デュエルビッツ 入金不要ボーナスh Conductivity Copper Alloy KLF™ 170
CDA No. 19170
KLF™ 170 has デュエルビッツ 入金不要ボーナスvity equivalent to C19400 and strength equivalent to 42 alloy.
Good Points
- Has high electrical and thermal conductivity. デュエルビッツ 入金不要ボーナスvity is equivalent to C19400 class.
- Has デュエルビッツ 入金不要ボーナス with good electrical conductivity. Has excellent strength of 42 alloy class. (Temper ESH)
- Has good stamping formability and etching formability, resulting in no smut contamination in the etching process or
pre-plating process. - Has good solderability and platability. Protrusions in the silver plating are reduced.
- Has good bare bondability by gold wire and copper wire. Also applicable for direct bear wire-bonding without plating.
