Embodiment
Below by embodiment, by reference to the accompanying drawings the present invention is described in further detail, involved technical characterictic in each embodiment of the application of the following stated just can not combine mutually as long as form each other conflict.
Please refer to Fig. 3-7, the sniffer that the present embodiment provides a kind of golden finger for circuit board to survey, this sniffer comprises card extender, survey the probe of use and other existing correlation detection parts (because the application does not relate to the improvement of other correlation detection parts, therefore in the present embodiment, do not illustrate further), this card extender 2 docks one by one with the golden finger structure on circuit board under test, probe is to dock with card extender 2, to carry out the detection to the golden finger 11 of circuit board, but not directly with the golden finger on circuit board under test, dock, can avoid causing the damage of probe to the golden finger surface.
Particularly, please refer to Fig. 3-6, surveying card extender 2 in the present embodiment can be soft board, it can be also hardboard, it has switching part 21 and extension 22, switching part 21 comprises a plurality of switching conductive contact blades 211 for docking one by one with golden finger 11 on circuit-under-test plate 1, the structure of this switching conductive contact blade 211 is corresponding one by one with the structure of tested golden finger 11, the live width of each switching conductive contact blade 211 is identical with tested golden finger 11 structures with line-spacing, minimum feature, minimum line is apart from also all consistent with tested golden finger 11, so that switching conductive contact blade 211 can dock one by one with tested golden finger 11.
This extension 22 comprises a plurality of extension points 221 for docking with exploratory probe, and extension point 221 is electrically connected to corresponding switching conductive contact blade 211.
In addition, also there is a space problem in existing detection mode simultaneously, along with the requirement of modern electronic product to volume, the requirement of walking line density of circuit board 1 is also progressively improving, the live width of conductive contact blade on golden finger 11 (PIN) 111, line-spacing are also more and more accurate, and the line-spacing of being the live width of 0.05mm and 0.05mm on current circuit board 1 is very common.But more and more less with respect to conductive contact blade 111 live widths and line-spacing, the technology of probe lags behind far away, the minimum diameter of probe at present commonly used is all more than 0.1mm, be far longer than live width and the line-spacing of conductive contact blade 111, when probe reaches on conductive contact blade 111 while being surveyed other conductive contact blades 111 around easily encountering, cause result of detection inaccurate.
Therefore in the present embodiment, also can make the spacing between extension point 221 on card extender 2 be greater than the probe external diameter docked with it, probe can extend between extension point and be surveyed easily, can not touch easily other extension points, avoid the interference of other extension points, improve the correctness that probe is surveyed.
Certainly, this switching conductive contact blade 211 and extension point 221 all adopt conducting medium to make, and wherein extension point 221 can adopt gold plated pads (PAD) or existing golden finger structure.Wherein in the present embodiment for two switching parts 21, two extensions 22 are set on card extender.
The detection of this extension point 221 can adopt two-wire system, three-wire system and four-wire system, and the quantity of the extension point 221 of collinear system is not different, specifically can be with reference to the detection mode of prior art.Take four-wire system in the present embodiment as example, because four-wire system is surveyed each conductive contact blade 111 and need be drawn two lead-in wires, so each switching conductive contact blade 211 connects two extension points 221.As adopt two-wire system, a switching conductive contact blade 211 connects an extension point.
For the ease of the location of machine, the MARK point can also be set on card extender, this MARK point is the visual identity monumented point, usually with "+" or " o " such graphical symbol, means.The visual identity monumented point has fixing size, and design is on the fixing coordinate of whole FPC usually, and the present embodiment designs 3 MARK on a FPC.At first machine vision is checked through these three MARK in the whole visual field, then calculates relative position and coordinate, with the residing mechanical coordinate of identification FPC, thereby visual coordinate and mechanical coordinate is linked together.
Please refer to Fig. 3 and 5, in order to locate fast, accurately circuit board under test, can on card extender 2, arrange some for circuit-under-test plate 1 being carried out to the keeper 23 of auxiliary positioning, this keeper 23 is a plurality of, and enclose and be formed for placing the placement position with the circuit-under-test plate of golden finger 11, this placement position is identical with the partial shape that is manufactured with golden finger 11 on circuit-under-test plate 1, in order to carry out auxiliary positioning.
This keeper 23 regioselective pins in the present embodiment, certainly, keeper 23 can also select other projections to be arranged on the parts of web joint.
Please refer to Fig. 7, for the effect that contacts between strengthen transferring conductive contact blade 211 and tested golden finger 11, guarantee that contact resistance is less, to realize better docking, this sniffer can also comprise for tested golden finger 11 being pressed on to the briquetting 3 of card extender 2, more specifically, this briquetting 3 can be block rubber or other elastic material blocks.And this briquetting 3 is in use, can be pressed on the circuit-under-test plate by self gravitation, or also briquetting can be connected with corresponding driving mechanism, by driving mechanism, drive briquetting to push down the circuit-under-test plate, this driving mechanism can be the driving mechanisms commonly used such as cylinder.
Please refer to Fig. 5 and 6, the conductive contact blade 211 of directly transferring during use docks one by one with the conductive contact blade 111 on circuit-under-test plate 1, and probe only need be surveyed extension point 221 and gets final product, without the direct tested golden finger 11 of docking again, can avoid causing the damage of probe to golden finger 11 surfaces.Be greater than the external diameter of exploratory probe due to the spacing of this extension point 221, probe can extend into easily between extension point 221 and be surveyed, and can not touch easily other extension points 221, avoids the interference of other extension points 221 simultaneously, improves the correctness that probe is surveyed.
Above content is in conjunction with concrete embodiment further description made for the present invention, can not assert that specific embodiment of the invention is confined to these explanations.For the general technical staff of the technical field of the invention, without departing from the inventive concept of the premise, can also make some simple deduction or replace.
