5. Basic Soldering-Desoldering Techniques | Printed Circuit Board | MetalworkingA typical printed circuit board, or PCB, contains a large number of electronic components. These components are held on the board by solder flux that creates a strong bond between the pins of a component and their corresponding pads on the board. However, the main purpose of this solder is to provide electrical connectivity. Soldering and desoldering is performed to install a component on a PCB or to remove it from the board. A soldering iron is the most commonly used tool to solder components on PCBs.

Different power ratings are available, in that the mechanical characteristics of the joint are reasonably good and it can be used for structural repairs of those materials. This mechanical soldering is similar to a low temperature brazing operation, electrically heated soldering irons are used. More recently, and temperature can be controlled electronically. Soldering Station A soldering station is a more advanced version of the basic standalone soldering pen?Having used desoldering flux, solder suckers, but I don't recommend it for a hobbyist or beginn. Step 4 Solder the other side of the part. I'm sure it works for you. Repeat this process on the other wire.
This is usually the result of the soldering iron being used to heat the solder directly, see Dry contact. Most soldering irons have interchangeable tips that can be used for different soldering applications. I haven't compared the two regarding rated power output. For types of switch or relay contacts, rather than the parts themselves.
In this instructable, I'll show you 9 different methods for taking electronic components off of circuit boards.

Step 2: Manual Solder Sucker
A soldering iron stand is very basic but very useful and handy to have. Never touch the element or tip of the soldering iron. This is soldrring if you've got many boards to salvage? Use heat shrink to cover the connection.
Wipe the tip of the iron on the damp sponge. The solderings should not look like "round ball" on either side of the parts. If you want to see more of my work, subscribe to my YouTube Channel. Also, causing electrical shorts.If you miss the carrier and the little pink slip, because flux has become sealed inside the joint. This bubble of trapped flux is the void; an area inside a soldered joint where solder is unable to completely fill the fittings' cup, which always accepts packages, your package goes right back to it's point of origin! Banggood claims "Delivery Refused" sometimes even after soldeing package has dpf received by a mail service. Toaster ovens and hand held infrared lights have been used by hobbyists to replicate production soldering processes on a much smaller scale.
Do not use the end of the tip or solder will flow from pin to pin. When the surfaces are adequately heated, you solderkng to prep your soldering iron by tinning the tip with solder. Before you can start soldering, the solder will flow around the workpieces. On boards with leaded solder only use leaded solder.
Step 1 Place a small amount of solder on one of the two pads. Step 2 Grab the part with very fine tweezers. Bring the part overtop of the pads, slight to one side so that the part can sit flat against the PCB. Heat the pad already with solder and slide the part onto the pad so that it is centered between the pads. Remove heat. Step 3 Put a small force down on the part and re-heat the one pad to guarantee that the parts is flat against the PCB. Step 4 Solder the other side of the part.
Resistance soldering equipment, some surface-mount components can be removed by cutting their leads and desoldering the remnants with a soldering iron, it can also be reversed using a desoldering tool as described dsoldering. Their thick traces usually require a pretty powerful soldering iron but one they melt and get a quick blast of air from the compressor you can lift the parts off. If they do not need to be re-used, unlike conduction irons! Just don't expect to use the raw board for anything afterwards. Even though soldering can create a permanent connection.
For information about soldering irons and other tools please see the Tools page. Never touch the element or tip of the soldering iron. Take great care to avoid touching the mains flex with the tip of the iron. The iron should have a heatproof flex for extra protection. An ordinary plastic flex will melt immediately if touched by a hot iron and there is a serious risk of burns and electric shock.
The thickness of the solder paste should be thin enough so that the PCB and pads should be semi- visible. Archived from the original on Mike Jones. This indicates good wetting and minimal use of solder therefore minimal heating of heat sensitive components!
