Description
(実施例)
(1)80μmのNi粒を水素雰囲気中で加熱して表面を清浄化する。
(2)表面が清浄となったNi粒10gと、ペースト状フラックス90gと、Sn-3Ag-0.5Cuの粉末はんだ90gを混練してペースト状の混合物にする。該混合物を鋳鉄製の柄杓の中に入れ、柄杓をガスコンロで加熱して粉末はんだを250℃で溶融させると同時に溶融したものを金属製ヘラで約30秒間攪拌してから、5×10×50(mm)の鋳型に鋳込んで棒状の混合母合金を作製する。この母合金のNi粒の含有量は10質量%である。
(3)Sn-3Ag-0.5Cuの鉛フリーはんだ約80Kgを溶解釜で溶解しておき、該溶解釜から溶融はんだ10Kgを溶融金属注湯装置に入れるとともに、前記混合母合金30gを溶融金属柱等装置に入れて攪拌装置で約10秒間攪拌する。その後、Ni粒が分散された溶融はんだをビレット用の円筒型鋳型に鋳込み、鋳型を急冷してビレットを作製する。
(4)ビレットを押し出し装置で厚さ5mm、巾20mmの棒状はんだに加工し、該棒状はんだを圧延機で厚さ0.1mm、巾15mmに圧延して板状はんだに加工する。そして該板状はんだをプレスで打ち抜いて10×10(mm)のペレットに成形する。
(1)80μmのNi粒の表面にCuの電解メッキを行う。
(2)表面にCuメッキされたNi粒10gと、ペースト状フラックス10gを混練してペースト状の混合物にする。
(3)Sn-3Ag-0.5Cuの鉛フリーはんだ約80Kgを溶解釜で溶解しておき、該溶解釜の中の溶融はんだ中に前記ペースト状混合物160gを投入する。ペースト状混合物を投入後、金属製ヘラで溶融はんだを約60秒間攪拌して溶融はんだ中にNi粒を分散させる。その後、Ni粒が分散された溶融はんだをビレット用の円筒型鋳型に鋳込み、鋳型を急冷してビレットを作製する。
(4)ビレットを押し出し装置で厚さ5mm、巾20mmの棒状はんだに加工し、該棒状はんだを圧延機で厚さ0.1mm、巾15mmに圧延して板状はんだに加工する。そして該板状はんだをプレスで打ち抜いて10×10(mm)のペレットに成形する。
Claims (4)
