Flexible circuit board (FPC) is a kind of flexible printed circuit board which is made of polyimide or polyester film with high reliability and excellent flexibility.FPC is also known as soft circuit board and flexible circuit board. It is favored for its light weight, thin thickness, free bending and folding. FPC is a technology developed […]

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 […]

Simply put, reflow soldering actually means that there is a heating power supply circuit in the soldering furnace, which heats the gas or N2 to a sufficiently high temperature and blows it to the pcb board where the components have already been pasted, so that the solder on both sides of the components can be […]

Flexible circuit board features: (1)FPC is small in size and light in weight.   (2)FPC can be moved, bent and twisted.   (3)FPC has excellent electrical properties, dielectric properties and heat resistance.   (4)FPC has high assembly reliability and operability.   (5)FPC can be installed with three-position connection.   (6)FPC is beneficial to heat diffusion.

Nowadays, the factors considered in pcb design are more and more complicated, such as clock, crosstalk, impedance, inspection, manufacturing and processing technology, which often urges the design staff to repeatedly carry out a lot of reasonable layout, certification, maintenance and other work. On-line editor of main parameter bundle can compile this main parameter into formula […]

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 […]

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 […]
