What is BS EN 61249-2-42 - Brominated epoxide non-woven / woven E-glass reinforced laminate sheets about?
BS EN 61249-2-42 is the second part of a multi-series standard used for Materials for printed boards and other interconnecting structures.
BS EN 61249-2-42 gives requirements for properties of brominated epoxide non-woven reinforced core/woven E-glass reinforced surface laminate sheets of defined flammability (vertical burning test), copper-clad for lead-free assembly in thicknesses of 0,60 mm up to 1,70 mm. The flammability rating is achieved through the use of brominated fire retardants reacted as part of the epoxide polymeric structure. The glass transition temperature is defined to be 105 °C minimum.
Some property requirements may have several classes of performance. The class desired should be specified on the purchase order, otherwise the default class of material will be supplied.
Who is BS EN 61249-2-42 - Brominated epoxide non-woven / woven E-glass reinforced laminate sheets for?
BS EN 61249-2-42 on Materials for printed boards and other interconnecting structures is useful for:
- Manufacturer of electronic components
- Manufacturer of automotive parts
- Manufacturer of printed circuit boards
- Electronic engineers
Why should you use BS EN 61249-2-42 - Brominated epoxide non-woven / woven E-glass reinforced laminate sheets?
Printed circuit boards (PCBs) are useful for supporting mechanically and electrically connecting electronic components. This is connected by using conductive pathways, tracks, or signals.
BS EN 61249-2-42 specifies the materials to be used in constructing printed boards according to their operational requirement. This helps in determining the electrical properties of clad and unclad materials. The non-electrical properties of the copper-clad laminate are useful in avoiding the defects in these materials. With the help of BS EN 61249-2-42, you can determine the flammability and water absorption capacity of these Brominated epoxide non-woven / woven E-glass reinforced laminate sheets.
By applying BS EN 61249-2-42, you can ensure the reliability and sustainability of these materials in different climatic conditions. This helps in manufacturing good quality brominated epoxide non-woven / woven E-glass reinforced laminate sheets used in printed boards.
