PCB seven surface treatment technology
The copper layer on the PCB is easily oxidized, so the resulting copper oxide layer can seriously degrade the weld quality, thereby reducing the reliability and effectiveness of the final product.

PCB circuit board conduction hole must plug hole, after all what knowledge?
In order to meet customer requirements, the pass-through hole plugging process is varied, the process is particularly long, the process control is difficult, often in hot air leveling and soldering experiment oil loss; Oil explosion after curing.
How to design PCB crystal oscillator
All the work of the digital circuit is inseparable from the clock signal. The crystal oscillator directly controls the whole system. If the crystal oscillator does not operate, the whole system will be paralyzed.
What do PCB laminated design need to pay attention to?
In terms of manufacturing cost, with the same PCB area, the cost of multilayer boards is definitely higher than that of single and double layer boards, and the more layers, the higher the cost.
How can board design enhance ESD functionality
In the design of PCB board, PCB anti-ESD design can be realized by layering, proper layout and wiring and installation. In the process of circuit board design, most design modifications can be limited to adding or subtracting components through prediction
How to quickly inspect the circuit board
With the appearance of 100 megabit bus, when the signal edge rate reaches picosecond level, the system performance depends more on the front-end design, requiring accurate timing analysis and calculation at the beginning of design. Timing analysis and sig
How does PCB copy board design meet the challenge
The arrival of the intelligent age, not only brings convenience to people's lives, but also has a profound impact on all industries, so the PCB copy board, design put forward higher requirements, professional PCB copy board companies should continue to im
Influence of slotting on EMC performance of PCB board
The generation of grooving can be summarized into the following two cases :1. Grooving caused by power/ground plane segmentation; 2.the through hole is too dense to form grooves.
In PCB design, these spacing is not considered, which may lead to design failure
There are many aspects of PCB design that need to take into account the safe spacing. It is classified into two categories: one is electrical related safety spacing and the other is non-electrical related safety spacing.
EMC specification for RF PCB design
In the actual design, the frequency, power rate and gain should be considered comprehensively to decide whether to add shielding plate.
Notes for RF circuit power supply design
Having a "noise-free" power supply is essential to optimizing system performance, although there are other factors that can degrade system performance in the actual design.
How to wire PCB design
No matter what work you are engaged in in the circuit board industry, if the circuit principle of electronic products is clear, you can improve the efficiency of functional testing and production efficiency of products. A trick takes you to understand the
