About Ka-Ro electronics
Ka-Ro electronics GmbH was founded in Aachen in 1988 and has been specializing in electronics manufacturing (Electronic Manufacturing Services) for over 35 years. The company assembles custom electronic assemblies using SMT and THT technology on three production lines – from prototypes and small series to large series with a capacity of 16 million components per month. Since 2001, Ka-Ro has also developed and manufactured its own Computer-on-Modules (Solder-in-QS and Plug-in-TX families) with processors from NXP, ST and Renesas; the annual capacity is over 500,000 modules. The service portfolio includes hardware and software development, material procurement, programming service, final inspection and support from a single source. At the Pascalstraße 22 site in Aachen, development, SMT/THT manufacturing and quality management are all under one roof; a certified quality management system according to ISO 9001:2015 ensures process stability. Through an international sales network, Ka-Ro supplies more than 1,000 customers worldwide.
