Abstract
A flexible circuit laminate is presented comprising a microglass reinforce fluoropolymer layer sandwiched between a fluoropolymer coated polyimide and a copper conductive pattern. The glass reinforced fluoropolymer acts as a high bond strength adhesive between the fluoropolymer coated polyimide and copper conductive pattern. The glass reinforced fluoropolymer also contributes to improved dimensional stability as well as improved electrical performance. Preferably, the microglass content is between about 4 to about 30 weight percent, and more preferably about 20 weight percent glass.
