Abstract
The utility model relates to a composite type test device of a printed circuit board. The utility model is provided with a testing machine table on which corresponding bases are arranged. The bases are provided with probes which are connected to the testing machine table. Corresponding converting boards are respectively arranged between the bases. Testing salient points and needle testing points are arranged on the converting boards, wherein the salient testing points correspond to a printed circuit board to be tested and the needle testing points are respectively correspond to the probes. The surfaces of the converting boards are covered by conductive rubber cloth (PCR-Pressure Contact Rubber). As a result, the needle testing points arranged on the printed circuit board contact the salient points arranged on the converting boards through the conductive rubber cloth at the testing time, and then, the converting boards contact the probes arranged on the base; thereby, the testing work can be carried out and probes of special specifications are not required. The utility model has the advantages of breakthrough of the limitation of the testing area and the testing points, cost saving and no needle points left on the printed circuit board to be tested.
Description
Technical field
The utility model is a kind of composite printed circuit board proving installation, especially refer to a kind of combining of tailored version (Dedicate) device and conducting adhesive cloth type device (hereinafter to be referred as PCR type device) of utilizing, and utilize the tailored version test machine to test, and on device, substitute the existing employed probe of tailored version test machine proving installation by conducting adhesive cloth and salient point, and can avoid the damage of probe, and stay pin mark at printed circuit board (PCB) to be measured, more can break through the restriction of test area and number of test points, installation cost also significantly reduces relatively.
Background technology
Existing printed circuit board (PCB) (PCB, printed circuit board) is after making, and whether still need through trace routine is non-defective unit to detect this printed circuit board circuitry; And the pick-up unit that general printed circuit board (PCB) manufacturer is adopted, can generally be divided into tailored version (Dedicate) test machine, general-using type (Universal) test machine and PCR type test machine etc., wherein, the tailored version test machine, please refer to shown in Figure 1, it mainly is provided with relative stacker on test machine, be respectively equipped with device on the described stacker, be respectively equipped with probe on the described device, this kind test machine is cheap and test speed is fast, but installs expensively, and especially the used elastic probe of accurate circuit is quite accurate and expensive on the fit printed circuit board, and damage easily and often need to change, cause the increase of testing cost;
Otherwise the general-using type test machine then is the machine costliness, but the comparable general minute hand device of its used probe is cheap; When so general favourable operating position ties up to the detection of printed circuit board (PCB) sample, select the general-using type test machine earlier for use, treat the checking of this printed circuit board (PCB) by and will begin volume production the time, then use the tailored version test machine instead meeting the mass production needs, only still to exist the expensive and accurate elastic probe unit price of device high and often need to eliminate shortcoming such as renewal again for the tailored version test machine.
Comprehensive above as can be known said, tradition is carried out printed circuit board test with Dedicate device, PCR type device, precisely because shortcoming is as follows:
1 isolated plant kenel cost is higher, though can test the higher circuit board of difficulty, the use amount of its pin and cost allow the cost of this device high really.
2.PCR its test no needle mark of type device kenel, for all needle devices can't be accomplished, its testable difficulty has beaten by miles above-mentioned, but the restriction of its test area and number of test points much can't use in a large number, and the costing an arm and a leg of its test machine.
Make part at above-mentioned shortcoming dealer and improved creation, include the TaiWan, China patent announcement and number " change-over panel of PCB tailored version test machine and general-using type test machine device " novel patent of No. 367961, reach the TaiWan, China patent announcement and number " improvement of composite device probe structure " novel patent No. 378756, but still following shortcoming is arranged.
Above-mentioned composite device kenel in conjunction with tailored version test machine and general-using type test machine device, though lower many than the cost of tailored version device, the pin trace of test is insurmountable problem, and is relatively also complicated many in problem eliminating and making.
Summary of the invention
Creator of the present utility model is because the shortcoming of above-mentioned existing apparatus, therefore be at its very crux, take up to be sought to improve, mending it lacks, in the hope of seeking a reasonable solution, analyse, design through grinding many times, finish composite printed circuit board proving installation of the present utility model finally.
The purpose of this utility model is achieved in that a kind of composite printed circuit board proving installation, mainly includes: a pedestal, and itself and test machine join, and this pedestal is provided with more than one probe, and described probe is arranged on the assigned address with the need; One change-over panel, it is seated on the pedestal, this change-over panel one side is provided with salient point, the position of described salient point and number change with printed circuit board (PCB) to be measured, this change-over panel another side then is provided with the pin measuring point, described pin measuring point is connected with corresponding salient point by the electrical communication circuit, and described pin measuring point is relative with the probe that cooperates respectively; One conducting adhesive cloth, it covers on the face that change-over panel has salient point; By forming of above-mentioned member, when order is tested, pin measuring point on the printed circuit board (PCB) can see through conducting adhesive cloth and contact with salient point on the change-over panel, contact with probe on the pedestal by change-over panel again, the so work that can test, and need not use the probe of special specification, and can break through the restriction of test area and number of test points, more can on printed circuit board (PCB) to be measured, not stay pin mark.
And composite printed circuit board proving installation described in the utility model, it is provided with relative pedestal, described pedestal is provided with the probe that is connected with the tailored version test machine, between described pedestal, then be respectively equipped with relative change-over panel, described change-over panel be provided with the corresponding testing bump of printed circuit board (PCB) to be measured and respectively with the corresponding pin measuring point of probe, and described change-over panel is coated with conducting adhesive cloth on the surface, and when test, can substitute the existing employed probe of tailored version test machine proving installation by conducting adhesive cloth and salient point, and can avoid the damage of probe, and stay pin mark at printed circuit board (PCB) to be measured, more can break through the restriction of test area and number of test points, installation cost also significantly reduces relatively.
