The importance of pcb board testing?

Printed circuit boards are widely used in various electronics and technologies, making them very valuable devices. Whether it is a mobile phone, a computer or a complex machine, you will find that pcb is responsible for the function of the device. If the printed circuit board has defects or manuf... Read More

The correct posture of using nickel plating solution in PCB manufacturing​

On the PCB, nickel is used as a substrate coating for precious and base metals. PCB low-stress nickel deposits are usually plated with modified Watt nickel plating solutions and some sulfamate nickel plating solutions with additives that reduce stress. Let the professional manufacturers analyze f... Read More

Why do PCBs have a large area of copper?

PCB circuit boards can be seen everywhere in various application appliances and instruments. The reliability of the circuit board is an important guarantee to ensure the normal operation of various functions. However, on many circuit boards, we often see many of them are large areas of copper, de... Read More

PCB board OSP surface treatment process principle and introduction

Principle: An organic film is formed on the copper surface of the circuit board, which firmly protects the surface of fresh copper, and can also prevent oxidation and pollution at high temperatures. OSP film thickness is generally controlled at 0.2-0.5 microns. 1. Process flow: degreasing → water... Read More

Remember these 6 points, and say goodbye to the defects of the automotive PCB!

The automotive electronics market is the third largest application area for PCBs after computers and communications. As automobiles have gradually evolved from mechanical products in the traditional sense to become high-tech products that are intelligent, informatized, and mechatronics, electroni... Read More

After the outbreak of the new crown epidemic, PCB incoming material analysis shows the importance

The following article is from Hitachi Analytical Instruments, author Hitachi Analytical Instruments.   Since the new coronavirus pneumonia escalated into a global pandemic, the scale of the outbreak that has not been encountered for decades has disrupted our daily lives.

Why do circuit boards need to be painted

The front and back sides of the pcb circuit are basically copper layers. In the manufacture of pcb circuits, no matter whether the copper layer is selected for variable cost rate or double-digit addition and subtraction, the final result is a smooth and maintenance-free surface. Although the phys... Read More

To prevent welding porosity in PCBA production

1. Bake PCBA substrates and components that have not been used for a long time and exposed to the air may contain moisture. Bake them after a period of time or before use to prevent moisture from affecting PCBA processing. 2. Solder paste Solder paste is also very important for the processing of ... Read More

Downstream demand of PCB industry

Increased penetration of 5G and automotive electronics will bring long-term growth momentum to the PCB industry, but under the influence of the 2020 epidemic, the demand for consumer electronics and automotive PCBs will still decline, and the demand for PCBs in the 5G communications and medical f...

Common methods of circuit board maintenance

1. Appearance inspection method by observing whether the circuit board has scorched places, whether the copper plating is broken, whether there are smells on the circuit board, whether there are poor soldering places, whether the interfaces and gold fingers are black and white, etc.   2. General ... Read More

What is the difference between vector signal and RF signal source?

The signal source can provide accurate and highly stable test signals for various component and system test applications. The signal generator adds an accurate modulation function, which can help simulate the system signal and perform receiver performance testing. Both the vector signal and the R... Read More
