Sierra Circuits: Micro-Electronics PCB Division

In 2005 Sierra opened a new Microelectronics Division to serve the fast growing need for really small, complex PCBs for the Microelectronics market. This division provides PCBs with less than 2 Mil (0.002") lines and spaces.

The Bleeding Edge: Designing Microelectronic Printed Circuits

"...the world of electronics is about to explode or, should I say "implode," the definition of which is "to collapse inward, violently." This implosion will be driven by a serious size reduction or, huge improvements in the functionality of electronic products, resulting in the miniaturization of the printed circuit board..." (more)
