About WPM Penzkofer
WPM Penzkofer Elektronic GmbH in Krailling near Munich is a contract manufacturer for PCB assembly and electronic module assembly. The company produces SMD and THT assemblies from prototypes to large-scale series, with two SMD production lines and seven placement machines at a placement capacity of 35,000 components per hour; technologies down to package size 0402 are processed. The service spectrum includes vapor phase soldering, selective soldering, cable assembly and assembly work. In addition, the company offers CAD design and PCB layout, worldwide material procurement of PCBs and electronic components as well as a corresponding component and PCB service. Quality inspection is carried out automatically via an AOI inspection system (Vi-3000) or visually; the quality management system is certified to DIN ISO 9001.
