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

Posted On 22 December 2022 BY

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, ...

Printed Circuit Board High Copper Weight

Posted On 21 November 2022 BY

High-power PCB applications need more intensive heat management to cope with high currents and this is possible only through a heavy copper PCB. The copper thickness of traditional PCBs ranges between 1oz. and 3oz. whereas, the thickness of heavy copper goes from 4 oz to 10 oz. There is also another category of a heavy copper PCB known as a super-copper PCB which is 20oz to 200oz per square foot. Such a PCB is suitable for applications that need a high amount of current and high-power thermal or heat management. Heat dissipation in a large PCB becomes easier due to thick copper. ...

Copper & Epoxy Filled Vias in a PC Board

Printed circuit boards [1] have holes made through drilling to electrically connect various PCB layers. Manufacturers have to fill vias with different materials which are conducive or non-conductive, including copper, epoxy, etc. Via filling helps reduce air or liquid trapping, thus enhancing a PCB’s function. If anything gets trapped in the hole, it would affect the PCB assembly at a high temperature which is essential for soldering without lead. Via Filling Through Via-In-Pad The via-in-pad is the latest technology to fill vias, however, it is more costly than the old methods, such as through-hole. HDI boards with micro-vias work better because of ...
