New solderless connection technology using light-setting insulation resin

Koichi Nagao; Kazunari Nishihara; Hiroaki Fujimoto; Kenzo Hatada

A new solderless connection technology using light-setting insulation resin has been developed. This makes possible fine-pitch and short length connection between the FPC (Flexible Printed Circuit) and the electrodes of an electronic device. An FPC is attached by the adhesive force of the light-setting insulation resin. This technology has been applied to a thin-film magnetic head, and realized ultra fine connection, i.e. a connection pitch of 75 /spl mu/m (present ratio 1/2) and a connection length of 250 /spl mu/m (present ratio 1/10).<<ETX>>
