BGA is a surface mount component that is used for chip design ICs. The full name of BGA is ball grid array. Therefore, it has many balls in the form of an array. Generally, BGA is used for chip design PCBs such as microprocessors and integrated ICs
Surface mount technology is a method of assembling electronic components onto a printed circuit board (PCB). Unlike traditional through-hole technology, where the leads of the component are inserted through holes in the PCB, SMT involves mounting the component directly onto the surface of the PCB. SMT offers advantages such as smaller size, higher manufacturing efficiency, and compatibility with automated assembly processes.
Aluminum PCB, or Aluminium PCB, also called Alu PCB, is one of Insulated Metal Substrate (IMS) PCBs, and is also one of the most commonly used Metal Core PCBs nowadays
PCB manufacturing relies on standardized guidelines to ensure consistent quality and reliability across various applications. The following list covers the most widely recognized standards from the IPC, EIA, and JEDEC organizations, essential for quality assurance in PCB design, assembly, and testing.
It is generally recommended to use the method of automatic routing + manual adjustment. Automatic routing requires routing in the order of ground line – power line – clock line – others. Set the routing priority in the routing rules, 0 is the lowest level, 100 is the highest level, and there are 101 situations in total. In more complex circuit boards, considering the requirements of electrical characteristics, interference and other factors, we all use manual routing. It is forbidden to place vias on the pins of components, and the already routed lines should be locked before automatic routing. The routing should take into account both aesthetics and electrical characteristics. In particular, the routing that affects the appearance should be routed on the reverse side. In principle, do not route the front side of the product name, model and Zhongyou logo (except in special cases), and do not allow front routing between the silk screen frame and the Keepout frame (except in special cases).
The electronics industry has undergone many changes over the past few years. Nowadays, millimeter wave radar and millimeter wave communication frequently appear in our sight. In particular, Huawei has made remarkable achievements in 5G, and millimeter wave technology has been put on the table. Why does millimeter wave technology play such a key role in 5G and smart cars? Next, let’s take a closer look at the past and present of millimeter wave technology and its continuation.
