What is BS EN 61249-4-11 - Materials for printed boards about?
BS EN 61249-4-11 is an international standard that discusses materials for printed boards and other interconnecting structures.
BS EN 61249-4-11 gives requirements for properties of prepreg that are mainly intended to be used as bonding sheets in connection with laminates according to IEC 61249-2-7 when manufacturing multilayer boards according to IEC 62326-4. This material may be also used to bond other types of laminates.
Who is BS EN 61249-4-11 - Materials for printed boards for?
BS EN 61249-4-11 on materials for printed boards and other interconnecting structures is useful for:
- Manufacturers of printed circuit boards (PCBs)
- Manufacturers of electronic components and interconnecting structures
- Manufacturers and suppliers of laminate sheets
- Quality control and testing personnel
- Inspection authorities
Why should you use BS EN 61249-4-11 - Materials for printed boards?
Prepreg according to BS EN 61249-4-11 is of defined flammability (vertical burning test). The flammability rating on fully cured prepreg is achieved using non-halogenated fire retardants contained as an integral part of the polymeric structure. After lamination according to the supplier’s instructions, the glass transition temperature is defined to be 120 °C minimum.
BS EN 61249-4-11 covers the best industry guidance on sectional specification set for prepreg materials, unclad for printed boards. It exemplifies the requirements for materials and construction, as well as reference standards’ test methods to verify electrical properties along with non-electrical properties of the unclad laminate. It also provides you with reference test methods for the verification of properties such as flexural strength, flammability, and measling.
Compliance with requirements and tests provided by BS EN 61249-4-11 can thus demonstrate the reliability, quality, and performance of materials for printed boards and interconnecting structures.
