The present invention relates to a method in which a terminal establishes component carriers in a wireless communication system. The first polymer optionally has a crosslinked core and has a glass transition temperature in the range of \u221230\xb0 C. 02 mil thick copper cladding thereon its first planar surface that has been affixed atop a hydrophillic layer, and an adhesive layer on its second planar surface. The high voltage generator generates erase voltages for an erase operation according to the erase instruction signal.
