Boards, parts and the BOM behind them.
Schematic and PCB work, BOM cleanup, sourcing with approved alternatives, and assembled boards and harnesses.
Who this is for
A development-board or breadboard prototype that needs its own board, a PCB that needs revising, or a BOM that has to be bought and built, including older and hard-to-find chips.
Typical starting points
- A breadboard or development-board prototype
- An existing schematic or PCB to review or revise
- A BOM with parts that are hard to find, slow to arrive or no longer made
What Anvol does
- Schematic and PCB review
- Schematic, PCB layout and power design
- BOM cleanup
- Component sourcing, including older and hard-to-find chips
- Alternative parts identified and checked; none used without your approval
- Component lifecycle check
- PCBA and wiring harnesses
- Production files
- Parts purchasing for small batches
Deliverables
- Schematic, PCB files and Gerbers
- A full BOM with a source for each part, costed from real parts and supplier quotes and checked by an engineer
- Approved alternative parts
- Assembled boards and harnesses
BOM risk table (example)
How we report part risk in a BOM review. The rows below are an illustration, not parts from a client project.
| Original component | Availability | Approved alternative | Electrical compatibility | Mechanical compatibility | Client approval |
|---|---|---|---|---|---|
| Wi-Fi / BLE module | Long lead time | Module from a second maker | Same supply and I/O; firmware needs a driver check | Same footprint | Pending |
| Electrolytic capacitor | No longer made | Same value and rating, another series | Matches | Taller; enclosure clearance checked | Approved |
| 3.3 V regulator | In stock | Not needed | n/a | n/a | n/a |
Typical inputs
- Schematic or PCB files, if you have them
- Photos of what works
- A BOM, if there is one
- Target quantity
Timeline and cost drivers
- Timeline
- Set mostly by part availability. The BOM review shows which parts are slow to get, and the dates go in the written scope.
- Cost depends on
- Board complexity, number of revisions and part availability. Each board-assembly run pays a fixed machine setup charge, so the quantity matters too.
- Small batches
- In batches of 5 to 20, parts are about 40% of unit cost and PCB and assembly about 40%. Costs →
What is excluded
- Certification testing (FCC/CE). It is done by a test lab and quoted separately when a product needs it.
- Using an alternative part without your approval.
- Shipping and import duties. Usually arranged by you once units leave the factory.
- Anything outside the written scope. Major scope changes are re-quoted, with a new timeline, before work continues.

Questions
Yes. Component sourcing is part of what we do, including older and hard-to-find chips. You get the full BOM with the quote.
No. Part substitutions need your approval before the part is used. Change control →
