Quality

Quality & production: how every tag is made and checked

Tags are produced with an ISO 9001-certified production partner in Jiangsu; Antenza handles specification, sample testing, quality control and export. Here is the full process and what is checked at each step.

Six steps from design to shipment

The two highlighted steps run on every order: 100% inline electrical testing and batch RF characterisation.

  1. 01 Design & specification
  2. 02 Chip bonding
  3. 03 Converting
  4. 04 100% inline electrical test
  5. 05 Batch RF characterisation
  6. 06 Packing & labelling
  1. 01

    Design & specification

    Antenna footprint, chip and material stack are fixed from your surface, read distance and reader.

    Checked: spec sheet, bill of materials, encoding spec

    Antenza

  2. 02

    Chip bonding

    The UHF or HF chip is flip-chip bonded to the antenna to make the inlay.

    Checked: bonding set-up and first-article approval

  3. 03

    Converting

    Inlays are converted into dry inlays, wet inlays, paper labels or on-metal labels, and printed if required.

    Checked: dimensions, pitch, roll direction, print

    Production partner

  4. 04

    100% inline electrical test

    Every inlay is tested inline; failures are marked or removed as agreed in your order.

    Checked: every inlay

  5. 05

    Batch RF characterisation

    RF performance is measured on samples from each batch and compared with the approved sample.

    Checked: samples from every batch

  6. 06

    Packing & labelling

    Packed to the agreed core size, quantity per roll, carton labels and documents, then shipped.

    Checked: counts, labels, packing list

Documents you can request

Documents are supplied per order. Before you order, we confirm in writing which of them are available for your construction.

  • Product specification sheet

    Antenna size, chip, material stack, format and packing.

  • Chip vendor datasheet

    Sensitivity, memory and protocol from the official vendor document.

  • Batch test summary

    Summary of the inline electrical test and RF sample results for your batch.

  • ISO 9001 certificate of the production partner

    The partner’s quality-management certificate; an NDA may be required.

  • RoHS / REACH declarations

    For the exact materials in your order: chip, antenna, face stock, adhesive.

  • Packing list & labelling spec

    Quantity per roll, roll direction, carton labels and shipping documents.

Samples and the sampling plan

Samples before bulk is where quality control starts.

  1. 1

    Engineering samples

    Samples of the shortlisted designs, to compare on your items, readers and printers.

  2. 2

    Approved sample

    Once a design is chosen, the spec sheet and an approved (golden) sample are signed off as the reference for production.

  3. 3

    First-batch check

    The first production batch is checked against the approved sample before regular supply starts.

  4. 4

    Batch sampling

    Samples from every batch are RF-tested. Acceptance sampling to AQL levels (for example ISO 2859-1) can be agreed in the order. How to test tags before a bulk order

Frequently asked questions

If a tag does not read in the field, is it defective?
Every inlay is 100% electrically tested inline, and failures are removed or clearly marked as agreed in your order. A no-read in the field is more often caused by the tagged material, orientation or reader settings; send us the details and an engineer will help you find the cause.

Can I see test data?
Yes: ask for the batch test summary for your order. Before you order, we confirm what data can be supplied.

Can we audit production?
For volume projects, ask us about an audit or a video walkthrough of the production process. It is arranged case by case, usually under an NDA.

How are RFID tags made?
The process is summarised above. For the detail of each step, read how RFID tags are made.
