Why should capacitors be placed nearby in PCB design?
The method of high-speed PCB design and wiring to solve signal crosstalk: First, in possible cases to reduce the signal along the conversion rate usually in the device, while meeting the design specifications as far as possible to choose slow devices, and
The hole cover oil of PCB circuit board and the hole open the window, silly can not be clearly separated?
This article focuses on conductive holes, keyholes, and the connection between Protel 99 SE/pads/ and CAM350 geber files Conductive holes: via keyholes: pad is particularly prone to several problems
PCB board to do the importance of plug hole
The plug technology meets the following requirements :1. Copper can be found in the through hole, but the plug cannot be used for resistance welding. 2. There must be tin lead in the through hole, with a certain thickness requirement (4 microns). Do not a
Analysis of common rule of thumb in PCB design and wiring
For you to analyze the common rules of thumb in PCB design wiring: first, vertical wiring, second, heat dissipation hole, third, right Angle wiring
Why are most PCB board colors green?
Purpose and precautions of reserved process edge in PCB design: Reserved process edge is the part added on both sides or four sides of PCB board to assist patch plug-in welding, which is mainly to assist production and does not belong to the PCB board. It
PCBA processing difference between chip components and plug-in components
PCB design layer number to consider the following problems: 1, use,2, required signal type,3, through hole type,4, required signal layer density and number,5, required plane number,6, manufacturing cost,7, delivery time,
Analysis of the deformation cause of PCB board in the process of processing
Analysis of the deformation causes of PCB board in the process of processing: 1. Incoming material of copper clad plate: 2. Pressing: 3. Welding resistance, character and other baking process: 4. Hot air solder leveling: 5. Storage
PCBA double-sided back welding process and matters needing attention
Single-side backwelding boards are rarely used now, because double-side backwelding can save space on the circuit board, which means it can make the production smaller.
PCB boards are widely used in the field of automatic testing of printed circuit boards
PCB board test system will have a new design idea, the use of automatic test system based on USB bus and virtual instrument design idea, give full play to the role of the computer
Why should PCB board use gold plating process?
new energy electric vehicles, module board, industrial control circuit board, medical circuit board, intelligent security PCB board, automotive electronic communication circuit board
Detailed the copper sinking process of PCB board production and processing
The post-process can only be screened probabilistic through destructive experiments, and it is impossible to effectively analyze and monitor a single PCB board.
