Grid setting skills In the PCB layout design

Posted on April 08, 2018 by G

PCB design needs to set different points in different stages. In the layout stage, large grid points can be used for device layout.

Engineers conclude: PCB design goes from shallow to deep

Posted on April 04, 2018 by G

When I saw the PCB of a computer motherboard, I thought I was able to draw a great thing myself. Later when touched protel99se and entered the drawing board team, followed by Altium, Cadence, and so on. As the experience of the drawing board accumulated, more and more issues were noticed. A good PCB board is not only connected to the line.

The definition of the circuit diagram

Posted on April 03, 2018 by G

The circuit diagram, which is a schematic diagram of the connection of the electronic components drawn by symbols of the circuit components, describes in detail the connection and direction of each component, the description of each pin, and some detection data.

PCB design should consider the hole size of the pad

Posted on March 30, 2018 by G

The pad design is designed to achieve the smallest diameter, which is at least 0.5 mm greater than the maximum diameter of the weld terminal orifice flange. The test pads must be provided for all nodes in accordance with ANSI/IPC 2221. Nodes are two or Electrical connection points between multiple components. A test pad requires a signal name (nodal signal name), the xy coordinate axis associated with the reference point of the printed circuit board, and the test pad's coordinate position (describe the test pad On which side of the printed circuit board). The information needed to provide fixtures for SMT will also need to be printed on the assembly technique of the circuit board assembly to "fix the device in the circuit test" or commonly referred to as "fixed nail bed." With the help of devices" to promote testability in the circuit. In order to achieve this purpose, you need to:

Shielding method in high-speed PCB design

Posted on March 21, 2018 by G

The transmission rate of high-speed PCB design and cabling systems is steadily accelerating, and it also brings about some kind of anti-jamming vulnerability. This is because the higher the frequency of transmitting information, the higher the sensitivity of signals, and the lower and higher the power of their signals. The wiring system at this time is more susceptible to interference. Interference is ubiquitous. Cables and equipment can interfere with other components or be severely disturbed by other sources of interference, such as: computer screens, mobile phones, motors, radio transmission equipment, data transmission, and power cables. In addition, potential eavesdroppers, cybercriminals, and hackers continue to increase because of their enormous damage and loss to UTP cable information interception.
