Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of substrate clamps, in particular to a cleaning clamp for chip mounting substrates and a method for using the same. BACKGROUND

[0002] In the process of integrated circuit manufacturing, the cleaning process of chip mounting substrates is crucial, and the cleaning degree directly affects the reliability of chip mounting and the overall performance of electronic products. With the increasing integration and decreasing size of chips, the requirement for the cleanliness of the surface of the mounting substrate is becoming increasingly stringent. The performance of the cleaning clamp, which is the core tool for carrying and assisting the cleaning operation, plays a decisive role. Currently, most traditional cleaning clamps constrain the substrate through fixed clamping. When fixing the substrate, the contact area with the substrate is large, which is easy to leave indentations or stains on the surface of the substrate, affecting the cleaning effect and the quality of the substrate. Therefore, a cleaning clamp is needed to facilitate the stability of the chip mounting substrate during the cleaning process.

[0003] For example, the cleaning clamp for chip mounting substrates in application No. 202322055960.5 includes a box body, a support plate fixedly connected in the box body, a plurality of one-to-one clamping grooves fixedly connected on the support plate and the inner wall of the box body, a gas bag fixedly connected in each clamping groove, a clamping sliding block fixedly connected on the gas bag and slidingly connected in the clamping groove, and an extrusion plate slidingly connected in the box body. The extrusion plate, the bottom of the box body, and the inner wall of the box body form an extrusion cavity, and a hollow cavity is formed in the extrusion plate. By moving the extrusion plate towards the bottom of the box body, each substrate is synchronously moved downward under the action of its own weight until the through hole and the opening of one end of the U-shaped hole are connected in communication, and the air in the extrusion cavity enters each gas bag, causing the gas bag to expand and push each clamping sliding block. In this way, each clamping sliding block can limit and clamp each substrate, facilitating the subsequent full cleaning of each substrate.

[0004] However, in terms of current substrate clamps, the mainstream chip mounting substrate cleaning clamp generally adopts an edge constraint fixing mechanism. The clamping plate structure clamps and positions the edge of the substrate to ensure stability during cleaning. However, the shielding area formed after the clamping plate contacts the substrate significantly hinders the full infiltration and effective flow of the cleaning liquid, resulting in a cleaning blind area on the surface of the substrate. In common processes such as ultrasonic cleaning and spray cleaning, the shielding prevents the cleaning liquid from directly acting on the clamped part, making it difficult to completely remove contaminants such as flux and tin beads.

7. The cleaning fixture for a chip-attached substrate according to claim 6, wherein: The two groups of horizontal mounting frames (501) are arranged between the corresponding two groups of connecting vertical rods (404) respectively; the two groups of horizontal mounting frames (501) are provided with constraint insertion holes (502) at equal intervals respectively; the end positions of the four groups of constraint insertion holes (502) are provided with telescopic grooves (503) respectively; the four groups of telescopic grooves (503) are connected with rectangular through holes respectively.

8. The cleaning fixture for a chip-attached substrate according to Claim 7, wherein: The inner parts of the four groups of telescopic grooves (503) are slidably connected with butt joint clamping blocks (504) respectively; the four groups of butt joint clamping blocks (504) are provided with springs; the upper and lower sides of the four groups of butt joint clamping blocks (504) are fixedly connected with handles respectively; the two groups of clamping plate frames (505) are provided with cylindrical insertion rods for cooperating with the constraint insertion holes (502); the torsion grooves (507) are arranged below the corresponding plate clamping grooves (506).

9. A method of using a cleaning fixture for a chip mount substrate, the cleaning fixture for a chip mount substrate according to claim 8, wherein: The steps include: 1) vertically inserting the base plate into the plate clamping groove (506) of the clamping plate frame (505); at this time, the bottom supporting ball block (508) in the torsion groove (507) at the bottom of the lower clamping plate frame (505) can be flexibly rotated to adapt to the shape of the bottom of the base plate and provide stable support; then, the butt joint clamping block (504) is pushed to extend out of the telescopic groove (503) and be clamped into the butt joint insertion hole (405) of the connecting vertical rod (404); at the same time, the cylindrical insertion rod on the clamping plate frame (505) is inserted into the constraint insertion hole (502) of the horizontal mounting frame (501); through the cooperation of the butt joint clamping block (504) and the constraint insertion hole (502), the connection between the horizontal mounting frame (501), the clamping plate frame (505) and the connecting vertical rod (404) is ensured to be stable, and the omnibearing clamping and fixing of the base plate are completed. 2) After the preliminary cleaning treatment of the substrate, start the adjusting motor (103), the motor shaft drives the six-prism rod-shaped driving rod (104) to rotate, and then drives the driving gear (203) to rotate. Because the two groups of passive racks (205) are engaged with the driving gear (203) through the clamping teeth, when the driving gear (203) rotates, the two groups of passive racks (205) slide in the opposite direction along the inner adjusting groove (202), driving the synchronous sliding frame (206) to move. During the movement of the synchronous sliding frame (206), the sliding bottom block (208) is driven to slide through the outer beam rod (207), realizing the preliminary adjustment of the transverse position of the reverse adjusting sliding plate (301), so that the clamping plate part (5) is converted from a rectangle to a parallelogram state, and at the same time, the substrate is forced to tilt, so that the dead angle position generated during contact is leaked, facilitating the cleaning treatment in the later stage.
