DFM solution brings shorter delivery times and increased quality
6 April 2006Manufacturing / Production Technology, Hardware & Services
Valor Computerized Systems has completed a successful implementation of its DFM (design for manufacturability) solution at Siemens Bocholt in Germany for effective costs management and a faster route to product. Based on the implementation of a successful Six-Sigma methodology, Siemens has established a stable process with increased reliability across its bare board and assembly manufacturing operations.
According to Mr Elshorst, project manager electronic design at Siemens (Bocholt), there were many reasons for selecting the Valor DFM solution. "Valor provided us with extensive DFM analysis and checking capabilities that were not possible within the constraints of the PCB CAD systems. We also wanted to improve data management and bi-directional communication with our bare board manufacturer. By reducing set-up time and with better handling of manufacturing change orders we have achieved shorter delivery times, and reduced our manufacturing costs."
The dynamics of manufacturing DECT products for the fast-paced consumer market means high volume, short lifecycle and high ramp-ups, with seasonal peaks. Siemens Bocholt has responded to this with a stable, continuous process delivering consistent quality based on the established SixSigma methodology and best-in-class DFM and assembly tools.
Six-Sigma can be defined as a disciplined, data-driven approach and methodology for eliminating defects (driving towards six standard deviations between the mean and the nearest specification limit) in any process - from manufacturing to transactional and from product to service.
Continues Elshorst: "The feedback, verification and control of the manufacturing information from the Valor DFM suite has certainly reduced errors and risks associated with high volumes of boards in our goal of first-time, right first time manufacturing. The impressive performance of the ODB++ format has also given us standardisation with our suppliers and partners, through an optimised process."
The Valor DFM software, based on Enterprise 3000, is a unique, virtual manufacturing system that enables OEMs to simulate the entire production process, from design through manufacture to assembly, concurrently with the design process. The company says that designs are optimised using a physical design model of the PCB assembly where revision spins are virtually eliminated, resulting in faster times to market and improved product quality.
