Circuit Design Specialties Inc. (CDS) is an electronics contract manufacturing company headquartered in Plano, Texas, providing PCB design, printed circuit board manufacturing, electronic assembly, cable assembly, and new product development services. The company works with customers in industrial, medical, and military markets and provides manufacturing support from initial product concepts and prototyping through production and finished electronic assemblies. Circuit Design Specialties has been providing PCB layout, manufacturing, and assembly services since around 1990, while business directory information lists the company as founded in 1989.

The company provides professional PCB layout services for complex electronic designs, including high-layer-count boards, blind and buried vias, flex and rigid-flex boards, mixed-material boards, high-speed designs, and impedance-controlled circuitry. Its PCB manufacturing services use customer CAD data, Gerber files, and IPC-D-356 net lists to manufacture and test boards according to project requirements. Circuit Design Specialties also provides PCB assembly with component sourcing and inspection throughout the manufacturing process.

Beyond PCB manufacturing, CDS offers custom cable assemblies and wiring harnesses for industrial, medical, and military applications. Its electronic product design service supports new product introduction from concept and design through prototyping and manufacturing. The company also provides final box-build assembly, allowing customers to receive more complete electronic products rather than individual circuit boards.

Circuit Design Specialties maintains quality and compliance programs that include ISO 9001:2015, ISO 13485, ITAR registration, IPC standards, X-ray inspection, flying-probe testing, ESD controls, and finished-product quality control. Its Texas facility supports U.S.-based electronics manufacturing for companies requiring PCB design, assembly, prototyping, cable manufacturing, and production services.
