49500WS
Description
The 49500WS
Sn100e Water Soluble Solder Wire
is an electronic grade solder wire. It uses a high-purity,
eutectic 99.5% tin, 0.5% copper, and cobalt alloy, which is complemented with a water-soluble flux core.
The 49500WS solder meets J-STD-004B, ASTM B 32, and exceeds J-STD-006C specifications.
This solder is a great lead-free alternative to leaded solders. It generally provides better wetting, contact
angle, flow, and visual appearance than typical Sn63/Pb37 no clean solders, while still delivering excellent
performance characteristics. It offers superior solder penetration into plated through holes and surface
mount interconnects. Further, it is a suitable replacement for SAC305 solder since the 49500WS forms
brighter, shinier, and less grainy joints. Furthermore, it is less expensive.
The 49500WS solders achieve a consistent solder and flux percentage through a state-of-the-art,
extrusion, wire-drawing machine. This machine continually monitors the wire to prevent voids and ensure
consistency, providing a top-grade solder wire.

Flux Core Properties
The rosin activated flux wets rapidly and is fast flowing. It will not decompose and carbonize under
prolonged heat. It is compatible with other water soluble organic fluxes.

Soldering Instructions
To achieve best hand-soldering results
1. Set the tip temperature between 370–425 °C [700–800 °F].
2. Place the solder tip in contact with the joint connection (lead/pad surface) at an angle of around
50° to heat the parts to be soldered.
3. While the soldering tip is applied, touch the solder wire to the opposite side of the soldering joint,
not to the soldering tip.
4. Immediately after the solder has flowed around the whole heated connection, remove the solder
wire and remove soldering tip from connection.
T

!
Do not move the connection while the solder is cooling.
W
