Rosin flux paste vs tinning flux9/17/2023 Solder paste makes an electrical connection between them in addition to a mechanical one. It permits the assembly of PCBs and the joining of electrical wires with solder paste. Solder paste is a reasonably good electricity conductor. The various types have a range of solder ball sizes between which 80% of the tiny solder balls fall because they cannot be precisely graded. The small solder balls are used to classify the solder paste. Solder paste comes in a variety of grades, and the right one can be chosen depending on the PCB assembly method being used. The flux serves as a temporary adhesive to hold the surface mount components in place in addition to performing its regular function of cleaning the soldering surfaces of impurities and oxidation. Metal solder particles and a putty-like flux are combined to form a solder paste, which has the consistency of a powder. The “flux” organic chemical cream is typically protected by patents and/or trade secrets. How do you make solder paste?Ī metal alloy powder (about 90% by weight) and a cream-like substance made of organic chemicals (about 10% by weight) are combined to create solder paste. It is simpler to apply solder flux evenly to the entire soldering area when solder paste grease is used. It is advantageous because when heated by the soldering iron, it “sticks” to objects and spreads out around the area being soldered. Solder flux and petroleum jelly are combined to create solder paste grease. How long does solder take to dry?

Shelf life is general 6-12months from the date of manufacture when handled properly and held at 5-8☌. The typical peak temperature will be 235°-245☌ degrees with 60-90 seconds over reflow (217☌). in a leadfree application the soak zone time (150°-217☌) can be 60- 90 seconds. The typical peak temperature will be 205°-215☌ degrees with 60-90 seconds over reflow (183☌). In a leaded application, the soak zone time (150☌-184☌) can be 60-90 seconds. This allows the use of tacky flux in a leaded or lead-free application.
