How to Operate PCBA Excel Price Sheets Without Shipping Frontend Changes

Key takeaways
- Operate PCBA quoting from admin Excel sheets: area/point tiers, lead-time adders, and effective dates
- No frontend release per change
- Reconcile 5–10 historical orders
- Prices stay estimates
How should PCBA Excel price sheets be operated? Keep ㎡ tiers, point bands, lead-time adders, and minima in admin sheets. Import to change rules—no frontend release. Each sheet needs an effective date; reloaded quotes lock the old band or warn that the sheet changed. Online prices are estimates pending engineering review. DAJIQUN follows factory pricing logic; sheet scope follows the signed SOW.
What the sheet must edit
Stackup ㎡ tiers, SMT point bands, hard-package adders, stencil/fixture fees, lead-time rates, currency and tax. Forbidden combos should be configurable. Import errors must name the row.
Effective dates and reloads
Do not silently reprice saved quotes. Lock the original band or ask for reconfirm. Reconcile 5–10 historical orders before going public.
