To prolong the life of devices and prevent failures, effective heat transfer management is very important. Overheating conditions on the board can not only speed up the failure mechanism, but also cause the device to become too hot to handle and in some c
There is no doubt that condensation will severely test the insulation resistance of the coating. There are many coating products that can withstand this kind of test, so you can avoid these problems by choosing the right materials at the beginning of the
its melting point is much higher than that of the tin solder, which results in the reduction of the weldability of the surface of the welding pad, and the non-wetting of the welding pad and the solder climbing to the welding end of the device are easy to
Power integrity directly affects the signal integrity of the final PCB board. Power supply integrity and signal integrity are closely related, and in many cases, the main cause of signal distortion is the power system.
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.
