Description
Technical field
The utility model belongs to Drive Test jig field more particularly to a kind of high-precision contact mechanism for testing, especially but
It is not limited to the ICT tests of ultrathin flexible circuit board.
Background technology
Flexible PCB is that have height reliability as one kind made of base material using polyimides or polyester film, excellent
Flexible printed circuit has the characteristics that Distribution density is high, light-weight, thickness is thin, bending is good.
In production flexibility circuit boards, in order to ensure that produced flexible PCB is qualified, need to each
Flexible PCB is tested, including to flexible PCB（FPC）Product open circuit, short circuit, capacitance, resistance, inductance and switch etc.
Original paper is tested.It is to adjust manually by artificial blowing, pass through jig to be primarily now used for testing flexible PCB Drive Test jig
Display screen above adjusts micrometer to realize product aligning.This test method not only expends the time, but also also is difficult to ensure
The reliability that product measures.Also, the DT jigs of flexible circuit board test are currently used primarily in, are mostly by adjusting survey manually
Examination, has a great impact to the precision of test, also expends long time, even automatic measurement jig, also fail to offer one
Kind is only applicable to general flexible circuit board test the fixation test method of ultrathin flexible circuit board, if for high-precision
Close, ultrathin flexible circuit board testing, aligning accuracy it is difficult to ensure that.
In addition, existing ICT measurement jigs can only measure thicker larger flexible PCB, and at this stage, flexible circuit

It is not particularly suited for the test of the FPC strips of some reflective materials, positive polishing is since light source dissipates, for reflective material,
Test can influence CCD and capture precision.According to the mechanism of optically focused, just it is unfavorable for the test of product.
Therefore, the above problem is urgently to be resolved hurrily.
The prior art provides a kind of Drive Test jig, provides a kind of pneumatic clamping FPC plates in that patent and carries out pair
Position.Contact to PIN points on FPC plates is by being equally that golden finger contact measures, and is base compared to probe-type test advantage
Golden finger weighs problem wounded in this detection circuit board, and probe is easy to weigh the PIN points of product wounded, may cause to connect by point contact
Touch undesirable scene.The difference of the application and it：1. after the application is using product is placed, automatic absorbing product need not be artificial
Manual depression, it is directly automatic to push.2. the test of product PIN point contacts by probe, is not turned by direct with another FPC
Fishplate bar PIN point contacts realize test.The advantages of the application, is that can fast implement automatic aligning tests, and qualification rate carries significantly
Height improves work efficiency.
The prior art additionally provides an ICT measurement jig.However it is with following defect：1. it catches using CCD
Positive polishing is caught, this effect is only applicable to the FPC plates without reflective material, can sound equipment CCD catching positions if material is reflective
Precision, this application provides a kind of completely new structures by back side polishing, can solve the above problems.2. automatic used by it
Alignment mode is to move to realize that automatic aligning is captured by CCD modules, and the application realizes 0.005mm using mobile FPC pinboards
Precision finely tunes automatic aligning, and the benefit of this alignment mode can effectively improve aligning accuracy.3. its mechanism product platform deck
Be not suitable for the fixation of FPC plates small to specification, frivolous, with high accuracy.This application provides it is a kind of fix it is this ultra-thin high-accuracy
The structure of FPC plates.
