An integrated circuit board is a carrier for carrying integrated circuits. But it is often said that the integrated circuit board should also be brought with it. The integrated circuit board is mainly composed of silica gel, so it is generally green. Integrated circuit board (IC) adopts semiconductor manufacturing technology. Many transistors, resistors, capacitors and […]

During the use of the circuit board of medical equipment, a large current will be generated in a short time. If a large current is generated for a long time, a large amount of heat will be generated in the main line board and circuit of the equipment. Then it must be protected by a […]

When we use the flexible printed circuit board, do you know its basic structure? Do you know what it is made of? Let’s split it to give you a simple understanding of the basic structure of flexible printed circuit board. 1. copper foil substrate (Copper Film) Copper foil: basically divided into electrolytic copper and rolled […]

In recent years, low-cost PCB proofing has been a hot topic for discussion. So there are different opinions about not having to reduce the price to attract customers. From the superficial point of view, low-priced PCB proofing may not do much harm to enterprises, or even attract a large number of customers, with the help […]

First, look at the proofing requirements. Can PCBA processing manufacturers really meet: 1. Have a look at the products manufactured by PCBA manufacturers, whether they are high-grade, middle-grade or low-end, which industry they manufacture, and whether their own PCBA proofing requirements can be met by the manufacturers. Some precision processing PCBA processing, general proofing enterprises […]

I. Part of the output power control loop of the power board The key part of the output power board is the output power control circuit. In the case of layout, you should first know the characteristics of the power circuit of the part of the output power. The key parts of the output power […]

Pcb multilayer board is a kind of unique printed board, and its existence “address” is generally unique. For example, there will be pcb multilayer board in the circuit board. This kind of multilayer board can help the equipment to switch on and off various routes. It is worth mentioning that it can also have the […]

The thermal conductivity of led substrate is related to the insulation layer (usually PP, thermal grease, etc.) inside the aluminum substrate, and it is one of the three criteria to measure the quality of aluminum substrate (thermal resistance and withstand voltage are the other two properties). The thermal conductivity of aluminum substrates can be measured […]

Generally, the heat dissipation design of aluminum substrate LED is based on fluid dynamics software simulation and basic design. Resistance of fluid flow: due to the viscosity of fluid and the influence of solid boundary, the fluid is subjected to resistance in the flow process. This resistance is called flow resistance, which can be divided […]

When most hardware engineers contact PCB layout tools, PADS, Allgero, Protel and other tools from the beginning, they will inevitably contact the packaging and manufacturing of components. Whether it’s SMD components, QFP, QFN, BGA, PGA, SOT23, TO263, MOIC and other chips, or passive components such as 0402, 0603, 0805, etc., all have to touch the […]
