Why PCB designs generally control 50 ohm impedance?
In terms of PCB design, 50 ohm is also selected after comprehensive consideration. In terms of PCB wiring performance, generally low impedance is better.
Why do PCBS now have halogen requirements?
When PCB is used for hot air leveling and component welding, the board is subjected to high temperature (> 200), will also release trace amounts of hydrogen bromide。
The PCB routing density is increasing, so the PCB routing design is particularly important.
With the development of large-scale integrated circuit and super-large scale integrated circuit, the multilayer printed board (PCB) will be used more and more.
Design of PCB anti-jamming technology
The circuit working at high frequency should consider the interference between components. The general circuit should make parallel arrangement of components as far as possible to facilitate wiring;
SMD component PCB layout technology
Too low density of alkaline etching solution will aggravate side erosion, choosing etching solution with high copper concentration is very beneficial to reduce side erosion.
PCB hole without bad copper analysis
high heat dissipation devices in connection with the substrate should be able to reduce the thermal resistance between them.
Cooling tips for PCB circuit boards
To evaluate the heat dissipation capacity of PCB, it is necessary to calculate the equivalent thermal conductivity (9EQ) of the insulating substrate for PCB, which is composed of various materials with different thermal conductivity.
Ultra-fine line etching process of PCB for next generation packaging technology
Circuit board system interconnection includes chip to circuit board, PCB board interconnection and signal input/output between PCB and external devices.
Understand the difference and function of PCB welding aid layer and welding resistance layer
In the process of PCB high-speed signal circuit design and wiring, engineers need to shorten the lead between the pins of high-speed circuit devices as much as possible.
5G drive PCB volume and price rise
In the future, with the emergence of new demands for automotive electronics, data centers and artificial intelligence, PCB industry will usher in new growth points.
Uv laser processing applications in PCB industry
Each circuit layer in the multilayer circuit board is pressed together by the action of semi-cured sheet; Depending on the circuit design, some areas of the semi-cured sheet need to be cut and then pressed together.
