MK GOLD
BONDING WIRE
| INTRODUCTION
Since 1971, MK
Gold Bonding Wire has been developed into
various types of gold bonding wire for semiconductor packaging, covering
TR to Ultra Fine Pad Pitch package. MK
Gold Bonding Wire promises the best
production yield for your new Fine Pad Pitch bonding. There are many
problems such as ball neck damage, wire sagging, etc. that cannot be
allowed in high speed bonding, automatic bonding, ultra thin package (TSOP,
TQFP:1mm thickness or less) and lead on chip package. Under the concept of
zero defect, there are six different types of gold bonding wire for
conventional and new package application.
|
M TYPE |
|
High
speed bonding wire. |
|
|
T TYPE |
|
High
speed and high strength bonding wire. |
|
|
L TYPE |
|
High
speed and low loop bonding wire. |
|
|
R TYPE |
|
High
strength wire for special package (BGA). |
|
|
U TYPE |
|
High
strength 4N wire. |
|
|
X TYPE |
|
