circuit board is provided with a plurality of pin holes used as zero positions for drilling. The centers of the pin holes are overlapped with the centerline of the surface of the board, the distance L between the pin holes and the edge of the board is 2mm, and the tolerance of position accuracy is plus or minus 0.5mm. The defects of the prior art are overcome, the novel circuit board positioning structure is simple, and the accuracy of drilling and circuit positioning is improved.
Description
[technical field]
The utility model relates to the novel location structure of a kind of circuit board.
[background technology]
Along with the develop rapidly of electronic technology, electronic product more and more trends towards multifunction, miniaturization, and this impels the printed circuit board as electronic component installation basis to develop to multiple stratification, laminationization, densification direction.More and more higher to boring and the requirement of circuit aligning accuracy, and the positional precision of boring directly has influence on the precision of circuit contraposition and integrated electronics processing.Existing location structure generally is to get location point on the angle arbitrarily to set the location zero-bit on four angles of circuit board, this location structure error is relatively big, when changing because of personnel's machine simultaneously, position disparity is bigger, is difficult to transfer to the batch automatic production scale
[utility model content]
The utility model purpose is to have overcome weak point of the prior art, provides a kind of simple in structure, can improve the novel location structure of circuit board of boring and circuit aligning accuracy
In order to solve the technical problem of above-mentioned existence, the utility model adopts following technical proposal:
The novel location structure of a kind of circuit board, comprise circuit board, be provided with a plurality of pin holes, described pin hole design: the central lines of its Kong Xinyu plate face as the boring zero-bit at described circuit board, the distance L of described pin hole and edges of boards is 2mm, the positional precision tolerance is+/-0.5mm.
The novel location structure of aforesaid a kind of circuit board, it is characterized in that two same horizontal linears pin hole tolerance for+/-0.5mm.
The utility model compared with prior art has following advantage:
Be provided with two pin holes at described circuit board in the utility model as the boring zero-bit, the central lines of its Kong Xinyu plate face of described pin hole, adopt the utility model structure that circuit board is reorientated, satisfy the assembly precision requirement of high-density layer, high integrated electronics, improved the qualification rate in the manufacture process, but production process automation control, stay in grade has reduced the production cost that same precision requires.
[description of drawings]
Fig. 1 is a schematic diagram of the present utility model;
Fig. 2 is the enlarged drawing at A place among Fig. 1.
[embodiment]
Below in conjunction with accompanying drawing the utility model is described in detail:
The novel location structure of a kind of circuit board as illustrated in fig. 1 and 2, comprise circuit board 1, be provided with two pin holes 2 at described circuit board 1 as the boring zero-bit, the center line 3 of described pin hole 2 its Kong Xinyu plate faces overlaps, described pin hole 2 is 2mm with the distance L of edges of boards, the positional precision tolerance is+/-0.5mm.The tolerance of the pin hole 2 of two same horizontal linears is+/-0.5mm.
The technological process of adopting the utility model location structure to produce circuit board comprises:
--------machine bores pin hole, and---------------------------------------roasting behind the wrongly written or mispronounced character------------------------inspection------is packed------shipment to green oil to graphic plating to outer-layer circuit (using optical registration) to panel plating to heavy copper to the Kai material eventually in test in moulding in surface treatment to move back the film etching to do zero-bit boring with pin hole in the borehole data design
Wherein said drilling data design: pin hole is on the center line of jigsaw size, as the plate width is 400mm, pin hole design is in the 200mm position, and both sides equalization, position of related features be+/-0.5mm, pin hole 2 hole back gauge edges of boards 2mm, position of related features is+/-0.5mm, two pin hole upright position tolerances are+/-0.5mm, do the boring zero-bit with one of them pin hole, and with new bore to chew get out the optical registration hole that the circuit contraposition is used, the contraposition design deviation is+/-0.025mm.Do drilling at drilling operating with above design parameter and hole, accomplish the circuit operation, with the contraposition of automated optical exposure machine by normal flow. can finish the control of boring hole site precision and circuit aligning accuracy.
