Abstract

The utility model discloses a kind of FPC with the test of thin finger, FPC includes FPC, golden finger is provided with FPC connection ends, it is necessary to which the golden finger of test stretches out to form the outer test point of plate, and the outer test point of plate forms path with corresponding FPC internal pads.The utility model changes FPC self structures, can reduce tool cost, is adapted to each FPC to make manufacturer, on the basis of the common small cost of tool is increased, reaches Micro-probe tool test effect, completes FPC networks and all test.

Description

A kind of FPC with the test of thin finger

Technical field

The utility model discloses a kind of FPC, particularly a kind of FPC with the test of thin finger, category In FPC technical fields.

Background technology

With the continuous development of electronic technology, the species of electronic component is also increasingly abundanter, and wiring board is also already broken through The limitation of traditional pcb board, and use FPC, also referred to as FPC in many occasions and field.FPC is in group , it is necessary to test it before loading product, and as circuit board line designs more and more finer, line interface（It is also referred to as golden Finger）The detection at place is also more and more difficult, especially pressure screen class product（The FPC being connected with display screen）, golden finger quantity is non- Chang Duo, and line style is thinner, the distance between adjacent golden finger is shorter, and detection difficulty is very high, and conventional needle presses screen class thin for FPC Finger（Thinner golden finger is referred to as thin finger in the utility model）Test mode have the following two kinds：（1）, use conduction Glue, tested using standard-sized sheet/dead-short-circuit mode, blind area is relatively more, can not ensure full non-defective unit for product quality；（2）Design is special Micro-probe tool is tested, and tool finished product is high.

The content of the invention

For the thin finger detection difficulty on FPC of the prior art mentioned above it is higher the shortcomings that, the utility model A kind of FPC with the test of thin finger is provided, it is by the way of individually drawing outside test point to FPC plates, so as to open Common tool is tested, and realizes the cost of the tool reduced while product full non-defective unit.

The utility model solves the technical scheme that its technical problem uses：A kind of flexible circuitry with the test of thin finger Plate, FPC include FPC, are provided with golden finger at FPC connection ends, it is necessary to which the golden finger of test stretches out to form plate exterior measuring Pilot, the outer test point of plate form path with corresponding FPC internal pads.

The technical scheme that the utility model solves the use of its technical problem further comprises：

The outer test point of described plate is in water-drop-shaped, and tip is connected with golden finger.

The outer test point of described plate is in multi-row staggered setting.

Described FPC connection ends stretch out to form garbage area, stretch out to form the outer test point of plate at garbage area.

The beneficial effects of the utility model are：The utility model changes FPC self structures, can reduce tool cost, fits Close each FPC and make manufacturer, on the basis of the common small cost of tool is increased, reach Micro-probe tool test effect, complete FPC nets Network is all tested.

The utility model is described further below in conjunction with the drawings and specific embodiments.

Brief description of the drawings

Fig. 1 is the utility model structure diagram.

Fig. 2 is Fig. 1 A partial enlargement structural representations.

Fig. 3 is Fig. 1 B partial enlargement structural representations.

In figure, 1-FPC, 2- garbage areas, the outer test point of 3- plates, 4- internal pads, 5-FPC trim lines, 6- golden fingers.

Embodiment

The present embodiment is the utility model preferred embodiment, and other all its principle and basic structure are identical with the present embodiment Or it is approximate, within scope of protection of the utility model.

Accompanying drawing 1, accompanying drawing 2 and accompanying drawing 3 are refer to, the utility model main body is FPC1, and golden finger is provided with FPC1 connection ends 6, stretch out to form test point 3 outside plate on the golden finger 6 for needing to test, the outer test point 3 and FPC1 of the plate shape of internal pads 4 Into path, be easy to detect, in the present embodiment, the outer test point 3 of plate be in water-drop-shaped, sophisticated to be connected with golden finger 6, test area compared with Greatly, it is similar with the pad of routine, it is easy to test using conventionally test tool, the outer test point 3 of plate can be in multi-row staggered setting, this reality Apply in example, by taking two rows as an example, the outer test point 3 of the plate on a golden finger separately row located above, on other golden fingers The outer test point 3 of plate is located below a row, using the form of being staggered, the outer area of test point 3 of plate can be made to do bigger, Detection results More preferably, when it is implemented, three rows or more can also be set to arrange.In the present embodiment, FPC1 is more square in order to process in processing Just, it will usually which stretch out certain distance in the outside of FPC trim lines 5 of FPC1 connection ends, and forms certain garbage area 2, plate Outer test point 3 continues to stretch out to be formed at garbage area 2, in use, test point 3 outside 2 related plate of garbage area is cut off together, Its normal use is not interfered with.

Test point 3 is pulled in garbage area 2 by the utility model, is tested by the kind testing needle mode of routine, among FPC Pad 4 forms loop by test machine, whether correct can test out network.

The utility model changes FPC self structures, can reduce tool cost, is adapted to each FPC to make manufacturer, general increasing On the basis of the small cost of logical tool, reach Micro-probe tool test effect, complete FPC networks and all test.
