DESCRIPTION
BS EN 61249-2-44:2016
This standard BS EN 61249-2-44:2016 Materials for printed boards and other interconnecting structures is classified in these ICS categories:
- 31.180 Printed circuits and boards
This part of IEC 61249 gives requirements for properties of non-halogenated 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 non- halogenated 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.
