The Trends of PCBA Manufacturing

By Casey Zhai

The latest technological innovations such as 5G connectivity, IoT sensors, and artificial intelligence are giving PCBA manufacturing a big boost, but there are still challenges to address.

In the past, manufacturing circuit boards was done using additive or subtractive methods. But product designers and contract manufacturers quickly recognized the benefits of using both types in a hybrid process. The fast turnaround of the additive method coupled with a robust subtractive process allows for the construction of reliable and repeatable electronics. Manufacturing steps have steadily advanced and complex PCBA can now be produced.

PCBA

Trend #1: Automation and Robotics

There are three distinct steps in the process of making circuit boards: procurement of components, assembly, and fabrication. Nevertheless, various procedures are open for by far most of the means, and board quality and speed of board turn are crucial components for your CM’s choice of strategy. A few manufacturers have reduced their reliance on manual skill and increased their interaction mechanization as a result of their efforts to improve these measurements. This trend is likely to grow as programmable robots reduce or eliminate common errors while simultaneously improving precision and agility. To exploit this progression, the plan decisions you make should be in a state of harmony with the DFM and DFA of your CM to capitalize on handling, speed, and yield rates.

Trend #2: Programming Based Handling and IoT

Inseparably with expanded computerization is more programming usage. Also, fabricating offices take on industry 5.0 practices for information trade inside and between offices. There are many benefits to programming based PCBA producing, particularly for gathering. Operators no longer have to physically handle boards thanks to quality control measures like automated optical inspection, which can spot defects or contamination that would otherwise go unnoticed by human visual inspection. The layout of IoT boards must be optimized for wireless interconnectivity and sensor data acquisition. You can better prepare for the future by emphasizing these skills now.

Trend #3: Engineer-Manufacturer Integration

The significance of engineers adhering to the CM’s DFM, DFA, and DFT construction guidelines when building boards is well-known to almost everyone involved in PCBA development or production. Nevertheless, it is essential that your CM comprehends your plan’s purpose and is aware of constraints for decisions that may work on assembly but adversely affect execution. Engineer-CM integration, also referred to as white-box integration, facilitates partnerships and dependability with a preferred manufacturer. instead of making each board assemble an undertaking.

Trend #4 On-Solicitation Creation

Before the new insecurity that affected the PCBA business, various planners and makers chose to use lean collecting practices to additionally foster reality and foster their slice of the pie. This frequently necessitated a just-in-time (JIT) strategy based on the erroneous belief that manufacturing capacity, materials, and components would never fall below a level that could disrupt the PCBA development process.

This suspicion has been dispelled by the electronic component flaws and other instances. As a result, specialists and CMs are developing organizations that include stocking standard components and materials for the construction of situation-specific sheets. Due to component shortages, the process of selecting components has also received more attention. No longer is having a favorite part enough. In order to prepare for production network interferences, it makes sense to include a variety of component choices.

Printed Circuit Board Assembly

Trend #5: Management of Supply Chain

Perceiving the need of an arrangement for production network the executives is another new however huge pattern. Because they rely on third parties to complete the entire turnkey manufacturing process. Most developers prefer CMs because they are either fabricators or assemblers. In most cases, this service is significantly faster than managing multiple manufacturing and assembly facilities. Because it provides a single assembly contact who is responsible for the entire process. Architects and CMs cooperate to accomplish viable inventory network the board, which might incorporate stocking parts, giving wholesalers need, and keeping away from fascinating parts.

Trend #6: Flexible PCBA

The rise of miniaturized electronic products with unconventional packaging has given flexible printed circuits a huge market share in the PCBA industry. They can bend and adapt to strange shapes and sizes. Flexible printed circuit boards can work consistently in high temperature environments. The reliability and lightweight of this board make it a suitable choice in the fields of aerospace, medical, automotive, and commercial electronics.

Flexible printed circuit boards are promoting thinner and lighter structures, suitable for printing techniques using additive processes. The materials and technologies used in flexible PCBA manufacturing have made significant progress, but the increase in material costs and complex assembly procedures are key challenges. They need a suitable storage facility, otherwise they are easily damaged. Repairing flexible printed circuit boards is both difficult and expensive.

Trend #7: High Power PCBA

The rapid consumption of Non-renewable resource and its impact on the environment highlight the importance of clean energy. High power PCBA are used in applications such as solar converters and electric vehicles. The typical voltage requirement is approximately 24V or 48V for solar panels, and 280V or 360V for electric motors. They are also used in heavy-duty machinery, transformers, and other power circuits.

When designing high-power PCBA, some issues are excessive heat dissipation, user safety, and product durability. These PCBA are thicker and include heavy copper traces to support high voltage designs. To avoid overheating, it is necessary to estimate power demand and design appropriate airflow. Suggest adding a fault protection circuit. To ensure quality performance, follow industry standards for high-power design.

QUESTION 1: What is the purpose to know the trends of PCBA?

It is necessary to understand the current trends and challenges in the PCBA manufacturing industry in order to increase production and generate revenue. PCBA designers and manufacturers must receive training based on their domain knowledge. Evaluating consumer needs based on trend technology can strengthen your product strategy and roadmap. In addition, by understanding potential issues, you will prepare for unexpected events and reduce the cost and time of product launches.

QUESTION 2: What do we need to pay attention to PCBA in IOT devices?

IoT devices use batteries; Therefore, the design of the power circuit is the key to this PCBA. The power consumption of each block should be estimated and maintained to extend battery life. In addition, the network connectivity of IoT devices exposes them to potential data theft, making it crucial to implement encryption algorithms and add security features at the PCBA level.
