Abstract
The utility model relates to a kind of test machine signal wire switching device, comprise measuring head (1), RF signal wire (4) and the test motherboard (2) be installed on successively from bottom to top on measuring head (1) and test daughter board (3), measuring head (1) surface peripheral described test motherboard (2) offers groove (5), it is characterized in that being stamped card extender (6) in described groove (5) top, signal wire connector (7) is fixed with in described card extender (6) upper interting, the two ends of described RF signal wire are connected with the board of test machine inside with test DUT board (8) respectively, middle connected by connector (7).The utility model expands the spacing between RF signal wire, improves dismounting and changes engine efficiency, reduces spoilage and the misconnection rate of RF signal wire simultaneously, improves test accuracy rate.
Description
Technical field
The present invention relates to a kind of test machine signal wire switching device, for carrying out input to semiconductor package.Belong to technical field of semiconductor encapsulation.
Background technology
In the measuring head of existing T2000 test machine, RF signal wire is finally drawn out to test DUT board by test motherboard, test daughter board, see Fig. 1, namely path is divided into three sections: " measuring head---test motherboard ", " test motherboard---test daughter board ", " test daughter board---test DUT board ".
This kind of Wiring method shortcoming has:
One, test daughter board layout too compact, between RF signal wire, spacing is too small, reduces dismounting efficiency.
Two, test daughter board underlying space too small, RF signal wire repeatedly bends can damage by space constraint.
First motherboard must be pulled down when three, changing machine, then rearrange the RF line on daughter board according to Production requirement, reduce and change engine efficiency.
Four, test on daughter board and there is no the clearly mark of RF signal wire title (the RF signal wire of board inside extraction has 32), wrong line can be caused.
Summary of the invention
The object of the invention is to overcome above-mentioned deficiency, a kind of test machine signal wire switching device is provided, expand the spacing between RF signal wire, improve dismounting and change engine efficiency, reduce spoilage and the misconnection rate of RF signal wire simultaneously, improve test accuracy rate.
The object of the present invention is achieved like this: a kind of test machine signal wire switching device, comprise measuring head, RF signal wire and the test motherboard be installed on successively on measuring head and test daughter board from bottom to top, groove is offered on the measuring head surface of described test motherboard periphery, it is characterized in that being stamped card extender above described groove, described card extender interts and is fixed with signal wire connector, the two ends of described RF signal wire are connected with the board of test machine inside with test DUT board respectively, middle connected by connector.
Described RF signal wire is divided into two sections, and wherein one end of one section is connected with the board of test machine inside, and the other end is connected with the lower end of connector, and one end of another section of RF signal wire is connected with test DUT board, and the other end is connected with the upper end of connector.
Compared with prior art, the present invention has following beneficial effect:
1, by self-control card extender, make layout well-to-do, RF signal wire disassembling operations is convenient;
2, because RF signal wire is inner without test motherboard, be not squeezed by space constraint, RF signal wire is not easy to damage simultaneously;
3, because not needing dismounting motherboard when changing machine, making to change engine efficiency and promoting;
4, connection times reduces, and the probability of wrong line reduces greatly.

Embodiment
See Fig. 2-Fig. 3, the present invention relates to a kind of test machine signal wire switching device, comprise measuring head 1, test motherboard 2, test daughter board 3 and RF signal wire 4, described test motherboard 2 is installed on measuring head 1 upper surface, described test daughter board 3 is installed on test motherboard 2 upper surface, groove 5 is offered on measuring head 1 surface of described test motherboard 2 periphery, card extender 6 is stamped above described groove 5, described card extender 6 is fixed by fixed screw and measuring head 1, described card extender 6 interts and is fixed with signal wire connector 7, described RF signal wire 4 is divided into two sections, wherein one end of one section is connected with the board of test machine inside, the other end is connected with the lower end of connector 7, one end of another section of RF signal wire 4 is connected with test DUT board 8, the other end is connected with the upper end of connector 7, make RF signal wire be drawn out to test DUT board extraction path and be reduced to two sections, reduce RF signal wire to damage because path is complicated, increase clear and definite title to each root RF signal wire simultaneously.
This switching device is used to connect the Wiring method of RF signal wire:
1, first wife's baffle plate at measuring head upper surface grooves on two sides place is removed.
2, inner for measuring head 32 RF signal wires are removed from test motherboard, and quote to groove.
3, connect corresponding with self-control 32, card extender back side connector for 32 RF signal wires, signal wire title connects with card extender RF mouth title one_to_one corresponding.
4, use fixed screw that self-control card extender is fixed on groove.
5, RF signal wire is used to be connected by " test DUT board " connector with self-control card extender front.
