BOM Normalization
Part numbers, descriptions, manufacturers, quantities and reference designators cleaned and verified.
Electronic component sourcing converts a raw BOM into a controlled supply plan by validating part numbers, availability, lifecycle status, approved suppliers, traceability and acceptable alternates before PCBA production begins.
More than purchasing
Every component choice affects cost, lead time, assembly yield and product continuity. We normalize your BOM, verify manufacturer part numbers, review stock and lifecycle exposure, and create a controlled sourcing plan aligned with your technical and commercial requirements.
Core sourcing capabilities
Part numbers, descriptions, manufacturers, quantities and reference designators cleaned and verified.
Current stock, allocation exposure, minimum order quantities and lead-time risks reviewed before commitment.
NRND, end-of-life and obsolete parts identified with practical mitigation options for continuity.
Pricing, packaging, order quantities and approved alternatives evaluated without compromising requirements.
Authorized distribution is preferred, with vetted channels and risk controls used when necessary.
Packaging, labels, date codes, moisture status and component quality control before production release.
Controlled workflow
Material assurance
Risk and optimization
Important: substitutions are proposed with supporting information and used only after customer approval.
Frequently asked questions
Include manufacturer part number, manufacturer name, description, quantity, reference designators and any approved alternatives or sourcing restrictions.
No. Proposed alternatives are documented and require customer approval before purchase or production use.
Yes. We can support turnkey, partial-turnkey and consigned-material models, with incoming checks and inventory control defined for the project.
Send your BOM and target quantities for a practical review of availability, lifecycle risk, pricing and approved sourcing options.
Submit Your BOM for ReviewPurchasing FAQ
Practical answers about files, schedule, engineering support, production coordination and confidentiality.
For Component Sourcing Services, send the BOM with manufacturer part numbers, approved alternates, target quantities, required date, lifecycle or compliance requirements, and identify any customer-supplied or restricted components.
Lead time depends on design maturity, complexity, quantity, material or component availability, testing scope, and how quickly engineering questions are resolved. We confirm the schedule after reviewing your files; urgent prototype or quick-turn options can be discussed where the required process and materials permit.
Gerber and ODB++ are the preferred neutral production formats. If your source data is in a native EDA tool, tell us the software and version; we will confirm compatibility or ask for a controlled Gerber/ODB++ export, drill data, drawings and other release files.
Yes. We can work from an existing design, production package or previous revision. We first check completeness, revision control and the requested scope, then identify any missing data, manufacturability risks or changes that need your approval before work begins.
Yes, SI/PI analysis can be coordinated when manufacturing or assembly risk depends on controlled impedance, return paths or power integrity. It is a separate engineering scope and requires suitable design data, stackup information, models and acceptance criteria.
Yes. Excel Circuit can coordinate fabrication, component sourcing, PCB assembly, inspection, testing and related box-build work as one project. The quotation states which stages are included, which materials are consigned, and the approvals needed before production.
Project files are limited to personnel and qualified partners who need them for quotation and delivery. Excel Circuit uses reasonable technical and organizational safeguards, does not publish customer designs without permission, and can work under a mutually agreed NDA. Your signed NDA or project agreement controls where it provides specific protections.
Final scope, price and lead time are confirmed after engineering review of your current files and requirements.
