Board factory industrial PCB board maintenance needs to have what skills?
The industrial pcb circuit board belongs to the industrial control industry, mainly the PCB mother board used in industrial applications, its structure usually has many card slots, a large area, a higher degree of modularity, can adapt to a wide range of
Best practices for capturing circuit board schematics
Not only will you save money and move faster, but you'll also help you say "no" to tempting foods that may not be part of your diet. Preparing such written plans can help any project we are involved in. In the electronic field, these plans are c...
How does PCB design avoid crosstalk
Cost = materials + labor + manufacturing expenses, which materials include? Including raw material control, water and electricity control, scrap rate control, process control.
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.
