, because this can not control the length of the more easily burned copper line. 3. Connecting copper wire After stripping out the plastic protective layer outside the copper line, the next step is to reconnect the copper wires at both ends of the twisted strand. Before soldering with soldering iron, a plastic coat is set on the outside of the copper line at one end of the twisted pair of wires. The length of the plastic coat should be moderate, not too short, at least to be able to completely

Here I want to continue writing something related to the Mesh. After all, we may need to have many other requirements for it. In practical use of 3D games, low polygon models are generally used. In this way, we can have a better speed to run the game. In fact, DX provides us with such a function that allows us to control the complexity of the read Mesh.Public void WeldVertices (Microsoft.

Because COB does not have IC sealed Leadframe (Guide frame), but uses the PCB to replace, so the PCB welding mattress design Handy is very important, and fihish can only use electricity plated gold or enig (isotopes leaching gold), whether the Gold line or aluminum line, Even the latest brass lines have problems that can't be beaten up.PCB Design requirements for COB The finished surface of PC board must be electric plated gold or enig, and it is thicker than normal PC board plated gold

through the software to complete the infrared remote control.First of all, to prepare a 3.5mm headphone plug, preferably with a metal tail cover, so that the welding of the infrared tube installed in the inside, only exposing the LED part, not only beautiful can also play to protect the role of infrared emission LEDs. Unscrew the metal tailgate portion of the 3.5mm headphone plug, and you can see the exposed three weld points, from the rear to the le

3004202330-1-Wang Huiquan-1. How to weld the smd ic on the chip adapter board? Prepare tools for welding the integrated circuit of the table, such as a good soldering iron (the finer the head, the better) and solder paste. For fine pin spacing, first apply a layer of solder paste on the clean pad, and then use a clean constant temperature soldering iron to thin a layer of Solder Pad (according to observation, some transfer board has been painted for t

the diameter of the die field of the two optical fiber cables is equal to that of d1 = d2, the connection loss B = 0. 2. Causes of impact on Optical Fiber Connection loss The causes of Optical Fiber Connection loss are mainly the structural parameters of the optical fiber and the welding quality of the melting machine. There are also some human and mechanical factors, such as the bending loss of the optical fiber receiving tray, cross Section quality of Optical Fiber cutting, horizontal mismat

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.

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

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.

Environment-resistant fiber optic connectors are able to withstand harsh outdoor environments, providing the same reliability and performance as a weld network-and have the added advantage of reducing installation costs, increasing flexibility, and simplifying connectivity. Durable connector systems, made up of environment-resistant connectors and adapters, can withstand the harshest natural environments, including extreme temperatures, c

No-brand inferior mouse button failure more than the reed break, because some are plastic reed, treatment

One, the CMOS parameter is lost After booting the prompt "CMOS Battery State Low", can sometimes start, use a period of time after the crash, this phenomenon is mostly caused by insufficient CMOS power supply. For different CMOS power supply modes, different measures are taken: 1. Welding battery: Re-weld a new battery with a soldering iron. 2. Coin-cell battery: direct replacement. 3. Chip: Replace this chip preferably with the same type of chip
