Soft termination

“Flex Crack” and “Thermal Shock Crack” are the most serious extrinsic defects of MLCC except for intrinsic defects derived from MLCC manufacturing process. There are a few methods to overcome this issue. “Soft termination (metal-epoxy)” technique is one of the most effective method, which can minimize flex and thermal shock crack.

FM can provide various high-quality pastes for soft termination; Ag-epoxy (AST-series), Ag/Cu-epoxy (ACST-series), and Cu-epoxy (CST-series).
FM’s pastes for soft termination have the following merits.
- Easy work and store
: They have very stable viscosity at room temperature, so they can be stored and used at room temperature.
- Low elastic modulus and high flex strength
- Strong adhesion and heat-resistance
: After solder heat test at 290℃ for 10sec., there is no peeling or crack.
- Good plating quality
: CST series as well as AST and ACST series can give good plating quality.
- Good electrical contact similar as normal Cu termination
- Better MLCC reliability
