Process flow of Aluminum PCB
With the continuous development and progress of modern electronic product technology, electronic products are gradually developing towards the direction of light, thin, small, personalized, high reliability and multi-function. Aluminum PCB was born in accordance with this trend. Aluminum PCB has ...Read more -
it is broken and separated after welding, so it is called V-cut.
When the PCB is assembled, the V-shaped dividing line between the two veneers and between the veneer and the process edge forms a “V” shape; it is broken and separated after welding, so it is called V-cut. Purpose of V-cut： The main purpose of designing the V-cut is to facilitate th...Read more -
What are the common faults of PCB screen printing?
PCB screen printing is an important link in the PCB manufacturing process, then, what are the common faults of PCB board screen printing? 1, The screen level of the fault 1), plugging holes The reasons for this kind of situation are: printing material dry too fast, in the screen version dry...Read more -
Tin spraying is a step and process in the PCB proofing process.
Tin spraying is a step and process in the PCB proofing process. The PCB board is immersed in a molten solder pool, so that all exposed copper surfaces will be covered with solder, and then the excess solder on the board is removed by a hot air cutter. remove. The soldering strength and reliabilit...Read more -

Matters needing attention in PCB design
1. The purpose of PCB design should be clear. For important signal lines, the length of wiring and processing ground loops should be very strict. For low-speed and unimportant signal lines, it can be placed on a slightly lower wiring priority. . Important parts include: division of power supply; ...Read more -
PCB process edge
The PCB process edge is a long blank board edge set for the track transmission position and placement of imposition Mark points during SMT processing. The width of the process edge is generally about 5-8mm. In the PCB design process, due to some reasons, the distance between the edge of the compo...Read more -
Global and China Automotive PCB (Printed Circuit Boards) Market Review
Automotive PCB research: vehicle intelligence and electrification bring about demand for PCBs, and local manufacturers come to the fore. The COVID-19 epidemic in 2020 slashed the global vehicle sales and led to a big shrinkage of the industry scale to USD6,261 million. Yet the gradual epidemic co...Read more -
Exposure
Exposure means that under the irradiation of ultraviolet light, the photoinitiator absorbs the light energy and decomposes into free radicals, and the free radicals then initiate the photopolymerization monomer to carry out the polymerization and crosslinking reaction. Exposure is generally carri...Read more -
