Flat package, the Chinese meaning is plastic flat-pack. Chips packaged with this technology also have to use SMD technology to weld the chip to the motherboard. SMD-mounted chips do not have to be punched on the motherboard, generally on the motherboard surface has a design of the corresponding pin pads. The chip can be welded to the motherboard by aligning the pins to the corresponding pads. In this way the chip is welded, if not the use of special

0x00 What is ArduinoArduino is actually a development board, the microcontroller and the necessary components integrated into a circuit board, expand the perfect interface and pins, you can connect a variety of sensors, complete the design of your mind, you can also understand it as an electronic building block, because it does not need to weld, Also does not need the advanced radio knowledge, only needs the programming foundation and the basic circui

There seems to be only: Samsung S4., Nubian Daniel, Huawei Glory 3 and several new machines have infrared remote control function, then we use the phone does not have this function how to do? Don't worry I have a way hehe, this time DIY material easy to find and simple, we can try it yourself! DIY Material: Infrared diode 2 (no can be removed on the old remote control), 3.5 headphone plug a Production method: such as (I hard to do the figure do not steal Oh, give a praise!) ) DIY start: Two

the tube to the CPU power to adjust the role. Follow the line down and found the HIP6018BCB this small integration block, if it burns short circuit so cet ceb6030l is bound to fever. With a soldering iron and a tin-absorbing device to scrap the Dickens the integration block to be removed, and then the motherboard power to find the motherboard can be on the power, CET ceb6030l also not hot, it seems that HIP6018BCB this integration block really bad. Bought a piece of the same type of scrap boar

Common failure One: unable to find the mouse 1. The mouse is completely damaged and needs to be replaced with a new mouse. 2. Mouse and host connected serial port or PS/2 mouth contact is bad, carefully connect the line, restart can be. 3. The serial port or PS/2 port on the motherboard is damaged, this situation is very rare, if this is the case, have to replace a motherboard or use the serial port on multi-function card. 4. Poor contact with the mouse line, this situation is the most commo

likely to be faulted. (5) memory chip RAM failure The PC has more memory chips, higher utilization rate and higher failure rate of the chip itself. The (6) Data bus failure The CPU, memory, I/O device data bus, bus buffer registers/drives, and so on in the motherboard also have varying degrees of failure. The (7) Address bus Select、read fault is displayed in the address bus, address latch, and address buffer registers/drives of the CPU routing address on the motherboard. The (8) M

minutes to show up.This is caused by the leakage of the image tube seat and the tube seat must be replaced. The rear cover can be opened to see a small circuit board at the end of the image tube, and the tube seat is welded on the circuit board.On Carefully unplug the circuit board, then weld the tube seat, buy the same seat in the electronics store, and then weld the tube seat back to the circuit board. A

, even in humid weather, there will be no more "problems". 　　Second, the computer after the boot, the monitor only to hear the sound of its paintings, dark One. It takes a few 10 minutes to wait for the screen to appear. This is not the display inside damp, but the image of the tube seat leakage caused by the need to replace the tube seat. The method is: the rear cover can be opened to see a small circuit board at the end of the image tube, the tube seat is welded on the circuit board. Careful

1. Disassembly U disk package does not adopt a general screw fastening method, its key ring end using screws directly into the way, the exposed part is smooth surface, cannot use the common tool to unscrew the screw, therefore may use the small one word screwdriver to pry down the ring, or uses the method which the sharp nose pliers hard to unscrew the screw, but this way will tighten screws to twist the flower, Affect beautiful, as long as the two fixed screws down, and then the logo printed o

board. 2. Welding MINI USB Interface on the circuit board welding a total of six solder joints, four USB data connection, two floor fixed. The main reason is that the mini floor of the fixed point of welding is not tight, loose after the mini connector is directly pushed into the resulting. Welding Needless to say, as long as the original position of welding on the line, the two sides of the grounding point is easy to weld, but four data line cont

one. This kind of welding foot is unable to distinguish by the naked eye, also is not we use the brand or the wind gun to be able to weld, must under the high magnification magnifying glass, will weld the foot to use the specialized equipment to carry on the hot pressing. Some of the auxiliary materials used in this process, such as ACF and ACF, are very expensive, and the cleanliness of the operating envi

Common fault One: the computer just opened the screen of the monitor jitter very badly, sometimes even the icon and text can not see clearly, but after one or two minutes will return to normal. This phenomenon occurs more in humid weather, is the cause of damp inside the monitor. To completely solve this problem, you can use the moisture-proof sand in food packaging with cotton thread string, and then open the rear cover of the monitor, the moisture-proof sand hanging in the image of the tube n

Preparation Tools You need: soldering iron and welding material, an extra USB cable, scissor clamp and stripping pliers, small one-word screwdriver, magnifying glass Note (note) Using a screwdriver, carefully open the U disk shell. Use a magnifying glass to observe the circuit board and the welded disc. If a PCB is found to be damaged or the solder plate is detached, you may need to seek professional help. Place the U disk on a hard plane with the interfac

normal. This phenomenon occurs more in humid weather, is the cause of damp inside the monitor. To completely solve this problem, you can use the moisture-proof sand in food packaging with cotton thread string, and then open the rear cover of the monitor, the moisture-proof sand hanging in the image of the tube neck near the tube seat. In this way, even in humid weather, there will be no more "problems". Second, the computer after the boot, the monitor only to hear the sound of its paintings,

The problem of optical fiber to indoor outdoor layout has been the focus of attention in the industry, in the use of more buried layout way to build FTTH, it is necessary to comprehensively measure cost, flexibility, performance, accessibility, environmental interference and temperature difference adaptability and other indicators. At present, the outdoor part of the optical fiber to the household network system the two most common ways to create access points when connecting buried branch cabl

Whether it is NV or ATI GPU, its chips are installed on the circuit board, we call this circuit board as a GPU substrate. In the chip around a lot of SMD components (resistors, capacitors, etc.), the ends of these SMD components are silver tin compound (easy to weld with the substrate), the graphics card Factory at the base plate four weeks placed a layer of elastic latex pads. 　　The effect of this latex pad is as follows: two. 1. To prevent the ins

block really bad. It cost 15 yuan to buy a piece of sl-65fv of the Shuo Tai gram. Remove the HIP6018BCB on the scrap board to weld the motherboard to a friend, connect the load, and then power on the motherboard, and the power led on the diagnostic card shows that everything is OK. Normal voltage measurement, loaded with the CPU and memory with an excited mood press the power switch, "diagnostic card" on the number of digital tube began to beat, fro

Fault Type one: interface problem Failure phenomenon: 1, on the boot prompt "keyboard error or no keyboard present"; 2, after the boot Windows started to Blue sky and white clouds when the crash. The cause of the first failure is that the keyboard is not plugged in, the pins in the keyboard interface are bent, and the keyboard or motherboard interface is damaged. Processing: Notice whether the three lights in the upper right corner of the keyboard blink when you turn on the boot if there is
