| Zusammenfassung: | The utility model provides an elastic pin used for high density ceramic packaging. The pin structure is divided into a needle structure and a welding column structure. The middle part of the needle structure is provided with a spiral bending structure. The welding column is a hollow column, and the middle part of the welding column is provided with a spiral hollow structure. The needle structure is provided with above mentioned spiral bending structure on the middle part, and is also provided with cylindrical structures on two ends. The middle part of the welding column is provided with a spiral hollow structure, and two ends of the welding column are not provided with the hollow structure. After the board level installation welding, the welding flux is not contacted with the spiral bending structure part and the spiral hollow structure part. According to the utility model, the elastic pin structure can be formed, and the improvement of the installation reliability of the ceramic packaging board level can be facilitated. |
