Introduction to Quick Turn Circuits
In the fast-paced world of electronics design and manufacturing, time-to-market can make or break a product's success. Quick turn circuits have emerged as a critical solution for engineers, designers, and manufacturers seeking to rapidly prototype, test, and produce printed circuit boards (PCBs) with unprecedented speed and efficiency.
The Evolution of PCB Prototyping
Historically, PCB development was a time-consuming process that could take weeks or even months. Traditional manufacturing methods involved multiple design iterations, lengthy fabrication times, and significant financial investments. Quick turn circuits have revolutionized this landscape, enabling almost instantaneous transformation of design concepts into functional prototypes.
