The aluminum substrate is a kind of metal-based copper-clad laminate with good heat dissipation function, and it is the basic material of high-power power electronic circuit structure technology and interconnection technology. In Aluminum Substrates PCB proofing, the single-sided aluminum substrate is generally composed of a three-layer structure, which is a circuit layer (copper foil), an…
1. Multilayer circuit board is a kind of printed circuit board that is laminated and bonded by alternating conductive pattern layers and insulating materials. The number of conductive pattern layers is more than three, and the electrical interconnection between layers is realized through metalized holes. 2. Comparing the production processes of the two parties, the…
With the development of science and technology, LED technology is also constantly developing, bringing all kinds of convenience to our lives, providing us with all kinds of life information, and benefiting us human beings. If you want the LED switching power supply to have the best PCB components layout, then before proceeding with component layout…
Multilayer Circuit Boards are generally used in high-speed PCB design. Multi-layer circuit boards are actually formed by laminating and bonding several etched single-sided or double-sided boards. Multi-layer circuit boards are compared with single and double-layer circuit boards. , There are many advantages, especially in small-volume electronic products, let’s share the advantages of multi-layer circuit boards…
FPC is also called flexible circuit board and soft board. It has the characteristics of high wiring density, lightweight, and thin thickness. It is a highly reliable and excellent flexible printed circuit board. FPC is divided by function, which can be divided into FPC antenna, FPC touch screen, FPC capacitive screen, etc.; FPC cable is…
PCBA (Printed Circuit Board Assembly) is the board obtained after all printing solder paste on the PCB and then mounting various components like resistors, ICs (Integrated Circuits), capacitors, and any other components like transformers depending on the application and desired characteristics of the board. PCBA Production usually undergoes reflow furnace heating to establish a mechanical…
There is a very common process used in the surface treatment of circuit boards, which is called the immersion gold PCB process. The immersion gold process is to deposit a nickel-gold plating layer with stable color, good brightness, flat plating, and good solderability on the surface of the printed circuit. During production, the cost of…
In our daily production, we will pay attention to the quality control of SMT processing, and ignore the cleaning process after PCBA manufacturing. We believe that cleaning is not a key technical step. So, where is the importance of PCBA cleaning for circuit boards? 1. PCBA production goes through multiple stages, and each stage is…
With the development of PCB technology in the direction of high density and refinement, the role of multi-layer PCB boards is becoming more and more important and widely used in various fields. and there are a lot of questions about multilayer PCB circuit boards associated 1. How many layers does a multi-layer PCB board have…
PCBA board processing belongs to high-precision manufacturing and must comply with relevant actual operating rules. So, what are the precautions for PCBA board processing? 1. During electronic PCB processing, the surface to be soldered cannot be taken with bare hands, because the grease secreted by human hands will reduce solderability and easily lead to soldering…
