I was ever provided with the right tool to make the job easier: an electric screwdriver. Electric screwdrivers provide major advantages for anyone working in electronics because they pack power, precision, and an On/Off switch into a convenient and efficient tool. Using this tool will definitely save your time and energy on the job and, as an extra benefit, it is also easy to operate once you understand the basic operating steps.
Here are the general steps to follow when using a precision screwdriver
Using the right bit
It is important that you use the right screwdriver bit for the type of screw being used. Always make sure that the screwdriver bit is firmly seated in the screw head.
If you're not sure, hold the bit at a 45 degree angle. If the screw stays on the bit and doesn't fall off, you are using the right bit.
Firmly fitted bit
Always make sure that the screwdriver bit is firmly seated in the screw head.
As you are drilling, apply pressure to the top of the screwdriver to ensure that the bit stays in the screw head.
Press the backwards button to unscrew the screws. The screwdriver with more torque on reverse. 0.25N.m and make sure it rotates properly when removing the screws. If the screws are too solid to remove by the screwdriver, can use the pen screwdriver as a manual one, to loosen it a little first, then start to use electric power modes working. After everything is repaired/fixed, press the forward button to tighten the screws. Remember to ease back on the pressure when the screw is almost in place. Too much pressure and you will end up sinking the screw too deeply into the board or hole.
The more you drive in screws, the more you know what works best for you.
