RoHS Compliant PCB Assembly — Lead-Free, EU Ready
All Kingdta PCB assemblies comply with EU RoHS Directive 2011/65/EU. We use exclusively lead-free solder alloys, RoHS-compliant components, and can provide full material declarations for EU and UK market entry.
What Is RoHS?
RoHS stands for Restriction of Hazardous Substances. The EU RoHS Directive (2011/65/EU, amended by 2015/863/EU) restricts the use of ten hazardous substances in electrical and electronic equipment (EEE) placed on the EU market. The restricted substances are:
RoHS compliance is mandatory for any electronic product sold in the EU or UK. Non-compliant products cannot legally be placed on these markets and may be seized at customs. Many other jurisdictions (China, South Korea, Japan, California) have adopted equivalent regulations.
What This Means for Your Project
EU & UK Market Access
Products assembled with RoHS-compliant materials and processes can carry the CE mark and be legally sold throughout the EU, UK, and most other regulated markets without restriction.
Material Declarations on Request
We can provide RoHS compliance declarations for your PCBA, including component-level material data from our authorised distributor supply chain. Supports your EU Declaration of Conformity.
Lead-Free Process Throughout
We use SAC305 (Sn96.5/Ag3.0/Cu0.5) lead-free solder paste and wire as standard. Our reflow ovens are profiled for lead-free alloys. No lead-containing materials enter our production line.
Authorised Distributor Sourcing
Components are sourced from authorised distributors (Digi-Key, Mouser, Arrow, Future Electronics) who provide manufacturer-certified RoHS compliance data for every part.
Reduced Environmental & Health Risk
Lead-free assembly protects workers in your supply chain and end-users. It also reduces liability exposure in jurisdictions with strict product liability laws for hazardous substance violations.
Leaded Process Available for Exemptions
Certain applications (aerospace, military, some medical) qualify for RoHS exemptions and require leaded solder for reliability reasons. We can accommodate leaded assembly upon request with full documentation.
How Kingdta Implements This Standard
RoHS-Compliant Component Sourcing
All components are sourced from authorised distributors with manufacturer-issued RoHS compliance certificates. Customer-supplied components (consignment) must include RoHS documentation.
Lead-Free Solder Paste & Process
We use SAC305 lead-free solder paste exclusively on our standard production lines. Paste is stored and used per manufacturer specifications. Reflow profiles are validated for SAC305 alloy.
Segregated Storage & Handling
Lead-free and leaded materials are physically segregated in our facility. Separate storage areas, stencils, and equipment prevent cross-contamination between lead-free and leaded processes.
Material Records Retention
Component RoHS certificates and material declarations are retained for a minimum of 10 years, supporting your product compliance documentation for EU market authorities.
RoHS Compliance Declaration
Upon request, we issue a Kingdta RoHS Compliance Declaration for your PCBA order, confirming that all materials and processes comply with EU RoHS 2011/65/EU as amended.
