The method of judging the quality of PCB circuit board
Now there are many ways to layer, there are potions corrosion, tool stripping, but it is easy to put the layer over, lost data. Experience tells us that sandpaper is the most accurate.

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
Ceramic board pcb board
the dielectric constant is small, can be used in high frequency. If applied to the electronic communication industry, it can greatly reduce the signal loss rate. The price of ordinary PCB board on the market will vary according to different materials.
Overcome the challenge of alignment of multiple connector groups between PCB boards
The procurement of certain PCB boards is controlled only by the specifications embedded in the Gerber packet. PCB boards can be built from these packets, regardless of mechanical tolerances.
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.
How to reduce PCB board space with the smallest device?
Chip-on-chip (WCSP) or core-sized ball grid arrays (DSBGA) use fine-pitch wire bonding and flip-chip interconnection, and are available in SiP, modular, stacked and recessed core-based formats.
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 printing
The progress and development of copper clad plate is also driven by the innovation and development of electronic machine products, semiconductor manufacturing technology, electronic installation technology and PCB manufacturing technology. In this case, c
From PCB to IC carrier to class carrier
In order to achieve the smaller space, faster speed, higher performance of the goal, the printed circuit board "light, thin, short, small" requirements continue to improve, PCB board structure requirements continue to improve.
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.
Common PCB board substrate analysis
The properties of the developed substrate materials are provided to the designer of the whole electronic products in time, so that the designer can establish accurate and advanced data basis.
