PCB Introduction to printed circuit boards
In this way, the printed circuit or printed circuit of the finished board called printed circuit board, also known as printed board or printed circuit board.
Understanding PCB
In order to understand PCB, it is necessary to understand the production process of usually single-sided, double-sided printed circuit board and ordinary multilayer board, in order to deepen the understanding of it.
Overview of high precision technology of printed board PCB
Buried, blind hole structure of the printed circuit board, generally use the "sub-board" production mode to complete, which means that after several times of pressing plate, drilling, hole plating and so on to complete, so precise positioning is...
PCB design for power processing and plane segmentation
In high speed PCB, RF energy is usually coupled between the power plane and the ground plane to become the edge flux leakage.
PCB, circuit board, circuit board
There are many kinds and numbers of holes and complex shapes of single-sided paper substrate and double-sided non-metallic holes of epoxy glass cloth substrate.
Brief discussion on several important technical properties of PCB ink
It is a short name for dynamicviscosity. The viscosity is generally expressed in terms of the shear stress of the fluid flow divided by the velocity gradient in the direction of the flow layer in international units of Pa/s (Pa). S) or millipa/second (mPa
Etching process of PCB outer circuit board
That is, on the copper foil part of the outer layer of the board to be retained, that is, on the graphic part of the circuit, a layer of lead tin corrosion resistance layer is pre-plated, and then the rest of the copper foil is etched away by chemical mea
What are the key points of PCB wiring for surge prevention?
General engineers only consider the design of system functionality when designing, but it is possible that the system needs surge design, and the transient surge current should reach 3KA.
Use PCB holes to reduce EMI
The PCB mounting holes help secure the PCB to the housing. But this is its physical mechanical use, in addition, in electromagnetic function, PCB mounting hole can also be used to reduce electromagnetic interference.
How to improve the appearance quality of PCB solder resistance
how to improve the appearance quality of the printed circuit board flux resistance has become an urgent problem to be solved in every PCB factory. Factors that affect the appearance quality of solder resistance
Causes of PCB deformation and damage and improvement measures
These components cannot be inserted or attached to the holes and surface pads of the circuit board and can even damage automatic cassette loaders. Welded circuit board components, bending components, feet neatly cut.
