How Lead Times Are Calculated

2026-09-26  |  Views

Production days, not calendar days

Quoted lead times count working days from payment plus DFM approval. Layer count and board area set the base: 1-2 layer boards from 24 hours (express), 10-20 layer boards 5-10 days. Express tiers are explained on the Quick-Turn page.

Special processes (heavy copper, impedance coupons, IPC Class 3 inspection) add time shown in the quote. If engineering review pauses production, affected days are added back — never silently lost.
