Bare Printed Circuit Board Manufacturing

This includes establishments primarily engaged in manufacturing bare (i.e., rigid or flexible) printed circuit boards without mounted electronic components. These establishments print, perforate, plate, screen, etch, or photoprint interconnecting pathways for electric current on laminates.

Semiconductor and Related Device Manufacturing

This includes establishments primarily engaged in manufacturing semiconductors and related solid-state devices. Examples of products made by these establishments are integrated circuits, memory chips, microprocessors, diodes, transistors, solar cells, and other optoelectronic devices.

Capacitor, Resistor, Coil, Transformer, and Other Inductor Manufacturing

This includes establishments primarily engaged in one or more of the following: (1) manufacturing electronic fixed and variable capacitors and condensers; (2) manufacturing electronic resistors, such as fixed and variable resistors, resistor networks, thermistors, and varistors; and (3) manufacturing electronic inductors, such as coils and transformers.

Electronic Connector Manufacturing

This includes establishments primarily engaged in manufacturing electronic connectors, such as coaxial, cylindrical, rack and panel, pin and sleeve, printed circuit, and fiber optic.

Printed Circuit Assembly (Electronic Assembly) Manufacturing

This includes establishments primarily engaged in loading components onto printed circuit boards or who manufacture and ship loaded printed circuit boards. Also known as printed circuit assemblies, electronics assemblies, or modules, these products are printed circuit boards that have some or all of the semiconductor and electronic components inserted or mounted and are inputs to a wide variety of electronic systems and devices.

Other Electronic Component Manufacturing

This includes establishments primarily engaged in manufacturing electronic components (except bare printed circuit boards; semiconductors and related devices; electronic capacitors; electronic resistors; coils, transformers, and other inductors; connectors; and loaded printed circuit boards).
