Quality & Compliance
Our quality policy, the certifications we hold, and the material and sourcing declarations available for your compliance file.
Frequency control components are usually the smallest part on the board and the first to be blamed when a system drifts. Our quality system exists to make that conversation short: every part leaves with a test record, and every claim is investigated against that record.
1. Quality policy
We are committed to supplying quartz crystals and oscillators that meet the published specification on every shipment, to delivering on the date we confirm, and to maintaining a management system that is audited and improved continuously. Quality objectives are reviewed at management review, and every employee is authorised to stop a shipment that does not meet specification.
2. Certifications
| Standard | Scope | Certificate |
|---|---|---|
| ISO 9001:2015 | Design, manufacture and distribution of frequency control components | Available on request |
| ISO 14001:2015 | Environmental management across both production sites | Available on request |
| IATF 16949:2016 | Automotive supply, crystal and oscillator lines | Available on request |
| ISO 45001:2018 | Occupational health and safety | Available on request |
| AEC-Q200 | Automotive qualification of discrete components | Per part number |
Certificates are issued by an accredited certification body and are valid for three years, subject to annual surveillance audits. Current copies, showing the certificate number, issuing body and expiry date, are supplied with any quotation on request.
3. Test and qualification
Every production lot is tested to the parameters in the datasheet. Typical coverage:
- 100% test of frequency, equivalent series resistance, drive level dependence and insulation resistance.
- Stability verification across the full operating temperature range on each lot, not on a sample.
- Ageing: 30 days at 85 °C for standard parts, extended to 1,000 hours for automotive and OCXO products.
- Environmental qualification per AEC-Q200 where applicable: temperature cycling, damp heat, mechanical shock, vibration, solderability and resistance to soldering heat.
- RoHS and REACH screening on incoming materials, with supplier declarations held on file.
4. Traceability
Each reel, tube or tray label carries a lot code that resolves to the crystal blank batch, the package batch, the assembly line, the shift and the test data. Records are retained for ten years, which satisfies the traceability expectations of automotive, medical and aerospace customers.
5. RoHS, REACH and halogen
All catalogue parts comply with Directive 2011/65/EU (RoHS 3) and are free of the substances restricted under REACH Annex XVII above the 0.1% threshold. Declarations of conformity, full material declarations and REACH SVHC statements are available per part number. Halogen-free variants are available on request and are marked with the HF suffix.
6. Conflict minerals
We support the responsible sourcing of tin, tantalum, tungsten and gold. We require our suppliers to source from validated smelters under the Responsible Minerals Assurance Process, and we provide a CMRT (Conflict Minerals Reporting Template) on request. Where a smelter cannot be validated, we work with the supplier on an alternative source rather than continue the exposure.
7. Counterfeit avoidance
We buy only from original manufacturers and their franchised channels, and we do not trade in broker stock. Incoming goods are checked for labelling consistency, lot code format, packaging integrity and, where there is any doubt, X-ray fluorescence and decapsulation. Parts that cannot be traced to an original manufacturer are quarantined and returned.
8. ESD and moisture handling
Assembly areas are monitored for static control to ANSI/ESD S20.20. Surface-mount parts are packed to J-STD-033 in moisture-barrier bags with desiccant and a humidity indicator card, and are labelled with the moisture sensitivity level and the floor life. Reels that have been opened in our facility are resealed and re-labelled with the remaining floor life.
9. Product change notification
Where a change affects form, fit or function – a change of crystal blank supplier, package material, plating or test limit – we issue a Product Change Notification at least 90 days before the change takes effect, together with a qualification summary and a sample on request. Customers with an automotive or medical part approval can require re-qualification before accepting the change.
10. PPAP and audits
For automotive programmes we support PPAP at levels 1 to 5, including control plans, MSA studies, capability data and IMDS submissions. Customer and third-party audits can be arranged with four weeks’ notice; we will share the most recent certification body audit report under NDA in the meantime.
