IT-988GSETC

The IT-988GSETC is an advanced low CTE, high Tg ( 180° C by TMA), halogen free, low Dk and ultra-low loss material. This material is especially designed for leading edge high speed applications, like the 56Gbps per channel data rates using PAM-2 or PAM-4 signaling. The product offers very stable dielectric properties and operates very well at 14 GHz and 28 GHz Nyquist frequencies required for 56Gbps+ data rates. The product is designed for enterprise applications ranging from >400 Gbps data rates into multi-channel terabit rates. The product uses low DK glass which helps with the skew related issues. The prepreg constructions are designed with spread glass and laminates offer multi-ply spread glass constructions to reduce the fiber weave effect. Due to very stable Dielectric properties, IT-988GSETC is also suitable for Radar and Antenna applications as well as hybrid and mixed mode RF & High Speed digital designs. IT-988GSETC also exhibits high thermal and CAF reliability.

What is the POFV process of PCB? Why use POFV technology?

Image
The process flow of POFV has become more and more widely used in the PCB industry in recent years, especially in some products with high layers and large board thickness, which is very popular. People hope to use resin plug holes to solve a series of problems that cannot be solved by using green oil plug holes or pressure-filled resin. However, due to the characteristics of the resin itself used in this process, many difficulties need to be overcome in manufacturing to achieve good quality resin plug products. With the continuous updating of electronic product technology, the structure and installation method of electronic chips are constantly improving and changing. Its development is basically from components with plug-in feet to highly dense integrated circuit modules using ball matrix arrangement of solder joints. You can see the development history of parts from the following figure: In the PCB industry, many process methods have been widely used in the industry, and peop...

PCB Design, Manufacturing & Assembling

In this article, you'll get to know the fundamentals of PCB manufacturers and how our company "PCBSKY" is unique from other manufacturers in China. What are the three main aspects of the PCB industry?   According to our experience of more than 10 years as the leading PCB Company in the industry, we can easily write that three main aspects in the PCB industry for which most clients look for are: PCB Design PCB Manufacturing  PCB Assembly Design, Manufacturing, and assembling of PCB is a systematic method for examining the parts and components which is needed to execute. It included obtaining costs of a commodity and seeks to cut costs before actual development begins. There are specific manufacturing, design, and assembling principles required to be following during the PCB process execution of any electrical or electronics part. Eventually, a final design concludes the series with a review among the most common issues related to the PC Board or Printed Circuit Board....
