PCB circuit board how to distinguish good and bad and detailed PCB copy board process

the general double panel copying board is much simpler than the multi-layer copying board, multi-layer copying board is prone to inaccurate situation, So the multilayer board copy board to be particularly careful and careful (which internal through holes

The four elements of characteristic impedance are developed in the manufacture of pcb circuit boards

Although the miniaturization trend makes it more challenging, it is possible to use multiple connector groups on two PCB boards by using best design practices.

PCB circuit board processing and production difficulty in where?

The high-rise plate is thicker, heavier and larger than the conventional multilayer plate. The corresponding heat capacity is also larger. When welding, more heat is needed and the welding high temperature time is longer.

PCB A balanced laminated design of printed circuit boards

In the core structure, all the conductive layers in the circuit board are coated on the core material; In the foil-coated structure, only the internal conductive layer of the circuit board is applied to the core material, and the external conductive layer

PCB board factory, design high frequency impedance circuit board what are the special methods

If the transmission line is isotropic, there will always be a current as long as the signal is transmitted.

Circuit board design: PCB size and shape requirements

With the 3D capabilities of the layout tool, designers can interactively handle their component placement in real time and correct all clearance errors in the design's mechanical features.

That is to say, in a specific storage environment, the quality of the goods must be able to continue to meet the requirements of the specification, and ensure that in the way of use, not because of storage time is too long and failure situation, this can

Blind buried through hole circuit board (HDI circuit board) PCB manufacturing three key

HDI board is one of the most precise PCB board, and its process is also more complex. The core steps include the formation of high precision printed circuit, the processing of micro through hole, the plating of surface and hole.

general solid insulation material is not easy to fill the dead corners, and where the need to be closely matched, such as high-voltage cables, transformers, small capacitors, can be filled with mineral oil, ethylene glycol and carbon chloride, as liquid i

There are several processes of sun block welding for PCB circuit boards

Sunblock welding process can be roughly divided into three operating procedures:The first step is exposure. The second step is developing. The third operation process repair board.
