Anti-static solution for the chip:
First, the importance of chip anti-static
As the speed of the chip is mentioned, in order to shorten the pin length and reduce signal crosstalk, more and more flip-chips are used for packaging of very large-scale IC chips such as CPU and SOC. The flip chip usually has a large area, and the chip itself becomes A huge capacitor. If the chip designer does not have enough knowledge of the problem, the current release channel is not set in the chip, so that the net charge is continuously accumulated, so that the chip will generate a strong electrostatic discharge when it contacts the workbench or the package. As a result, the chip damage is reduced during the manufacturing process, and the production cost is increased.
Second, the chip anti-static method: the chip should be placed in the anti-static component box, can not be stacked at random, take it with anti-static tweezers, not directly by hand. Not only is the chip storage important, but the transportation also needs to pass the anti-static transportation vehicle. The human body protection needs to wear anti-static clothing, anti-static gloves, anti-static shoes and so on. If the chip is hand soldered, ground the antistatic wrist strap with an antistatic workbench. Anti-static is a system, from management to protective facilities, personnel training to monitoring and testing, etc., requires professional ESD engineers to control all aspects.
Therefore, we recommend that our professional teachers assist you in guiding the ESD system and make an ESD anti-static control program based on the sensitivity requirements of components such as chips.
