Abstract
The present utility model relates to a circuit board, specifically to a printed circuit board for the circuit board process capability inspection. The circuit board is provided with hole inner copper depth and electroplate covering power testing sheets, plate inner layer connection thermal stress testing sheets, inner layer contraposition precision testing sheets, copper plating conduction capability testing sheets, hole inner copper plating combination capacity testing sheets, surface pad tinning capability testing sheets, drilling hole wall status and press plate combination capability testing sheets and line width and line space testing sheets, and the testing sheets are independently arranged on the circuit board. Through the testing circuit board, the whole technology and process capability of the circuit board production can be monitored, problems and improvements of the process can be reflected at any time, the situation of adding testing sheets on finished product plates by each customer and discarding production plates due to testing can be avoided, the material cost can be saved, and the circuit board is favorable for the statistic analysis of detection data.
Description
Technical field
The utility model relates to a kind of printed substrate, refers in particular to a kind of test and uses printed substrate.
Background technology
Continuous upgrading along with modern electronic product; The number of plies of wiring board is in continuous increase; The high density interconnect plate is also in a large amount of productions; So just require the making ability of wiring board to improve constantly, will do strong monitoring to the processing procedure ability of wiring board, therefore a good processing procedure ability detection line plate just has been necessary.Traditional wiring board processing procedure ability is to adopt destruction production plate or each test all to do the mode that a breadboard goes to detect relevant processing procedure ability when detecting.The shortcoming of doing so at first is to have caused raw-material waste; Secondly part production board because of test causes quantity not enough, can not deliver goods by customer demand; Be exactly thereby that the data of at every turn doing are not easy to the situation of change that comparison can't be grasped wiring board processing procedure ability in addition.
The utility model inventor has proposed a kind of new technical scheme to the problems referred to above, has overcome above-mentioned technological deficiency well.
The utility model content
The utility model is to the disappearance of prior art existences, and its main purpose provides and a kind of printed substrate manufacture craft, equipment, processing procedure ability can comprehensively be represented, is convenient to do wiring board check and data analysis, special use.
For realizing above-mentioned purpose; The utility model adopts following technical scheme: a kind of measurement circuit plate is characterized in that: it is thick and electroplate tin aptitude tests sheet, borehole wall situation and pressing plate binding ability test pieces and live width line-spacing test pieces on the binding ability test pieces, surface pads of electro-coppering in covering power test pieces, inner cord connection thermal stress test pieces, internal layer contraposition accuracy test pieces, copper facing ducting capacity test pieces, the hole that said wiring board is provided with the copper hole in; Said test pieces is separate to be distributed on the wiring board.
Said wiring board is 14 laminates, thickness of slab 3.0mm, and the minimum-value aperture is 0.25mm; The aperture aspect ratio, promptly the minimum ratio of plank thickness and minimum aperture diameter is 12:1.
After the utility model adopts technique scheme; Its beneficial effect is: on the utility model wiring board set test pieces easily on the slave plate hand get off; Every kind of test pieces is provided with two at least; For some strict process test pieces even be provided with more than ten, be convenient to data statistics and analysis.Through this measurement circuit plate whole technology, the processing procedure ability of wiring board production played supervisory function bit; Problem in the processing procedure is reflected with improving at any time; Need not each client on production board, set up test pieces; Or scrap the production plate because of test, and practiced thrift material cost, also be beneficial to the statistical analysis that detects data simultaneously.
Description of drawings
Fig. 1 is the composition structural representation of the utility model.
Embodiment
Come the utility model is elaborated below in conjunction with accompanying drawing and specific embodiment: a kind of measurement circuit plate that is illustrated in figure 1 as the utility model; This wiring board is a rectangle; And which is provided be used to detect in the hole copper thick and electroplate covering power, inner cord connects thermal stress, borehole wall situation and pressing plate binding ability test pieces 1; Be used to detect internal layer contraposition accuracy test pieces 2, be used to detect copper facing ducting capacity test pieces 3; Be used to detect tin aptitude tests sheet 4 on the surface pads, be used to detect the test pieces 5 of sheet material fusing point and be used to detect live width line-spacing test pieces 6; Said test pieces is separate to be distributed on the wiring board.
Wherein said wiring board is 14 laminates, thickness of slab 3.0mm, and the minimum-value aperture is 0.25mm; The aperture aspect ratio, promptly the minimum ratio of plank thickness and minimum aperture diameter is 12:1.
Focusing on of the utility model; On the utility model wiring board set test pieces easily on the slave plate hand get off; Every kind of test pieces is provided with two at least, for some strict process test pieces even be provided with more than ten, is convenient to data statistics and analysis.Through this measurement circuit plate whole technology, the processing procedure ability of wiring board production played supervisory function bit; Problem in the processing procedure is reflected with improving at any time; Need not each client on production board, set up test pieces; Or scrap the production plate because of test, and practiced thrift material cost, also be beneficial to the statistical analysis that detects data simultaneously.
The above; It only is the preferred embodiment of the utility model; Be not that the technical scope of the utility model is done any restriction; So every technical spirit according to the utility model all still belongs in the scope of the utility model technical scheme any trickle modification, equivalent variations and modification that above embodiment did.
