—-From PCBWorld The Fourth Regional Comprehensive Economic Partnership Agreement Leaders’ Meeting was held on November 15. The ten ASEAN countries and 15 countries including China, Japan, South Korea, Australia, and New Zealand formally signed the Regional Comprehensive Economic Part...Read more -
How to use the “multimeter” to troubleshoot the circuit board
The red test lead is grounded, the pins in the red circle are all locations, and the negative poles of the capacitors are all locations. Put the black test lead on the IC pin to be measured, and then the multimeter will display a diode value, and judge the quality of the IC based on the diode val...Read more -
Common testing technology and testing equipment in PCB industry
No matter what type of printed circuit board needs to be built or what type of equipment is used, the PCB must work properly. It is the key to the performance of many products, and failures can cause serious consequences. Checking the PCB during the design, manufacturing, and assembly process is ...Read more -
What is a bare board? What are the benefits of bare board testing?
Simply put, a bare PCB refers to a printed circuit board without any through holes or electronic components. They are often referred to as bare PCBs and sometimes also called PCBs. The blank PCB board has only basic channels, patterns, metal coating and PCB substrate. What is the use of bare PC...Read more -
PCB stackup
The laminated design mainly follows two rules: 1. Each wiring layer must have an adjacent reference layer (power or ground layer); 2. The adjacent main power layer and ground layer should be kept at a minimum distance to provide larger coupling capacitance; The following lists the stack from ...Read more -
This improves the PCB manufacturing process and can increase profits!
There is a lot of competition in the PCB manufacturing industry. Everyone is looking for the smallest improvement to give them an advantage. If you seem to be unable to keep up with the progress, it may be that your manufacturing process has been blamed. Using these simple techniques can simplif...Read more -
How to do PCB small batch, multi-variety production plan?
With the intensification of market competition, the market environment of modern enterprises has undergone profound changes, and enterprise competition increasingly emphasizes competition based on customer needs. Therefore, the production methods of enterprises have gradually shifted to various a...Read more -
PCB stackup rules
With the improvement of PCB technology and the increase in consumer demand for faster and more powerful products, PCB has changed from a basic two-layer board to a board with four, six layers and up to ten to thirty layers of dielectric and conductors. . Why increase the number of layers? Having ...Read more -
Multilayer PCB stacking rules
Every PCB needs a good foundation: assembly instructions The basic aspects of PCB include dielectric materials, copper and trace sizes, and mechanical layers or size layers. The material used as the dielectric provides two basic functions for the PCB. When we build complex PCBs that can handle ...Read more -
The PCB schematic diagram is not the same as the PCB design file! Do you know the difference?
When talking about printed circuit boards, novices often confuse “PCB schematics” and “PCB design files”, but in fact they refer to different things. Understanding the differences between them is the key to successfully manufacturing PCBs, so in order to allow beginners to...Read more -
A good way to apply copper to PCB
Copper coating is an important part of PCB design. Whether it is domestic PCB design software or some foreign Protel, PowerPCB provides intelligent copper coating function, so how can we apply copper? The so-called copper pour is to use the unused space on the PCB as a refer...Read more -
10 PCB heat dissipation methods
For electronic equipment, a certain amount of heat is generated during operation, so that the internal temperature of the equipment rises rapidly. If the heat is not dissipated in time, the equipment will continue to heat up, and the device will fail due to overheating. The reliability of the ele...Read more
