IEC EN 61249-4-17 Materials for Printed Sheets - Part 4-17: Sectional Specification Set for Uncoated Prepreg Materials

EUROLAB, with its state-of-the-art accredited laboratories and expert team, provides precise and fast testing services within the scope of IEC EN 61249-4-17 testing. IEC EN 61249-4-17 gives requirements for prepreg properties intended for use as bonding sheets in conjunction with laminates according to IEC EN 62326-4-61249 when producing multi-layer sheets according to IEC EN 2-38. Multilayer boards made of these materials are suitable for lead-free assembly operations.

This material can also be used to bond other types of laminate. According to this standard, Prepreg has a defined flammability (vertical combustion test). The degree of flammability on the fully cured prepreg is achieved through the use of non-halogenated flame retardants as an integral part of the polymeric structure. The glass transition temperature is defined as a minimum of 120°C after the prepreg has been cured according to the supplier's instructions.

When assessing the presence of broken filaments, not only their size and frequency of occurrence, but also the flow characteristic of the prepreg should be considered to assess acceptability. Acceptance conditions for broken filaments will be as agreed between the user and the supplier.

The nominal thickness and tolerance of the cured prepreg shall be as agreed between the user and the supplier. The prepreg tested should be glued together and fully cured according to the manufacturer's recommendations. The test method will be as agreed between the user and the supplier.
