Tinning junction box contacts

INDUCTION - Electronic

Ensuring Reliable Electrical Contacts in Solar Junction Boxes with Induction Tinning

Discover how induction tinning ensures reliable electrical connections in solar panel junction boxes, offering a repeatable, automatable solution for a rapidly growing industry.

Induction tinning of solar junction boxes is essential for ensuring high-quality electrical contact. With the increasing demand for solar panels, it is crucial to adopt tinning processes that guarantee repeatability and reliability. Induction heating technology provides a precise and fast solution, which is vital for large-scale production.

Precise thermal control and consistent quality, eliminating defects and enhancing the reliability of electrical connections.
PTT (power, time, temperature) programs ensure absolute repeatability, delivering consistent and high-quality results.

Information about tinning electrical contacts in junction boxes.  

Induction tinning of junction boxes provides an advanced technological solution for ensuring durable electrical connections. By utilizing a high frequency induction generator, the process is optimized for maximum efficiency and quality, which are essential for the renewable energy sector.

This application involves the soldering of electrical contacts inside a junction box used in solar panels. The process ensures efficient and consistent tinning, critical for the renewable energy sector.

Details of the soldering process:

  • Generator used: Platinum HF2 (high frequency with 2.5 kW)
  • Tinning time: 2.1 seconds
  • Tin alloy: Pre-deposited on the contact strips
  • Inductor: Single-turn, closed inductor
  • Temperature monitoring: Not required

By developing specialized equipment, this process can be integrated into an automated production line, increasing efficiency and ensuring consistent quality in tinning operations, meeting the high standards of the renewable energy market.
