About KWI electronic
KWI electronic is a Bremen-based company for custom electronics solutions in a small market segment. Its range of services extends from hardware and software development in cooperation with FLE electronic, through PCB layout with Target or Eagle and CAM data preparation (Gerber, P&P), to the manufacture of prototypes, zero and small series in SMT, THT and THR technology, including complete material procurement. The component spectrum covers passive components from 0402 as well as active components up to fine pitch 0.4 mm, QFN and BGA. For thermally demanding requirements, a vapor phase soldering system IBL Minilab is available, offering maximum process stability for multilayer and aluminum-core circuit boards (IMS). The offering is complemented by functional or in-circuit testing with test adapter concepts, project-specific final assembly with cable assembly, and CNC machining of front panels and enclosures. Customers come from industry, dental technology, rehabilitation technology, simulation and research, including Siemens, Thermo Fisher Scientific, Fraunhofer institutes and universities.

Circuit boards and components
Multilayer circuit boards
Standard base material of assembly manufacturing; can also be processed for thermally demanding applications via vapor phase soldering.
Aluminum-core circuit boards (IMS)
Heat-dissipating circuit boards, processed with the IBL vapor phase system for maximum process stability.
SMD components 0402 to fine pitch 0.4 mm, QFN, BGA
The entire component spectrum is processed on the Pantera XV-Plus placement machine with CSM7000-Plus inspection system.
