Complementary Metal Oxyde Semiconductor (CMOS) has one feature with a more flexible input voltage that is between 3.5 Volts to 15 Volts but, the input voltage exceeding 12 Volts will waste power. There are several things that need to be done to avoid damage to the CMOS IC before being paired into the circuit. This needs to be done because although the factory has been given protection in the form of diodes and resistors on the road entrance but this business has not guaranteed a hundred per cent . Action action to save CMOS type ICs.
- · CMOS ICs should always be provided with legs grown in plastic foil, not on foam or polistrin developed or in aluminum carrier material. CMOS ICs should not be removed from the packaging until they are ready to be paired to the circuit.
- · Be careful not to touch the CMOS IC pins before being mounted on the circuit because the electrostatic from the human hand can alter and increase the oxidation charge.
- · CMOS IC should be the last component to be attached to the circuit board. Do not insert or uninstall while the power supply voltage is connected.
- · Use the holder or a socket of a vceuai IC to keep the oxidation and charge stability in the CMOS IC.
If the CMOS IC needs to be mounted on the circuit board with direct solder then use a very small soldering iron leak and solder must be earthed. Although CMOS ICs do not have the same immunity as other ICs. A critical and worrying moment is simply removing the CMOS IC from its protective plastic foil foam and when coupling it into the circuit. After both jobs are exceeded all will run mediocre.
In IC CM CM circuit boards unused legs must be kept in certain conditions, such as ‘0’ or ‘1 ‘, but should not be left unconnected. If left unconnected, usually CMOS IC will be quickly broken.
IC is one of the electronic components that are easily damaged by heat, both heat when soldered or when the IC works. To avoid IC damage due to heat when soldered it is necessary to install the IC sockets, so that the heat affected socket legs. While to avoid IC damage due to heat when the IC works, then the IC needs to be installed (affixed) cooling plates of aluminum or copper which usually Called heatsink.
