Palladium-Coated Copper Bonding Wires (PCC Bonding Wires)
Obtaining advantage in both cost and performance
It is a copper bonding wire covered with palladium on the wire surface.
Cost reduction is achieved with high bonding properties and bonding reliability.
CHR-1BK (High-Reliability Standard PCC Bonding Wire)
■Features
- High bonding reliability is obtained by stable palladium distribution to FAB surface layer
- High and stable stitch bondability
- Wide bonding window
■Reliability
Three types of reliability evaluation shown in the table below are widely used to check the reliability of interconnecting components using copper wiring in automotive products.
Evaluation is conducted under AEC-Q006 Grade0 standard and items that satisfy the criteria are marked in blue.
HTSL: High Temperature Storage Life
uHAST: unbiased Highly Accelerated Stress Test
TCT: Temperature Cycling Test
