PCB design and layout services providers generate schematics and CAD files for printed circuit boards

Printed circuit board (PCB) fabrication services design and fabricate circuit boards. They differ from electronic manufacturing services, which populate and assemble boards. 

Computer-aided design (CAD) services assist in the computerized design, three-dimensional (3D) modeling, and printing and drafting of engineering components and assemblies

Engineering design firms provide total design for new components, products and equipment, including load analysis, part and material specification, manufacturing drawings, product manuals, and often manufacturing support and/or certification documentation

Motor speed controllers are electronic devices that control motor speed. They carry specifications for drive type, product classification, electrical ratings, and operating parameters

Motor controllers receive supply voltages and provide signals to motor drives that are interfaced to motors. They include a power supply, amplifier, user interface, and position control circuitry.

Crushers and mills are used to reduce chemicals, materials or other products to a desired particle or aggregate size range.

Gearmotors consist of an AC or DC motor with an integral gearbox or gear head that steps delivered speed up or down

Rapid prototyping equipment produces a three-dimensional (3D) paper, plastic, wax, ceramic or metal prototype or pattern.

Resistors are electrical components that oppose the flow of either direct or alternating current. They are used to protect, operate, or control circuits.

CNC machining services use fast, repeatable, and programmable machines which can function while unattended in order to manufacture parts quickly and efficiently.

Signal transformers transfer information from one circuit to another by electromagnetic induction. They are used to increase or decrease the voltage from one side of a power transformer to the other.

AC motor drives interface controllers to AC motors. They match the control signals (voltage and power levels) as well as the signal type (analog or digital). They also provide power conversion, amplification, and the sequencing of waveform signals.

Cutting services use a variety of cutting methods to fashion materials into predefined shapes or sizes.

DC motor drives act as the interface and power supply between a motion controller and a DC motor.
