What is BS EN 61249-2-27 - Clad and unclad materials used in printed boards about?
BS EN 61249-2-27 is the second part of an international standard used for printed boards and other interconnecting structures that specifies the properties of clad and unclad materials.
By using BS EN 61249-2-27 you can manufacture good quality printed boards and other interconnecting structures.
BS EN 61249-2-27 specifies the requirements for properties of bismaleimide/triazine modified with non-halogenated epoxide woven E-glass reinforced laminated sheets of defined flammability (vertical burning test), copper-clad in thicknesses of 0,03 mm up to 1,60 mm. The flammability rating is achieved through the use of non-halogenated inorganic and/or organic compounds acting as fire retardants. These fire retardants are contained as part of polymeric structure or in addition to it. The glass transition temperature is defined to be 160 °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 maybe supplied.
Who is BS EN 61249-2-27 - Clad and unclad materials used in printed boards for?
BS EN 61249-2-27 on Materials for printed boards and other interconnecting structures is useful for:
- Aerospace
- Manufacturer of aircrafts
- Manufacturer of electronic components
- Manufacturer of automotive parts
- Electronic engineer
- Aeronautical engineer
Why should you use BS EN 61249-2-27 - Clad and unclad materials used in printed boards?
Printed circuit boards (PCBs) are used to mechanically support and electrically connect electronic components. These components are connected by using conductive pathways, tracks or signal traces etched from copper sheets laminated onto a non-conductive substrate.
BS EN 61249-2-27 specifies materials that can be used in constructing these printed circuit boards according to their operational requirements. This helps in determining the electrical properties of clad and unclad materials used in printed boards. These non-electric properties of copper-clad laminate help in avoiding the defects which directly impacts the materials which are to be used in the manufacturing process.
By applying BS EN 61249-2-27 you can manufacture good quality copper-clad sheets used in printed boards.
