摘要： The invention relates to joining of fine wires, and more particularly to a wire bonding method suitable for connecting a number of wires within a narrow area. A first wire is bonded on a pad, and a second wire is bonded on the position where the first wire has been bonded. Bonding of a subsequent wire is performed in that the wire is stacked and bonded in similar manner mentioned above. Thus a plurality of repair wires can be bonded within one pad even if the pad area is very small.

摘要： An electromechanical branching filter capable of branching an input electrical signal into two output signals having different frequency components. It includes a wide bandpass filter section and a narrow bandpass filter section, both sections being mechanically connected to a common input transducer through coupling means including a coupler whose coupling coefficient is in the range of .+-.30 % of the geometric mean value of the fractional bandwidths of the two filter sections.
