What Is The Difference Between Laser Welding and Reflow Welding?
Introduction to reflow oven Reflow oven uses flux coating, then preheating circuit board/activated flux, and then using welding nozzle for welding mode. The traditional artificial soldering iron welding needs to use point-to-point welding for each point of the circuit board, so there are more wel...Read more -
What Are The Advantages of SMT Processing Technology?
SMT processing process: First on the surface of printed circuit board solder coating solder paste, again with SMT machine components of metallized terminal or pin accurately on the bonding pad of solder paste, then put the PCB with components in the reflow oven whole heated to melting solder pas...Read more -
What Does a Selective Wave Soldering Machine do?
Selective Wave Soldering Machine Types 1. Mask selective wave soldering Mask selective wave soldering is a selective welding process that uses mask to expose the welding areas and cover the areas that do not need welding. It is widely used and suitable for the production of small and medium batch...Read more -
How to realize conductive hole plug hole process?
For SMT board, especially for BGA and IC pasted on the conduction requirements must level off, the plug hole convex concave plus or minus 1 mil, can not have guide hole edge on the red tin, guide hole is Tibetan beads, in order to meet customer requirements, conducting plug hole process is multif...Read more -
How to quickly estimate the resistance of PCB surface copper wire?
Copper is a common conductive metal layer on the surface of a circuit board (PCB). Before estimating the resistance of copper on a PCB, please note that the resistance of copper varies with temperature. To estimate the resistance of copper on a PCB surface, the following formula can be used. When...Read more -
What Does An SMT AOI Machine Do?
SMT AOI Machine Description AOI system is a simple optical imaging and processing system integrated with cameras, lenses, light sources, computers and other common devices. Under the illumination of the light source, the camera is used for direct imaging, and then the detection is realized by com...Read more -

What Preparations Should Be Made before Wave Soldering Machine?
The production process of wave soldering machine is a very key link in all the stages of PCBA production and manufacturing. If this step is not done well, all the previous efforts are in vain. And need to spend a lot of energy to repair, so how to control the wave soldering process? 1. Check the ...Read more -
The Importance of X-ray Inspection Machine
X-ray: Full name of X-ray testing equipment, is the use of low-energy X-ray, scan imaging of the product interior, to detect internal cracks, foreign bodies and other defects. That’s how hospitals do X-ray scans. The intelligent and miniaturization of electronic products make the size of ch...Read more -
What is solder paste inspection machine (SPI)?
I. Classification of SPI machine Solder paste inspection machine can be divided into 2D measurement and 3D measurement. 1. 2D solder paste inspection machine can only measure the height of a certain point on the solder paste, 3D SPI can measure the solder paste height of the whole pad, more can r...Read more -
Difference Between Layer 2 and 4 PCB
The basis of SMT processing is PCB, which is distinguished by the number of layers, such as 2-layer PCB and 4-layer PCB. Currently, up to 48 layers can be achieved. Technically, the number of layers has unlimited possibilities in the future. Some supercomputers have hundreds of layers. But the mo...Read more -
What Is The Difference Between Wave Soldering Machine and Manual Welding?
In the electronic industry, PCBA processing for software materials have wave soldering machine and manual welding. What are the differences between these two welding methods, what are the advantages and disadvantages? I. Welding Quality and Efficiency Are Too Low 1. Due to the application of ERSA...Read more
