Impedance Control of PCB

As circuit design becomes increasingly complex and high-speed, how to ensure the integrity of various signals (especially high-speed signals), that is, to ensure signal quality, has becomes a problem.At this point, will take advantage of transmission line theory to analyze. Control signal characteristic impedance matching becomes the key point. Non-strict impedance control will cause considerable signal reflections and signal distortions, leading to design failures. Common signals such as PCI bu...

What is Automated optical inspection(AOI)

Automated optical inspection (AOI) is an automated visual inspection of printed circuit board manufacture where a camera autonomously scans the device under test for both catastrophic failure (such as missing component) and quality defects.It is commonly used in the manufacturing process because it is a non-contact test method. This guarantees the high reliability of Multi-CB multilayer circuit boards.It is especially important for the following application areas:l Line width violationsl Spaci...

What is HDI PCB

High density interconnect (HDI) PCB, represent one of the fastest growing technologies in PCBs. Because of its higher circuitry density than traditional circuit boards, the HDI PCB design is able to incorporate smaller vias and capture pads, and higher connection pad densities. HDI Boards contain blind and buried vias and often contain micro vias of 0.006 or less in diameter. By using HDI technology, designers now have the ability to place more components on both sides of the raw PCB if desired....


PCB material classification

What is PCB?A printed circuit board (PCB)mechanically supports and electrically connects electronic components using conductive tracks, pads and other features etched from copper sheets laminated onto a non-conductive substrate. Components are generally soldered on the PCB.-Printed circuit boards are used in all but the simplest electronic products. They are also used in some electrical products, such as passive switch boxes. The base pcb material (CCL-Copper Clad Laminate) is a composite materi...

The difference between immersion gold and gold plating

Gold plating: Gold plating is a method of depositing a thin layer of gold onto the surface of another metal through plating way. The gold particles attached to the pcb, as strong adhesion also known as hard gold. The gold finger of memory bank is hard gold and abrasion resistant. Immersion gold: Immersion gold through chemical reaction to make gold particles attached to pcb. As weak adhesion it is also known as soft gold.Why use gold plating?As IC become more and more integrated and IC pins are ...

What is ball grid array (BGA)

A ball grid array (BGA) is a type of surface-mount packaging used for integrated circuits. BGA packages are used to permanently mount devices such as microprocessors. A BGA can provide more interconnection pins than can be put on a dual in-line or flat package, each pin is provided with a solder ball. All connections are distributed in a uniform surface grid or matrix on the component. The whole bottom surface of the device can be used instead of just the perimeter. The leads are also on average...

General introduction of SMD Adhesive

SMD Adhesive is also called Surface Mount Adhesive.Before soldering, components with pin contacts or SMDs are often bonded to the PCB with adhesive. This allows, for example, several capacitors, electrolytic capacitors and coils to be positioned on a circuit board and cured within just a few seconds to prevent their falling over or sliding out of position on the PCB. The secured components can then be reflow-soldered in a single work step, which saves time and speeds up production. The SMD adhes...

What is Electronic test/probe test

Combine Automatic optical alignment system and the traditional flying needle machine together,with the help of image-processing software and flying-pin-only cameras, flying probe test is easier and more accurate.The electronic test for circuit boards is performed after manufactured. All the pcb manufactured by PCBWay must be checked with flying probe test. The layout is analysed according to the pcb file for short circuits and interruptions. This is important because only the E-test detects inco...

Comparison of several PCB surface finish types

PCB surface finish is a coating between a component and a bare board PCB. It is applied for two basic reasons: to ensure solderability, and to protect exposed copper circuitry. As there are many types of surface finishes,selecting the right one is no easy task, especially as surface mounts have become more complex and regulations such as RoHS and WEEE have changed industry standards.HASL(Hot Air Solder Leveling) / Lead Free HASLHASL is the predominant surface finish used in the industry. The pro...

Flexible PCB vs Rigid PCB

Flexible PCB (also variously referred to around the globe as flex circuits, flexible printed circuit boards, flex print, flexi-circuits) are members of electronic and interconnection family. They consist of a thin insulating polymer film having conductive circuit patterns affixed thereto and typically supplied with a thin polymer coating to protect the conductor circuits. The technology has been used for interconnecting electronic devices since the 1950s in one form or another. It is now one of ...

What is Rigid-Flex PCB?

Rigid-Flex printed circuit boards are boards using a combination of flexible and rigid board technologies in an application. Most rigid flex boards consist of multiple layers of flexible circuit substrates attached to one or more rigid boards externally and/or internally, depending upon the design of the application. The flexible substrates are designed to be in a constant state of flex and are usually formed into the flexed curve during manufacturing or installation.Rigid-Flex designs are more ...

Aluminum PCB vs FR-4 PCB

What is Aluminum PCB?Among all Metal core PCBs, Aluminum PCBs is the most common type - the base material consists of aluminum core with standard FR4. It features a thermal clad layer that dissipates heat in a highly efficient manner, while cooling components and increasing the overall performance of the products. Currently, Aluminum Backed PCBs is regarded as the solution to high power and tight tolerance applications. Price ComparesFR-4 PCB is a very conventional PCB type of electronic industr...

What are Plated Half-Holes(Castellated Holes)

Plated half holes(castellated holes)are holes that made off the edge of the boards plated withcopper using a specialized process. It is predominantly used for board-on-board connections, mostly where two printed circuit boards with different technologies are combined.Through connecting the PCBs together directly, the whole system is considerably thinner than a comparable connection with multi-pin connectors. The plated edges are also useful in producing mini PCB modules. Plated half holes are av...

What is the meaning of Glass Transition Temperature (Tg)

The Glass Transition Temperature (Tg) is one of the most important properties of any epoxy and is the temperature region where the polymer transitions from a hard, glassy material to a soft, rubbery material.Circuit board material must flame-resistant, it can’t be burned at a certain temperature and only be soften. The temperature point is called the glass transition temperature (Tg).The higher Tg point means higher temperature requirement during lamination. And the boards will be hard and crisp...
