Abstract
The utility model relates to a chip gold wire detection tool clamp which comprises two clamp seats, wherein a bearing is respectively arranged in each clamp seat from top to bottom; by adopting the scheme, the sample chip can rotate 360 degrees, the gold wires to be measured can be rotated to the forward direction for measurement, multi-dimensional measurement is realized, strong magnet adsorption is added on the rotating shaft, and the damage of the gold wire chip caused by the collapse of the gold wires in the product measurement process is prevented.
Description
Technical Field
The utility model relates TO the field of TO packaged chips.
Background
The TO encapsulation needs TO be measured the excessive line arc that glues and the gold wire of chip glue, and current measurement mode mainly is suitable for and distributes on a horizontal plane at the gold wire, and the gold wire can be the multi-angle when the chip has a plurality of pins and distributes, and the deviation will appear in the gold wire measurement on a front not, and during the adjustment was measured, current measurement technology management and control actual operation not only is complicated still can be surveyed inaccurately, easily causes the chip damage or the gold wire TO collapse when advancing the direction of rotation measurement.
SUMMERY OF THE UTILITY MODEL
The utility model aims to provide a chip gold wire detection clamp which can perform multi-dimensional measurement and is accurate in measurement.
In order to achieve the above object, the present invention provides a chip gold wire detection tooling fixture, which comprises two fixture seats, wherein the fixture seats are provided with a bearing respectively at the upper and lower parts, the bearing is sleeved with a rotating shaft, the middle part of the rotating shaft is provided with an annular rotating handle, one fixture seat is provided with an opening part for accommodating the annular rotating handle, the rotating shaft is hollow, a pin of a sample chip can be extended therein, and the upper end surface of the rotating shaft is provided with a concave chip placing table.
The lower end face of the rotating shaft is provided with a strong magnet.
By adopting the scheme, the sample chip can rotate 360 degrees, the gold wires to be measured can be rotated to the forward direction for measurement, multi-dimensional measurement is realized, strong magnet adsorption is added on the rotating shaft, and the damage of the gold wire chip caused by the collapse of the gold wires in the product measurement process is prevented.
Drawings

Description of reference numerals:
1. a clamp rear sheet; 2. clamping the front piece; 21. an opening part; 3. a bearing; 4. a rotating shaft; 41. a chip placement table; 5. a shaped turning handle; 6. a strong magnet; 7. a sample chip; 71 chip pins.
Detailed Description
In order to explain technical contents, structural features, and objects and effects of the present invention in detail, the following detailed description is given with reference to the accompanying drawings in conjunction with the embodiments.
Referring to fig. 1 and 2, the chip gold wire detection tool fixture of the present invention is used for installing a sample chip on a fixture to perform glue overflow and gold wire arc measurement on the sample chip, the front and rear pieces of the fixture can be paired with fixture seats, the fixture seats mainly comprise a fixture rear piece 1, a fixture front piece 2 and a rotating shaft 4 arranged in the fixture rear piece, the rotating shaft 4 is respectively sleeved with a bearing 3 up and down, the bearing 3 is arranged in a cavity between the fixture rear piece 1 and the fixture front piece 2, the middle part of the rotating shaft 4 is sleeved with an annular rotating handle 5, and the fixture front piece 2 is provided with an opening 21 for accommodating the annular rotating handle 5. The rotating shaft 4 is arranged in a hollow manner, the pins 71 of the sample chips 7 can be extended into the hollow rotating shaft, the upper end face of the rotating shaft 4 is provided with a concave chip placing table 41, and the edge of the chip placing table 41 can be provided with a plurality of notches, so that the sample chips 7 can be conveniently taken out of the chip placing table 41. The lower end of the rotating shaft 4 is provided with the strong magnet 6 which is adsorbed, so that the damage of a gold wire collapse chip caused by falling in the product measuring process is prevented.
When the utility model is used for measurement, a sample chip 7 is placed on the chip placing table 41, the annular rotating handle 5 is rotated, the gold wire to be measured is rotated to be over against the measuring device for measurement, and if the next gold wire is measured, the annular rotating handle 5 is continuously rotated.
The above description is only an embodiment of the present invention, and not intended to limit the scope of the present invention, and all equivalent changes in shape and structure made by using the contents of the present specification and drawings, or applied directly or indirectly to other related technical fields are included in the scope of the present invention.
