Clean Energy Assembly Solutions

When addressing the thin-film interconnect challenges of high-efficiency solar cells (such as TOPCon and HJT), thermo-mechanical stress control of the solder material is critical. Junjun Tech and Alpha provide you with an era-defining green assembly solution.

Core Empowering Advantages

  • Extreme wetting coverage: Ensuring uniform, low-resistance metallurgical bonding between copper ribbons and cell back surfaces.
  • Eco-friendly low-residue system: Halogen-free flux formula eliminating electrochemical corrosion in atmospheric environments.
  • Ultra-thin substrate support: Extremely short thermal history effectively suppressing thermally induced silicon micro-cracking.
