Embodiment 1

[0043] like Figure 1-5 As shown, this embodiment takes a 4×4 free-space two-dimensional array detector as an example for illustration:

[0044] The detector chip 2 in this embodiment is a 4×4 two-dimensional array detector chip, and the detector chip 2 is rectangular.

[0045] The detector chip 2 includes 20 bonding pads, including 16 positive electrode bonding pads and 4 negative electrode bonding pads.

[0046] The heat sink 4 is rectangular.

[0047] There are 18 conductive contacts 41 on the heat sink 4 . The conductive contacts 41 are distributed on the four sides of the rectangle, and the conductive contacts 41 are symmetrical to the central axis of the rectangle (including the central axis connecting the central points of the long sides and the central axis connecting the central points of the short sides). Specifically, four conductive contacts 41 are provided on the long side, three conductive contacts 41 are provided on the short side, and one conductive contact ...

Embodiment 2

[0053] like Figure 6-10 As shown, this embodiment takes a 3×3 free-space two-dimensional array detector as an example for illustration:

[0054] The detector chip 2 in this embodiment is a 3×3 two-dimensional array detector chip, and the detector chip 2 is square. The detector chip 2 includes 9 positive pads and 3 negative pads.

[0055] The heat sink 4 is a square.

[0056] There are 12 conductive contacts 41 corresponding to the 12 pads on the detector chip 2 . The conductive contacts 41 are distributed on the edges of the square, and three conductive contacts are arranged on each side of the square.

[0057]The pins of the detector chip 2 are evenly distributed on the four sides of the first square, the conductive contacts 41 are evenly distributed on the four sides of the second square, and the pins 31 are evenly distributed on the four sides of the third square. , the centers of the second square and the third square are the same and the four sides of the first squar...

Embodiment 3

[0059] like Figure 11 As shown, this embodiment takes another pin arrangement form of a 3×3 free-space two-dimensional array detector as an example for illustration:

[0060] The pins of the detector chip 2 are evenly distributed on the first circle, the conductive contacts 41 are evenly distributed on the second circle, and the pins 31 are evenly distributed on the third circle. The first circle, the second circle and the third circle are concentric circles.

[0061] The heat sink 4 is circular, and the heat sink 4 is concentric with the first circle.

Abstract

The invention relates to a free space two-dimensional array detector which comprises a tube socket, a heat sink and a detector chip, the heat sink is located on the tube socket, the detector chip is located on the heat sink, the heat sink is provided with a conductive contact, a pin of the detector chip is connected with the conductive contact through a wire, and the conductive contact is connected with the pin through a wire. Therefore, the problem that the wire is too long and short-circuited easily can be avoided, and the reliability of the product is improved.

Description

technical field [0001] The invention relates to the technical field of free-space light detection, in particular to a free-space two-dimensional array detector. Background technique [0002] Free-space two-dimensional array detectors are more and more widely used. Free-space two-dimensional array detectors generally include a tube base, pins on the tube base, and a detector chip. [0003] The pins of the detector chip of the existing free-space two-dimensional array detector are generally directly connected to the pins through wires. [0004] Due to the large number of pins, the large area and the small size of the detector, the pins and pins of the detector chip are directly connected by wires. On the one hand, there will be a problem that the wires are too long. On the other hand, the wires are easily short-circuited. affect product reliability. Contents of the invention [0005] The invention provides a free-space two-dimensional array detector, which solves the techn...
