What Is H3B Industrial Managed Switch? Network Switch connects different equipment by packet switching to forward and receive. It processes data from one device to another ending device with certain speed and transmission rates. Managed switch targets on the data transmission to a specific device instead of transmitting to all ports on the devices. It allows you to configure and gives priority on certain ports. They can also allow you to monitor the network traffic on certain LAN ports and control certain access according to your needs. H3B offers a wide range of engineered manageable industrial switches to ensure reliable performance in all kinds of harsh industrial environments. H3B Industrial Managed Ethernet Switch are with extraordinary performance with different copper/fiber connectors to support high bandwidth applications demands. On the basis of unmanaged models, it offers the possibility to establish a customized and smart network according to the deployment requirements. How Does H3B Industrial Managed Ethernet Switch Work? H3B managed Ethernet switches offer a reliable way for our customers to build and expand their industrial network quickly and efficiently. H3B managed Industrial Ethernet switches provide fast Ethernet, gigabit and 10G combo ports as well as all kinds of network protocols, such as SNMP, Web-management, and Ethernet/IP, etc. Besides those, we offer devices with advanced Ethernet management features including VLAN, IGMP Snooping, QoS, trunking and port- mirroring. With the help of those management functions, our managed series device is the ideal solution for numerous industrial network deployments. All H3B managed industrial switches come with detailed configuration manuals. In application scenarios that require management functions, it will do great help. Except for quality control, we’ve also put great effort into the service. With the development, we will release more high-quality and price- competitive managed industrial switches in the near future.Our major products including industrial ethernet hub, fast fiber converter, Fiber switch, PoE switch, and industrial fiber switch, etc. We always persevere in innovation and creating new technologies, make sure of all the products are more advanced than our competitor. 80%of our products are exported to more than 180 countries etc.RFQ today. It will be a great choice to choose H3B. Looking forward to win-win with all of you together.RFQ today.

In general, in a 4 layer pcb prototype , both the top and bottom layers belong to the signal layer, while another two inner layers are GND and VCC. If the first inner layer has several GND planes, the blank areas of which should be filled with copper. It could also have some routings, but do remember these routings are not allowed to cross the copper area. Same to the second layer with several powers. Usually, layers of a 4 layer PCB are connected by plated through holes, buried holes, and blind holes while layers of a 2 layer PCB are only connected by plated through holes. Besides, if possible, VCC and GND should not serve as signal layers. There are insulation materials between the two layers. After every layer is printed with circuits, we could use lamination to make circuits overlap and use drills to make via holes to connect circuits. Since a 4 layer, PCB has routings in several layers, it is a good choice if you want to design elaborate products in small sizes, like mobile phone circuit boards, mini-projectors, and recorders. In addition, multi-layers provide broader space for design, control differential characteristic and single-ended impedance, and better the output of signal frequency. Right now, our electronic devices continue to pursue higher speed, larger capacity, and smaller size. Therefore, 4 layer PCB is a product that emerges as the times require. Later plated through holes, buried holes and blind holes come into being to meet people’s needs to produce circuit boards with greater density, precision. Now that computer and aerospace industries are in great need of high-speed circuits, they are asking for components with higher packaging density. Besides, discrete components are getting smaller, microelectronics is facing rapid development, and electronic devices are turning into smaller and lighter ones. With such background, the single-sided or double-sided printed boards are not capable to increase the packaging density because they have restrictions brought up by limited space.
