FAQ
What makes your copper conductive terminals different from competitors?
Our competitive edge comes from vertical integration – we control every production stage from raw material procurement to final packaging. This enables tighter quality control, faster turnaround times, and cost savings that we pass to customers. All components undergo 100% electrical continuity testing before shipment.
Can you produce conductive terminals with specific plating requirements?
Absolutely. We offer multiple plating options including tin, nickel, silver, and gold plating with thicknesses from 1-20μm. Our plating lines can handle both barrel and rack plating processes to accommodate different component geometries.
What is your minimum order quantity for custom conductive terminals?
While standard products have no MOQ, custom designs typically require a minimum of 500-1,000 pieces depending on complexity. We offer prototyping services starting at $200 to validate designs before full production.
How do you ensure dimensional consistency across large production runs?
We implement several quality control measures:
1) Automated CNC programs with tool wear compensation
2) In-process checks every 200-500 pieces
3) Statistical process control (SPC) monitoring
4) Final inspection using CMM and vision systems
5) Batch sampling for destructive testing
What documentation do you provide with shipments?
Every order includes:
– Material certificates (3.1 or 2.2)
– Dimensional inspection reports
– Plating thickness certificates
– Salt spray test reports (when applicable)
– Packing list with batch numbers
– Quality assurance declaration
