Frequently Asked Questions

What is the conductivity of your copper busbars?

We use high-purity T2 copper (Cu-ETP) with IACS 100%+ conductivity — the industry standard for high-performance power distribution.

Can you customize size, shape, and bending?

Yes. We offer full customization — dimensions, bend angles, hole patterns, terminal placement, and lamination structure, engineered to match your exact module layout.

What surface plating options are available?

Standard options include tin (Sn), silver (Ag), and nickel (Ni) plating, selected based on your application, environment, and contact resistance requirements.

What is the lead time for a custom order?

Typical lead time is 1–2 weeks for samples and 3–4 weeks for volume production, depending on design complexity and order quantity.
