Anti-static products are essential for various industry applications
In the production workshop of semiconductor devices, the output of integrated circuits (especially VLSI) will be greatly reduced due to the adsorption of dust on the chips. Operators in integrated circuit production workshops wear clean overalls. If the human body is stationary, it is easy to absorb dust. If the dust enters the operation site, it will affect the product quality, reduce the product performance, and greatly reduce the Ic output. If the radius of the adsorbed dust particles is greater than 100. The line width is about 100 μm. And the film thickness was 50 μm. Product may be discarded.
Therefore, it is necessary to establish an electrostatic protection system in integrated circuit processing and packaging. Integrated circuit packaging production lines have stricter requirements for static electricity. In order to ensure the normal operation of the production line, anti-static building materials have been fully decorated in its clean workshop, and all personnel entering and leaving the clean workshop are equipped with anti-static clothing. Hardware measures have been taken In order to cooperate with the normal operation of the integrated circuit packaging production line, we have formulated enterprise standards or specific requirements for anti-static. As we all know, LED is a semiconductor product.
In the actual production process, the direct contact and indirect contact between the human body and related components are mainly used to generate static electricity and damage the components. The light-emitting diode of the LED display is a diode composed of a PN junction. Breakdown between the emitter and base will cause a sharp drop in current gain. This function may not occur immediately after the LED itself or the integrated circuit in the driver circuit is affected by static electricity. Damaged, but these potentially damaged components often appear during use, which can have a fatal impact on the lifespan of the monitor.
Then it is necessary to prevent the generation of static electricity. It is recommended that assemblers wear anti-static clothing (such as anti-static clothing, hats, shoes, finger cots or gloves, etc.). ) and an anti-static wrist strap. surface or internal static dissipation). The assembly table (workbench) needs an anti-static mat and is grounded. LEDs require an anti-static case. Soldering irons, foot cutters, solder pots (or automatic reflow equipment) also need to be grounded. Use anti-static sponge or packaging for LED packaging bags and semi-finished packaging materials
