    <br>Flexible polymer circuit board (PCB) manufacturing technology has become increasingly popular due to its many benefits. A well-made flex PCB is lightweight, sturdy, convenient for use in demanding applications, and able to withstand the harshest conditions. In fact, the many physical benefits of flex PCB are that it provides greater resistance to impact and vibration, which is particularly beneficial for wearable electronics and satellites. The ability to add or subtract components also increases the available configurations and performance capabilities.<br>
    <br>There are a variety of flex pcb fabrication options available to meet the diverse needs of manufacturing engineers. One of the most common forms used today is the closed cell foam, which is made up of one or more layers of flexible materials including plastics, metals, or wood. The materials are held together with the use of plastic clips and metal fasteners, which allow the individual components to move between and within the open cells. This flexible component method of manufacturing significantly reduces the overall thickness of the circuit board, which allows for greater usability in complex designs. However, because this flexible PCB construction does not provide an opportunity to incorporate fine details such as traces and resistors, it typically requires greater investment in tools and techniques to create the desired circuit boards.<br>
    <br>Another flexible option is the construction of flexible but rigid components. Rigid PCBs can consist of several layers of polyurethane foam and various other materials. The foam may have a plastic backing to help it adhere to the circuit board, while providing superior electrical conductivity and flexibility. While these rigid PCBs provide superior conductivity and flexibility, they lack the ability to be flexed and bent, which limits their use in many unique situations.<br>
    <br>The benefit of using flex pcb designs is that they allow for the production of circuit boards with greater functionality. Typically, flexible pcb circuit boards are used in the packaging and marketing of electronics as well as in computer industry applications. Because flex pcb designs can be flexed into numerous shapes, they can also be bent into many unique forms. For instance, a standard rigid PCB can often be formed into hollow tubes, which have the potential to become expandable if filled with a liquid medium. Additionally, a number of different sub sandwich structures, called bendies, are available which can form into numerous shapes, including hexagonal tubes.<br>
    <br>Some of the most innovative uses for flex pcb designs are those which take advantage of the benefits of view. A vial is a small ring, usually diameter smaller than the product it houses, that contains a small hole. These visas can be applied both inside and outside of the PCB, allowing the PCB to be positioned in a number of unique ways. For instance, as can sometimes be used as door contacts, which enable components to be placed close to one another without creating an obstruction.<br>
    <br>Another popular application of flex pcb technology is in the manufacture of stackup and stackback systems. As the name would suggest, backup systems involve the manufacturing of a large array of identical PCB’s stacked together in a manner which allows them to be pulled down or disconnected from one another. Typically, this is accomplished by “pulling” individual PCB’s down using mechanical pressure. The pull down system is commonly implemented in conjunction with an emulator, which cuts the conductors at the contact points. The stack can then be attached to the various components according to their placement on the assembly line.<br>
    <br>One of the most unique aspects of flex layers is that the actual circuit design itself does not have to be especially complicated. Typically, there is a flex layer with a thin, but prominent edge. This edge then becomes the substrate over which the individual components are built. In this way, the use of flex layers opens up a whole new world of design possibilities, because the edge of the flex layer can actually be designed as part of the circuit, in a manner very much like an integrated circuit. The flex layer can provide a flexible route for power to travel, which can help to optimize battery charging times.<br>
    <br>Finally, flex pcb manufacturers are beginning to utilize what is called a “stitch-and-glue” process. With this process, the board manufacturing company creates a pattern of wires or strands that are then glued into place using a solder-based adhesive. This method allows for the flex layer to be installed in a variety of different formations, depending upon the manufacturer’s design requirements. After the individual components are soldered and firmly placed into position, the board can then be subjected to a second process called “set peening.” This second process essentially seals the edges of the flex layer, so that it cannot move around. Although this process requires greater manual dexterity, it has been found to yield significant cost savings, increased reliability, and higher durability than the previous methods.<br>
