1. Single-sided flexible board Lowest cost. When the requirements for electrical performance are not high and single-sided wiring is possible, the single-sided flexible circuit board should be selected. This most common form has been used in commercial applications, such as ink cartridges of printers and memories of computers. The single-sided flexible board has a layer […]

Multilayer circuit boards are usually defined as 10-20 or more advanced multilayer circuit boards, which are more difficult to process than traditional multilayer circuit boards and require high quality and reliability. Mainly used in communication equipment, high-end servers, medical electronics, aviation, industrial control, military and other fields. In recent years, the market demand of high-rise […]

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 […]

What are the common problems in PCB proofing design? Do you know that?/You know what? Here’s a brief introduction from Shenzhen PCB proofing manufacturers! 1. Stacking of PCB proofing pads 1. The stacking of bonding pads (except external bonding pads) means the stacking of holes, which will break the drill bit and damage the holes […]

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 […]
