Description
Technical field
The utility model relates to a kind of test needle-bar, especially relates to a kind of test needle-bar for circuit board, belongs to electronic product test equipment designs manufacturing technology field.
Background technology
Along with popularizing of electronic product, the application product of various electronic technology becomes increasingly complex, test position, test event are more and more, in the test technology of present stage electronic product manufacturer, a large amount of employing ICT/FCT needle-bar test, in these tests, needle-bar test line is complicated, and anatomical connectivity is fragile, and high-frequency signal influences each other larger.And the differentiation of customer demand causes like product size, profile variation increasing, manufacture and require that various needle-bar is tested while meeting product test demand, accomplish rapid batch manufacture, high reliability, easy to maintenance.This just has higher requirement to existing needle-bar testing apparatus, to meet the ever-increasing requirement of existing customer.
Utility model content
Technical problem to be solved in the utility model is: provide a kind of structure simple, the test needle-bar for circuit board easy to use.
For solving the problems of the technologies described above adopted technical scheme be: a kind of test needle-bar for circuit board, comprise probe, described test needle-bar also comprises printed circuit board (PCB) and fixed sturcture, and described printed circuit board (PCB) is provided with the detecting pinhole adapted with the grafting pin hole of tested circuit board; Be plugged on the probe in described detecting pinhole, weld on described printed circuit board (PCB) by one end; In the test process of circuit board, described probe is supported by described fixed sturcture, fixing and spacing.
The beneficial effects of the utility model are: by arranging a set of test needle-bar including printed circuit board (PCB) and fixed sturcture, and the detecting pinhole adapted with the grafting pin hole on tested circuit board is set on described printed circuit board (PCB), then one end soldered probe on the printed circuit board based on detecting pinhole to be supported by described fixed sturcture, spacing and fixing.Like this, when tested board production complete need test time, can directly by tested circuit board by the grafting pin hole on it with consolidate the probe welded on the printed circuit board and be communicated with and can test, easy to use, between structure singly.When another kind of circuit board tested by needs, only again change one piece of printed panel and fixed sturcture adapted with it, rapid batch manufacture, high reliability, easy to maintenance can be accomplished.
Further, described fixed sturcture is the insulated substrate being provided with pin hole, and the position of described pin hole on described insulated substrate adapts with the grafting pin hole on the circuit board needing to test.
Further, described test needle-bar also comprises shielding separation layer, and described shielding separation layer is arranged in the circuit board side near needs test of described printed circuit board (PCB).
The optimal way of such scheme is, described shielding separation layer at least three layers.
Further, described insulated substrate is also provided with the fast combination hub of standard be communicated with described printed circuit board (PCB).
Accompanying drawing explanation
