Why plug the PCB board through the hole?
After a lot of practice, the traditional aluminum plug process is changed, and white mesh is used to complete the circuit board surface welding and plug holes. Stable production and reliable quality.

PCB a reliable ground layer
These ground plane planes must be connected to the main ground plane through multiple through-holes. It should be noted that the existence of ground point will cause the inductance characteristics of the side to change, so the selection of inductance valu
Radio frequency and digital circuit design on PCB board?
This article is a summary of the author's experience in the actual development, hoping to help many RF IC developers shorten the development cycle, avoid unnecessary detours, save manpower and financial resources
Control PCB cost, these four points you want to look at
Usually the same area, the more PCB layers, the more expensive the price. The design engineer should use as few layers as possible to complete the PCB design while ensuring the quality of the design signal.
Analyze the mechanism of PCB failure or defect
scanning acoustic microscope shows its special advantage in nondestructive detection of multilayer high density PCB. And the general obvious explosion plate is only through the visual appearance can be detected.
Super - complete pcb failure analysis technology
As the carrier of various components and the hub of circuit signal transmission, PCB has become an important and key part of electronic information products. Its quality and reliability level determine the quality and reliability of the whole equipment.
PCB multilayers rarely have odd layers, why are they all even layers
At present, there are more than 100 layers of PCB, then why do people have "PCB multilayer board why are even layers?" What about this question? Relatively speaking, even layer PCB does have more than odd layer PCB.
Optical module PCB and optical device simulation overview
It should be noted that the simulation design of optical devices to photoelectric conversion (EO\OE), how to accurately reproduce this conversion process in simulation, requires some experience accumulation.
PCB impedance board impedance line design
where the capacitor in the circuit to AC current obstruction effect is called capacitive reactance, inductance in the circuit to AC current obstruction effect is called inductive reactance, capacitance and inductance in the circuit to AC current caused by
Nine rules of high speed PCB design to solve EMI problems
With the success of high-speed PCB design, the contribution to EMI has been paid more and more attention. Almost 60% EMI problems can be controlled and solved by high-speed PCB. I have done EMI design for 4 years, and I have some ideas to communicate with
Design skills and key points of PCB automatic routing
Nowadays PCB design time is getting shorter, smaller and smaller board space, higher and higher device density, extremely demanding layout rules and large size components make the designer's job more difficult.
PCB design Layout Guide for engineers
layout designers must ensure that their work is fully documented and that the final product is ready to be included in the main electronic system of their design.
