Preformed Solder Solder Tabs High Lead High Melting Point
Product Description
Product name: Pb92.5Sn5Ag2.5 prefabricated solder
- High lead, high melting point (287/296℃)
- Good mechanical properties
- Good thermal fatigue performance
- Excellent wettability
- High reliability, supported by long-term reliability data
- High content of Pb
Pb92.5Sn5Ag2.5 is a high-lead solder with high melting point
(287/296°C) and high lead content [w(Pb)>85%]. It is a
high-temperature soldering material with good flow and corrosion
resistance. , good mechanical properties and process performance,
and low cost, it is still irreplaceable in the current brazing
field; adding an appropriate amount of Ag to high-lead solder can
improve the heat-resistant temperature of the brazed joint, so that
it can be adapted to high-power devices. The package has high
reliability requirements for solder.

Operation details:
- Solder pick up:
Use an anti-static jig to pick up the solder to prevent solder
contamination and deformation.
- Flux Compatibility:
Pb92.5Sn5Ag2.5 solder is compatible with the major no-clean and
water-soluble electronic grade fluxes currently on the market.
