Printed Circuit Board Heat Sink Features/Functions
Heat management is essential for living on this earth as weather and devices affect buildings, vehicles, and equipment. Thermal management is also necessary for printed circuit boards, as they will get damaged if they can’t dissipate the heat their components generate. Besides, the board also gets hot due to soldering during manufacturing. Hence, heat dissipation methods become mandatory to increase the PCB speed [1]. Though FR4 is good at heat management, sometimes it is not enough when there is a high-speed circuit board. Likewise, the power supplies also generate heat and you have to install heat sinks and insulators. You must ...
Metal Core and Metal Black Printed Circuit Board
Printed Circuit Boards [1] are a crucial component of any electronic device, but the materials used to manufacture them can significantly affect the performance and durability of the device. Metal core and metal black PCBs are two types of PCBs that offer numerous benefits over standard FR-4 PCBs. Here, we will explore the advantages of using metal core and metal black PCBs in electronic projects. We will discuss how they can improve their performance and reliability, as well as their suitability for a variety of applications. When it comes to a circuit board design, the metal core and metal black printed ...
Drill, Lamination, and Plating of PCB Design
Understanding Drilling PC Board [1] drilling involves different drilling machines which can make more than 30,000 holes in an hour. The machines have built-in systems for making precise holes and consist of spindles that can drill at a high speed of up to 110,000 RPM. An automated system and laser help manage drill bits to provide high-quality vias. Drilling Of Through-Hole Vias Standard PCBs have a through-hole where all PCB layers are drilled together under an NC machine. Then comes the plating of the holes’ inner and outer sides, and manufacturers use the same technique for all through holes, including the mounting holes. Blind ...
SMT Assembly and Thru-Hole/Chip Functionality
Printed circuit boards are parts of various electronic devices, home appliances, and vehicles. The function of these green chips depends on their material and assembly technology. Each step of PCB assembly [1] is important and needs careful processing considering essential features. Two methods are popular in PCBA, including, MT and THT. Let’s study them in detail. Through-Hole Technology (THT) Traditional PCB has through whole technology, involving both automatic and manual processes. THT is PCB packaging technology that involves pins or leads, besides, you have to insert the chips in the PCB through holes, soldering from below. The technique gives it the name through-hole. Through-hole ...
PC Board Electrical Schematic and Its Functionality?
Whatever we create, including a PC Board,is a picture or an idea that we convert to paper in the form of a diagram. You can’t proceed with manufacturing without a proper PCB layout or schematic. An electrical schematic is a conceptual plan or drawing that helps understand the physical aspect of a PCB in terms of assembly. The basic purpose of electrical schematicsis [1] to have design communication.It should help manufacturers clearly understand it.Besides, the schematic directs you to makea PCB layout. Schematics involve specific elements which are essential to understand, such as: REFDES or reference designates Symbols representing the components Outputs Nets To know schematics in detail, ...
