Custom Tuned and Terminated Micro-coaxial Assemblies for Ultrasound Applications

Scottsdale, AZ – High Speed Interconnects (“HSI”), a full service extruder and manufacturer of high performance coaxial cable and assemblies, has recently announced custom, fine-wire and fine-pitch diagnostic imaging assemblies for medical device OEMs producing next-generation ultrasound equipment.

HSI’s proprietary extrusion capabilities produce fine-wire coaxial cables ranging from 40-50 AWG and these can be packaged as either ribbonized or bundled assemblies. Fine-pitch, microscopic termination capabilities range from 1 mm to 0.175 mm.  Despite their small size they are extremely durable (exceeding in excess of 500,000 flex’s at ninety degrees) and capable of withstanding the demands of Ethylene Oxide gas (EtO/EO) sterilization.

These micro-coaxial, medical assemblies are offered as insulated single coax’s, twisted shielded pairs, parallel pairs, or differential pairs, and can be delivered terminated to flex circuits, PC boards, transducers, optics, emitters and detectors, and other medical sensors.

Since HSI extrudes its own coaxial cable and formulates its own VP90TM ePTFE dielectric, each cable can be customized to be ergonomic, light and miniature. Their capacitance specifications can also be tuned to exceed less than 12 picofarad (pF) per foot, and impedance can be tuned up or down by 0.05 an Ohm.

From conceptual New Product Introduction (NPI) design, through first article qualification and production, HSI adopts Design For Manufacturing & Assembly (DFMA) practices, which yield excellent lead times and unparalleled cost savings. HSI adheres to FDA compliant GMP practices. Certifications include AS9100 revision C, ISO9001, EN13485 (currently pending and compliant), IPC 610/620, and ITAR Registration. HSI is also factory-certified in North America to properly terminate to Hirose, IPEX, and JAE micro-coaxial connectors.
