Abstract
With the double-sided wiring board of printing word measuring ability, relate to wiring board production field.Comprise wiring board, wiring board is arranged multiple electrical measurement unit, each electrical measurement unit includes intralamellar part and divides and edges of boards part, the corresponding test symbol of each electrical measurement unit on wiring board, described test symbol comprises round layers of copper, circle layers of copper is provided with the through hole of through wiring board, through-hole wall is provided with the copper plate for conducting circle layers of copper and wiring board back copper foil layer; Circle layers of copper also covers the insulated openings layer exposing round layers of copper completely; Circle layers of copper is also coated with the circular character layer with wire mark while of the word divided with intralamellar part in wire mark operation.The utility model structure is simple, can realize quick and easy, accurately to realize skip printing of characters, wrongly typed or text excursion detection management and control.
Description
Technical field
The utility model relates to wiring board production field, is specially a kind of double-sided wiring board with printing word measuring ability.
Background technology
Wiring board is widely used in electronics field, particularly on the consumer electronics product such as mobile phone, notebook computer; Existing line plate often needs the word ink of clipsheet, two or more multiaspect time in process of production, and the phenomenon of skip printing of characters, wrongly typed or text excursion now often occurs.
Utility model content
The purpose of this utility model is to provide a kind of double-sided wiring board with printing word measuring ability, can carry out detection management and control when electrical measurement (short/out of circuit test) to the phenomenon of skip printing of characters, wrongly typed or text excursion.
The technical scheme realizing above-mentioned purpose is: with the double-sided wiring board of printing word measuring ability, comprise wiring board, wiring board is arranged multiple electrical measurement unit, each electrical measurement unit includes the edges of boards part of shaping rear removal that intralamellar part divides and is positioned at intralamellar part point periphery, it is characterized in that: the corresponding test symbol of each electrical measurement unit on described wiring board, described test symbol is arranged at the edges of boards part of each electrical measurement unit side, described test symbol comprises round layers of copper, circle layers of copper is provided with the through hole of through wiring board, through-hole wall is provided with the copper plate for conducting circle layers of copper and wiring board back copper foil layer, circle layers of copper is also coated with the insulated openings layer exposing round layers of copper completely, circle layers of copper is also coated with the circular character layer with wire mark while of the word divided with intralamellar part in wire mark operation, circular character layer is concentric with circle layers of copper, and the outer rim of circular character layer equals the misalignment tolerances of printing word to the distance between circle layers of copper outer rim.
Above-mentioned electrical measurement unit is divided into multiple electrical measurement unit according to large young pathbreaker one piece of wiring board of electrical measurement fixture, and each electrical measurement unit matches with the size of electrical measurement fixture.
Test philosophy of the present utility model: during electrical measurement, wiring board is placed on electrical measurement fixture, being contacted with the round layers of copper at test symbol place on wiring board by the detection pin of electrical measurement fixture, (this detects pin for PIN always, its lower end diameter is identical with circular character layer diameter, so that detect pin fully can cover circular character layer under round layers of copper), because circular character layer is insulation shape ink, if omit wire mark operation when producing or wire mark skew occur, circular character layer or this circular character layer skew also would not be printed off so that exceed text excursion tolerance by the test symbol place being then positioned at edges of boards part, now just can expose round layers of copper, at this moment the detection pin of electrical measurement fixture just can directly be touched round layers of copper and is conducted by the copper foil layer at via and the test symbol back side, final generation test short circuit also sends alarm signal.
The detection pin of electrical measurement fixture, one end contacts with the flexible layer on wiring board, and the other end is connected on computer by conductive device, to show test results.
The utility model structure is simple, can realize quick and easy, accurately to realize skip printing of characters, wrongly typed or text excursion detection management and control.
Accompanying drawing explanation
Fig. 1 is schematic diagram of the present utility model;
Fig. 2 is the structure chart of test symbol.
Embodiment
As shown in Figure 1, 2, the utility model comprises wiring board 1, wiring board 1 is arranged multiple electrical measurement unit 2, each electrical measurement unit 2 includes intralamellar part and divides 3 and be positioned at the edges of boards part 4 that intralamellar part divides the shaping rear removal of 3 peripheries, the corresponding test symbol 5 of each electrical measurement unit 2 on wiring board 1.
Test symbol 5 is arranged at the edges of boards part 4 of each electrical measurement unit 2 side, test symbol 5 comprises round layers of copper 6, circle layers of copper 6 is provided with the through hole 7 of through wiring board 1, through hole 7 inwall is provided with the copper plate 8 for conducting circle layers of copper 6 and wiring board 1 back copper foil layer (not shown); Circle layers of copper 6 is also coated with the insulated openings layer 9 exposing round layers of copper 6 completely; Circle layers of copper 6 is also coated with and the circular character layer 10 dividing the simultaneously wire mark of the word on 3 in wire mark operation with intralamellar part, circular character layer 10 is concentric with circle layers of copper 6, and the outer rim of circular character layer 10 equals the misalignment tolerances R of printing word to the distance between circle layers of copper 6 outer rim.
