Engineering Solutions
Conditions first. Materials second.
Turn cost, thermal, joint-reliability and manufacturability questions into project inputs that can be validated, quoted and delivered.
Thermal & Joint Reliability
Address temperature rise and long-term risk through current capacity, contact resistance, fastening, plating and duty cycle.
Temperature riseInterface reliabilityFailure analysis
Manufacturability & Sourcing
Translate design intent into material, temper, tolerance, process, inspection and delivery requirements.
Drawing reviewProcess assessmentSupplier alignment
PROCESS
From drawing to volume in four steps.
- 01Describe project
Product, quantity, current and thermal requirements
- 02Add project files
Share 2D, 3D, PDF or photos when available
- 03Engineer review
Material, structure, process and manufacturability
- 04Quote & manufacture
Specification, prototype, inspection and delivery alignment
ENGINEERING METHOD
Validate the current path and every condition for production.
CUNECTRA reviews current, temperature rise, installation, materials, interfaces and manufacturing constraints, placing board-level components, terminals, custom conductors and Cu-Al composites in their real operating context.
PROJECT FAQ
Direct answers to common project questions.
Which copper interconnect products are covered?+
The core scope includes copper-aluminum composite conductors, rigid and flexible busbars, power terminals, and drawing-based custom copper parts.
Can a project start without complete CAD?+
Yes. A 2D drawing, PDF, product photo, or a brief covering current, temperature rise, space and quantity is enough for an initial review.
How is a Cu-Al composite option evaluated?+
Current capacity, temperature rise, interface design, corrosion environment, processing, assembly, long-term reliability and total cost must be reviewed together.
Are both prototypes and volume projects supported?+
Requirements can be defined separately for proof of concept, prototype, pilot validation and volume delivery, including material, process, inspection and quotation terms.
Can international projects be discussed?+
The site provides Chinese and English content and supports bilingual discussion of drawings, standards, delivery regions and project requirements.
