Title:
ANTICORROSIVE INK JET PRINTER HEAD AND METHOD OF MANUFACTURING THE SAME
Document Type and Number:
Japanese Patent JP3539456
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a bonding free from thermal damage and improve corrosion resistance by forming bonded members of an ink jet printer head by an alloy of a specified composition which contains Sn-Ni as a base and an additional metal optionally selected from Cu, Pd, Au and Ag.
SOLUTION: Applied on substrates 5 of respective bonded portions being bonded and constituting an ink jet printer head are a Cu element plating 6, Ni plating 7 and Sn plating 8 as a Sn plating layer, in this order. Sn, which is a plating material, and Ni and Cu, which are plated on the substrates, are fully diffused by heat treatment. In this case, the composition of a resulting alloy contains Sn of a percentage content of 35 to 95wt.%, Ni of a percentage content of 5 to 60wt.%, and Cu and the remainder of percentage contents, of which sum is 5wt.% or less. Accordingly, the bonded portion applied with plating of Sn/Ni/Cu and the like are all formed with a Sn-Ni alloy of excellent corrosion resistance.
