Web15. In order to make the soldering tip last longer, keep it clean and also tinned. Heat the tip and add a little amount of solder to cover the tip. Then wipe it off on a wet sponge removing everything except a thin layer of solder. This would help in making the tip last longer and will also speed up the heat transfer. Weblocal meniscus, depressing the wave. The chamfer reduces the possibility of skipped joints around the edge of the board. The edge surface used to support the board during soldering should be as small as possible 2-3mm. If it is a large area flux will seep into this gap and will tend to spit during soldering possibly causing solder balls.

WebTypes of solder. · 60/40 solder– its composition is 60% tin and 40% lead. It melts at 374oF. It forms high, rounded, beaded seams. Because of its low relatively melting point this type of solder is easy to rework to maintain a smooth finish. · 50/50 solder– its composition is 50% tin and 50% lead. Reflow soldering is a process in which a solder paste (a sticky mixture of powdered solder and flux) is used to temporarily attach one or thousands of tiny electrical components to their contact pads, after which the entire assembly is subjected to controlled heat. The solder paste reflows in a molten state, creating permanent solder joints. Heating may be accomplished by passing th… jira issue fields condition
