CUNECTRA · TWO CORE PRODUCT LINES

Cu-Al Composite Busbars & PCB/SMT Precision Interconnects

Two core businesses: Cu-Al composites and PCB/SMT interconnects. Five categories, six product paths.

PRODUCT SCOPE

Four categories. Six product families.

Choose the category and closest product family, then align material, dimensions, finish, assembly and volume.

01

Cu-Al Composite Busbars & Transition Parts

Single-/double-sided clad sheets and bars, selective copper layouts, bent/punched busbars, shaped insulated conductors and transition parts. Confirm metal grades, layers and dimensions by drawing.

Cu-Al Composite Busbars & Transition Parts
01CU-AL · CORE PRODUCT LINE

Cu-Al Composite Busbars & Transition Parts

Cu-Al composite busbars, single-/double-sided clad sheets and bars, formed insulated conductors and transition parts. Review copper layout, contacts, processing, temperature rise and environment together; equal cross-section alone does not justify replacing copper.

  • Define metal grades, layer thickness and copper contact locations
  • Review bend radius, holes, cut edges and interface condition
  • Define validation for bolted, welded or transition connections

02

SMT Fastening Hardware

SMT nuts, standoffs and spacers

SMT Nuts & Standoffs
01SMT NUTS & STANDOFFS

SMT Nuts & Standoffs

Reflow-compatible PCB fasteners selected by thread or hole, outside diameter, height, material, finish and tape-and-reel format.

  • Pick-and-place surface and reel orientation
  • Reflow compatibility and land-pattern input
  • Torque, attachment and mechanical-load review

03

PCB Busbars & Crossovers

SMT busbars, conductor blocks and jumpers

SMT Busbars
01SMT BUSBARS

SMT Busbars

Board-level current reinforcement, heat spreading and power distribution, configurable by dimensions, material, finish, soldering process and tape-and-reel requirements.

  • Standard selection and equivalent-part assessment
  • Stamping, machining and finishing coordination
  • Pick surface, reel and pad design review
View specifications →
SMT Power Jumpers
02SMT POWER JUMPERS

SMT Power Jumpers

Board-level high-current crossovers for routing clearance and automated reflow assembly, assessed by span, standoff height, pad width, material and electrical duty.

  • 3D crossover for PCB routing conflicts
  • Pick-and-place and reflow integration
  • Span, standoff and cooling-space coordination

04

PCB Solder & Plug Terminals

PCB solder terminals, screw posts and power pins

PCB Solder Terminals
01PCB SOLDER TERMINALS

PCB Solder Terminals

High-current interfaces from a PCB to busbars, cables or equipment, covering through-hole, surface-mount, right-angle and custom soldered structures.

  • Terminal structure and PCB layout review
  • Material, plating and soldering-window checks
  • Torque, attachment and assembly-boundary review
View specifications →
05

Precision Stamped Parts & Clips

Grounding spring clips, shield clips and custom stamped parts

Precision Stamped & Custom Parts
01PRECISION STAMPED PARTS

Precision Stamped & Custom Parts

Custom conductive parts, terminals and contact structures coordinated from material and tolerance through stamping, forming, finish, prototypes and volume production.

  • Drawing DFM and tolerance-risk review
  • Material utilization and production optimization
  • Tooling, fixtures and inspection definition
