The world of printed circuit boards (PCBs) is filled with fascinating innovations, surprising statistics, and remarkable technological achievements. Advanced Circuits, a pioneering force in the PCB industry since 1989, has been at the forefront of many groundbreaking developments that have shaped modern electronics. From revolutionary manufacturing processes to mind-boggling market statistics, the PCB industry continues to surprise even seasoned professionals with its rapid evolution and technological prowess.
The Revolutionary History of Advanced Circuits
From Humble Beginnings to Industry Leadership
Advanced Circuits began its journey in 1989 with a clear mission: to lead the PCB industry in quality and innovation. The company's evolution represents one of the most compelling success stories in the electronics manufacturing sector. Since 1989, Advanced Circuits has been leading the PCB industry in Quality and Innovation for prototype through large scale production manufacturing and now provides full assembly capabilities.
What makes Advanced Circuits' story particularly interesting is their strategic pivot in the early 1990s. Rather than competing with large-scale manufacturers for high-volume orders, the company made a brilliant strategic decision. His conclusion was that Advanced Circuits should concentrate on prototypes, which were needed quickly in limited quantities and often required clarification on design specifications, a factor that played to the company's advantage in language compatibility. In the words of Huston, "We stopped fishing for whales and started fishing for minnows."
This strategic shift proved to be revolutionary. In November 1992, the company sent out 5,000 brochures to potential customers, making a bold promise that would become their trademark: boards would be delivered on time or they were free. This guarantee became the foundation of their rapid growth and industry reputation.
The "$33 Each" Revolution
One of the most interesting facts about Advanced Circuits is their introduction of the famous "$33 Each" special in summer 2001. Advanced Circuits introduced the famous "$33 Each" Special that made quickturn, small quantity PCBs affordable to not only all professionals, but also hobbyists and students alike. This pricing innovation democratized PCB prototyping, making it accessible to a much broader audience including students and hobbyists who previously couldn't afford professional-grade PCB manufacturing services.
