IT-88GMW-3.15 Datasheet

IT-88GMW-3.15 is an advanced ultra-low loss & high Tg (185° C by TMA) material for demanding Radio frequency applications. The material is designed for long range, short range and medium range Radars used for Autonomous driving or Advanced driver assist systems operating in the 76-81 GHz. frequency range. The product offers better dissipation factor and insertion loss than fiber reinforced PTFE products. Its higher elastic modulus helps reduce mismatch in hybrid applications. The thermal conductivity is higher than PTFE based systems and therefore the product is also suitable for demanding 5G Base stations, power amplifiers and antenna applications which are expected to operate in the mm wave range of frequencies and also require high power handling capability. The product can be paired with a full prepreg offering to build high reliability multilayer boards. The dielectric properties are very stable with temperature and therefore very suitable for thermal cycling requirements in the automotive segment. The product matches the CTE of copper in X and Y planes thereby reducing stress during packaging and subsequent thermal cycling.

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.
