Specialty chemicals and equipment for new energy refer to surface engineering specialty chemicals and dedicated production equipment required by the lithium batteries, photovoltaics, and other new energy industries, such as One-Step All-Wet Process of Composite Copper Foil Preparation Technology, Two-Step Process Composite Copper Foil Water Electroplating Equipment Technology, high-efficiency plating additive for monocrystalline heterojunction solar cells, etc.

The term 'passive components' originates from the Taiwanese electronics industry; in mainland China, they are often referred to as 'passive devices.' Passive devices are a crucial category in microwave and radio frequency devices and hold a very important position in microwave technology. Passive devices mainly include resistors, capacitors, inductors, converters, attenuators, matching networks, resonators, filters, mixers, and switches. Because the materials used in these products are often acid-sensitive, a near-neutral chemical treatment agent is required during the electroplating process, i.e., specialized electronic chemicals for passive components.

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.

Components such as antenna vibrators, radio frequency devices, filters, battery wires, cavities, screens, and microphone/earphone receivers used in communication base station equipment, mobile phones, and other communication electronic products all require surface treatment. Surface treatment can give the component surfaces properties such as temperature resistance, heat resistance, corrosion resistance, oxidation resistance, interference resistance, low resistivity, special colors, and conductivity. Therefore, electronic chemicals are extremely widely used in the mobile phone and communication electronics industries.

PCB (Printed Circuit Board) is one of the important components of the electronics industry. It plays a role in supporting components and chips within the complete machine, providing interlayer interconnection and conduction, preventing solder bridges and aiding in maintenance identification. PCB specialty chemicals refer to fine chemical materials specifically designed for the PCB manufacturing industry.
