Description

Technical Field

[0001] This invention relates to the field of electronic automation technology, and more specifically to a CCGA weld post appearance auxiliary selection device. Background Technology

[0002] Currently, the interconnect pillars in CCGA (Ceramic Pillar Grid Array) packages are made of special ceramic materials, with carefully selected materials and processes designed to meet the stringent requirements of aerospace applications. These ceramic pillars are typically composed of high-temperature co-fired ceramics (HTCC) or low-temperature co-fired ceramics (LTCC). The manufacturing process of ceramic pillars is highly precise, first through ceramic slurry printing and then high-temperature sintering and curing. To ensure good conductivity, the interior of the pillars is usually filled with conductive metals such as tungsten or molybdenum, and the surface is plated with gold or nickel. This structural design not only ensures the reliability of electrical connections but also greatly improves soldering strength. The gold plating also effectively resists corrosion from atomic oxygen in the space environment. These characteristics make CCGA an ideal choice for electronic systems in spacecraft such as satellites and deep space probes, providing a solid guarantee for the long-term reliable operation of aerospace electronic equipment in extreme environments. During the manufacturing process of CCGA solder pillars, due to various uncontrollable factors, scratches and soldering defects are unavoidable on the surface. Therefore, visual inspection is a crucial step. Manual hand-picking is not only inefficient but may also cause secondary scratches, failing to meet production requirements. Summary of the Invention

The inner diameter of the thin tube 12 is 1.4 times the diameter of the weld column 4. Therefore, the weld columns 4 will be arranged vertically in the thin tube 12 one by one. The bottom weld column 4 will fall into the feed hole 18 of the discharge block 14.

After the feeding is completed, the cylinder 13 drives the discharge block 14 to retract, and the next weld column 4 will continue to fall into the feed hole 18.

[0025] The welding column 4, falling into the upper slide 19, will enter the lower slide 29 of the lower track block 23 under the action of gravity and the limiting effect of the upper slide 19. Then, it will fall to the lowest point of the slide 29 and fall between the blocking block 24 and the rotating shaft 22. Then, the rubber sleeve on the surface of the rotating shaft 22 will drive the welding column 4 to rotate. During the rotation, the electron microscope 21 magnifies the image, and the staff will identify and identify it to determine the quality of the welding column 4. When the welding column 4 is qualified, the second cylinder 25 controls the blocking block 24 to retract, and the welding column 4 will fall directly into the qualified product collection box 34 along the receiving block 31 under the action of gravity. When the welding column 4 is unqualified, the second cylinder 25 controls the blocking block 24 to push out, and the welding column 4 will fall into the sorting block 32 along the receiving block 31 and fall into the unqualified product collection box 35 along the inclined channel of the sorting block 32, thereby realizing the selection of the appearance of the welding column 4.
