BS EN 61249-2-4 is the second part of the multi-series standard used for interconnecting structures. This helps in manufacturing good quality polyester non-woven/woven fibreglass laminated sheet used in interconnecting structures.
BS EN 61249-2-4 specifies the requirements for properties of polyester woven fibreglass reinforced surface/non-woven fibreglass reinforced core copper-clad laminated sheet, of defined flammability, in thicknesses of 0,80 mm to 1,60 mm.
Some property requirements may have several classes of performance. The class desired must be specified on the purchase order, otherwise the default class of material will be supplied.
BS EN 61249-2-4 on printed boards and other interconnecting structures is useful for:
Printed boards mechanically support electronic components using conductive pads in the shape designed to accept the component's terminals. This helps in connecting these PCBs electrically by using traces, and planes.
BS EN 61249-2-4 specifies the materials to be used in the interconnecting structure according to their operational requirement. This helps in determining the electrical properties of these copper-clad laminate sheets. With the help of these non-electric copper properties, you can avoid defects and ensures the dimensional stability of these copper-clad laminate sheets. Non-electrical properties of the base material after the removal of the copper foil help in ensuring the flexural strength, flammability, and water absorption in this copper-clad laminate sheet.
By applying BS EN 61249-2-4, you can manufacture good quality Polyester non-woven/woven fibreglass laminated sheets used in printed boards and other interconnecting structures.
