Laser welding packaging device

  At present, when special parts such as semiconductor devices, integrated circuits, optoelectronic devices and other special parts are subjected to laser welding and packaging operations, the welding materials are exposed to the air and are particularly susceptible to oxidation under high temperature conditions, resulting in pores, slag inclusions, cracks, low welding strength, etc. Welding defects have led to a soaring failure rate of devices such as poor airtightness, low strength, and impact resistance. In particular, impact resistance defects will cause damage to high Mach flying devices, causing major safety accidents and property losses. At present, the domestic market urgently needs A laser welding and packaging device that can be under vacuum conditions or under special atmosphere protection, has a good man-machine environment and flexible equipment, and meets the needs of high-end devices, especially special devices for aerospace high-speed aircraft.

  Aiming at the shortcomings of the original technology, Mikrouna provides a laser welding glove box based on atmosphere protection. In order to solve the influence of humidity in the air and impurities in the air during laser welding, the glove box has two 90 In the square cabin, the left side is the heating cabin, and the right side is the transition cabin. The maximum temperature of the heating cabin is 200℃. The heating plate can be rapidly cooled at the same time. The outer side of the square cabin door is a manual door, the inner door is an automatic door, the inner and outer doors are interlocked, and gloves The cabinet is cleaned by a flow meter, and it can also be connected to a purification system. Its characteristics are: 1. Low leakage, low water and oxygen content in the box, stable overall performance of the equipment, and real and reliable water and oxygen detection.
