No. HXLFAB publishes an envelope of up to 850 × 520 mm panel size, 0.15–7.0 mm finished thickness, and 1–30 layers, but the simultaneous combination is not pre-approved. Material, copper, hole aspect, tolerances, registration, panel utilization, and equipment routing determine practical feasibility.
Submit the full constraint set
State finished board dimensions, whether the 850 × 520 mm value is relevant to a board or customer panel, finished thickness and tolerance, layer count, copper, smallest finished hole, material, and critical registration requirements.
Near-boundary reviews
Designs near one or more published limits may require different panelization, tooling, test, material, or tolerance assumptions. The quotation should record the confirmed construction rather than relying on a generic capability table.
Next useful step
Final capability, commercial terms, and project records are confirmed against the actual RFQ and written project documents.
