The situation involving moisture sensitivity of plastic integrated circuits (ICs) has been steadily getting worse, due to a number of industry trends, including the continued pursuit of higher reliability products to support critical communications and technology applications. Failure rates for moisture-sensitive devices (MSDs) alone are already at an intolerable level, coupled with the ongoing changes…
I. Circuit online test technology In order to ensure the functional test of the device on the circuit board, the logic level of the drive device must be forced, and each pin driver must be able to absorb or output sufficient current. According to the post-drive safety standard recommended by the international protection standard document…

This article guides you through the process of transforming Gerber files into functional PCB layouts. Learn the essential steps to recreate your designs efficiently and effectively while minimizing the challenges of manual layout redos.
This article explores the importance of Gerber files in the PCB design process, detailing how they facilitate manufacturing by providing crucial layout information for custom PCB production. Ideal for both novices and experienced designers.
Packaging refers to connecting the circuit pins on the silicon chip to the external connector with wires so as to connect with other devices. The packaging form refers to the shell used to install the semiconductor integrated circuit chip. It not only plays the role of installing, fixing, sealing, protecting the chip and enhancing the…
This essential guide explores the significance of Gerber files in PCB fabrication, detailing their role in the design and manufacturing process, along with practical tips for preparing and submitting these files to custom PCB manufacturers.
The two most critical processes that help successfully rework SMT are also the two most easily overlooked issues: Appropriate preheating of the PCB before reflow; 1.Quick cooling of the solder joints after reflow. Since these two fundamental processes are often overlooked by rework technicians, in fact, sometimes the condition after rework is worse than before…
Fill means drawing a solid copper sheet, connecting all the connections and vias in the area together, regardless of whether they belong to the same network. If there are two networks, VCC and GND, in the drawn area, the Fill command will connect the elements of these two networks together, which may cause a short…
IC packages rely on PCBs to dissipate heat. Generally speaking, PCBs are the primary cooling method for high-power semiconductor devices. A good PCB thermal design can have a huge impact on the system’s good operation or the potential for thermal accidents. Careful handling of PCB layout, board structure, and device mounting can help improve the…
PCB copy board refers to the service of redrawing PCB data based on existing products (finished products\circuit boards) for re-production when there is a lack of PCB data and the circuit board cannot be produced. Generally speaking, PCB copy board is faster and has better quality than re-developing products, because a PCB design to mass…
The interconnection of the circuit board system includes three types of interconnection: chip to circuit board, interconnection within the PCB board, and between the PCB and external devices. In RF design, the electromagnetic characteristics at the interconnection point are one of the main problems faced by engineering design. This article introduces various techniques for the…
Although the current EDA tools are very powerful, as the PCB size requirements are getting smaller and smaller and the device density is getting higher and higher, the difficulty of PCB design is not small. How to achieve a high PCB routing rate and shorten the design time? This article introduces the design skills and…
PCB copper-clad laminate is the substrate material for making printed circuit boards. In addition to supporting various components, it can also achieve electrical connection or electrical insulation between them.The manufacturing process of PCB copper-clad laminate is to impregnate glass fiber cloth, glass fiber felt, paper and other reinforcing materials with adhesives such as epoxy resin…
This article explores efficient gerber fabrication techniques to streamline PCB production, discussing strategies for optimizing file outputs, reducing unnecessary data, and improving overall workflow in the circuit board design process.
