Can Soldering be Difficult?įREE SHIPPING on orders under 13oz - NO MINIMUM The solder on each surface should flow quickly remove the iron and when the solder hardens, both the components should be soldered together. With a nicely tinned tip and surface, simply touch the two pieces being solder together with the iron. The solder should flow evenly over the entire pad and once it does remove the iron and let the solder firm up.įinal Connection: At this point all the hard work is done. Apply a tinned tip iron to the solder pad and begin applying solder to the pad. Also, in the example in our video the solder pad surface getting tinned too. Remember the suggestion above about the rosin being in the middle of the solder using the middle of the solder helps it stick to the wire better. Similar to tinning an iron, the wires get a thin layer of solder applied to them it’s important that the solder sticks to the wire. Tin the Surfaces (Wires, Solder Pad or PCB): In our video we show an example of soldering wires to a Cree LED star, but before making the final connection the wire leads are first tinned. Having & Maintaining the Right Tools for the Trade This gets the rosin flux on the surface first and aides in getting the solder to adhere to the surface. Because getting solder to flow and stick to a surface is sometimes difficult, knowing the flux is in the center of the solder means you can help avoid that problem by purposefully melting the center of the solder directly to the surface. The rosin core is worth mentioning because it removes impurities on the contacts and improves the electrical connection basically, it helps the solder stick to the contact pad. Solder is normally 60 percent tin and 40 percent lead with a rosin flux core (center of the solder). Most of the soldering we encounter is with LEDs on MCPCB, which you can see on the right and we show an example of in the video below. Another common type of solder connection is found on PCBs and MCPCBs, where there are conductive traces in a board that lead to components where a solder connection is made. A standard ‘point-to-point’ connection is two leads, lets say the cathode of an LED and the anode of a second LED twisted and soldered together this is more efficient than simply just twisting leads together. Solder is a conductive material that melts around 400 degree Fahrenheit and allows two pieces of metal to connect in a circuit.
