Delta Press-Fit Smart Machine Leverages Advanced Pressing Technology, Making it a Superb Teammate for the PCBA Industry
Printed Circuit Board Assembly (PCBA) refers to the sector involved in the manufacturing and assembly of PCBs with electronic components. Traditionally, components such as resistors, capacitors, and ICs are soldered onto the PCB, which involves a wide range of techniques and complex procedures. With the continuous evolution of the electronics industry, including advancements in IGBT, communication components, and power elements, the PCBA sector is driven to develop and adopt new technologies for production efficiency and quality enhancement.
Soldering and Press-Fit are two main technologies for connecting electronic components to PCBs. Soldering is a mature technology widely used, however, the high temperatures generated during the process can potentially damage components or the PCB itself. What’s worse, the use of solder and flux can pose environmental pollution issues. On the other hand, Press-Fit technology involves pressing metal pins into PCB holes, creating mechanical force that ensures a secure contact and stable electrical connection. This method eliminates the need for solder and flux, thereby avoiding heat-induced component damage as well as meeting environmental requirements.
Nowadays, the growing automotive electronics and server industries are utilizing Press-Fit technology extensively. However, the pressing process still faces challenges such as uneven pressing force, misalignment, bent pins, and reliance on manual insertion of blocks. To help customers overcome these issues, Delta has specifically developed the Press-Fit Smart Machine for the PCBA industry. This high-precision machine ensures stable force and can monitor the pressing process in real time for quality control while recording production parameters comprehensively. Coupled with alignment tools or machine vision systems it can achieve precise positioning. The machine also features a dynamic frame limit function to detect bent pins and offers automated operations for loading, fixture changing, and inspection. Recently, Delta assisted a PCBA manufacturer in northern Taiwan by introducing several Press-Fit Smart Machines into their server production line. The machines resolved their previous pain points of relying on manual operation and poor pressing quality, while achieving increased yield rates and reducing rework rates.
Delta’s Smart Press-Fit Machine offers the following benefits:
- Reduced pressing errors and enhanced yield rates
In the PCBA process, bent pins are a common yet serious issue that can lead to poor electrical contact, short circuits, or even PCB failure. By adopting the dynamic frame limit function along with recipe parameters, the system can detect and identify pressing anomalies during and after the process, allowing real-time monitoring of quality changes.
- Real-time process monitoring and tracking for comprehensive analysis
Detailed recording of process data provides a production history, with data storage of up to 2,000 records per second. This cast, comprehensive amount of data helps users in curve monitoring, data tracking, and analysis.
- User-friendly interface for smart process management
The built-in graphical guidance feature not only records and programs pressing positions but also provides convenience. The full-color touch screen displays pressing information on one page, facilitating recipe management and application integration.
The importance of Press-Fit in modern electronic pressing has increased considerably. Leveraging this core technology, Delt'as Press-Fit Smart Machine not only ensures precise force control and rapid response time, but also meets high reliability and environmental requirements. It is a solder-free, leadless, and highly automated machine for the PCBA industry.
