  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 ...

  Dear Friends,welcome to Joinwin Blog. Here to share with you a story about the OEM service. RMEM COMPUTER OUTLET is a Philippines company. We start the connection with RMEM COMPUTER OUTLET at the GS Fair in April 2018. In November of the same year, they proposed to customize their own label with brand logo. Combined the size of computers RAM memory module products and brand style, our designers provided three design options, and they finally chose one of them. The label is simple and bright. White color as the bottom color,retain the unique orange of the logo,change the other of the logo in to blue,layout of the basic information. Labels make the products have the brand recognition and remind the function.  As the product is labeled, it injects brand awareness into the product, and the efficiency of dealing with problems has also been improved. RMEM COMPUTER OUTLET is satisfied with our OEM RAM service . We sincerely invite you to OEM y...

  How to produce a Ram Memory? Today we will take you to learn that how a Memory be produced. There are mainly three parts, in following we will separate this process into 12 steps for your easy understand! 1. Preparing: Joinwincomputer factory workers will prepare Ram PCB and IC (solder bump already attached on IC), these PCB and IC are quality and well tested. (we are mainly using major chips from Samsung/ Hynix/ SkHynix/ Micron/ Nanya) All IC will be separated and sorted in different plate according to their band and model. 2. Tin paste soldering: This is the first step of Ram production, workers using a pneumatic dispensing device, apply the solder paste to the PCB board. The role of solder paste is to prepares the chips for the next SMT step on the PCB board. The solder paste machine will automatically scrape the solder paste where the chip needs to be welded. 3. AOI testing: After paste soldering, PCB board will pass through...

 Dear Friends,welcome to Joinwin Blog. Today, let’s talk about the new trend of doing foreign trade ---live streaming. Because of Covid-19,many fairs have been forbidden in Chna for the last 2 years. During this time, we don’t have any chance to meet our customers face to face.But with the development of e-commerce,here comes out a new industry for doing business---Live Streaming. The above pictures may show you the live streaming we have done before.In the last 2 years, we have presented 4 live shows online.on which we present our main products: SSD Internal Solid State Drives , RAM Memory Modules , and computer motherboard , as well as our ram and motherboard factories. More specifically,we showed how to produce a pieces of ram and motherboard on the live streaming. I believe our watcher are fully aware of how our factory runs after watching our live streaming,which is our main purpose to do a live show. According to the live streaming,we also get the chance to ...

  Hello, friends. Welcome to Joinwin Blog. Today we would like to talk about a hot FAQ from our customers. As you known, Joinwin provide life time warranty about ram memory. We are very confident about our ram quality. We always said we use original 3 RD chips. Quality is one thing we never compromise. So, many friends will ask us, how do you guarantee that? How do you test the ram? Do not worry. In our ram manufacture, we will have three times QC. After finishing manufacture, we will have appearance inspection. This is the first time QC. Then after PCB board cutting and information input, we will have a second QC. Here I would like share you a equipment list about our daily testing of ram memory.  DDR2,DDR3,DDR4 RAM modules Is it great? I think through this testing equipment list, you will have a better understanding about Joinwin ram testing. After testing on motherboard, we will do cleaning, spot testing before delivery. This is the final QC.Then we ship bea...

  Hi Friends, Welcome to Joinwin Blog. Today we are going to share about our SSD new design box package! So far, we have two different types of package for SSD, plastic package and color box package.
