Technical Field
[0001] The utility model relates to a tool used for high-precision metallization of multiple surfaces of a heat sink. Background Art
[0002] In the manufacturing process of electronic products and equipment, heat sinks (radiators) are important thermal management components and are widely used in electronic components to improve their heat dissipation performance and extend their service life. With the advancement of technology and the improvement of electronic product performance, the requirements for heat sink metallization are becoming increasingly stringent. In particular, the application of multi-surface metallization technology can effectively improve the heat sink's thermal conductivity and overall performance.
[0003] Currently, the traditional heat sink metallization process has the following problems: multi-sided metallization requires metallization on multiple surfaces of the heat sink, which is a cumbersome process and leads to low production efficiency; during the traditional fixing and photolithography process, the ceramic roots are easily affected by external forces and may be displaced or damaged, resulting in unqualified finished products; existing tooling often cannot ensure the stability and neat arrangement of parts, and operators need to spend a lot of time on adjustments and corrections, which increases labor intensity.
[0004] Due to the above reasons, high scrap rates often occur during the production process, which directly affects production costs and corporate profits. Therefore, technical personnel in this field urgently need an optimized tooling structure to reduce the difficulty of operation, increase accuracy, and reduce the damage rate of the root strips for high-precision metallization of multi-sided heat sinks.

[0008] Furthermore, at least one protrusion is provided at the corners of the frame, and a first groove and a second groove are also provided at the corners of the frame. A third groove and a fourth groove are provided on the protrusion, and first and third clips are provided on both sides of the first push block to match the first and third grooves respectively, and second and fourth clips are provided on both sides of the second push block to match the second groove and the fourth groove respectively.
