Hybrid PCBs
Certain manufacturers mix laminate materials to create hybrid systems. One popular variant is rigid flexible PCBs.
These are PCBs that have both rigid and flexible circuits are incorporated into a hybrid package that offers the benefits of flexible circuits as well as traditional PCBs. Certain parts are flexible which allows the board to bend into shape or stretched out thousands of times without affecting the continuity of electrical power. Others are rigid, allowing for the greater electrical routing density needed for contemporary electronic circuits.
Flexible flex boards often be the ideal packaging method for the current generation of electronic engineers.
Another popular hybrid option is to incorporate layering of Teflon materials inside a traditional polyimide PCB or
FR4. The Teflon layers offer the electronic designer layers designed for high-speed signals, in an overall PCB that is manufactured.
Low and No-Flow Prepregs
One component that is crucial to the manufacturing of rigid flex board is a low or no flow prepreg. Preparing no flow prepregs is done slightly like conventional prepregs. However, the resin is moved to a higher level of cure. This creates an uncured sheet which allows the resin to flow slightly however, not much. As with conventional prepregs the resin has reached an appropriate temperature the resin will melt and then harden.
In rigid flex circuit boards manufacturing, low and no flow prepregs are essential since they allow the flow of resin until the end of the portion of the board, but without spilling out onto the flexible portion that makes up the rest of the panel. If rigid flex makers used traditional prepregs, the resin would spill over the flexible section making them rigid. Low flow or no flow prepregs are often used to glue components to PCBs, such as stiffeners and heat sinks for flexible circuits because the rate of flow of resin is controlled and desirable.
Low flow and no flow prepregs are very scarce and designers should when creating a rigid flex board be sure to select the laminate system that comes with a none flow prepreg. Manufacturers of rigid flex cannot utilize conventional prepregs for rigid flexible design. Additionally, low and no flow prepregs can be limited in their use with heavier copper weights, as the resin doesn't have enough flow to adequately encapsulate circuitry. They also have specific manufacturing issues that must be taken into account to make them work effectively.
