Chemicals for LED and Communication Electronics

Light-emitting diode (LED) is a solid-state semiconductor device that can directly convert electricity into light. The heart of an LED is a semiconductor chip with one end attached to an LED bracket as negative electrode, and the other end connected to the positive electrode of the power supply, the entire chip is encapsulated in epoxy resin.

LED bracket is a base for LED beads before encapsulation. Based on the LED bracket, the chip is fixed in, the positive and negative electrodes are soldered, and then encapsulated into an LED bracket with encapsulant and packaging glue, usually made of copper, also iron, aluminum, and ceramics, etc. LED brackets generally include through-hole LED brackets, piranha LED brackets, SMD LED brackets, and high-power LED brackets. Specialty chemicals for LED electronics refer to fine chemical materials supporting LED bracket plating.

Processing
Silver plating for LED brackets
The silver plating process for LED brackets is long, complex, with complicated control points and multiple affecting factors. Each process involves the use of chemicals, and the quality and stability of the chemicals directly affect the performance of the LED brackets. The following is the application of our specialty electronic chemicals for LED brackets at the customer end. The basic process of high-speed continuous silver plating for LED brackets is as follows: degreasing——activation——polishing——nickel plating——alkali copper plating——acid copper plating——nickel plating——alkali copper plating——silver plating——silver stripping——electrolytic cleaning——silver protection——air drying——drying.
