Abstract
The utility model discloses a printed circuit board preventing character printing omission. The printed circuit board preventing character printing omission includes a printed circuit board body and strip-shaped board edges surrounding the circuit board body. The board edges in four directions of the circuit board body are provided with at least one character printing omission testing unit each. Each character printing omission testing unit includes two or more pads in electric conduction. According to the utility model, the character printing omission testing units are arranged on the printed circuit board, so that character printing omission can be detected quickly, automatically and accurately and products with printing omission errors can be prevented from being output into market effectively. Therefore, product quality control can be facilitated.
Description
Technical field
The present invention relates to printed substrate production technical field, relate in particular to the printed substrate that a kind of anti-text printout is bitten.
Background technology
In printed substrate production process, text printout operation can be printed the word marking for indicating on printed substrate.Because of defect or personnel's operate miss of production technology, in text printout operation, easily there is justifying or partly bite.Existing way is by producers' visual detection, gets rid of the wiring board of biting, and inefficiency and accuracy are low.
Summary of the invention
In view of this, the utility model discloses the printed substrate that a kind of energy is accurate, Quick Measuring is made skip printing of characters situation.
The purpose of this utility model is achieved through the following technical solutions: a kind of printed substrate of anti-skip printing of characters, comprise printed substrate body and be looped around the bar shaped edges of boards of wiring board body, it is characterized in that: described wiring board body is forward and backward, be respectively equipped with at least one skip printing of characters test cell on seat, right edges of boards; Described skip printing of characters test cell comprises the pad of two or more conductive communication.
Between any two pads in same skip printing of characters test cell, can connect by wire.During normal printing, text printout oil can effectively completely cut off the conduction of any two pads in same skip printing of characters test cell.Therefore complete after text printout operation, measurement circuit plate body is forward and backward, the conduction of any two pads of the skip printing of characters test cell of seat, right arbitrary edges of boards, can go out the printed substrate that justifying is bitten by Effective selection.The conduction of all skip printing of characters test cells in the forward and backward ,Zuo, of measurement circuit plate body upper right, can go out the printed substrate of biting in subregion by Effective selection.
Further, described wiring board body comprises line areas and logicalnot circuit district, and described logicalnot circuit district is provided with skip printing of characters test cell described at least one.
For increasing, the accuracy of detection ， logicalnot circuit district of printed substrate skip printing of characters is provided with to same skip printing of characters test cell, thereby increases its Test coverage area, prevent undetected.
Further, on described edges of boards, every two solder pad space lengths of skip printing of characters test cell are 1-10cm.
When on edges of boards, every two solder pad space lengths of skip printing of characters test cell are 1-10cm, its test result has higher precision during for identification printed substrate skip printing of characters situation.
Preferably, the skip printing of characters test cell in described logicalnot circuit district comprises the pad of two conductive communication.
Preferably, two pads of the skip printing of characters test cell in described logicalnot circuit district are separately positioned on the position that Shang Yu line areas, logicalnot circuit district joins.
The utility model, with respect to prior art, has advantages of as follows:
1. the utility model arranges skip printing of characters test cell on printed substrate, can fast and automatically, accurately filter out the printed substrate of the word of biting, and can effectively prevent that the product of biting from coming into the market, and is conducive to control the quality of product.
2. the utility model arranges respectively skip printing of characters test cell in the edges of boards of the front, rear, left and right of wiring board body and logicalnot circuit district, can detect respectively justifying skip printing of characters or the subregion situation of biting, and is applicable to the different working conditions that require.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is another example structure schematic diagram of the utility model.
Embodiment
For the ease of it will be appreciated by those skilled in the art that below in conjunction with accompanying drawing and embodiment, the utility model is described in further detail:
The present embodiment provides a kind of printed substrate of anti-skip printing of characters, comprises printed substrate body 1 and is looped around the bar shaped edges of boards 2 of wiring board body, and described wiring board body is forward and backward, be respectively equipped with a skip printing of characters test cell on seat, right edges of boards; Described skip printing of characters test cell comprises two pads that connect by wire conducting 3.
In the present embodiment, in above-mentioned same skip printing of characters test cell, two pad 3 spacing are 1cm.
During normal printing, text printout oil can effectively completely cut off the conduction of any two pads in same skip printing of characters test cell.Therefore complete after text printout operation, measurement circuit plate body is forward and backward, the conduction of any two pads of the skip printing of characters test cell of seat, right arbitrary edges of boards, can go out the printed substrate that justifying is bitten by Effective selection.The conduction of all skip printing of characters test cells in the forward and backward ,Zuo, of measurement circuit plate body upper right, can go out the printed substrate of biting in subregion by Effective selection.
The present embodiment provides a kind of printed substrate of anti-skip printing of characters, comprises printed substrate body 1 and is looped around the bar shaped edges of boards 2 of wiring board body 1, and described wiring board body 1 is forward and backward, be respectively equipped with a skip printing of characters test cell on seat, right edges of boards; Described skip printing of characters test cell comprises two pads that connect by wire conducting 31.Described wiring board body comprises 11Ji logicalnot circuit district, line areas 12, and described logicalnot circuit district is provided with skip printing of characters test cell described at least one.The skip printing of characters test cell in described logicalnot circuit district comprises the pad 32 of two conductive communication.Two pads of the skip printing of characters test cell in described logicalnot circuit district are separately positioned on the position that Shang Yu line areas, logicalnot circuit district joins.
In the present embodiment, in the same skip printing of characters test cell of above-mentioned edges of boards, two solder pad space lengths are 5cm.
Be more than wherein specific implementation of the present utility model, 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 range of the present utility model.
