RoHS

Restriction of Hazardous Substances (RoHS) limits lead, mercury, cadmium, hexavalent chromium, and selected brominated flame retardants (PBB, PBDE) plus four phthalates (DEHP, BBP, DBP, DIBP under RoHS 3) in electrical and electronic equipment placed on EU market — with concentration limits in homogenous materials (typically 0.1% by weight except cadmium 0.01%). SiCore dock controllers, receivers, cables, and accessories shipped to EU, and many global customers mirroring RoHS in procurement specs, require RoHS-compliant bill of materials with supplier evidence chains.

Industrial wireless charging products contain high-power magnetics, ceramic capacitors, heat sinks, connectors, and PCB assemblies — each homogenous material must comply or qualify under applicable RoHS exemptions with documented sunset tracking. RoHS is material compliance, not performance or safety — but enterprise AGV customers increasingly gate vendor approval on RoHS and REACH documentation alongside UL/CE certificates.

01Compliance process for SiCore BOM

• Supplier declarations (SDS/CoC): collect full material disclosures from magnet wire, ferrite, solder, and connector vendors.
• Homogenous material definition: distinguish plating vs base metal, potting compounds, and adhesive layers — each tested or declared.
• Exemption tracking: e.g., cadmium in specific uses, lead in high-melting solder — document expiry dates under Annex III/IV reviews.
• XRF screening and lab analysis: spot-check incoming lots for restricted substances when supplier risk elevated.
• Product labeling: RoHS compliance statement on datasheet and DoC — distinguish EU RoHS from China RoHS and California RoHS where requested.

02Industrial-specific considerations

High-reliability industrial solder joints historically used leaded solder in prototypes — production EU SKUs must use RoHS-compatible alloys with reflow profile validation on heavy copper WPT boards to avoid voiding in high-current vias. Ferrite and copper magnetics are generally RoHS-relevant for surface coatings and adhesives rather than core composition — verify epoxy and coating on coil assemblies.

Spare parts and field replacement modules must match original RoHS status — service BOM flagged separately if legacy exempt parts remain in supported installed base during exemption transition. Customer requests for RoHS-6 vs RoHS-10 (including phthalates) specify scope in procurement contracts — SiCore standard declaration covers RoHS 3 ten substances unless dated otherwise.

03Documentation and audits

Maintain RoHS compliance folder per SKU linked to UL/CE file for customer audit efficiency — IMDS or IPC-1752 material declaration format when automotive logistics customers require. RoHS non-compliance blocks EU shipment — logistics systems should flag SKU destination and required conformity packet. This guidance supports engineering and supply chain direction; legal interpretation of exemption applicability for specific part numbers requires compliance specialist review when exemptions expire or designs change.
