BOM scrub
Line-by-line check of MPN, manufacturer and reference-designator consistency, package, MSL grade and lifecycle status.
COMPONENT SOURCING · BOM SCRUB TO LAST-TIME-BUY
Your BOM, sourced through authorised channels.
Every line is flagged Active, NRND or EOL before anything is ordered, and purchasing goes through authorised and franchised distribution with incoming inspection aligned to AS5553 / AS6081 counterfeit-avoidance practice. Component lead time can add 12–26 weeks on long-lead semiconductors, and no part is ever substituted without your written approval.
THE PURCHASING SEQUENCE
Six steps from your BOM to a kitted line
Nothing is bought until the risk report has been read and the alternates have been approved in writing. That order is deliberate: it is cheaper to argue about a part number than about a reworked batch.
Lifecycle & long-lead report
Active, NRND and EOL flagged per line, with single-source rows and long-lead rows called out before the stencil is cut.
Customer approval on alternates
Datasheet-level parameter comparison for every proposed alternate or second source, submitted for your written approval. No automatic substitution.
Purchase via authorised distributors
Authorised and franchised channels first. Open-market or broker purchase needs your written consent and a tightened incoming inspection regime.
Incoming inspection
Quantity, marking, packaging and documentation checked against AS5553 / AS6081 counterfeit-avoidance practice, with the record filed against your lot.
Bake / dry-pack and kitting to line
Moisture-sensitive parts baked where floor exposure has been exceeded, then kitted to the line in reels, trays or tubes.
THE FULL SERVICE LIST
Seventeen procurement services, item by item
This is the whole scope, including the two lines most suppliers leave out: what happens when a part can only be found on the open market, and what a consigned-material shortfall means for you.
| Service | What it covers | Basis |

| Lead-time basis | The bottleneck is the component, so every date is an assembly lead time ex-components | Industry practice |
WHERE THE PARTS COME FROM
Authorised channels first, and in writing
The grey market is not a moral question, it is a documentation question: a part bought from an unauthorised broker arrives without a traceable chain, and no incoming inspection can reconstruct one. So the default is authorised and franchised distribution, and any exception is your decision, not ours.
Default channelAuthorised and franchised distributors
Broker marketOnly with your written consent
Incoming inspection basisAS5553 / AS6081 practice
Open-market visual standardIDEA-STD-1010 class inspection
Why it mattersERAI logged 1,055 suspect counterfeit and nonconforming parts in 2024, with counterfeit reports at a nine-year high
LIFECYCLE AND LEAD TIME, STATED PLAINLY
What happens when a part stops being made
Obsolescence is the normal condition of this industry, not an exception. Roughly 750,000 electronic components went obsolete in 2022 and more than 470,000 reached end of life in 2023, so the useful question is not whether your BOM will lose a part but what the plan is when it does.
ActiveNormal purchase against your schedule
NRNDNot recommended for new designs; last-time-buy requirement assessed at intake
EOLTriggers a last-time-buy plan and second-source qualification
Notice mechanism, industry practiceJ-STD-048 withdrawal notice and J-STD-046 change notice, typically 12 months for the last order plus 6 months for final delivery
Read that asIndustry practice, not a commitment we can make on a manufacturer's behalf
Long-lead semiconductorsComponent lead time can add 12–26 weeks on long-lead semiconductors
Consequence for schedulingEvery date we quote is an assembly lead time ex-components
WHAT WE DO WITH YOUR BOM
Six sourcing capabilities
RISK REPORT
BOM scrubbing and risk report
Five risk classes flagged line by line: lifecycle status, single source, long lead time, compliance and counterfeit exposure, working to AS5553 / AS6081 counterfeit-avoidance practice.
ALTERNATES
Alternate parts and second sources
Datasheet-level parameter comparison, approved-vendor-list parts preferred, and your written approval before anything is bought. Automatic substitution is not available, by rule.
MOISTURE
MSL control and baking
Exposure time on the floor tracked against the MSL grade of each moisture-sensitive part, with a bake before use when the limit is exceeded.
DOCUMENTS
Compliance documentation
RoHS 3 declarations and test reports, REACH SVHC statements and an annual CMRT. These are declarations and reports, not certificates, and they are supplied as such.
END OF LIFE
Last-time-buy planning
A last-time-buy at the end of a product's life, sized against your remaining production forecast, with a second-source route qualified alongside it.
CONSIGNMENT
Customer-supplied material
Receipt, counting and reconciliation of consigned parts, with the industry-standard 5–10% attrition allowance on SMT passives agreed up front rather than argued about at the end.
THE STEP THAT RUINS A BATCH
Moisture is the one incoming defect that spreads
A counterfeit part fails its own joint. A moisture-soaked part fails the whole assembly at reflow, when trapped water flashes to steam inside the package and cracks the body from the inside. That is why MSL control sits here, next to purchasing, and not in a footnote.

Shipping and storageMoisture-barrier bag, desiccant and humidity indicator card
Failure mode if ignoredPopcorning and delamination inside the package
PACKAGING AND DOCUMENTS
What arrives with the parts
MOISTURE
Moisture-barrier packaging
Moisture-barrier bag with desiccant and a humidity indicator card, so the condition of the parts on arrival is visible before the bag is opened rather than assumed.
ESD
ESD packaging
Static-dissipative bags and ESD tote boxes for storage and line-side movement, matching the handling requirement of the parts inside them.
FORMAT
Reels, trays and tubes
Parts kitted in the format the placement machine consumes, with surplus returned in the same format so your own stock records stay reconcilable.
PAPERWORK
Compliance document pack
RoHS 3 declaration and test reports, REACH SVHC statement, annual CMRT and lot-level traceability records, issued per shipment on request.

SECTOR RISK PROFILES
What procurement risk looks like in six sectors
Industrial automation
Fifteen-year PLC lifetimes
Two to three engineering changes inside one PLC-grade product life, and obsolete parts that force a board revision rather than a part swap.
Medical devicesChange control down to the lot
Traceability to component lot, validation documents for each change and a recall exposure measured in millions of dollars.
Automotive & EVPPAP and 8D discipline
PPAP documentation per part change and 8D timelines that start at 24-hour containment for a field or zero-kilometre failure.
Consumer & IoTWeek-scale BOM churn
Cost pressure and weekly iteration, with radio-module certification needing antenna and shielding decisions settled early.
Energy & powerFifteen to twenty-five years in the field
Long service life on heavy copper and power devices, where a supply interruption has to be answered with a lifetime buy.
Telecom & data centreRe-qualification on any swap
112 Gbps PAM4 interfaces tolerate very little impedance change, so a part substitution means re-verifying signal integrity.
ANONYMISED CASE

ENERGY & GRID · NETHERLANDS · 2-LAYER POWER BOARD
A Dutch grid-equipment maker with a part going out of supply
A single component in a 2-layer power board reached end of life with no drop-in alternate available from any authorised channel. The board could not be redesigned quickly enough to keep the product shipping.
