Solder Paste
ICT testable no-clean / cleanable Low Cost High Reliability Solder Paste (1.1Ag)
- S1XBIG58-M650-7
The BIG series is a high reliability alloy with improved thermo-mechanical stress durability using unique alloy strengthening technologies, while realizing a reduced low silver content (1.1% Ag), offering lower material costs. Its thermal cycle resistance and joint strength exceed SAC305. Innovatively engineered, the low stickiness of the flux residue prevents adhesion to test pins, improving ICT first pass yield. It also offers excellent cleanability, making it suitable for both no-clean and clean applications.
feature

High ICT first pass yield
S1XBIG58-M650-7 prevents the buildup of thick and sticky flux residue over the solder joint,
which helps the testing probe to get the accurate readings to improve the first pass rate.。
Superior wetting ability prevents voiding
For smaller components such as QFNs, micro BGA and LGA, bigger voids could occupy majority of the pad area thus creating a possible weak link for failure. S1XBIG58-M650-7 has specially designed flux to effectively reduce the amount of gas generated thereby minimize the amount of voids.
“Halogen-free”addressing the environment
One keyword of environmental measures is “halogen-free”; these days companies demand final products to be halogen-free.
Halogen-free S1XBIG58-M650-7 meets such demands while providing both reliability and workability.
