Description

A kind of test DUT board
Technical field
The utility model relates to a kind of test DUT board, belongs to semiconductor test technical field.
Background technology
Semiconductor reliability test is one important procedure in semiconductor manufacturing, its objective is that whether the semiconductor device electrical property detecting manufacture is qualified, thus weeds out underproof product.When carrying out semiconductor reliability test, first testing sample (normally through the chip of simplified package) is inserted into DUT (device under test, DUT) on plate, again DUT board is received on tester table, corresponding test data is obtained by the test of tester table, as can be seen here, the quality of DUT board quality directly has influence on the test result of semiconductor reliability test.
Existing DUT board needs manual work welding lead when making; human weld's circuit often can cause empty short void to break; thus cause testing FAIL; a lot of resistance is used in addition because existing DUT board makes needs; along with the time one is long; the aging meeting of DUT board causes the problem of the higher or loose contact of contact resistance, thus impact test, affect the serviceable life of DUT board.And, existing DUT board be the MUX relay of test machine inside, service time has been grown, the convert resistance of relay easily increases, and uses internal relay, and measurement circuit can be very long, easily cause the change of external interference and line impedance, thus cause test unstable.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned deficiency, provides a kind of making simple, reliable and stable, the test DUT board that service efficiency is high, adaptive is strong.
The purpose of this utility model is achieved in that a kind of test DUT board, it comprises printed circuit board (PCB), side, described printed circuit board (PCB) front is provided with multiple golden finger, described printed circuit board (PCB) front opposite side is horizontally arranged with a cattle horn socket, a Noguchi socket is vertically provided with between described multiple golden finger and cattle horn socket, relay is provided with between described Noguchi socket and cattle horn socket, described printed circuit board (PCB) front is provided with resistance, described multiple golden finger is connected with the joint of cattle horn socket with Noguchi socket respectively by printed circuit board wiring, described relay is connected with Noguchi receptacle terminal respectively by printed circuit board wiring with resistance.
Compared with prior art, the utility model has following beneficial effect:
1, this DUT board directly by traverse design in the printed circuit boards, saves the process of human weld's wire, avoids the wire bonds loosely problem because artificial bonding wire produces, thus impact is electrically connected, product test result;
2, the circuit of this DUT board all designs in the printed circuit boards, and surface has green varnished insulation layer to protect, so this DUT board long service life, there will not be the improper wire short circuit that causes of the manual operation because wire exposes or open circuit problem;
3, the circuit flexible design of this DUT board is in the printed circuit boards, so this DUT board suitability is stronger, and can by the test realizing different product of the different Noguchi sockets in printed circuit board (PCB);
4, this DUT board uses outside relay, shortens measurement circuit, reduces line impedance and external interference, thus makes stable testing reliable;
5, this DUT board uses simple to operate, only needs to install golden finger during use before DUT board, reduces debug time, improves testing efficiency.
Accompanying drawing explanation
fig. 1 is a kind of structural representation testing DUT board of the utility model.
Wherein:
Printed circuit board (PCB) 1
Golden finger 2
Noguchi socket 3
Cattle horn socket 4
Relay 5
Resistance 6.
Embodiment
See Fig. 1, the utility model one test DUT board, it comprises printed circuit board (PCB) 1, side, described printed circuit board (PCB) 1 front is provided with multiple golden finger 2, described printed circuit board (PCB) 1 front opposite side is horizontally arranged with a cattle horn socket 4, a Noguchi socket 3 is vertically provided with between described multiple golden finger 2 and cattle horn socket 4, relay 5 is provided with between described Noguchi socket 3 and cattle horn socket 4, described printed circuit board (PCB) 1 front is provided with resistance 6, described resistance 6 is positioned at below cattle horn socket 4, described multiple golden finger 2 is connected up by printed circuit board (PCB) 1 and is connected with the joint of Noguchi socket 3 with cattle horn socket 4 respectively, described relay 5 is connected with Noguchi socket 3 joint respectively by printed circuit board (PCB) 1 wiring with resistance 6.
During detection, cattle horn socket is connected with the motherboard of test machine by winding displacement, and golden finger is connected with Test handler, can test.
