Imitate the expense
In some layouts, inflexible flex will certainly not be a viable option, and also you need to do your due persistance in establishing the break-even factor where the prices have to do with equivalent. This sort of rate simulation can be done by considering the complete estimated costs for fabrication and also assembly. The PCBs can be priced quote prior to design, as long as the specifications of design are well comprehended (for example, the layer stack, approximated via count, track as well as room proportions, etc.). We did a rigif flex PCBmanufacturing price simulation with a real rigid flex PCB design as well as a relative rigid-cable-rigid matching. The component BoMs for comparison varied only in the cable television as well as connectors needed for the non-flex version. For our simulation, the standard design is included four-layer boards that use flexible cable as well as ports in between them, while the rigi flex circuits design is a four-layer PCB with 2 internal flexible circuits layers. PCB Manufacturing expense for both layouts is based upon actual PCB manufacturere quotes, as well as includes the cost of assembly.
Find your break-even factor
As the job quantity portrayed in Figure 1 hits 100 devices, the rigid flex PCB design becomes a more cost-efficient choice compared with the traditional design strategy. A vital factor for this price savings is that inflexible flex circuits do not utilize connectors/cables or call for any type of connector assembly. Likewise, they showcase raised dependability and also process yields. But that’s simply the tip of the iceberg.Because stiff flex PCBs require no cord assembly, their general assembly initiative is lowered, as is their examination intricacy– both of which drive down cost. In addition, fewer components have to be acquired, reducing the supply chain risk. Stiff flex PCBs can be made making product maintenance more convenient and therefore, more cost-efficient throughout the product lifecycle.
Design in 3D to guarantee success
Early sychronisation between the designers as well as the rigid flex PCB manufacturer, supported by the use of a modern PCB design software, is one more element making rigid flex PCB technology a more affordable option. Rigid flex PCB styles need closer partnership in between the developer as well as producer than typical inflexible board styles. The tradeoffs called for to generate a successful rigid flex PCB design translate to a collection of design policies the developer can develop with the fabricator’s input. These considerations consist of the number of layers in the design, products options, suggested sizes for traces and vias, adhesion methods, and also dimensional control. With the best design device, these factors to consider can be clearly specified and provided the correct weight they are entitled to beforehand to make sure that the rigid flex PCB can be appropriately maximized, additionally enhancing its general price as well.There’s no rejecting that existing market trends and also consumer demands are pushing designers and also design teams to their limits, compeling them to seek new alternatives to the electronic design obstacles they currently deal with. These obstacles, and also specifically the requirements being put on today’s mobile phones, are pushing rigid flex PCB technology into the mainstream, and also making it much more readily feasible for a range of applications. The availability of modern PCB design tools that sustain 3D product advancement, very early partnership, and all needed rigid flex PCB interpretations as well as simulation substantially decrease the discomfort of rigid flex PCB design as well as make it a much more compelling option– one that under the right circumstances is more affordable compared to rigid-cable-rigid PCB design. For today’s design groups, that option could simply indicate the difference between product success or failure.
