Quality · Traceability

Traceability — from goods receipt to shipping.

Every batch, every test result and every material certificate stays uniquely traceable and audit-proof at tech-mo.

As an ISO 9001:2015 certified manufacturing partner we work with documented processes. This page shows our process chain, the typical document types and the applicable retention periods.

Process overview

Seven stations form our traceability chain. Every station produces data records that can later be uniquely assigned to a production batch.

  1. 01

    Goods receipt

    Delivery note, batch/lot number and manufacturer certificate are recorded. Visual and identity check, release into blocked or free warehouse.

  2. 02

    Material assignment

    Each production batch is uniquely linked to the materials used — including cables, contacts, PCBs and consumables.

  3. 03

    Manufacturing

    Work steps, machines, tools and operators are recorded per order. Crimp force monitoring and process parameters flow into the manufacturing record.

  4. 04

    Inspection

    Intermediate and final inspections, pull-off tests, high-voltage and continuity tests with logged measurements and results.

  5. 05

    Labelling

    Customer and batch labels, optionally serial number, DataMatrix or QR code — durable, legible and customer-specific.

  6. 06

    Shipping

    Delivery note and inspection record reference the production batch. On request with works certificate 2.1/2.2 or digital test report.

  7. 07

    Archiving

    Manufacturing and inspection records are archived in an audit-proof way and can be reproducibly provided on request.

Document types

Which records we keep by default — and extend on customer request.

Production order

Bill of materials, routing, lot size, customer and drawing revision.

Test protocols

Results from crimp, pull-off, continuity and high-voltage tests including measurements.

Material certificates

Works certificates 2.1/2.2, RoHS/REACH declarations and manufacturer batches.

First article inspection

FAI/PPAP-style report per customer specification for release of new parts and revisions.

Change and revision history

Drawing, process and BOM changes including approval status.

Calibration records

Calibration records of the test equipment used with validity date.

Retention periods

We archive in an audit-proof way and can reproducibly provide documents on request. Deviating project-specific periods are agreed individually.

  • Manufacturing & inspection records

    10 years

    Standard — extendable on customer request or per industry requirements (e.g. automotive, medical).

  • Material certificates

    10 years

    Retained alongside the associated production batch.

  • First article inspection reports

    Lifetime of the part

    Updated on every revision; previous versions remain referenceable.

  • Test equipment calibration

    At least 3 calibration cycles

    History to trace back past inspections.

  • Commercial documents

    10 years (German HGB/AO)

    Order confirmations, delivery notes, invoices.

  • Complaints & 8D reports

    10 years

    Including root cause analysis and effectiveness check of measures.

Information without guarantee. Statutory periods follow German commercial and tax law as well as, where applicable, industry-specific regulations.
