Along with the development of The Times, the progress of science and technology, the hard disk heads and related technology constantly updated, development, is now the biggest single disk capacity of up to 30 gb hard drive, on the market at present the mainstream of the hard disk capacity in 30 gb - too Between 40 gb. Personally think that, if you want to choose and buy computer hard disk, hard disk capacity to around 30 gb. Why such advice, mainly because now both in office software and game software, the interface is more and more glaring, its function is more complete, more and more powerful, because of this, they are also far from a few GB memory can meet, if choose not to choose a larger capacity of the hard disk, the late will be not enough. If it is a multimedia enthusiasts or producer, advised to choose a more large capacity hard disk, like 40 gb - Between 50 gb, so as to ensure adequate SMT circuit board processing memory for use. Circuit board maintenance in use, should be regular maintenance, to ensure that the circuit board to work in a good condition and reduce the failure rate - circuit board PCB SMT processing. Maintenance of the circuit board in the following several ways: 1, half maintenance: (1) every quarter to clean dust on printed circuit boards, circuit board special cleaning fluid for cleaning are available, and the circuit board after the dust cleaning, then blow dry circuit board with blower. 2 watch is there after high temperature electronic components in the circuit, electrolytic capacitors have not summoned the leakage phenomenon, should be replaced. 2, annual maintenance: (1) to clean up the dust on the circuit board. 2 to sampling observation of electrolytic capacitor capacity of circuit boards, such as found electrolytic capacitor has a capacity of less than 20% of the nominal capacity, should be replaced, generally the life of the electrolytic capacitor is ten years or so, it must be all be replaced, in order to ensure the performance of circuit board. (3) for high power devices with cooling silicon grease, should check the cooling is there dry solid silicon grease, for dry solid dry solid heat dissipation silicon grease should be cleared after coated with new heat dissipation silicon grease, in order to prevent the circuit board burn out due to bad heat dissipation of high power device.
