Circuits; printed

HS code 853400 covers the classification of printed circuits, which are essential components in a wide range of electronic devices and equipment. Printed circuits serve as the backbone for interconnecting electronic components, enabling the flow of electrical signals and power. This industry plays a crucial role in the broader electronics and technology sectors, supporting the development and manufacturing of a vast array of consumer, industrial, and specialized products.

The production of printed circuits typically involves a multi-step process. First, the circuit design is created using computer-aided design (CAD) software. The design is then transferred to a blank circuit board, often made of fiberglass or other insulating materials. The circuit traces and pads are then formed on the board, either through a subtractive process (e.g., etching) or an additive process (e.g., electroplating). Finally, the electronic components are mounted and soldered onto the circuit board, completing the assembly.

The main inputs required for the production of printed circuits include the base circuit board material (e.g., fiberglass, copper-clad laminates), conductive materials (e.g., copper, gold, silver), and various chemicals and solvents used in the etching, plating, and cleaning processes. Additionally, specialized equipment such as CAD software, circuit board fabrication machines, and soldering stations are essential for the manufacturing of printed circuits.

Printed circuits are a fundamental component in a wide range of electronic devices and equipment, including 851762 Machines and apparatus for the manufacture of semiconductor devices or of electronic integrated circuits and 847130 Automatic data processing machines and units thereof. The output of the printed circuit industry is consumed by various other HS codes, such as 851762 Machines and apparatus for the manufacture of semiconductor devices or of electronic integrated circuits, 851770 (Parts and accessories (other than covers, carrying cases and the like) suitable for use solely or principally with the machines of headings 8517 or 8525 to 8528), and 847130 Automatic data processing machines and units thereof.
