Title: Adjusting method for accumulator/isolator
Inventor: TAKEDA TSUYOSHI
IPC: H01P1/38
Filed: 1988-11-09
Abstract: PURPOSE:To attain adjustment without spoiling reliability by performing impedance matching by applying resin on a capacitor. CONSTITUTION:The impedance matching is performed by applying the resin on the capacitor 101. Namely, the capacitor 101 is covered with silicone resin 102 (epsilon=3.0). For instance, in a figure where frequency is put on an absissa and insertion loss and isolation are put on an ordinate, f+, f- are the upper and the lower limits of using frequency respectively, and curves shown by full lines are the characteristics of this example, and the curves shown by broken lines are the characteristics of conventional one. Thus, the isolator with the characteristic meeting the using frequency can be constituted. The resin to cover the capacitor fulfills a role to adjust finely the capacity of the capacitor and acts a function to protect the capacitor.

Abstract: PURPOSE:To obtain a lead frame base for a semiconductor device which can be soldered at a low temperature even without flux by providing a gloss Ni plating layer on a base of a lead frame made of copper or copper alloy, and laminating an Ni-Fe-P alloy plating layer thereon. CONSTITUTION:The thickness of an Ni-plating layer 2 to be provided on a substrate (Cu or Cu alloy) 1 for a semiconductor substrate needs 2mum or more so as to suppress diffusion of the Cu from a substrate material and to obtain wire bondability. An Ni-Fe-P alloy plating layer 3 is thinly provided with the layer 2 as a base, and two gloss Ni/Ni-Fe-P layers are laminated by plating on the substrate Cu. However, since the layer 3 is very hard and brittle, it is improper to solely adhere it thickly, and its thickness is set to about 0.20mum. As a result that composition is analyzed by collecting part of the Ni-Fe-P alloy plating layer, if about 1-5wt.% of Fe and 3-15wt.% of P are contained, it is discovered that solder wettability is best at a soldering temperature of 280 deg.C even without flux.
