Description

Technical Field

[0001] The invention belongs to the technical field of electronic packaging, and in particular relates to a hermetic sealing welding device and method for a multi-faceted SIP module. Background Art

[0002] With the development of electronic industry technology, the system-level package (SIP) is small and exquisite, and powerful, and is widely used in communication satellites, military radars, information highways, program-controlled telephones, mobile phones, GPS, weather forecasts, remote sensing, telemetry, cable TV, medical care, energy, transportation, environmental engineering, automated production, and daily life. Microelectronics technology is infiltrated in all fields.

[0003] In modern wireless communications, military radar and other systems, phased array antennas have developed from relatively planar array antennas to conformal array antenna technology. Among them, flexible conformal array antennas are a more advanced type of conformal array antenna technology. They can not only conform to any curved surface, but also dynamically adjust and adapt as the shape changes. They also have better adaptability to vibrations and shape changes caused by aerodynamics, heat and cold in aircraft. For this reason, in special cases, the SIP module design in phased array antennas has also developed from traditional rectangular and circular structures to multi-faceted contour structures. However, when using current existing technologies to package multi-faceted SIP modules, the accuracy is poor and the efficiency is low, making it difficult to meet production requirements. Summary of the invention

[0004] The purpose of the present invention is to overcome the defects of the prior art and provide an airtight sealing welding device and method for a multi-faceted profile SIP module, so that the multi-faceted profile cover plate and the multi-faceted profile solder can be quickly and accurately aligned during the production process, and the pre-spot welding fixation can be quickly completed. The conical spherical structure of the pre-fixed solder electrode pen ensures that a stable spot welding current is formed during the pre-spot welding process, ensuring that the multi-faceted profile solder and the multi-faceted profile cover plate are firmly integrated, while reducing the problem of through-melting overflow during the spot welding fixation process, thereby greatly improving the packaging accuracy and packaging efficiency of the multi-faceted profile SIP module.

A plurality of evenly spaced placement grooves 12 are provided in the same row of pre-spot welding paths. Two adjacent placement grooves 12 are connected by an electrode avoidance groove 8. The placement grooves 12 and the electrode avoidance groove 8 are both formed by depressions on the surface of the pre-fixed solder base 1.
