The positioning of NC milling is to use the positioning pin to locate the printed board to be processed to the working table of the milling machine, so as to conveniently and accurately process the shape of the printed board.
The PCB thermal cycle temperature is summarized in Table 1 below according to the five grades classified according to the different position of the vehicle.
Circuit board negative circuit or copper surface is transparent, positive circuit or copper surface is black
With the continuous improvement of automobile safety, comfort and intelligence, PCB (printed circuit board) products are also facing the development of intelligent and green needs.
In commercial production, two laser technologies are available for PCB laser drilling. CO2 laser, UV laser. In order to meet the increasing demand for micropore productivity, many manufacturers have begun to introduce two-head laser drilling systems.
the trend of automobile electrification and electronization is more and more obvious. As the infrastructure of electronic products, PCB manufacturing is becoming increasingly important in the automotive supply chain
Special attention needs to be paid to the selection of materials to ensure stability in terms of temperature, humidity and bias in addition to electrical properties. This will lead to future restrictions on material selection and design rules.
PCB fabrication, of course, refers to the fabrication of the bare printed circuit board itself, while PCB assembly refers to placing components on the printed circuit board.
In this article, you will be able to learn how to design your own professional PCB board (including schematics, PCB layout, gerber generation and 3D models). We will provide you with the best tips and tricks, including free software that will help you imp
The size and type of embedded circuits vary by microprocessor, component, and operating system, but most importantly is the complexity of the software, whose code ranges from a few hundred bytes to several megabytes.
This presents considerable challenges for product designers. Before the new product can be used on carrier networks, the final design needs to be submitted for formal network and government approval, and if the antenna does not function properly or if the
In PCB electroplating, the chemical analysis of organic compounds and metal additives is more and more complex, and the chemical reaction process is more and more accurate.
