IPC: C23C2/28
Filed: 1997-03-26
Abstract: PROBLEM TO BE SOLVED: To form a Zn-Fe alloy plating layer of specific iron content and to produce a plated steel sheet excellent in plating adhesion by cooling an annealed steel sheet at specific cooling velocity, applying hot dip galvanizing to the steel sheet, regulating coating weight, and subjecting the plated steel sheet to temp. raise and to holding to and at a specific alloying temp. SOLUTION: After a degreased and pickled steel sheet is annealed, rapid cooling is performed at a rate of >=10 deg.C/sec to apply stress. After the temp. of this steel sheet is regulated to the prescribed temp., hot dip galvanizing is applied, and successively, coating weight is regulated. Subsequently, the hot dip galvanized steel sheet is subjected to temp. raise at a high rate of >=30 deg.C/sec up to an alloying temp. of 475-510 deg.C and held at this temp. until alloying treatment is completed. By this procedure, a Zn-Fe alloy plating layer of 8-11 wt.% iron content is obtained without developing Γ-phase. Further, it is preferable to cool this steel sheet, after the completion of alloying treatment, down to 420 deg.C at a high rate of >=30 deg.C/sec to prevent the formation of Ζ-phase.

Abstract: PROBLEM TO BE SOLVED: To prevent moisture resistance defects while suppressing manufacture cost increase. SOLUTION: A wire 22 bridged between each electrode 21a of a pellet 21 and the inner part 19a of each lead in a QFP(Quad Flat Package) IC 27 is resin-sealed by a resin-sealing body 26 formed of material which contains resin. In this case, the coated wire 22 is coated in such a way that a moisture resistance improving film 24, which is formed of the resin of the resin sealing body 26 and epoxy resin which allows high adhesion to the wire main body 23, is not present at some area. Therefore, water invaded from a space between the resin of the resin-sealing body 26 and the lead is interrupted and does not reach the electrode 21a of the pellet 21, and corrosion of the aluminum electrode and wiring is prevented.  Since the moisture resistance improving film 24 is sufficient in the condition that it is not applied on some area, the use of the coated wire suppresses the manufacture cost increase of IC.
