Problem description The printed circuit board divides the wiring area into n × m squares, as shown in. Accurate Circuit Wiring problems require determining the shortest Wiring Scheme connecting the midpoint of Square A to the midpoint of square B. During cabling, the circuit can only be routed along a straight line or right angle, as shown in B. To avoid line int

For the way the company wiring, we have recently summed up the approach based on the experience of several experts, hoping to help you. Method/Step 1, determine the number and location of information points, the number and location of information points to be considered from the future application, the future office or workshop, personnel work place, should use the nearest principle, and in the wiring or

Simon's 10G 6ATM F/UTP series products meet and exceed the 10GB/S Gigabit Ethernet application standard, including its stringent external performance requirements. The world's leading network cabling solutions provider Simon proudly announces the launch of the all-new 10G 6ATM F/UTP end to end Shield Enhancement 6-class cabling solution. The 10G 6ATM F/UTP cabling system meets and exceeds all requirements for the channel in the IEEE 802.3an (Gigabit Ethernet standard based on copper cables, whi

installing PCI-E graphics card, PCI-E graphics card interface see PCI-E interface for graphics card On the motherboard of the earlier chipset, because PCI-E is not supported, it is still the traditional AGP 8x graphics interface, see the middle brown slot. The rest are PCI slots used to expand PCI devices. The back of the new Motherboard chipset does not provide com interfaces. Therefore, a com slot is built into the motherboard. You can extend the support for com to make it easier for old u

Nor flash features in-chip execution (xip, execute in place), so that applications can run directly in flash memory without having to read the code into system Ram. Nor transmission efficiency is very high, in 1 ~ The small size of 4 MB has high cost efficiency, but the low write and erase speeds greatly affect its performance. The address line and data line of nor Flash are separated. Am29lv160db is a 2 Mbyte nor flash with the partition structure: 1 16kbyte sector, 2 8kbyte sectors, 1 32kby

Notice on wiring: Features of leather Cable Leather cable is commonly known as Indoor Hanging optical cable, leather cable learning name: Access Network with butterfly introduced optical cable; because of its shape is Butterfly Shape; so some people are called butterfly-shaped optical cable, 8-word optical cable. But the leather cable is mostly single-core, dual-core structure, can also be made into a four-core structure, the cross section is 8 shape

When we conduct PCB cabling, we always face two or three kinds of situations on one board. The silly practice is of course, regardless of the case of November 21, copper is applied as long as it is the ground. This is not a problem for low-speed boards or boards that are insensitive to interference. Otherwise, the Boards may not work properly. Of course, if there are many places on a board, even if the Board has no requirements, but from a rigorous and serious point of view, we still need to use

Many enterprises, factories and other customers have been using the inverter power after buying it back, and will not perform maintenance on the power without using the inverter power supply, maintenance and so on, because doing so will lead to the short service life of the inverter power supply, how can we avoid these problems?Yes, it is regular maintenance of the power supply, so that problems can be found in a timely manner.The three-phase 10kva Frequency Conversion Power Supply consists of t

In the past year, cat5e and cat6 cable systems have gradually become the mainstream of integrated wiring. People are increasingly concerned about the on-site testing standards and how to authenticate these advanced cable systems. The following is a brief introduction to the situation. I. certification test and verification test First, we need to figure out what is the verification test and certification test of the cable system. The verification test

loss and transmission errors. Therefore, crosstalk is undoubtedly the most powerful natural enemy for integrated wiring. The difference between CAT1, CAT3, CAT5, CAT5E, CAT6, CAT6A, and CAT7 is that the copper wire diameter is getting thicker and thicker, the torque is getting smaller and smaller, the twist of the two cables is getting tighter and the gap between the line pairs more and more cross skeleton, aluminum foil, pull, streamline, copper wir

The construction owner and technical personnel should be familiar with network construction requirements, construction methods, and material usage, and be able to explain network construction requirements, construction methods, and material usage to the construction personnel, in addition, it is necessary to regularly conduct construction on the construction site, check the quality, and solve the problems raised by the on-site construction personnel at any time. 1. clarify requirements and meth
