What is a copper-based circuit board?
There are positive and negative sides, the white side is welded LED pin, the other side shows aluminum color, generally coated with thermal coagulation and thermal part contact. Ceramic substrate and so on.
The influence of wrinkle on circuit board machining
resulting in positioning (only for the large plate) or sporadic copper wire loss, but the stripping strength of copper foil near the stripping line will not be abnormal.
CMOS devices and their circuits
From here, we also know that when NMOS works, there is current flowing from the power supply (VDD) to the ground (that is, from D to S). When the power supply voltage is constant, This current follows the voltage across the gate .
4 layers of circuit board processing
it is difficult to accommodate the software used for debugging procedures, so to debug the microcontroller software, the use of microcontroller simulator.
Welding principle and welding tools
To have appropriate heating temperature, so that the solder material has a certain fluidity, can achieve the purpose of welding, but the temperature can not be too high, too high is easy to form oxide film and affect the welding quality.
What does circuit board processing open steel mesh mean
With Spectre circuit simulation platform, WillSemi maintains design integrity throughout the design cycle, increasing simulation throughput and improving productivity.
Circuit board machining inspection standard
I played once in three days and 4 times in half a month. Later, I could not help feeling "this is what the development board should have looked like".
Pcb welding principle and welding tools
The molten solder diffuses along the surface of the welds with the help of capillary suction, forming the infiltration of solder and welds, firmly bonding the components and the printing board, and has good electrical conductivity.
Circuit board processing negative
The quality of the coating is directly affected by the additive impurities and the foreign impurities brought by the electroplating process.
Hand-made PCB
The molten solder diffuses along the surface of the welds with the help of capillary suction, forming the infiltration of solder and welds, firmly bonding the components and the printing board, and has good electrical conductivity.
