Press-fit

High-Yield Press-Fit: Beyond Just Pressing

Press-fit is a manufacturing process that enhances the design of connector terminals. It involves the precise control of pressure, speed, and positioning using specialized equipment to firmly insert connector terminals into PCB holes, ensuring stable contact and conductivity without heating. This eliminates common issues such as uneven heating during the soldering of thick PCBs or poor DIP solder height, which are fundamental manufacturing challenges. This technology finds extensive application, particularly in high-speed signal transmission environments and intricate and compact circuitry design.

This method guarantees a high level of connection stability and is particularly suitable for delicate components. It is widely employed in industries demanding exceptional reliability, including automotive, aerospace, and industrial control sectors.

  • Product Insight as the Key to Press-Fit Efficiency

Press-fit products are commonly used in electronic components such as PCBs, connectors, IGBT modules, and Power Elements. Each component requires specific press-fit parameter settings to ensure proper functioning.

For instance, when press-fitting connectors for optical communications, it's crucial to consider the force points to prevent the housing from warping or deforming. In producing IGBTs, there are two distinct scenarios: IGBTs with built-in thermal columns or fins must be fully press-fitted. At the same time, those using conductive cooling should maintain a specific press-fit height to ensure adequate thermal transfer without being too tight against the PCB.

A press-fit manufacturer who understands the characteristics of its products can enhance production yields and help clients minimize losses.

  • Fixture Design's Impact on Press-Fit Yield

Press-fit tooling requires specialized designs that are customized according to the PCB layout and the structure of the connector. This ensures stable support and clearance. Additionally, the force-receiving surface plays a crucial role in the press-fitting process for various products. For instance, when backplane connectors are press-fitted, an optimized force-receiving surface can prevent issues such as pin collapse, pin protrusion, and connector deformation, thus ensuring a smooth press-fit process.

  • Considering Software Interfaces Beyond Hardware

Press-fit stations are crucial in the assembly process, and their integration with each assembly plant’s job ticketing and the Manufacturing Execution System (MES) is vital to capturing and linking manufacturing data. Job order barcodes should integrate press-fit metrics like yield rates, unit counts, and labor hours for seamless data reporting.

For smooth operation, operators require an intuitive software interface. This should include clear instructions on the press-fit sequence, visual positioning aids, and readouts of the press cycle to enhance efficiency. Additionally, equipment should have features for rapid programming and easy troubleshooting to keep it running smoothly.

  • Optimizing Production Workflows for Enhanced Flexibility

Press-fit technology is revolutionizing the manufacturing industry by making the process more efficient and cost-effective. PCBs can now be repeatedly reconnected, simplifying manufacturing and repair processes while eliminating the need for soldering-related cleaning. This reduces maintenance costs and eases the load on production lines.

Moreover, this technology boosts design versatility by bypassing the need for solder, enabling versatile component placement within space-constrained devices, and greatly increasing PCB design flexibility.
