It’s important to communicate with the PCB or flex application engineer during the beginning of any PCB design job and discuss everything you need or require for your project. Open and constant communication with your PCB provider ensures that you’re both on the same page, which can reduce the need for multiple extensive revisions.
While it is rare that a printed circuit board is 100% perfectly designed on the first try, communication will help ensure that your PCB is properly designed from the start and that any revisions are not major ones that will derail your project and timeline.
When you submit a design, you also need to have the right board size, trace width, materials, component placement, and tolerances. Plus, in the case of flex, you’ll need to determine whether the design is static, partly flexible, or dynamic.
It’s also important to consider the environment in which the product has to function. Is the printed circuit board or flex circuit designed for a non-extreme environment, such as your cell phone, or the highest of extremes, such as an explosion?
You’ll likely have questions about the PCB design and layout process, which means it’s best to find a reputable PCB provider with extensive engineering experience who can answer your questions and ensure a smooth project from start to finish.
A copper-clad substrate or polyimide-based film is often used for flex circuits, and FR4 (or an FR4 stiffener) is used for rigid-flex. FR4 allows you to build up the layers as the technology content is created.
A solder mask is also used, which is a technique where everything on the circuit board is coated with an epoxy-based LPI or cover coat for flex, except the contacts to be soldered, the gold-plated terminals of any card-edge connectors, and fiducial marks.
PCBs also include a legend application, which are the decals and reference designators in epoxy ink on a board. The name refers to the method of application in which the ink is automatically applied similar to ink jet printers
