This is a successful case of sublimation in the laser industry

In recent years, with the breakthrough of domestic laser packaging technology, it has broken the embarrassing situation that the finished laser tube shell can only be imported from abroad.

In recent years, with the breakthrough of domestic laser packaging technology, it has broken the embarrassing situation that the finished laser tube shell can only be imported from abroad. Due to the high power and high instantaneous temperature of the laser, a large number of WCu materials are used as the heat dissipation base. However, the laser with tungsten copper heat sink size accuracy requirements are high, the surface quality requirements are very strict, resulting in many domestic do not pass. Through a series of measures such as special research and development, process adjustment and equipment improvement, our company has been able to mass produce tungsten copper heat sink materials for lasers. And with the domestic laser industry leading enterprises, such as Xi'an Juguang Technology, Shandong Huaguang Electronics and other established a stable cooperative relationship.

Ultra-mirror precision laser heat sink

Ultra-mirror precision laser heat sink material is the W90Cu10 material through precision grinding and polishing technology to obtain the roughness of the ultra-mirror surface within 20nm, and the surface can be nickel-plated and gold-plated, the surface roughness after plating can still reach within 20nm. This technique is divided into four steps:

(1) Preparation of high-density tungsten-copper materials

(2) precision cutting

(3) Super mirror grinding and polishing

(4) Super mirror nickel plated gold plated

Product features:

1. Excellent product size control accuracy, thickness tolerance ± 0.005mm;

2. Good solderability, roughness ≤ 20nm;

3, can provide semi-finished products and surface plated Ni/Au finished products;

4. Excellent flatness and perpendicularity;

5. The size can be customized according to customer requirements;

6, does not reduce the original physical properties of the material;
