Alternatively, you can use a soldering iron to heat the paste, although it's a little tricky to get it right at the first attempt. But for most people, an economical way is to instead use a heat gun. Ideally, this is done by passing the circuit board through an infrared reflow oven. Be gentle and extra careful when you do this, and ensure the components are aligned properly.įinally, you need to apply heat to melt the solder powder in the paste, so it can create a bond between the components and the board. In the case of the latter, you'll need to use a squeegee to even out the paste on the mounting area.Īfter this, place the components on the circuit board. You can do this using a syringe or stencil. It includes a 100 grams, 0.6 mm diameter, 60-40 Sn/Pb rosin core solder wire, a rosin paste flux, 2 mini screwdrivers, and 2 stranded 22 AWG connecting wires. Assuming you've got the PCB and the components you want to install on it handy, here's a quick overview of how to use solder paste.įirst, apply the solder paste to the area where you want to mount the components. Likewise, make sure your solder paste is at room temperature. But before starting, make sure the circuit board and the components you want to solder are clean. Flux facilitates this soldering process by cleaning the metal surfaces before they are fused. This is where flux comes into play.Using solder paste is pretty easy. Solder is a combination of metal alloys that, after melting, fuses the pin of a component to a metal pad or hole on a circuit board to create an electrically conductive connection. Rosin core soldering flux pyrolysis products, Rosin flux pyrolysis products Pyrolysis products of rosin core solder include acetone, aliphatic aldehydes. However, during the soldering process, various impurities, oxides, and contaminants can hinder the formation of a strong bond. Soldering involves joining metal surfaces using a molten alloy known as solder. It increases the wetting ability of the solder, causing it to flow more uniformly over surfaces without balling-up (dewetting).įlux plays a crucial role in electronic soldering, facilitating the process and ensuring reliable connections between components. Rosin-based fluxes are non-corrosive at room temperature, hygroscopic, and normally cure at room temperature to entrap potentially corrosive activators. This article covers the types of fluxes available, the advantages and disadvantages of each, and options for flux removal.įlux aids in soldering and desoldering processes by removing oxide films which form on the surface of metals being soldered. That ensures the solder joint doesn’t crack or come loose even with the day-to-day wear-and-tear. When joining two metals in a soldering process, like used in PCB assembly, flux is required to achieve a true metallurgic bond. It is frequently used to join wires to leads of components such as switches or to join components of all kinds to a printed circuit board. Hello friends, how is rosin used when soldering This is a very basic question when soldering, but someone asked me how to use it Nowadays we rarely use rosin alone when soldering Love.
