You may have guessed it already, flex-rigid printed circuit boards got their name because of its combination of rigid and flexible circuitry areas. This type of printed circuit board has more multiple layers when compared to conventional designs just like the flexible printed circuit board.
Depending on each product needs, these additional conductive layers are usually outlined with either flexible insulation or rigid insulation. On the outer layers on a printed circuit board often contains covers for safety or exposed pads no matter how many layers there are. For the primary rigid layer, conductors are deployed. However, flexible plated perforated holes are utilized in the case of additional layers for both rigid and flexible.
Despite the fact that some projects call for using this rigid design and technology just like circuit boards for military, it has its own limitations that normally prevents manufacturers from utilizing these less flexible and larger printed circuit boards. It should be noted that in some products such a mobile device or some other portable devices, the standard printed circuit boards won’t give be the best choice to use, in fact, these devices would suffer. This is because there are too many moving components and moving parts that its performance won’t be effective when it is being subjected to some conditions. For example, there is a need for mobile devices to be lightweight, portable, and be able to withstand certain conditions like cold, heat and sometimes moisture.
Since we have known about the traditional standard flex-rigid printed circuit board, let us take a look at its pros and cons;
Pros of the Flex-Rigid Printed Circuit Board
- It is very reliable
- It is excellent because of the reduced dependency for more solder joints
- It is cheaper when compared to flexible printed circuit boards
- It has an excellent temperature resistance
- It doesn’t often require maintenance
Cons of the Flex-Rigid Printed Circuit Board
- It is not suitable for more portable devices
Devices produced with this printed circuit board tends to have more weight than the flexible printed circuit board.
Making the choice of which printed circuit board to use in the production of your devices shouldn’t be such an issue for you, you should look for companies offering this service to help you out in your decision making.
