PCB circuit boards

Advantages and disadvantages of different surface treatments of PCB circuit boards

Nickel gold is a kind of surface treatment technology with large application. Remember: nickel layer is nickel phosphorus alloy layer, which is divided into high phosphorus nickel and middle phosphorus nickel according to phosphorus content.

Common impedance pcb circuit boards

Common impedance pcb circuit boardsDefinition of Impedance: In a circuit with resistance, inductance and capacitance, the hindrance to the current in the circuit is called impedance. Impedance is often represented by Z, which is a complex number. The real

How to maintain PCB circuit boards to extend the service life?

With the rise of the electronic industry, circuit board production and development has become a more and more important part of PCB proofing a circuit board is not simple, easy to say.

PCB circuit boards throw copper common three main causes

ircuit board defect detection includes two parts: solder spot defect detection and component detection. The traditional detection adopts manual detection method, which is easy to miss detection, slow detection speed, long detection time and high cost, and

What are the common surface treatment processes of PCB circuit boards

At the same time, it must be easily removed by flux quickly in the subsequent welding high temperature for welding. OSP process is simple, low cost, widely used in PCB manufacturers.

EMI design specification steps for PCB circuit boards

Experienced power developers know that EMI suppression in the PCB design process can save a lot of time for EMI suppression design in the final process to the greatest extent. This article will explain to you the specification steps in PCB EMI design, int

Five methods to improve the quality of PCB circuit boards for vehicles are recommended

Attention should be paid to the wiring of signal lines under magnetic beads, between pads and those that may come into contact with magnetic beads. Some magnetic beads conduct electricity quite well and may produce unexpected conductive paths.

Cooling tips for PCB circuit boards

To evaluate the heat dissipation capacity of PCB, it is necessary to calculate the equivalent thermal conductivity (9EQ) of the insulating substrate for PCB, which is composed of various materials with different thermal conductivity.

What are the characteristics of PCB circuit boards that are widely used?

he system speed can be greatly reduced because of the increase of delay time caused by the delay of 2ns per 30cm line length of the common interconnect on the baseboard. Image shift register synchronization counter.

Explain the storage and shelf life of PCB circuit boards

the temperature reproducibility can be obtained through multiple tests, so as to systematically evaluate the performance of the press.

Five general types of PCB circuit boards are introduced

Five general types of PCB circuit boards: single-sided circuit boards, double-sided circuit boards, multilayer circuit boards, rigid circuit boards, flexible circuit boards

Why do PCB circuit boards need to have a place to test?

Basically, the goal of setting up the test area is to test the components on the circuit board for specification and weldability.
