Surface Mount Technology (SMT) and Conventional Plated Through-Hole Technology (PTH) or  Conventional Through-Hole Technology (THT) or are two different methods of assembling components on a printed circuit board (PCB). Each has its advantages and disadvantages, and the choice between them depends on the specific requirements of a project. Below are the pros of SMT and PTH:

The PCB Manufacturing Process

Surface Mount Technology (SMT):

  • 1

    Miniaturization: SMT components are generally smaller and more compact than their through-hole counterparts. This allows for higher component density on the PCB, making it suitable for smaller, lightweight devices.

  • 2

    Lower Production Costs: SMT allows for automation, reducing labor costs and enabling faster production. This technology is well-suited for high-volume manufacturing.

  • 3

    Better Electrical Performance: SMT components have shorter lead lengths, which result in reduced parasitic capacitance and inductance, leading to improved electrical performance, especially at high frequencies.

  • 4

    Weight Reduction: SMT components are lighter and require less material, making them ideal for portable and lightweight electronic devices.

  • 5

    Improved Heat Dissipation: SMT components are typically mounted on both sides of the PCB, which can enhance heat dissipation. This is particularly advantageous for power electronics.

  • 6

    Enhanced Aesthetics: SMT components allow for a sleek and compact design, often preferred for consumer electronics and aesthetically appealing products.

Conventional Plated Through-Hole Technology (PTH):

  • 1
    Mechanical Reliability: THT components are mechanically anchored through holes in the PCB, providing excellent resistance to mechanical stress and shock, making them ideal for rugged applications.
  • 2
    Ease of Prototyping: THT components are easier to solder manually, making them suitable for prototypes, small-batch production, and hobbyist projects.
  • 3
    Better for High Currents: THT components are better suited for high-current applications due to their robust mechanical connections.
  • 4
    Accessibility for Repairs: THT components are easier to remove and replace when repairs or upgrades are needed.

In summary, the choice between SMT and THT depends on the specific requirements of the project, including factors such as component size, volume of production, mechanical stress, and electrical performance. Many modern PCBs utilize a combination of both technologies, known as mixed-technology PCBs, to leverage the strengths of each method for optimal results.

The Art and Science of PCB Manufacturing

Printed Circuit Boards (PCBs) are the backbone of modern electronics, serving as the critical connection between electronic components and enabling the functionality of countless devices, from smartphones to spacecraft. PCB manufacturing is a complex and precise process that marries technology and craftsmanship. In this article, we’ll take a closer look at the steps involved in PCB manufacturing and the technologies that make it possible.

The PCB Manufacturing Process

  • 1

    Component Sourcing: PCB assembly begins with the acquisition of electronic components. These components can range from resistors and capacitors to advanced microprocessors and sensors. The procurement team works to ensure a steady supply of quality components, often collaborating with trusted suppliers.

  • 2

    Stencil Printing: The first step in assembling a PCB involves applying solder paste to the PCB’s surface. A stencil, which is a thin, perforated metal sheet, is used to precisely deposit solder paste onto the board. This paste will later be used to attach the components.

  • 3

    Pick and Place: Once the solder paste is in place, an automated machine known as a pick and place system takes over. This machine accurately picks up each component from their respective feeders and places them on the PCB, guided by the design data. These machines can place thousands of components per hour with incredible precision.

  • 4

    Reflow Soldering: After component placement, the PCB goes through a reflow soldering process. The PCB is heated in an oven, causing the solder paste to melt and create strong, permanent connections between the components and the board. The temperature and time profiles are carefully controlled to avoid damaging sensitive components.

  • 5

    Inspection and Quality Control: Quality control is paramount in PCB assembly. Automated optical inspection (AOI) and in-circuit testing (ICT) are often used to ensure the correct placement and soldering of components. This step helps identify and rectify any defects in real time.

  • 6

    Hand Assembly (if required): In some cases, PCBs may require manual assembly for specialized components or intricate designs. Skilled technicians assemble these components with the utmost care and precision.

  • 7

    Cleaning: To remove any residues left by the soldering process, the PCBs are cleaned. This is particularly important for sensitive applications where even a tiny residue can affect performance.

  • 8

    Conformal Coating (if required): Certain PCBs, especially those intended for harsh environments, receive a conformal coating to protect against moisture, dust, and other contaminants. This protective layer extends the PCB’s lifespan and reliability. To find out more view our conformal coating click here

  • 9

    Final Testing: After assembly and any additional processes, the PCB undergoes final testing to ensure its functionality. This involves powering up the PCB and running it through various tests to verify its performance against the specified criteria.

  • 10

    Packaging and Shipment: Once a PCB assembly passes all tests, it is carefully packaged and prepared for shipment. The PCBs are typically packed in anti-static bags and may include relevant documentation.


The assembly of PCBs is a sophisticated process that demands a combination of advanced machinery, meticulous craftsmanship, and stringent quality control. In today’s fast-paced electronics industry, PCB assembly has become more efficient and accurate than ever before, enabling the creation of complex and powerful electronic devices that enhance our daily lives.

As we look toward the future, PCB assembly will continue to evolve in response to new technologies and market demands. Innovations such as miniaturization, increased component integration, and environmentally friendly manufacturing processes are sure to shape the industry. PCB assembly is not just a crucial step in electronics manufacturing but also an art in itself, driving progress and innovation in our connected world.
