Anti-deformation installation of printed circuit board components
1. In the reinforcement frame and PCBA installation, PCBA and chassis installation process, the warped PCBA or warped reinforcement frame implementation of direct or forced installation and PCBA installation in the deformed chassis. Installation stress causes damage and breakage of component lead...Read more -
PCBA Processing Pads Are Not on The Tin Reason Analysis
PCBA processing is also known as chip processing, more upper layer is called SMT processing, SMT processing, including SMD, DIP plug-in, post-solder test and other processes, the title of the pads are not on the tin is mainly in the SMD processing link, a paste full of various components of the b...Read more -
What knowledge is needed to design PCB boards?
1. Preparation Including the preparation of component libraries and schematics. Before the PCB design, first prepare the schematic SCH component library and PCB component package library. PCB component package library is best established by engineers based on the standard size information of the ...Read more -
PCB Layout Design Considerations
In order to facilitate production, PCB stitching generally need to design Mark point, V-slot, process edge. I. The shape of the spelling plate 1. The outer frame of the PCB splicing board (clamping edge) should be closed-loop design to ensure that the PCB splicing board will not be deformed after...Read more -
What is the classification of Smt mounter placement head?
Mounting head is also called as suction nozzle, it is the most complex and core part of the program application and components on the mounting machine. If compared to a person, it is equivalent to a human hand. Because in the placement processing components placed on the PCB board action is neede...Read more -
How to Avoid The Error of Pick and Place Machine?
Automatic pick and place machine is a very precise automatic production equipment. The way to prolong the service life of automatic SMT machine is to maintain the automatic pick and place machine strictly and have the corresponding operating procedures and related requirements for the automatic p...Read more -
What Are The Important PCB Routing Rules That Should be Followed When Using High-speed Converters?
Should the AGND and DGND ground layers be separated? The simple answer is that it depends on the situation, and the detailed answer is that they are usually not separated. Because in most cases, separating the ground layer will only increase the inductance of the return current, which brings more...Read more -
What Are The 6 Key Steps in Chip Manufacturing?
In 2020, more than a trillion chips were produced worldwide, which equates to 130 chips owned and used by each person on the planet. Yet even so, the recent chip shortage continues to show that this number has not yet reached its upper limit. Although chips can already be produced on such a large...Read more -
What Is HDI Circuit Board?
I. What is HDI board? HDI board (High Density Interconnector), that is, high-density interconnect board, is the use of micro-blind buried hole technology, a circuit board with a relatively high density of line distribution. HDI board has an inner line and outer line, and then the use of drilling,...Read more -
MOSFET Device Selection of The 3 Major Rules
MOSFET device selection to consider all aspects of factors, from small to choose N-type or P-type, package type, large to MOSFET voltage, on-resistance, etc., different application requirements vary. The following article summarizes the MOSFET device selection of the 3 major rules, I believe that...Read more -
How To Transport and Store PCBA?
In order to ensure the quality of PCBA, each processing link of PCBA placement and plug-in function test must be strictly controlled, and the transportation and storage of PCBA is no exception, because in the process of transportation and storage, if the protection is not proper, it may cause the...Read more
