Overview

EN 61249-5-4:1996 (adopted as SIST EN 61249-5-4:1997) is a sectional specification in the EN 61249 family covering materials for interconnection structures. This part specifically addresses conductive inks and sets out the requirements for their qualification and for inks intended to be used as substitutes for metallic contact finishes. The standard is aligned with IEC 1249-5-4:1996 and falls under the printed circuits and boards classification (ICS 31.180).

Key Topics

The standard focuses on the qualification and performance expectations of conductive inks used in interconnection and contact applications. Key technical topics typically covered include:

• Qualification requirements and procedures for conductive inks used in electronic interconnections.
• Performance characteristics relevant to contact applications, such as electrical conductivity and contact resistance (general concept; specific thresholds are in the standard text).
• Compatibility and adhesion to common substrates used in printed circuit boards and flexible interconnects.
• Durability and environmental resistance, including performance under expected operational stresses and ageing.
• Formulation and processing considerations, including suitability for application and curing methods (without prescribing specific chemistries).
• Use as substitutes for metallic finishes on contacts, requiring demonstration of equivalent performance for reliability and service life.

Applications

EN 61249-5-4 is useful wherever conductive inks are selected, qualified or specified for electrical interconnection and contact applications:

• PCB and flexible circuit manufacturers evaluating conductive inks for circuit traces, repair, or selective plating substitutes.
• Ink formulators and material suppliers developing conductive pastes, inks and coatings for contact surfaces.
• Electronic OEMs and contract manufacturers that need to approve conductive-ink-based contact finishes as alternatives to plated metallic contacts.
• Quality, reliability and test laboratories responsible for verifying compliance with qualification criteria before production use.
• Procurement and standards teams writing material specifications for supplier qualification.

Related Standards

• IEC 1249-5-4:1996 - original international reference equivalent to EN 61249-5-4.
• Other parts of the EN/IEC 61249 series covering foils, films and materials for interconnection structures.
• Broader printed circuit board standards (ICS 31.180) governing substrate and assembly requirements.

EN 61249-5-4 is a practical reference for anyone specifying or qualifying conductive inks as reliable conductive layers or replacements for metal contact finishes in electronic assemblies.
