Why BOM quotes fail
Mixed-signal boards are sensitive to suffix, analog performance and support components. A BOM should flag converter lines, references and precision amplifiers before quote work starts.
BOM review flow
Step 1
Normalize manufacturer names and orderable part numbers
Step 2
Flag package-sensitive, obsolete and high-value lines
Step 3
Separate sample, pilot and production quantities
Step 4
Confirm alternates before supplier screening
Step 5
Return quote feedback with risk notes
How to clean part numbers
| BOM problem | Buyer fix |
|---|---|
| Short base numbers | Add suffix, package, grade and packing notes |
| Mixed manufacturer names | Keep preferred manufacturer and allowed alternates in separate columns |
| No quantity split | Mark sample, pilot and production demand separately |
| Old date-code rule | State realistic acceptance or explain the restriction |
What to send before quotation
- Full orderable part number and manufacturer preference
- Target quantity and delivery destination
- Package, suffix, temperature grade and date-code requirement
- Approved alternates or parts that must not be substituted
- BOM file, photos or previous supplier documents when available
