We can also recognise collisions between board and housing parts in the early development stages in order to estimate if the flex connectors of the actual product are going to be reliable or not.”  Flex-rigid construction can be adopted for a number of reasons. A product can have parts or sections that are required to move repeatedly, while maintaining electrical Audio Transformers Impedance Levels 10 ohms to 250k ohms, Power Levels to 3 Watts, Frequency Response ±3db 20Hz to 250Hz.

Alternatively, there may be no movement involved after final assembly, but separate circuit blocks may be positioned with different orientations in a complex housing, where there is insufficient flat surface area to locate a single, conventional PCB. A variant of this is where the final arrangement of PCBs is so space-constrained that the best way of completing its assembly is to fold it up. Flex-rigid PCBs offer an elegant solution that can be more reliable than connectors and wiring looms, take up less space and deliver more predictable interconnect performance.  Designing such interconnects as part of a single board demands extensive knowledge of how the “flex” part of the PCB behaves; what bend radius it can accept, how it terminates, how much space must be allowed for strain relief, and for the changing geometry of the flex itself, as it moves. Conventionally, this has been handled by a mechanical engineer, skilled in the use of a general-purpose 3D CAD package – or, perhaps more often, by an experienced engineer drawing on his or her knowledge of how such interconnects behave. With Altium Designer, all of the behaviour of flex-rigid constructions is handled within a single design environment, all the way from defining the copper pattern and the layer structure (with total integration to the netlist information in the electrical design context) through to reserving 3D space in the product’s enclosure for any repetitive flexing.  Kaba was also able to exploit a further feature for 21st-century prototyping: 3D printing. Altium Designer can output print files that will quickly generate (non-functional!) space models on a 3D printer. Even when the design files and on-screen displays have verified that all necessary clearances are met, having a physical model available at very low cost that precisely mimics the final PCB assembly/enclosure – and that can be handled and evaluated for ergonomics – adds a further dimension to the design process.  With growing confidence in the combined electrical/mechanical virtual representation, can come further benefits to the design process and in particular, to the allimportant design cycle time and time-to-market. Traditionally, there have been several points in the evolution of a product when a physical model has had to be produced (working or otherwise): At the product concept stage to convince management or a client to proceed; or at major design revisions and reviews. The time taken to produce a work-in-progress prototype – or even a space model – is time that could be spent progressing the design. With the certainty that what the software shows in a 3D view will be accurately reproduced in physical and functional terms, that time can be saved or greatly reduced. www.electronics-eetimes.com Electronic Engineering Times Europe March 2015 41
