There are many brands of PCB assembly machines, so it is important to learn the reasons for choosing PCB assembly.Today, Alice will talk about the reasons why we chose 3 kinds of SMT machines at the beginning.
Around 2000, Alice was engaged in SMT assembly market development in TDA (an Australian company in Shenzhen, China, mainly engaged in fingerprint locks and smart home alarm products). There are two types of SMT machines in the factory: Japan’s Fuji (FUJI) And South Korea's Samsung brand, Fuji's model was XP141 at that time, the placement area of this machine was very simple, the head was very small, about the size of a palm, and 12 suction nozzles were installed, and the 12 suction nozzles were arranged in a circle , When the PCB is assembled, the sound is still very small, and the machine is very stable.
The Korean Samsung machine model is CP45, which is similar to our current JHD machine JUKI2060. The machine is cheaper than FUJI, but its reliability is not as good as that of FUJI. In one of our meetings, the SMT engineer told me that the Samsung machine lost 20% of its electronic materials. --In the real PCB industry, the loss rate of electronic components is 3 to 5 per thousand.
So when Alice went to Shenzhen Baoan District to choose a machine, the Samsung machine was ranked behind the Japanese machine, mainly because we hope the machine has high stability and durability.
Baoan District is in the west of Shenzhen, close to Shenzhen Airport, and in the suburbs of Shenzhen, so there are a large number of companies and individuals buying and selling SMT machines, but the development of the industry is not standardized, and most people will be deceived when purchasing, and I am one of them , I will write an article to tell you about this in the future.
There is another important factor in choosing an SMT machine, which is the layout of the components on your PCB. At that time, our order included small materials, as well as large MCUs and CPUs. At this time, it must be a multi-functional placement machine. FUJI's XP141 is not Multifunctional machine, at this time, I heard from the supplier that JUKI's 2060 can mount small electronic components, as well as large electronic components.
Finally, I learned that Yamaha machines in Japan also have multi-function machines. At that time, the model was YG100XG. Now in 2023, YSM10 and YSM20R are selling very well, and the procurement cycle sometimes even takes 1-2 years.
Considering that Yamaha, JUki, and Samsung are also due to budget reasons, other brands, Panasonic, Fuji, and Siemens machines are much more expensive than them.
