Double Sided Flexible Printed Circuit Boards

When Accuracy is Priority ?

Double sided flexible printed circuit boards are similar to single sided ones except they contain several more connections and components. In double-sided PCBs, the connections and components extend beyond one side. They are placed on both sides, thus increasing the complexity of the product. Double sided PCBs comprise two conducting layers that contain the components and the copper traces. Between these two layers, an insulating material is placed.

Since double-sided PCBs are not as complex as multi-layered PCBs, the time taken for production is not that high either. Hence, the overall costing is comparatively lower. Double-sided PCBs can be designed with high density connections. They can incorporate more components and connections allowing them to be used in complex applications at a lower price as compared to their multi-layered counterparts.

Why Opt for Double Sided Flexible Printed Circuit Boards ?

More design variation compared to single-sided PCBs
Circuit traces can be accessed from either side of the board
Completely flexible allowing for easy integration
Without the use of interconnections, the assembly costs are lower
Turnaround time is lower compared to multi-layer PCBs
With lower time, PCBs are less expensive

Military Grade Flexible PCBs from A-Flex

A-Flex provides various ruggedly designed options for military grade flexible PCBs. Sometimes, the connectivity between the two sides of the PCB might not be as reliable as needed. It is important to create reliable connections, not just between components and the application but also between the two sides of the PCB. This can be accomplished by drilling a small hole through the PCB. This hole is then plated with electrically conductive material. This hole serves as the connection between the two sides, thus improving reliability of the product. This method was developed after trying out many different methods. The Plated Through Hole (PTH) technology, borrowed from rigid PCBs is a simple yet effective method of improving reliability.

A-Flex strives to provide outstanding results at every step of design creation and fabrication. Collaborating with us provides our clients with reliable high speed PCBs at a fraction of the cost charged by most competitors.
