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 -
