Indicative industry ranges for design and RFQ preparation. Confirm the exact figures and applicable standard with the manufacturer before specifying.
A practical evidence checklist for RFQ preparation and supplier evaluation.
CNFX does not score or rank suppliers. Buyers must verify all claims and documents with the legal manufacturer before ordering.
4 companies list this product among what they make. Company figures are quoted from each company's own website; every card states where the relationship came from.
Manufacturer listings support early research and capability understanding. They are not certification, ranking, or transaction guarantees.
Ask for use case, specification boundaries, supplier type, and RFQ preparation information for this product.
According to the directory, board sizes typically range from 300 to 500 mm, and layer counts from 4 to 32. However, custom sizes up to 600 mm are available. Always confirm the exact dimensions and layer count with the manufacturer for your specific application.
Common standards include IPC-6012 Class 3 for performance, IPC-2221 for design, and IPC-2141 for impedance control. Additionally, mechanical specifications must match the specific ATE platform. These standards serve as procurement references; verify compliance with the supplier.
The directory lists a maximum test frequency range of 1 to 10 GHz, depending on material and design. For high-speed signals, impedance tolerance is ±5% per IPC-2141. Confirm the actual frequency capability with the manufacturer for your specific design.
Available surface finishes include ENIG, ENEPIG, and OSP, per IPC-4552. The choice depends on flatness and solderability requirements. Verify the finish and its compliance with your assembly process with the supplier.
