pcb manufacturing

  Hello, friends. Welcome to Joinwin Blog. Today we would like to talk about another product motherboard. This is also a popular product from Joinwin. Our motherboard factory is located in Longhua district, Shenzhen. The motherboard PCB is all solid state. It means it will work more stable. Besides, our chip set only use original Intel. This is the most important and expensive part of whole motherboard. Good PCB and high quality chip are the basic of whole motherboard. Secondly, most of our CPU socket covers are from Foxconn. You can see this Foxconn logo. Because in our experience, customers like Foxconn quality a lot. Although Foxconn covers actually expensive a little, we will also choose them. In the production, we will have three times QC. If you buy our motherboard, you can see QC label on the back side of PCB. According to that QC label, if have defective parts, we will easily to know which worker was responsible of it. From this...

  Dear Friends,welcome to Joinwin Blog. To make our customers aware of the high quality of our products, today I will show you the process of producing ram memory module in our factory. Our production line includes 5 main steps.The first step is SolderPaste, we put the prepared ram pcb boar d on this machine,The machine will automatically scrape paste on where the chip needs to be soldered. Picture as follow. Then we goes to the second step:SMT:Surface Mount Technology. That is waht we called SMT. This machine will attach components, such as original DRAM chips and SPD chips, to the PCB surface. These procedures will all completed by this high-speed SMT machine. And by the way,we use Yamaha brand SMT machine, which is of high speed and high functions After SMT, the chip components that have been attached to the PCB are still not completely fixed. Therefore,we come to the third step:Reflow soldering. it is necessary to enter the reflow soldering ...
