Black glue is a high viscosity black glue. Black glue has the characteristics of high temperature resistance, good heat dissipation, high hardness, easy dispensing, flame retardant, bending resistance, low shrinkage and low moisture absorption. These characteristics can meet the packaging requirements of high-speed dispensing. It is sealed with integrated circuits.

 

　　

　　The application scheme of black glue in high speed dispensing machine was briefly described with black glue as an example.

　　When high-speed dispensing machine is used for black glue dispensing in IC packaging, 16 solder joints of IC are required to be covered with glue. Glue can not be ejected from the cover and other places, and it can not be coated with black glue too high, so glue will not stick to the cover when the cover is covered. In addition, it needs to improve efficiency and save costs rather than waste. Glue. According to the above requirements, how should the high-speed dispensing machine finish the blackening work?

　　Integrated circuit black glue problem can be solved by high-speed dispensing machine, injection valve, controller and temperature controller. High-speed dispensing machine is a servo motion control system and software system, which has been verified in the market for ten years. It is equipped with charge coupled device image, cleaning and height measurement functions. The grinding screw can achieve 0.005 mm repetitive positioning accuracy. The injection valve has obvious advantages in preventing line pressing and controlling rubber thickness. The controller setting start time, valve closing time, rising time, descending time, needle bumping stroke, etc. Points, syringe pressure, heating temperature, etc. In order to control dispensing and dispensing position as well as the effect of moulding curing and blackening.
