The Increasing Complexity of Electronic Devices
As electronic devices become more sophisticated and complex, the demand for high-quality PCB assembly services has also increased. Modern electronic devices require PCBs with higher density, smaller form factors, and better performance, which can only be achieved through advanced PCB assembly techniques.
High-Density Interconnect (HDI) PCBs
HDI PCBs are becoming increasingly popular in the US market due to their ability to accommodate a large number of components in a small form factor. HDI PCBs use fine-pitch surface mount technology (SMT) components and micro vias to achieve higher density and better performance. According to a report by Global Market Insights, the US HDI PCB market is expected to grow at a CAGR of 8.5% from 2021 to 2027.
Flexible and Rigid-Flex PCBs
Flexible and rigid-flex PCBs are also gaining traction in the US market, particularly in applications that require flexibility, durability, and reliability, such as wearable devices, medical implants, and aerospace systems. These PCBs use flexible substrates and advanced assembly techniques to achieve the desired performance characteristics. A report by Markets and Markets projects that the US flexible and rigid-flex PCB market will reach $4.2 billion by 2026, growing at a CAGR of 7.9% from 2021 to 2026.
The Need for High-Quality, Reliable PCBs
The increasing demand for high-quality, reliable PCBs is another factor driving the growth of the PCB assembly market in the US. As electronic devices become more critical in various applications, such as healthcare, aerospace, and defense, the need for PCBs that can withstand harsh environments and meet stringent quality standards has become paramount.
IPC Standards
IPC (Association Connecting Electronics Industries) is a global trade association that sets standards for the electronic interconnect industry, including PCB design, fabrication, and assembly. IPC standards ensure that PCBs meet the required quality and reliability standards for various applications. In the US, IPC standards are widely adopted by PCB manufacturers and assembly service providers to ensure that their products meet customer requirements and industry standards.
Quality Management Systems
PCB assembly service providers in the US are also implementing quality management systems, such as ISO 9001 and AS9100, to ensure that their processes and products meet the highest quality standards. These systems help to identify and eliminate potential quality issues, improve process efficiency, and enhance customer satisfaction.
PCB Assembly Techniques
To meet the growing demand for high-quality PCBs, PCB assembly service providers in the US are adopting advanced assembly techniques, such as surface mount technology (SMT), through-hole technology (THT), and mixed technology.
Surface Mount Technology (SMT)
SMT is a popular PCB assembly technique that involves placing and soldering surface mount components directly onto the PCB surface. SMT offers several advantages over THT, such as higher component density, smaller form factors, and faster assembly times. According to a report by Research and Markets, the US SMT equipment market is expected to grow at a CAGR of 5.6% from 2021 to 2026.
Through-Hole Technology (THT)
THT is a traditional PCB assembly technique that involves inserting component leads through holes in the PCB and soldering them to pads on the opposite side. Although THT is being replaced by SMT in many applications, it is still widely used for components that require higher mechanical strength, such as connectors and power components.
Mixed Technology
Mixed technology PCB assembly involves using both SMT and THT techniques on the same PCB. This approach allows for greater flexibility in component selection and placement, as well as improved reliability and performance. Mixed technology PCB assembly is becoming increasingly popular in the US market, particularly in applications that require a combination of surface mount and through-hole components.
