Mode.
An embodiment of the present utility model is a kind of false pressure test FPC, for the false pressure test of functional glass, the function
There are some pins on glass.Vacation pressure test FPC includes base material, some golden fingers and conductive shaft；Between some golden fingers
Golden finger array is formed on the substrate every setting, it is described for being corresponded with each pin on the functional glass
Conductive shaft is between the golden finger array and the pin, and the conductive shaft electrically connects with the base material.That is, with whole
Golden finger is as a golden finger entirety, i.e. golden finger array, using whole pins as a pin entirety, the conductive axle position
Between golden finger entirety and pin entirety.
Above-mentioned false pressure test FPC, by setting conductive shaft electrically connect with base material, make to work as the two neighboring golden finger of test it
Between capacitance and during the circuit of preliminary arbitration functions glass the problems such as there may be open circuit, then pass through testing conductive axle and golden hand
Resistance value between finger and determine whether the quality of the circuit of functional glass, reduce probability of miscarriage of justice, improve false pressure test FPC's
Testing reliability.
It should be noted that generally FPC also includes being covered in the copper foil on the surface of base material, is covered on copper foil and does not cover
Cover layer on golden finger, will not be repeated here.
For example, refer to Fig. 2 and Fig. 3, a kind of false pressure test FPC 30, including base material 310, some golden fingers 320 and lead
Electric axis 330.
Some golden fingers 320 are disposed on formation golden finger array on base material 310.For example, each golden finger 320 is mutual
It is arranged in parallel.For example, one end of golden finger array is set close to the edge of base material side.So, false pressure test FPC presses to work(
When on energy glass, the area of vacation pressure test FPC covering function glass is smaller, relatively holds terminating to test when needs are taken off from functional glass
Easily.
Conductive shaft 330 is arranged between golden finger 320 and the pin 410 of functional glass 400, and conductive shaft 330 and base material
310 electrical connections.For example, conductive shaft 310 is vertical with golden finger array and non-intersect setting.So, more can guarantee that conductive shaft 330 with
More pin 410 contacts on functional glass 400.For example, golden finger 320 is adjacent to one end of conductive shaft 330 and conductive shaft 330
Distance is less than the length of the pin 410 on functional glass 400.So, it can guarantee that the pin 410 on functional glass 400 leaves one
Fixed position, contacted so as to be advantageous to pin 410 with conductive shaft 330.For example, golden finger 320 adjacent to one end of conductive shaft 330 with
The distance of conductive shaft 330 is the half of the length of pin 410.In another example golden finger 320 is adjacent to one end of conductive shaft 330
Distance with conductive shaft 330 is 1/3rd of the length of pin 410.
For example, the material of conductive shaft is copper.For example, conductive shaft is a copper rod.For example, conductive shaft is cylindrical shape, for example,
Conductive shaft is rectangular-shape.For example, conductive shaft is arranged on outside base material, and conductive shaft is electrically connected by wire with base material.So, lead
Electric axis is convenient for changing, and is also convenient for making in addition.For example, conductive shaft is arranged on base material.So, position of the conductive shaft on base material
It is fixed, fixed with the relative position of golden finger array, only need to be by the pin pair on golden finger array and functional glass in contraposition
Position, conductive shaft no longer need to align with functional glass in addition.
In order that the pin contraposition that false pressure is tested on golden finger and functional glass on FPC is accurate, for example, referring to
Fig. 2, alignment mark portion 301 is additionally provided with base material.So, more accurately test FPC can be pressed to be made with functional glass vacation
Vacation pressure contraposition processing.For example, the quantity in the alignment mark portion 301 is two, described two alignment mark portions 301 are set respectively
In the both sides of the golden finger array.So, soft false pressure can be tested into FPC by being arranged on the alignment mark 301 of both sides
Stretch, and all more accurately aligned in the both sides of golden finger 320.For example, the alignment mark portion 301 is T fonts.This
Sample, by setting the extended line in three directions to improve aligning accuracy.For example, the alignment mark portion 301 is Y-shaped.So,
By setting three extended lines not on one wire more to improve aligning accuracy.For example, the alignment mark portion 301 is
Cross.So, by setting the extended line of four direction further to improve aligning accuracy.
Carry out circuit quality in test function glass using the false pressure test FPC of the utility model embodiment, first, using biography
The testing scheme of system, press the pin tested on golden finger and functional glass on FPC to correspond pressing by false, then test phase
Capacitance between adjacent two golden fingers, when the capacitance of test is not 0, the circuit of decision-making function glass is intact, terminates to survey
Examination；When the capacitance of test is 0, further test.Referring to Fig. 3, for example, when the capacitance C (A, B) of test is 0
When, further test.Some pins on conductive shaft and functional glass are pressed, and the electricity between testing conductive axle and golden finger
Resistance R (Z, A), the resistance value between testing conductive axle and golden finger.If test result is 0, judge that false pressure is reliable, problem is just
On glass, result of determination is damaged for the circuit of functional glass, terminates test；If test result is infinity, result of determination
It is that false pressure test is unreliable, false pressure test need to be re-started and sentenced again.So, by such scheme, can just exclude because vacation pressure is asked
The erroneous judgement of product caused by topic, probability of miscarriage of justice is reduced, improve false pressure test FPC testing reliability.It should be noted that false pressure
Test FPC is operated as a part for FPC measurement jigs by concrete operations FPC measurement jigs.In general, FPC are controlled
Tool also includes base, overlap joint line, stopper slot and pressing part on base；Test board, vacation pressure test FPC are provided with base
It is connected and is stretched into stopper slot with test board and is used to be connected with functional glass to be measured；Overlap joint line be located in stopper slot for etc. it is to be measured
Functional glass overlaps；The shape and depth of stopper slot are consistent with functional glass to be measured；Pressing part carries pressure head, and pressure head, which is located at, to be taken
The top of wiring, and pressing part can move up and down with dynamic head.
Each technical characteristic of embodiment described above can be combined arbitrarily, to make description succinct, not to above-mentioned reality
Apply all possible combination of each technical characteristic in example to be all described, as long as however, the combination of these technical characteristics is not deposited
In contradiction, the scope that this specification is recorded all is considered to be.
Embodiment described above only expresses several embodiments of the present utility model, and its description is more specific and detailed,
But therefore it can not be interpreted as the limitation to utility model patent scope.It should be pointed out that the common skill for this area
For art personnel, without departing from the concept of the premise utility, various modifications and improvements can be made, these are belonged to
The scope of protection of the utility model.Therefore, the protection domain of the utility model patent should be determined by the appended claims.
