The advantages of HDI in PCB circuits

pcb printed circuit boards


With the increasing demand for the advanced devices and, HDI (High-Density Interconnects) is concept widely applied in the pcb printed circuit boards. And now, HDI technology is incorporated into the basic fabrication of the PCB itself and the connections to the components. With such interconnects, what can it bring for us? Let us talk about the advantages of the HDI in PCB circuits.


The obvious advantage is that HDI technology can guarantee the smaller size and lighter weight, which means that the pcb circuit boards fit into smaller spaces and have less mass than conventional printed circuit designs. The smaller size and weight also contributes to less chance of damage from mechanical shocks.


Secondly, HDI benefits signal integrity in the pcb circuit boards. With new electronic components such as ball grid arrays and chip-scale packaging achieving widespread use, designers are creating PCBs with new fabrication technologies to accommodate parts with very fine pitches and small geometries. At the same time, clock speeds and signal bandwidths are becoming increasingly fast, and this is challenging system designers to reduce the effect of RFI and EMI on the performance of their products. Moreover, the constant demand for denser, smaller, faster, and lighter systems are compounding the problems with restrictions placed on cost targets.


And usually, HDI circuits adopt the microvias for its high density, which offering ten times lower parasitic influence of through hole design. This can ensure that the HDI circuits can meet the stringent RFI/EMI requirements, and maintaining HDI circuit signal integrity at the same time.

How to CPU in a dual processor motherboard?

One question we get asked at least one time each week is whether or dual socket motherboards meant for dual processors can work with one CPU. A common driver behind this question is because dual processor motherboards allow for easy expansion at a later date. Add a second CPU, heatsink/ fan and additional memory to a system without replacing any internal components or adding a second machine. The answer to the question “Can I use one CPU in a dual processor motherboard?” is yes… with some caveats. Let’s explore why. The vast majority of motherboards “just work” if you install a CPU into the lowest numbered CPU slot. This is usually CPU0 if there is CPU0 and CPU1 or CPU1 if the board is tagged CPU1 and CPU2. This is true for both Intel and AMD motherboards in general and when in doubt, most motherboard manuals will instruct a user as to which processor slot can be populated by a single CPU and a dual CPU motherboard. Here is an example from an ATX X79DUAL motherboard tha...

  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...

  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...
