With the rapid development of mobile phone, electronics and communication industry, it also promotes the continuous growth and rapid growth of circuit board proofing industry. People have higher and higher requirements for the number of layers, weight, precision, material, color and reliability of components. Due to the fierce price competition in the market, the cost …
Whether amateur or professional technician, to learn to build and maintain their own projects and systems, we must understand how PCB works and can repair them in case of PCB failure. So, how to repair PCB? How can I master this skill? What is the benefit of mastering this skill for your career? Why do …
The common drilling holes in PCB are through hole(VIA), blind hole and embedded hole. What’s the meaning and characteristics of these three kinds of holes? Via(Through Hole) What is Via? Via is a common hole and used to direct or connect copper foil lines between conductive patterns in different layers of the circuit board. Because PCB is formed by many copper …
The reduction of the number of PCB layers can greatly save the cost, the price difference is very wide. It can almost be said that the cost of every two additional layers of PCB will double. That is to say, the cost of four layer PCB is twice that of two layer PCB, and the …
What’s PCB Prototyping? PCB prototype refers to the trial production of printed circuit boards before mass production. It is mainly used in the process of small batch trial production to the circuit board factory after the electronic engineers have designed the circuit and finished drawing PCB. Production Process of PCB Prototyping Manufacturer Contact the manufacturerFirst, …
Fault Characteristics and Maintenance of PCB Capacitor Damage The fault caused by capacitor damage is the highest in electronic equipment, especially the damage of electrolytic capacitor is the most common. The damage of capacitance is shown as follows: the capacity becomes smaller, total loss of capacity, electric leakage and short circuit. Capacitors play different roles …
We will discuss the contents of “grounding” in PCB layout of boost DC / DC converter. It is often heard that “grounding is very important” and “grounding design needs to be strengthened”. In fact, in the PCB layout of boost DC / DC converter, the grounding design which does not fully consider the grounding and …
As an engineer, we often come across problems when we layout and route circuit board. According the experience, we summary some skills about the PCB layout and routing. Before PCB layout and routing, the layout of the components in the entire board needs to be set.The shape and size of the board must be determined …
In PCB production process, drilling is very important. The so-called drilling is to drill the required through holes on the copper clad laminate to provide electrical connection and fix devices. If there is a problem in the via process, the device can’t be fixed on the circuit board, which will affect the use or the …
In PCB design, layout is an important part. The quality of the PCB layout result will directly affect the effect of the wiring, so it can be considered that a reasonable layout is the first step to a successful PCB design. There are two layout methods, one is interactive layout, and the other is automatic …
