1. Overcoming Complex Yield Barriers: Many fabricators struggle with yield loss on high-layer count stackup designs. DuxPCB utilizes advanced registration systems and vacuum lamination to ensure your complex multi-layer Goldfinger boards are delivered right the first time, every time.
2. Eliminating Field Failures: In Aerospace and Medical sectors, a single contact failure is catastrophic. We apply IPC Class 3 reliability protocols and rigorous AOI testing to ensure your Advanced PCBA solutions function flawlessly in life-critical environments.
3. Proactive Technical Consulting: Don't pay for preventable redesigns. Our engineers provide expert DFM consulting for Fine pitch BGA and controlled impedance layouts, identifying potential manufacturing bottlenecks before they impact your budget.
4. Scaling Without Delays: Moving from a difficult prototype to volume production often causes supply chain friction. DuxPCB bridges this gap with precision manufacturing workflows that scale seamlessly, maintaining 5-10 day build times regardless of complexity.
What is the standard beveling angle for Goldfinger PCBs?
We typically provide 30-degree or 45-degree chamfering to ensure smooth insertion into the backplane connector. We maintain a minimum of 0.15mm space between the finger and the bevel to prevent damage.
Do you support both Hard Gold and ENIG on the same board?
Yes, we can perform selective plating, such as ENIG for component soldering and hard gold for the edge connectors, providing the best of both worlds for conductivity and durability.
