EUROLAB, with its state-of-the-art accredited laboratories and expert team, provides precise and fast testing services within the scope of IEC EN 61249-4-18 testing. IEC EN 61249-4-18 gives the requirements for prepreg properties intended for use as bonding sheets in conjunction with laminates according to IEC EN 62326-4-61249 when producing multilayer sheets according to IEC EN 2-39.
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 defined flammability (vertical combustion test). The degree of flammability on the fully cured prepreg is achieved through the use of brominated flame retardants, which are an integral part of the polymeric structure. The glass transition temperature is defined as a minimum of 170 °C after the prepreg has been cured according to the supplier's instructions.
High performance epoxy resins with a glass transition temperature after curing at a minimum of 170°C according to the manufacturer's instructions. The degree of flammability is achieved through the use of brominated flame retardants that react with the polymer. Inorganic fillers can be used. Contrast agents can be added to improve processing, such as automatic optical inspection (AOI).
In deciding the presence of broken filaments, their size and frequency of occurrence are important for assessing acceptability, but the flow characteristic of the prepreg must also be considered. Acceptance conditions for broken filaments will be as agreed between the user and the supplier.
The nominal thickness and tolerance of the prepreg cured using the user's lamination cycle shall be as agreed between the user and the supplier. The test method will be as agreed between the user and the supplier.
Prepregs provided under this standard will be qualified. A proficiency test should be carried out to demonstrate the manufacturer's ability to meet the requirements of this standard. The proficiency testing must be performed in a laboratory that complies with IEC laboratory requirements. The manufacturer will keep on file data supporting that materials meet this standard and will be available for review upon request.
