2026-05-29
Your PCBA order is delayed. Why?
Understanding lead time drivers helps you plan better and avoid surprises.
Here are 5 key factors.
The 5 Factors
Factor Impact on Lead Time What You Can Do
Component availability +1–8 weeks Use common parts; send BOM early for check
PCB layer count +2–5 days Standardize on 2–4 layers if possible
Quantity +1–4 weeks Order prototypes first, then scale
Special requirements +3–7 days Press-fit, controlled impedance, special surface finish
Factory workload +1–3 weeks Order early; avoid Q4 rush
