Abstract
Description
Technical Field
[0001] The utility model relates to the field of optical communications, in particular to a pin welding auxiliary jig. Background Art
[0002] In the existing optical communication industry, there are photodiodes of various sizes that need to be soldered to lead out the electrodes to facilitate later testing or welding assembly. Figure 1-Figure 2 As shown, currently, positioning is performed using a high-temperature resistant sleeve to ensure concentricity between the pins and the photodiode base. This operation presents four problems: 1. High-temperature resistant materials are consumed significantly, making them non-recyclable and costly; 2. The sleeve is time-consuming and expensive; 3. The sleeve can deform and bend, resulting in poor concentricity and poor welding quality; 4. Although the material is high-temperature resistant, volatiles are still generated during high-temperature welding. Furthermore, the insulating material adheres to the pins and photodiode electrodes, resulting in poor contact between the electrodes, a dirty appearance, and difficulty in cleaning.
