Question

When handling circuit boards, an individual should not Touch the metal case to the circuit board Hold the circuit board by its edges only Use a concrete or wooden flooring room Touch the components to determine if they are damaged Tinning a tip prevents corrosion and oxidation of the soldering tip True False A component lead is always electrically connected if it seems attached to the circuit board pad. True False All electrical components are harmless when the power is turned off from a circuit. True False When handling circuit boards, an individual should not Touch the metal case to the circuit board Mold the circuit board by its edges only Use a concrete or wooden flooring room Touch the components to determine if they are damaged

Explanation / Answer

--When handling the circuit board, an individual should not ---touch the componet to detemine if they are damaged becuase Electrostatic discharge can damage the component.

--Tinning the tip means covering the tip with a layer of solder.Tinning the tip extends the life of the tip by preventing oxidation and corrosion. because the tip is not coming in contact to air.--true

--A component lead is always electrically connected if it seems attached to the circuit board pad--true because to avoide loose connection.

--All electrical component are harmless when the power is turned off from the circuit--false because there will be a possibility of a storage element and that may create problem.
