How do you remove cold solder joints?
Repair: Cold joints can usually be repaired by simply re-heating the joint with a hot iron until the solder flows. Many cold joints (such as the one pictured) also suffer from too much solder. The excess solder can usually be drawn-off with the tip of the iron.
How do you remove solder without heat?
Touch the cold flat head screwdriver to the liquid solder, and quickly remove it. If done properly, the solder should adhere to the cold screwdriver and can be removed from the surface. This process can be repeated to remove any remaining amount of solder.

What tool is used to remove solder from the PCB?
desoldering pump
A desoldering pump, colloquially known as a solder sucker, is a manually-operated device which is used to remove solder from a printed circuit board. There are two types: the plunger style and bulb style. (An electrically-operated pump for this purpose would usually be called a vacuum pump.)

How do you fix a cold soldering iron joint?
Soldering iron with a tip that attains and maintains adequate temperature. To correct a cold solder joint, desoldering or removing the solder is not necessary. Simply add flux to the solder joint and reflow the solder by making contact with the tip of the soldering iron.
How to test for cold solder joint with a multimeter?
When testing for cold solder joint using a multimeter, there are two measures you can use to establish a cold solder joint. These are: Here you will begin by switching the multimeter to measure resistance. Often this will be indicated by the Ohm (Ω) symbol.
What is a disturbed joint in soldering?
1 A disturbed joint: formed when a solder joint is disturbed before the molten solder solidifies 2 A cold joint: one where the solder fails to melt entirely after soldering. 3 An overheated joint: this problem occurs when the soldering wire fails to melt despite heating.
What are the most common soldering mistakes?
Some of the common soldering mistakes you might make during making solder joints include: 1. A disturbed joint: formed when a solder joint is disturbed before the molten solder solidifies 2. A cold joint: one where the solder fails to melt entirely after soldering.
