ECOREL FREE 300-31A
Very good wetting, especially on copper surfaces
- N96,5AG3,5 lead free solder paste
- No clean SMT printing process
- Excellent low voiding for DCB
ECOREL FREE 300-31A
Is especially designed to minimize flux spattering, solder leaking and voiding to achieve consistent bond-line thickness (BLT) between the large chips and the DCB substrate. Oxide layer formation on copper surfaces causing color change is efficiently inhibited to achieve a shiny surface with nice surface cosmetics.
Sn96.5Ag3.5 alloy is an excellent option for DCB materials because of its good wetting properties, allowing easy flow and strong bonding. Additionally, it has been shown to have higher reliability compared to other alloys, making it more resistant to thermal fatigue and stress factors. Its strong, ductile joint can withstand mechanical stress and vibrations. Its lower melting, compared to alloys Like SnSb or leaded pastes makes it suitable for soldering heat-sensitive components.
The chemistry of this product is also available with other alloys or particle sizes on request.
