Application Case: Copper C110 EV Busbar and Power Electronics Terminal

Application context

Busbars and terminals need conductivity, hole quality and burr control. The material may look simple, but copper machining and plating decisions strongly affect performance.

This is an application case playbook, not a fabricated customer success story. It describes the engineering information a buyer should prepare and the manufacturing route FabVector would evaluate before issuing a firm quote.

Suggested manufacturing route

• Machine holes, slots and contact faces with controlled deburring.
• Review bend, plating or assembly operations if they happen after machining.
• Inspect contact surfaces and mounting holes after finish when plating is applied.

Material and finish decisions

• C110 copper for conductivity.
• Tin plating for solderability or contact behavior when required.
• Nickel barrier layers when corrosion or diffusion concerns exist.

Quality and risk controls

• Burrs around holes can compromise assembly and electrical contact.
• Soft copper can deform under clamping.
• Plating changes hole diameter and contact face thickness.

What to include in the RFQ

• Copper grade, conductivity target and plating requirement.
• Current path, contact areas and burr limits.
• Hole tolerance, flatness and assembly sequence.
