CE certification is a mandatory conformity mark for PCBA (Printed Circuit Board Assembly) products intending to enter the European Union (EU) market and the European Economic Area (EEA), serving as a guarantee of product safety, health, and environmental protection compliance. For PCBA, the certification process is not a single test but a comprehensive assessment based on the product’s intended use, involving multiple EU directives and corresponding testing standards to ensure that the product meets the minimum safety and performance requirements of the EU market.

The core EU directives applicable to PCBA include the Low Voltage Directive (LVD, 2014/35/EU), the Electromagnetic Compatibility Directive (EMC, 2014/30/EU), the Restriction of Hazardous Substances Directive (RoHS, 2011/65/EU), and the Radio Equipment Directive (RED, 2014/53/EU) for PCBA integrated with wireless functions such as Wi-Fi or Bluetooth. The LVD applies to PCBA operating within the voltage range of 50V~1000V AC or 75V~1500V DC, ensuring electrical safety through tests referenced to standards like EN 62368-1 and EN 61010-1. The EMC directive requires PCBA to pass radiation emission (EN 55032) and immunity (EN 61000-4 series) tests to avoid electromagnetic interference with other devices and resist external interference.

The RoHS directive restricts the use of six hazardous substances, including lead and mercury, in PCBA, with specific exemption items requiring separate evaluation. The certification process involves product classification, testing (either self-assessment for low-risk products or third-party testing by EU Notified Bodies for high-risk products), technical documentation preparation (including circuit diagrams, BOM lists, test reports, and risk assessment reports), signing the Declaration of Conformity (DoC), and affixing the CE mark. It is important to note that if PCBA is sold as a component, the final product manufacturer is usually responsible for CE certification; if sold as an independent product, it must be certified independently. Additionally, design or material changes require re-testing to maintain compliance, ensuring long-term market access in the EU.
