When it comes to PCB (printed circuit board), a lot of people think of rigid PCB. But a PCB can refer to either a rigid PCB or a flexible PCB, and many customers feel confused about the difference between rigid PCB and flexible PCB. However, rigid PCBs have the same ultimate function as flexible PCBs, which is connecting various electrical and mechanical components together Now PCBGOGO will explain which one is best for your electronic project.
When designing rigid PCBs, certain design rules must be followed, including minimum hole sizes, minimum space and trace width, minimum distances to board edges, and copper and overall design thicknesses. Additionally, many manufacturing process steps are shared between rigid and flexible PCBs. Such process steps include the drilling and plating of holes and vias, photo imaging and development, the etching of copper traces, pads, outlines, and planes, and the heating (baking) of the circuit boards for the purpose of removing moisture from the PCBs. At this point in the manufacturing process, rigid PCBs head to the solder mask station while flex circuits go to the coverlay station.
No matter where in the case of possible rectangle should be preferred , because it can save a good base . Near the edge of freedom should allow sufficient margins , depending on the substrate may be the remaining space.
If an assembly will be exposed to excessive or repeated shock, or high vibration environments, connectors with flexible cables are more likely to fail. Rigid flex PCBs provide great reliability even when subjected to extreme vibration and shock applications. Check this link right here now https://www.pcbonline.com/support/Rigid-Flex-PCBs
