Off to the Races: Creating Winning Finishes

As promised, we are off to the races, untangling the convoluted subject of PCB surface finishes.  This is a complicated subject, so bear with me as I try to break it down into bite-sized, manageable portions! This week I will discuss each available surface finish and the pros and cons of each one.

Picking Prepregs For Peak Performance

Multilayer printed-circuit boards (PCBs) have gained in popularity as designers seek to shrink their circuits. They offer the opportunity to stack a wide range of functions on one multilayer design, even combine analog, digital, and microwave circuits on a single circuit assembly. Designers have learned how to stack laminates with different relative dielectric constants, such as PTFE-based laminates and FR-4, in compact multilayer circuits, but creating such circuits requires careful planning and a good understanding of the role that bonding films and prepregs play in multilayer circuits.
