Advanced PCB Technologies and Services

Through-hole Technology (THT)

Through-hole technology (THT) is an electronic assembly technology contract manufacturers use to mount electronic components on a PCB. In THT, the electronic components have leads inserted through holes in the PCB and then soldered onto the opposite side of the board.

THT technology is commonly used for through-hole components, such as large capacitors, connectors, and power devices, which require a stronger and more reliable connection to the PCB. THT also allows for easy manual repair or replacement of components, making it a popular choice for products that need to be serviced or repaired.

One of the advantages of THT is that it provides a strong mechanical bond between the electronic components and the PCB, making it ideal for applications that require high reliability and durability. In addition, THT technology is generally less expensive than other assembly technologies, making it a cost-effective option for many products.

However, THT technology can also have disadvantages, such as limited design flexibility and the need for drilling holes in the PCB, which can increase manufacturing time and cost. As a result, electronic contract manufacturers often work with their customers to determine the best assembly technology for their specific product requirements, considering factors such as performance, reliability, cost, and design flexibility.

Box-build Assembly

Box-build assembly is an electronic assembly service offered by electronic contract manufacturers that involves the complete assembly of a final product or system, including the enclosure or “box” that houses the electronic components. This type of assembly service typically involves a wide range of activities, such as mechanical and electrical assembly, wiring, and testing. In addition, it may include a variety of sub-assemblies and components.

It can be complex and challenging, requiring expertise in component sourcing, supply chain management, design for manufacturability, and quality control. As a result, contract manufacturers that specialize in box-build assembly often work closely with their customers to understand their specific requirements and to provide customized solutions that meet their unique needs.

One of the key advantages of box-build assembly is that it can help reduce the time and cost associated with assembling and testing a final product, allowing the customer to focus on other aspects of their business, such as product design and marketing. It can also help improve the quality and reliability of the final product by ensuring that all components are assembled and tested to the highest standards.

However, it’s vital for customers to choose a reputable and experienced electronic contract manufacturing partner for box-build assembly, as the complexity and scope of the project can vary widely depending on the specific requirements. In addition, a skilled and knowledgeable electronic contract manufacturing partner can help ensure that the final product meets the highest quality and reliability standards and can help reduce the risk of costly delays or rework.
