What Should Be Paid Attention To In SMT Patch Processing BGA
Pay attention to the moisture-proof treatment of BGA, and pay attention to details during installation and soldering.
PCB Circuit Board Open, Short Circuit Causes And Improvement Methods
Designers using this approach can focus on masking the microstrip length of the copper foil in order to obtain good performance for signal integrity. For systems that use dense connectors in the communication structure, the designer can use a PCB as the t
High Frequency PCB Interference Problems And Solutions
In the high-frequency circuit, the noise of the power supply has an obvious effect on the high-frequency signal. Therefore, the first requirement is that the power supply is low noise.
PCB circuit board production process
The OC48 interface card contains several typical mixed-signal PCB layout and routing problems, the layout and routing process will indicate the sequence and steps to solve the mixed-signal PCB layout solution.
PCB circuit board welding technology
As a power supply product, PCB circuit boards can be seen everywhere in life. This requires manufacturers to strictly put the quality in production, understand all the failure of the product, deal with it early, and reduce economic losses.
How to choose the base material of PCB board
PCB circuit board with insulation board as the base material, cut into a certain size, it is accompanied by at least one conductive graphic, and cloth holes (such as component holes, fastening holes, metallization holes, etc.), used to replace the chassis
Analysis of etching technology of PCB outer circuit board
Further said, sulfuric acid-hydrogen peroxide, can not be used for lead tin corrosion resistance layer etching, and this process is not the main method in the production of PCB outer layer, so most people rarely ask.
Analysis of anti-interference prevention methods of PCB circuit boards
The level of viscosity is of great concern to the smoothness or not of screen printing. Therefore, in the PCB ink technical documents and QC reports, the viscosity is clearly marked, indicating under what conditions, what type of viscosity testing equipme
Modularity and system integration technology
The main reason for not shining is that the electrical circuit is open, and the reason for flickering is because the gold wire is virtual welding or poor contact.
PCB transfer mechanism and bearing organization
PCB transmission mechanism and bearing organization, drive and servo positioning system, mounting head, feeder, optical identification system, sensor and computer control system, through some functions such as suction - displacement - positioning - placem
Five disassembly methods for servicing integrated circuits
Look at the PCB to see if there is scratch where the patch element falls off. Scratch where the PCB patch element falls off will also make the adhesion of the green oil insufficient, which can cause the patch element to fall after the PCB has passed the t
