Abstract

A printer chip fixing device comprises a base, a gasket and a clamping cover; the middle part of the base is provided with a U-shaped groove, and two sides of the base are provided with V-shaped clamping grooves; the gasket is arranged in the U-shaped groove, and small teeth are arranged on the surface of the gasket; v-shaped buckles are arranged on two sides of the clamping cover, and a through hole is formed in the middle of the clamping cover; the V-shaped buckle is matched with the V-shaped clamping groove, and the V-shaped buckle can be buckled on the V-shaped clamping groove. The advantages are that: the chip is placed in the U-shaped groove and on the gasket, the upturned small teeth on the gasket are designed to be easily contacted with copper contacts on the back of the chip, all accessories are copper and are mutually communicated, and the whole accessory is placed on the aluminum sample table and can be communicated with the contacts on the back of the chip through all copper materials. Thus, the problem that the copper contact on the back of the chip cannot be contacted with aluminum foil paper is well solved, and the phenomenon that the chip is uneven; the utility model can be used for 15 chips at a time, and solves the problem that too many samples cannot be loaded in the prior art.

Description

Printer chip fixing device

Technical Field

The utility model belongs to the technical field of integrated circuit manufacturing, and particularly relates to a printer chip fixing device.

Background

The printer chip in the prior art is fixed, the back of the chip is punched down, aluminum foil conductive paper is padded on the lower surface of the chip, and the chip is symmetrically clamped by two aluminum metal clamps, so that 9 yellow copper contacts on the back of the chip are communicated with an aluminum sample table. The method has the following technical defects: 1) Because the 9 yellow copper contacts on the back of the chip are slightly recessed compared with the surrounding green circuit board, the aluminum foil paper is padded and is smooth in electric conduction, so that the 9 contacts on the back cannot be in perfect contact with the aluminum foil paper, and even the situation that the contacts cannot be in contact occurs; 2) Sometimes uneven pressure can occur on the clamping force of the two clamps, so that the phenomenon of uneven chip is caused; 3) Two clamps take up too much space on the sample stage, causing the problem of not being able to load too much sample at a time.

Disclosure of Invention

The utility model aims to solve the technical problems that: the printer chip fixing device overcomes the defects of the prior art, and provides a printer chip fixing device which has good contact between a chip copper contact and aluminum foil paper, has a horizontal chip surface and can be used for loading a plurality of samples at one time.

The technical scheme adopted for solving the technical problems is as follows: a printer chip fixing device, characterized in that: comprises a base, a gasket and a clamping cover; the middle part of the base is provided with a U-shaped groove, and two sides of the base are provided with V-shaped clamping grooves; the gasket is arranged in the U-shaped groove, and a plurality of arrayed small teeth are arranged on the surface of the gasket; the two sides of the clamping cover are provided with V-shaped buckles, and the middle part of the clamping cover is provided with a through hole; the V-shaped buckle is matched with the V-shaped clamping groove, and the V-shaped buckle can be buckled on the V-shaped clamping groove.

Preferably, the base, the clamping cover and the gasket are made of copper.

Compared with the prior art, the utility model has the beneficial effects that: the chip is placed in the U-shaped groove and on the gasket, a plurality of upturned small teeth are designed on the gasket, so that copper contacts on the back of the chip can be easily contacted, the small teeth are in close contact with 9 brass contacts, the clamping cover is clamped on the chip, through holes are formed in the clamping cover according to the structure of the front of the chip, useful things on the front of the chip are exposed from the front, and the V-shaped buckles on two sides of the clamping cover are clamped with the V-shaped clamping grooves on two sides of the base. Through the upward-tilting pinion array of the gasket, the clamping cover is pressed and clamped, and because all accessories are copper and are mutually communicated, the whole accessory is placed on the aluminum sample table and can be communicated to the back contact of the chip through all copper materials. Thus, the problem that the copper contact on the back of the chip cannot be contacted with aluminum foil paper is well solved, and the phenomenon of uneven chip is well solved. The utility model can be used for 15 chips at a time, and solves the problem that too many samples cannot be loaded in the prior art. The card cover is provided with a through hole which is made according to the structure of the front surface of the chip, and useful things on the front surface of the chip can be exposed from the through hole.
