Index• LCD manufacturing process

– Lithography ( 노광 )– Etching ( 식각 )– Deposition ( 증착 )

• Copper line manufacturing process– Heat treating ( 열처리 )– Machining ( 기계 가공 )

• Board manufacturing process– Soldering & assembly ( 납땜 & 조립 )

• Case manufacturing process– Plastic injection ( 사출 )

Copper line manufacturing process• Casting• Copper (Cu), Melting temperature - 1085℃• Very flexible, Good for large parts• SCR (Southwire Contiuous Rod System) - dissolved, etracted(8~9mm)

Copper line manufacturing process• Machining Wire Drawing( 신선 ) Stranding( 연선 ) Insulating( 절연 ) Cabling( 연합 )

Plastic Injection’s advan-tage

-Big size products can make

-Can make a free-form

-Short cycle time

-Good Productivity
