Why Backing Plates Matter

  • Dissipate Heat – Copper pulls heat away from the target to prevent overheating and stabilize deposition
  • Provide Support – Reinforces brittle target materials under high-energy ion bombardment
  • Ensure Electrical Contact – Maintains consistent current flow for uniform plasma and thin-film quality
  • Reusable & Economical – Plates can often be cleaned, rebonded, and reused—saving cost and material

Why Forged is Better

  • Refined Grain Flow → Stronger, more conductive, and longer-lasting
  • Durability Under Stress → Withstands thermal cycling and mechanical loads
  • High Purity, High Conductivity → Stable, reliable deposition performance
  • Consistent Bonding Surface → Ideal for indium, elastomer, or diffusion bonding
