Solder paste is a mixture of solder powder and gel-like flux.
When heated, the powder fuses in a flux environment, forming a brazed joint.
ROL1 class flux gel, most suitable for refurbishment and small batch production.
Medium-temperature solder paste is optimal for critical soldering of SMD elements with a pitch of 0.3 mm.
Very good wettability.
It is also used for assembling double-sided printed circuit boards when soldering the first side of the board (the second is soldered with low-temperature paste).
Specifications:
Chemical composition of the solder alloy in percent:
-
Sn (tin) - 62%
-
Pb (lead) - 36%
-
Ag (silver) - 2%
Temperature range:
-
preheat: 90-150°C
-
reflow start: 178°C
-
soldering temperature: 190°C - 210°C
-

The viscosity of the paste is optimal for applying to the board through a stencil.
Packing: medical syringe 5 ml (weight 25 grams).
Storage conditions: at temperatures between+5°C and+15°C, try to avoid direct sunlight.
Shelf life: 6-8 months, then the properties of the paste deteriorate.
