explain the function of the following tools when used for maintenance i. desoldering pump, ii. long nose pliers, iii. logic probe (july 2019)

i. Desoldering pump:

A desoldering pump, also known as a soldering iron, is a tool used to remove solder from electronic components and circuit boards. It consists of a heating element and a plunger that is used to suck up the molten solder. The desoldering pump is often used during maintenance to remove faulty or damaged components from circuit boards, or to repair connections that have become loose or broken.

ii. Long nose pliers:

Long nose pliers are a type of hand tool with long, pointed jaws that are used for gripping and manipulating small objects. They are often used during maintenance to reach into tight spaces or to hold and position components.

iii. Logic probe:

A logic probe is a testing tool used to test digital electronic circuits. It consists of a probe with a light or sound indicator that is used to test the state of a circuit. The logic probe is often used during maintenance to troubleshoot and diagnose problems in digital circuits. It can be used to determine if a circuit is in a high or low state, or to identify fault conditions such as open or shorted circuits.
