In our daily life, it is manufacturers who mark the shelf life of foods. They are responsible for the quality of the foods and should follow any guarantees about the quality within the shelf life. Things happen the same with the PCB industry.PCB Storage ConditionsDifferent from other productions, the storage condition of PCB requires a strict restriction on air and water contact. First, the vacuum seal of PCB boards can not be damaged, and operators should coat the box with a layer of bubble film. The bubble film has good water absorption capability and plays a good role in moisture-proof function. Also, placing some moisture-proof beads can achieve this purpose to some extent. Figure 1 Importance of water-proof PCB coatingAfter sealing, the box should be stored off the ground and kept in a dry and ventilated place away from direct sunlight. Secondly, temperature and relative humidity control are essential within the standard range based on factory regulation. The storage time of P...
AOI in PCB and SMT Production Line

PCBs are expected to function correctly according to the project specifications. To ensure product quality, PCB manufacturers should institute a variety of inspection techniques during the different production procedures. If the critical errors are identified and fixed at an earlier stage, the cost can be minimized. The development of surface mounting technology (SMT) and the miniaturization of electronics components brings increasing complexity of PCB design and a geometric increase in the number of solder joints on a board. Some traditional testing techniques such as manual visual inspection can no longer meet the modern quality control requirement. Automated Optical Inspection (AOI), based on the principle of optics and a combination of image acquisition, analysis, computer software, and automatic control technology, is able to detect and process the defects encountered in production in real-time. It is now widely applied in the PCB manufacturing and assembly process. Figur...

i would share to you my last project, the project is Linear Adjustable CC CV power supply Module, it can handle DC supply output up to 30VDC, and the output can be adjustable between 2.5VDC to 30VDC, the main components on this projects are OP AMP for measurement and shunt resistor for detecting current passing the load using Ohms's law where V= i x R. for example let's we have a look to picture belowwhen load was applied and current flowing trough Load and Shunt resistor (R_Shunt) there will be some voltage drop between point A and point B if the voltagae drop is 0.1V and R_SHUNT is 0.1 Ohm so the current can be found with simple formulaV = i x R0.1V = i x 0.1Ohmi = 0.1/0.1i = 1 Amp in this casehere is full shcematic diagram

The popularity of IoT PCBs keeps increasing by the day in the technology space due to the huge benefits they offer in modern technology. IoT PCBs have several applications in the tech industry, making their demand soar by day. It is important to understand how this revolutionary technology works so that its full potential can be realized. This article aims to help you increase your knowledge about IoT PCBs. It contains super useful information about these PCBs that will help broaden your knowledge. What is IoT PCB?IoT is an abbreviation for the internet of things. Internet of things simply means a network of electronic devices uniquely designed to communicate with other devices on the internet. This is made possible because these devices are built with sensors, software, and other technologies. A typical example of the internet of things is connecting your mobile device to your fridge to view inside your fridge via an installed app on your phone. Even when you are away from home, ...

5G PCBPCBs are the main structure on which electronic components for various devices are built. Aside from making electronic connections possible in electronic devices, PCBs also receive and transmit digital, analog, high-frequency signals. The PCBs for most current devices are built to 4G PCBs. That is, those devices were designed to suit 4G systems. The 4G network has low speed and bandwidth channels when compared to 5G. To be more specific, 4G systems function at frequencies between 600MHz to 5.925Hz - thus below 6 GHz. But in recent times, the world is gradually advancing towards 5G networks for super-fast signal transmissions. The advent of the 5G network means devices - mobile, telecommunication devices, etc would require high-speed PCBs that suit 5G. This is because the 5G network is required to operate at higher frequency regions of 26 GHz, 30 GHz, and 77 GHz depending on the type of application. This will make the 5G network 10 times faster than the 4G network. The...
Top 4 Common Surface Finishes Comparison｜Pros & Cons

In the wake of developments in science and technology, PCB manufacturing technology improves a lot. Every field in electronic technology urges PCB manufacturers to elevate the corresponding technology in PCB fabrication. When it comes to printed circuit boards which are in a computer or a mobile phone, materials like gold or silver are adopted, leading to a larger gap among different printed circuit boards. What Is Surface Finish PCB surface finish is an inter-metallic joint between the bare copper of the solderable area of the printed circuit board and the components. How Does Surface Finish Affect PCBThere are three different colors in the printed circuit board surface finish: gold, silver, and light red. Gold is the most expensive, silver is second, and light red is the cheapest. It is easy to judge from the color of PCB whether manufacturers did shoddy work. 1. Bare Copper BoardThe traces inside the board is mainly pure copper, that is, bare copper board. Bare Copp...
What Are Commonly Used Components on PCBs?

The PCBs are the physical support of electronic components and the carrier for their electrical interconnection. The components on a PCB work together to form the basic parts of an electronic system. Depending on the devices a PCB is designed for, different components are used for different projects. As electronics products are becoming more and more complex with greater functionality, knowledge of components becomes essential. In this article, we will have a look at some common components used on a PCB. Types of electronics componentsTechnically there are 2 kinds of components, passive and active components based on their functionality. Passive components refer to electronic components that do not affect the basic characteristics of the signal and only allow the signal to pass without modification. They do not need any form of electrical power to operate. Instead, active components depend on an external power source for their operation. 1. Passive components: resistors...

PCB files generate at the time of PCB design or PCB layout. Manufacturing can’t take place successfully without a complete PCB file. Moreover, offering a single PCB schematic does no make an effort to PCB fabrication. Manufacturers need the files that contain installation place of components and illustration connected relationship of every part to build a satisfying PCB board. Image Courtesy:integre The category of PCB files1. Categorizes by traditional file extensions.1.1 pcb. is the commonest file extension in the PCB industry. Many PCB design files using “pcb.”, which are mostly generated from Protel, PADA, and Cadastar, CR5000 from ZUNKEN, also Altimum from P-CAD, etc. What’s more, some Gerber files generate “pcb.” file extension, which can be opened with CAM350.1.2 brd. is a file extension that comes from Cadence Allegro and Eagle. 1.3 max. is from another PCB design software in Cadence called OrCAD.1.4 min. is the file extension that is output from OrCA...
