Re-Engineering of Electronic Assemblies
a new BFK-service for electronic industry and EMS companies
Change of owner at BFK-Services
An internally necessary change - but without impact on our business partners.
BFK-NCS-India
BFK cooperation with NCS, Bangalore, India concerning CAM/SCAN/DIGI-services
Impedance Construction
The production of impedance controlled multilayer boards requires close cooperation with a specialized PCB producer. We, BFK-Services, can fall back:
- on own experience for decades
- on the experience of our PCB-partners, especially of ELTOS S.p.A., Arezzo (I)
- on the impedance calculation software from POLAR
Volume of our service in this field:
- advise our customers regarding impedance in stage of conception
- importing/checking customer data with creation of adjusted stack-ups
- if applicable with alternative proposals (optimized for cost or tolerances)
We calculate a lot of different impedance models, expected tolerances of impedance and expected layer gaps and total thickness of the whole construction regarding material properties, copper balance of the layers, prepreg properties and we calculate the needed correcture of line width resulting from those calculations.
We provide this service to PCB producers and to OEMs as well.
HDI/SBU Multilayer Conceptions
HDI (High Density Interconnection) and SBU (Sequential Built Up) have been established as common expressions for the production technology of highly integrated PCBs. Belonging to it are further expressions like blind vias, burried vias and technologies like laser drilling, hole plugging etc. Most of electronic developers have been told about it.
However - which technologies are the most reliable and cost-effective ones for a special interconnection problem? At the interface between PCB production technologies and electronic development we can find constructions which can provide reliable production, minimal cost and a wide range of qualified producers.
Of course, we can fall back here, too, on the experience and innovation of our proven partners, especially ELTOS S.p.A.
Rigid-Flex PCBs
For al long time rigid flex boards have been regarded as "unaffordable" for civil applications. In aerospace and military industries they have been employed since decades because their reliablity but in millions of high-tech products like digicams, too - especially from Japan. But the factories there are typically "inhouse" producers and not available for the free market.
So today only few PCB shops are able to provide rigid flex technology like our partner, CSI Sud-Ouest in Toulouse, France. Together witch CSI and other - not European - producers BFK offers support for rigid flex technology, too, especially we provide:
- qualified complete rigid flex conceptions and stack-ups
- qualified material selection
- design rules, qualified for rigid flex PCB production
