Jet dispensing device and technology

Abstract

The embodiment of the invention discloses a jet dispensing device and technology. According to the jet dispensing device and technology, the jet dispensing environment pressure is controlled to reach the optimal working environment pressure through a low-pressure generating device and a low-pressure working box, and the optimal working environment pressure is obtained by testing in advance, so that the deformation and splashing caused by the collision between the high-speed and little jet dispensing adhesive drop and a wall surface of a workpiece mounting base plate and the collision between the drops can be effectively inhibited, and as a result, the jet dispensing quality and consistency can be effectively improved, and the technical problems of high instrument precision, large difficulty in jet volume control of adhesive, high manufacturing technology requirement, complex technological operation, and low jetting efficiency in the prior art can be solved.

Description

technical field [0001] The invention relates to the field of jet dispensing, in particular to a jet dispensing device and process. Background technique [0002] Jet dispensing technology has the characteristics of non-contact, high speed and high efficiency, and is the next generation of emerging fluid dispensing technology in the field of microelectronic packaging technology. Whether abroad or at home, a lot of theoretical research and practical tests have been invested in jet dispensing technology, and a large number of theoretical achievements and technical experience have been accumulated. Many product equipment based on jet dispensing technology have also been put into the manufacturing industry. The collision between the glue droplet and the substrate, and between the droplet and the droplet causes the droplet to deform and splash. The degree of deformation and splash directly affects the bonding quality and forming accuracy of the dispensing, as well as the sputtering...

Problems solved by technology

[0005] The embodiment of the present invention discloses a jet dispensing device and process. The environmental pressure of jet dispensing is controlled to the optimum working environment pressure value obtained in advance experiments through a low-pressure generating device and a low-pressure working box, effectively suppressing high-speed, micro-volume The degree of deformation and splashing caused by the collision between the jet glue droplet and the wall surface of the workpiece mounting substrate, and between the droplet and the droplet effectively improves the quality and consistency of the jet dispensing, and solves the problems in the prior art. The precision of the required instruments is high, it is difficult to control the injection volume of the glue, the manufacturing process requires high requirements, and the technical operation is complicated, which leads to the technical problem that the injection efficiency is greatly reduced
