The standard thickness of PCBs is 1.57 mm . Some manufacturers will accommodate other specific thicknesses of 0.78 mm or 2.36mm. When we say "thick" or "thin" FR4, we're generally comparing to the standard thickness of 1.57 mm. As long as your manufacturer's process can handle it, you can choose any … See more Does your PCB have a strict form factor requirement, or does it need to fit into a very slim enclosure? Some designs require a thicker board to support heavier components, withstand mechanically rough environments, … See more Will the device have any components that require the printed circuit board to have a specific PCB thickness? Components like edge connectors and bulkier through-hole components like high current transformers require the PCB … See more If you are working with a high-speed device, FR4 is always not the best option, and some other low-loss material may be desirable. If the link length is short, then losses will be dominated by return loss at the load component, … See more The distance between a trace and its nearest reference plane (on an adjacent layer) determines the trace impedance, as well as the level of dielectric losses in multilayer boards. … See more how does nice hash make money
