<p><strong>What is Flex PCB?</strong></p><p><br></p><p>The most commonly used and most commonly used type of printed circuit board is the rigid type, and the flexible type is another type that you may think of using when you are familiar, especially as more and more manufacturers provide this function, it is now It is easier to use than before.</p><p><br></p><p>In this article, we will understand what a flexible PCB is, where it can be used, why the cost is higher, and finally how to order a flexible PCB from a manufacturer like PCBway.</p><p><br></p><p>For the first impression, readers may think that PCB may only have two types, rigid or flexible, and there is a third hybrid type called <a href="https://www.atechpcb.com/pcb-manufacturing" rel="noopener noreferrer" target="_blank"><strong>rigid-<a href="https://www.atechpcb.com/pcb-manufacturing" target="_blank">flex PCB</a></strong></a>. A rigid-flex PCB is a circuit board having both a rigid circuit part and a flexible circuit part and they are laminated together. Flexible PCB is also called flexible circuit board or FCB.</p><p><br></p><p>The flexible board can be used as a connector or as a complete circuit assembled with components. Yes, it can retain welding heat, and depending on the type of film material used, it can last longer than high-temperature rigid welding.</p><p><br></p><p>However, if you select the "rigid-flexibility" option, you decide which layer in the design layer stack to choose as the flexibility.</p><p>The reason for the freedom to choose the position of the flexible layer is that the manufacturing process will be similar. Multiple layers will be built layer by layer.</p><p><br></p><p>Another first impression about a flexible PCB may be that it is only single-sided or double-sided, but in fact, flexible PCBs can be multilayered like usual rigid PCBs.</p><p><br></p><p><strong>The role of Thumb in </strong><a href="https://www.atechpcb.com/pcb-manufacturing" rel="noopener noreferrer" target="_blank"><strong>Flex PCB</strong></a><strong> design</strong></p><p><br></p><p>This paragraph will not explain all the functions of the thumb in the FPC design, but will rarely mention it so that the reader can understand what should be considered when using the flexible board. Some of them are even shared with rigid PCBs.</p>
