日本のアピックヤマダ㈱は世界中の電子工業界に製品を供給する主要な会社ですが、そのため”超精密と品質”は同社の本性となっています。同社は、１９５０年設立、精密機械産業が集結しているので東洋の「スイス」と言われる長野県に本社を置き、広範囲の半導体製造に関する製品を生産しています。
この重要な日本企業は1969年にはすでに日本で初めてモールド金型の製造を始め、1971年にはリードフレームの製造を開始し,1972年には半導体組立て製造装置の製造に着手し、1981年にはその自動化を成し遂げました。
バイスプレジデント近藤 正 – “我々は当社の職人技能を誇りに思っています”
同社における半導体樹脂封子設備事業は売上高の約１/３を担っていますが。モールド金型カンパニーはその樹脂封子用金型を生産し国内外の顧客に提供しています。”近年顧客の成型品品質への要求が一段と厳しくなっている中、より高度な加工技術を必要とする1番型を得意とし、他社に出来ない金型作りをします。”
“This has become increasingly important for us as the challenges from our customers - from prototyping to full production – have become even greater,“ explained Vice-President, Mr. Tadashi Kondo. “We are proud of our craftsmanship and the skill of our workforce and, with the help of System 3R tooling, we are able to produce high-quality dies that cannot be made by other firms in Japan.”
VDP – tool life has doubled, surface roughness has been improved and machining time has been halved
Macro tooling was first installed when they moved from manual die-sink EDM operation to more automated equipment. “We are grateful for the recommendation of System 3R that we received from the machine supplier, which gave us the repeatable accuracy that we were looking for,” said Supervisor, Mr. Takashi Katayama. “It proved so successful that we also use Macro on our ultra-precision and surface grinders.”
As with all global suppliers there is a constant need to look at costs and competitiveness and the next stage of palletisation was a logical move for the Company. This programme was led by Mr. Yoshio Watanabe, Production Engineering Manager, who had the confidence in System 3R when shown initial prototypes of the Vibration-Damped pallets to put them to the test.
They proved so successful that Apic Yamada were one of the first customers worldwide for MacroMagnum VDP pallets. “As a result of using VDP, tool life has doubled compared with conventional vices, surface roughness has been improved and machining time has been halved,“ said Mr. Katayama.
Once again, System 3R has shown the effectiveness of the ‘One System Partner’ approach to enhanced productivity and, like Apic Yamada, is contributing to more efficient manufacturing environments around the world.
