APPLICATIONS OF TECHNOLOGY:
- Sensor array development
- LED strips
- Power supplies
- Low production cost
- Locking design allows for mechanical robustness
- No components need to be soldered
- Vibration-resistant connector
- Electronic applications such as sensor arrays and LED strips require narrow cascaded printed circuit boards (PCBs). However, current solutions for interconnecting boards involve connectors or board-to-board soldering and therefore have a host of disadvantages (e.g., labor intensive, mechanically unreliable, expensive, often require too much board space). To overcome such limitations, a new board-to-board connection technique was developed.
Researchers at Berkeley Lab have developed a novel method to interconnect PCBs. This technique does not require any components or soldering.
All designs were manufactured and tested through the development process, and contact resistance was monitored as a function of stress factors (e.g., temperature, mechanical) to ensure continuous operation. The final solution was selected for its reliability, ease of assembly, and connector locking. Through this PCB design, the board itself can be used as a connector. Notably, the design can be used for high-current applications and high-voltage applications and allows perpendicular board stackups.
The technique provides a low-cost alternative to common connector technologies. It exhibits greater mechanical robustness than do previous methods, and it allows for ultra-narrow PCB designs. This is especially useful in applications where cascaded PCBs have to be placed in narrow tubes.
