Did you know that the first electric cars were produced during the mid- to late-1900s? Moreover, electric cars were in fairly common usage before gasoline engine automobiles. However, in the early twentieth century, the tide turned and Henry Ford and others took over the automobile industry. The history of electric vehicles is just one in which technology was developed, but not fully embraced at the time, only to resurface later with much wider acceptance. It is certainly true that in some cases, timing is everything!
The speed of technological advancement
Today, it seems as though technological advancement moves almost at the speed of light. This is especially true for electronics and PCBAs, which are the driving force behind much of the advances. The demands for greater functionality, more versatility, and smaller size, along with the traditional thrusts for cheaper and faster production necessitate that you are aware of where the PCB market is headed. With this goal in mind, let’s take a look at what’s new in applications of printed circuit boards and their manufacture.
What’s New in Applications of Printed Circuit Boards?
Printed circuit boards or more accurately assembled printed circuit boards (PCBAs) are everywhere today. Common applications include consumer electronics, medical devices, industrial equipment, aerospace systems, automotive, telecommunications, security and safety systems. Due to the wide range of board types, such as high-speed, high power, HDMI, micro PCBs, and non-standard form factors, virtually all industries include electronic devices for monitoring, measurement, control, and communication. In addition to these common applications, recent board developments have emerged for specialized usage as listed below.
PRINTED CIRCUIT BOARD APPLICATIONS
|Residential, medical and storefront lighting||Made from aluminum for fast heat dissipation||LED boards with a metallic substrate|
|Medical instruments, consumer products, surveillance equipment||Complete very small cameras that can be mounted on virtually any-sized board||Miniature PCB cameras|
|HDI, complex designs||Use of stacked in-pad vias to provide connectivity on all layers.||Every Layer Interconnect (ELIC)|
|Gauges, antennas, sensors||Substrate and trace layout created by additive manufacturing or 3D printer||3D Printed Electronics (PEs)|
|Space-based internet constellation||Large group of satellites (thousands) for integration in space to achieve a common mission||Satellite on a single PCB (Sprite)|
The first three PCBA types are currently in use, while the latter two are still in development, although a number of constellation satellites, known as Starlink, have already been launched. It is expected that all of these board types will increase the range of applications of printed circuit boards.
What’s New in the Manufacturing of Printed Circuit Boards?
PCBAs are not the only area of circuit board development that is experiencing advancement. In fact, it may be that the way boards are manufactured is expanding at an even faster pace. Some notable manufacturing technologies that are or will significantly impact the industry are listed below.
|PRINTED CIRCUIT BOARD MANUFACTURING APPLICATIONS|
|Agile Manufacturing||Software-driven manufacturing that can be quickly modified to adapt to design changes||Any industry, but primarily applicable for critical industry applications, such as medical devices, aerospace, and industrial production|
|Internet of Things (IoT) Manufacturing||The gathering, processing, and distribution of data and information, typically wirelessly, to improve the efficiency of the manufacturing process||Can be used for all board development, but the greatest benefit is realized for traditionally long development processes|
|Sustainability Manufacturing||Manufacturing that seeks to minimize negative environmental impact, conserve energy and natural resources and increase the safety of employees, community, and product||Can be applied to any application; however, most relevant for high power consumption electronics|
|Green Manufacturing||Use of materials and chemicals that are not harmful to human or animal life, components and elements that are reusable||Biodegradable electronics, electronics recycling|
|Autoplacing||Merging of autorouting (ECAD) and pick-and-place (assembly) functions||Boards with complex routing schemes and dense component landscape|
All of the manufacturing advancements listed above have the primary objective of increasing the efficiency of board builds. And with the exception of autoplacing, all are being implemented today. Autoplacing, although promising in theory, has been limited as the best means of dealing with mechanical constraints is under study. However, the prospect of making the routing of board traces and component placement faster and simpler would be welcomed by any PCB designer or engineer.
