PCBs, or printed circuit boards, have become nearly universal, used in most of the electronics we use and love today. For example, PCBs are used in cell phones, in computers, and in televisions. They have also been widely integrated over the past few decades into traffic lights across the U.S. and North America as a whole. They have nearly endless applications, and innovation involving printed circuit boards is constant. Circuit board prototyping continues to develop, grow, and diversify with technology.

PCB design can diverge in a few different ways . For example, there are different types of circuit assemblies for printed circuit boards: an integrated circuit, or microchip, and a hybrid circuit. Each type of printed circuit board is designed specifically for that use. There are also different ways to actually print the legend for the fully printed circuit board prototype, including silk screen printing and liquid photo imagining. Ink jet printing is another option. The legend is a crucial part of the printed circuit board, containing component designators, switch settings, and test points. These things help in the assembling and testing phases of circuit board prototyping. Design varies among PCBs and circuit board prototyping needs to be precise.

For example, a prototype PCB manufacturer needs to be cautious, as it’s been proven that PCB failure is rooted primarily in environmental stresses or problems caused by the manufacturer during production. Precision is important as a surface mounted printed circuit board can be manufactured to be as small as a mere one-tenth the size of through-hole circuits. Precision can be helped by the use of framed stencils, which have smooth aperture walls and can be used for 16 Mil pitch and smaller.

Printed circuit boards are on the rise. The global circuit board market is climbing, expected to reach over $70 billion by 2022, just a few short years away. Market research has also predicted that the global PCB market will grow at a CAGR of 3% by 2020.

Printed circuit boards are integral to the technology we use, love, and depend on today. Without printed circuit boards, cell phones would not be what they are. Nor would computers, or street lights, or virtually any technology you could think of. Printed circuit boards are truly exciting things, but need to be executed with precision, attention to detail, and an eye for innovation. After all, when it comes to technology and circuit board prototyping, we must constantly keep improving and pushing forward.
