Innovations Driving the Future of PCB Assembly

Oct 06,2022 A printed circuit board assembly is no doubt an integral part of most electronic and electromechanical devices, and this segment of the electronics industry has gained huge traction over the years. For any industry segment to grow, ongoing research and evolution is necessary. Techniques used for PCB assembling, testing, and so on have evolved over the years and have also found increasingly advanced applications. There have been advancements in manufacturing and assembling techniques and processes as well in terms of automation, 3D printing, and so on. This is a continual process and further advancements over the next few years are imminent. This post discusses the advancements in Printed circuit board assembly techniques, applications, and more.
 
Reasons for Advancements in Printed Circuit Board Assembly
 
Here are a few reasons for advancements in PCBA manufacturing, assembling, and more in terms of techniques, use of materials, complex applications, and more.

• The demand for automation in industries, electronic devices, smartphones, smart devices, Internet of Things (IoT), AR/VR, and many other advanced technologies and smart equipment have subsequently risen the demand for advancements in PCBAs in all aspects. Hence, high-volume production using advanced processes is gaining importance.

• With more industries and sectors incorporating technology in their day-to-day functioning, the requirement for PCBs has also gone up. More so, most of these applications are complex and require extreme precision. These segments range from diagnosis equipment, monitoring devices, and devices with electronic ergonomic controls in the medical sector to navigation systems, spacecraft control systems, communication systems, industrial integrated systems in manufacturing units, sensors, power supplies, LEDs, and more.

• All the above aspects have shrunk the size of these boards, while increasing the number of layers, components, and functionalities. So, automation in PCB manufacturing, assembling, and testing took its natural course and became the need of the hour.

 
Advancement Trends in PCB Assemblies Over the Last Few Years
 
Single-sided PCBs were developed in the 1950s for use in devices such calculators. Since then, the timeline of PCBAs has witnessed continual growth and improvements. These advancements are at every stage of the PCB making process such as design, component mounting, advanced CNC machining techniques, component mounting BGA, soldering, layering, automation testing, and more. It also spans the types of PCBs such as HDIs, materials used, and more. Here are a few pointers regarding the same.
 

• HDI or high density interconnect PCBs are now widely used in mission critical segments such as medical devices, wearable devices, communication systems in defense, and more. They are small in size and provide high speed signals, clearer circuit path, routing options, and more.

• IoT or Internet of Things which facilitates device to device communication in a network requires complex PCBA. These include smart homes, smart meters, integrated systems in factories, virtual simulation systems, and smartphone applications for remote access and others

• Flexible PCBs which are a combination of flex and rigid boards are already widely used as they have properties of both the types.

•  High power boards with high voltage of up to 48volts capacity are now being widely used. This is only expected to rise with the increasing penetration of electric vehicles, solar panels, and so on.

• DFM or design for manufacturing is being widely implemented in PCB design and manufacturing processes. Testing techniques have also advanced which helps fix any errors in time. These include automated optical inspection (AOI), advanced in-circuit testing systems with cameras and x-rays, and so on.
