Desoldering Methods

Dear Solderman, i hope you know how to dessolder a wave soldered component from a board. There is problem because the pins are two face soldered. - thanks

mail from JS

Sending a few sites, read them all and then tell me.

Desoldering - Wiki

A component with one or two connections to the PCB can usually be removed by heating one joint, pulling out an end of the component while the solder is molten (bending the other lead to do so), and repeating for the second joint. Solder filling the hole can be removed with a pump or with a pointed object made of a material which solder does not wet, such as stainless steel or wood.

How to Desolder

One of the most frustrating parts of building electronic circuits is getting something wrong. For a board that should take ten minutes to put together, you could spend an hour just trying to fix a component that you got backwards. Sadly, desoldering it’s not as easy as soldering in reverse.

Desoldering requires two main things: a soldering iron and a device to remove solder. Soldering irons are the heat source used to melt solder. Irons of the 15W to 30W range are good for most electronics/printed circuit board work.

Desoldering THM and SMT

Desoldering is a topic that no one seems to get to excited about until the time comes when people discover that a lot of damage is being done during this operation.

Working with SMD and SMT PCB

One thing tho, i would like to request you to send me some procedures on how to work with surface mount devices (SMD's). I cant get the IC as DIP so i have no choice but improvise an SMD. What is your most professional advice on this? Is it possible you could help me with any procedures for using an SMD on a PCB circuit?.

you may need a big tabletop magnifier with light and a fine tip soldering iron to get started. It may be difficult and needs a lot of practice, but many people are able to do it.

Surface-mount technology - Wiki

An SMT component is usually smaller than its through-hole counterpart because it has either smaller leads or no leads at all. It may have short pins or leads of various styles, flat contacts, a matrix of solder balls (BGAs), or terminations on the body of the component.

Introduction to Surface Mount Technology and Surface Mount Devices

By Dean F. Poeth, II, Ph.D., P.E., C.Mfg.E.
For the Small Manufacturer and Hobbyist: Prototype Manufacturing, Rework, and Repair Techniques

SMDs have improved performance over through-hole components due to their smaller size, shorter internal leads, and smaller board layouts. These factors reduce the circuit’s parasitic inductance and capacitance. SMDs can also be more cost effective than traditional through-hole components due to the smaller board size, fewer board layers, and fewer holes.

Hints and Tips for using Surface Mount Technology (SMT) 

What is Surface Mount Technology? Put Simply - It is a type of electronic component
package. Most electronic components can be divided into two categories - through hole (TH)
and surface mount (SM). Through-hole components have been used for many years and are
designed to be loaded on one side of a printed circuit board (PCB) and soldered on the other.
SM components are designed to be loaded and soldered on the same side of the PCB.

Soldering Iron Tip

Can I use stainless steel to replace a defective soldering iron tip?

mail from EA

Soldering iron tips are mostly alloys of copper. the thermal conductivity of steel is poor. buy a soldering iron tip available in the local market.

Weller tips are magnetic and only original weller tips to be used.

Changing the soldering tips on a PES51 pencil is very simple. You just have to make sure to take your time and don't force anything. Damaging your iron is not only possible, but easy when replacing the tips, so proceed with care.
