In electronics, the terms VCC, VEE, VDD, and VSS are frequently used to describe different power supply voltages in circuits. These designations are essential for understanding the supply roles and the correct functioning of components like bipolar junction transistors (BJTs) and field-effect transistors (FETs).
In PCB manufacturing, engineers need a Bill of Materials (BOM) to organize every component required for their product. A BOM is a vital document for tracking parts, managing inventory, and ensuring production accuracy.
For the whole board positioning of the PCB circuit board and the reference symbols for the positioning of the fine-pitch devices, in principle, the QFP with a spacing of less than 0.65mm should be set at its diagonal position; the positioning reference symbols for the imposition PCB daughter board should be paired Use, place on the opposite corner of the positioned feature.
Blind vias and buried vias optimize space and functionality in multilayer PCBs, essential for high-density designs that enable complex and efficient layouts.
Explore the world of Electroless Nickel Immersion Gold PCBs. Understand their advantages, how they compare with HASL surface finishes, and their growing importance in various industries.
Choosing the right packaging form for integrated circuits is crucial in electronics. BGA and QFN offer distinct features and applications. Factors like pin density, thermal management, and repair ease guide the choice. Transitioning from QFN to BGA may address higher pin density, thermal needs, and market trends, balancing design and cost considerations.
One of the biggest challenges facing PCB designers is not understanding the cost drivers in the PCB manufacturing process. This article is the latest in a series that will discuss these cost drivers (from the PCB manufacturer’s perspective) and the design decisions that will impact product reliability.
The pricing of a bespoke PCB and the variables that affect it will be covered in this article.
Immersion gold PCBs are commonly used in high-reliability applications, such as telecommunications and medical devices.
Two types of copper foils are used for the copper used in substrates. One is "electrolytic copper foil" used for rigid boards, and the other is "rolled copper foil" used for flexible and high-current boards.
This article aims to provide a comprehensive understanding of PCB thickness, factors affecting PCB thickness, and how to choose the right pcb thickness.
The stiffeners PCB mainly include stainless steel stiffeners PCB, aluminum foil stiffeners PCB, polyester stiffeners PCB, polyimide stiffeners PCB and glass fiber stiffeners PCB.
