Abstract
The utility model discloses a be convenient for discern the circuit board of defective products. The cell board that the circuit board is in the same place including a plurality of concatenations of whole production, each cell board sets up the identifier after detecting the classification, the identifier paste in on the cell board, the identifier is circular copper sheet, the identifier sets up on the cell board that detects unqualified final rejection. The circuit board divides behind the board easily discernment and scraps board and problem board, improves discernment efficiency, and can effectively improve because of milling the copper sheet warpage that the target caused, stops therefore to the influence of subsequent handling, on the other hand pastes the process and compares and current mill the target mode, changes the operation, and is efficient, with low costs, effectual.
Description
Technical field
The utility model relates to wiring board technical field.
Background technology
Printed wiring board in process of production, conventionally the justifying that multiple cell boards is stitched together is produced, but because the quality of each cell board in process of producing product is uneven, particularly for there being major defect need to scrap certain cell board of processing, conventional method is the identification of milling target, while inspection outside, drill through more than one target at former wiring board plate face, as scrapping mark. Because wiring board plate face is furnished with compared with multi-line, in milling target process, easily the circuit around target is out of shape to warpage, because milling cutter High Rotation Speed again melts the PP dielectric layer material of circuit below and forms copper powder that melting dust grinds with circuit surface and mix and splash down and stick at wiring board justifying plate face difficult drop-off, affect subsequent handling in addition. For example, in the time carrying out silk-screen, the part of circuit distortion warpage easily punctures the half tone of silk-screen or damage, and causes half tone silk-screen again; And developing, when surface treatment because chemical medicinal liquid carries out chemical reaction at the copper powder of plate face, easily Pollution Chemistry liquid medicine with sticking; In finished product test process, also can very easily there is micro-short, the short circuit phenomenon of test because copper powder particle exists in addition, cause finished product test yield not high.
Utility model content
In view of this problem that, the utility model need to solve is to provide a kind of wiring board of the defective products of being convenient to identification.
In order to address the above problem, the utility model is by the following technical solutions: a kind of wiring board of the defective products of being convenient to identification, the some cell boards that are stitched together that comprise integral production, described unit plate arranges identifier after classifying after testing, and described identifier is pasted on described cell board.
Preferably, described identifier is circular copper sheet.
Preferably, described circular copper sheet diameter is 1 to 10CM.
Preferably, described identifier is arranged on the cell board that detects defective final rejection.
Compared with prior art, wiring board described in the utility model divides and is easy to identification after plate and scraps plate and problem board, improves recognition efficiency, and can effectively improve the copper sheet warpage causing because of milling target, stop the therefore impact on subsequent handling, ensure product quality, improving product yield 3% left and right; On the other hand, paste operation and compare existing milling target mode, more easy to operate, efficiency is high, and cost is low, effective.
Brief description of the drawings
Fig. 1 is circuit board structure schematic diagram described in the utility model.
Detailed description of the invention
Below in conjunction with drawings and Examples, the utility model is described in further detail.
As shown in Figure 1, the wiring board 10 of the defective products of being convenient to identification described in the utility model, formed by polylith junior unit plate 12, this is for convenient for production, by multiple cell board integral layouts, the integral manufacturing film, integral manufacturing circuit etc., unit plate edges of boards arrange die-cut trace, after integral manufacturing completes, and punching molding. Before the overall silk-screen of wiring board 10, carry out Performance Detection, even need the plate of directly scrapping to distinguish qualified products, substandard product. The cell board that the utility model is scrapped mainly for need indicates. As shown in the figure, identifier 14 is circular copper sheet, and it is adopted and is arranged in the method for paste on the cell board that detects defective final rejection.
When stickup, need to adopt the glue of high temperature resistant (at least resistance to 150 degree high temperature), difficult drop-off, so that posterior polish-brush, roasting procedure can not move or come off, and glue need can not react with liquid medicine in follow-up processing solution tank.
The size of circular copper sheet determines according to the size of cell board, and obviously identifying and be as the criterion, general copper sheet diameter is 1 to 10CM suitable.
Above-described embodiment is only preferably implementation of the present utility model, and it describes comparatively concrete and detailed, but can not therefore be interpreted as the restriction to the utility model the scope of the claims. It should be pointed out that for the person of ordinary skill of the art, without departing from the concept of the premise utility, can also make some distortion and improvement, these apparent replacement forms all belong to protection domain of the present utility model.
Claims (4)
1. be convenient to a wiring board for the defective products of identification, comprise some cell boards that are stitched together of integral production, it is characterized in that: described unit plate arranges identifier after classifying after testing, and described identifier is pasted on described cell board.
