The choose and buy memory need to pay attention to some what?

- memory chips
The most important element of a memory is samsung r25e laptop keyboard chip, the stand or fall of it for the whole memory module influence is almost decisive. Due to build memory wafer factory need to spend billions of dollars a huge sum of money, plus the production process is very precise, so the world has the ability to produce memory chip manufacturers very little, basically have: Hynix (Hynix), Samsung (eis), Qimonda (odd dream of), Micron (MeiGuang), er will reach, force crystal, promos, South Asia.
In choosing the best memory chip priority original original word chip, because these products after a wafer plant most strict inspection and test, so the most security quality. In addition, at present a lot of module manufacturers to product image unified, especially the memory chip surface's handwriting printing into their own LOGO, give consumer choose and buy some inconvenience caused. In fact, as long as it is well-known module manufacturers of products, user can rest assured the choose and buy, but don't covet is cheap and buy off-brand small factory products.

PCB -
PCB circuit board is an important part of a memory chip load, its important index layer number is how much and samsung r26 laptop keyboard wiring process. For the mainstream DDR2 memory speaking, 6 layer circuit board is the most basic configuration, a lot of high standard, high frequency products use even eight layer PCB circuit boards. Generally speaking, layer number of PCB, the more the signal anti-jamming ability is stronger, the more help to memory stability.
In addition, the PCB surface line layout is very important also, according to the international electrical learn design specification requirements, PCB surface line must use a 135 degree Angle processing, and to ensure that lead length is consistent, local should use biker wiring.

The work took gold finger
PCB lower for a row of gold plated contact, scientific name is called "golden finger", don't look down upon these glittering contact, if one of the root falls out of the ear or oxidation, it may cause some fault hidden trouble.
At present gold finger production samsung r26s laptop keyboard process has two kinds, one kind is electric plating, and the other is the chemical plating. Electric gold-plated than chemical plating gold layer thicker, can improve the abrasion resistance and anti oxidation resistance.

- capacitance/resistance
In PCB gold finger above and chip around there will be some small electronic components, they are capacitance and resistance. Say commonly, the more resistance and capacitance for signal transmission samsung r29 laptop keyboard stability is good, especially in chip next to the efficacy capacitance and the first root gold hand guide feet filter capacitance.

How to clean dust notebook computer

Notebook,samsung r610 series laptop cpu fan desktop in use after period of time, always can't avoid some dust, such as particle fell on the shell and internal. With too much dust, resulting in heat dissipation not free, this will speed up the computer hardware life. So when your machine is necessary to clean time get oneself begin a la. The following are notebook how to clean.

Cleaning screen

LCD screen always have stains and scratch. To the cleaning, please use the smooth cloth or towel. Plastic and glass cleaner contains ammonia water, may wipe gloss film, so please use from the computer store to buy computer samsung r70 series laptop cpu fan display particular detergent. Will detergent spray in fabric, then use the brush try screen.

Cleaned their keyboard

If you have an assembly brush of small vacuum cleaner, then use it to clean the dirt from the keyboard. Can use compressed air tank blow out into each key-press dust particles between.

Cleaning cooling air vents

According to different types,samsung r700 series laptop cpu fan and the vent can be located in the side of the notebook computer, back and/or bottom. These vents can make the air flow through the computer, thus make the computer to keep them cool. These vents internal accumulation content will hinder cooling process. Purchase a compressed air tank (most computer retailers provide), will vent in the dust particles blow off.

Clean the I/O port

On the back of notebook computer with a series of port.samsung r71 series laptop cpu fan In the washing cooling air vents, using compressed air exhaust all possible accumulation in these port internal and surrounding grime.
