Recent years has witnessed miniaturization, integrity and modularization of electronic products, leading to the escalation in terms of assembly density of electronic components and decrease in terms of effective thermal dissipation area. Therefore, thermal design of high-power electronic componen

Quite often a printed circuit board (PCB) design will contain both an analog section and a digital section. The analog section typically conditions a signal for digitization and the digital section converts the analog signal to a digital one and then acts on the now digital domain signal. Segreg

Most PCB designs start out with a correct and verified schematic in hand. The hard work of then converting the schematic design into a final PCB must then be undertaken. Quite often, the PCB will fail to workeven though the original circuit design has been undertaken with care. Even if a schemati

As far as high-speed electronic systems are concerned, the success of printed circuit board design directly leads to the high problem solving in Electro Magnetic Compatibility (EMC) system in both theory and practice. In order to reach the EMC standard, high-speed PCB design is facing great chall

Printed Circuit Board (PCB) design is essential to the work of electric engineers and it's not apparently easy to design a perfect PCB. A perfect PCB derives from not only its rationality of component selection and distribution but its high signal conductivity as well. In this thesis, the kno

Printed circuit boards, also known as PCBs, form the core of every electronic piece today. These small green components are essential for everyday appliances and industrial machines alike. PCB design and layout is an important component of any products function - this is what determines the s

It's estimated that over half electronic components fail due to high stress resulting from thermal environment. Recent years has witnessed wide devices of large-scale and hyper-scale integrated circuits (ICs) and surface mount technology (SMT) and electronic products start embracing developme

Rectangular SMC (surface mount component) or SMD (surface mount devices) The size design of rectangular SMC or SMD is shown in Figure 1 below. Rectangular SMC (surface mount component) or SMD (surface mount devices) The size design of rectangular SMC or SMD is shown in Figure 1 bel

Settings of Pad-Trace Connection • When pad is connected with the ground with a large area, cross grounding and 45° grounding should be first considered. • The length of leads drawn from the ground with a large area or power lines should be more than 0.5mm and the width less than 0.4mm. •

Lots of uncertainties are available on RF (radio frequency) PCB (printed circuit board) design that is therefore described as "black art". Generally speaking, when it comes to circuits at frequency below microwave (including low frequency and low-frequency digital circuit), careful layo

There seems no direct correlation occurring between PCB (printed circuit board) vias plugged with solder mask and via copper. However, badly-performed solder mask plugging possibly leads to destructive results on PCBs. As a type of special technology for stencil printing, solder mask plugging tec

As more and more devices are connected into Internet in wireless ways, electronic engineers are confronted with lots of challenges such as how to make radio transmitter assembled to present equipment space and how to design and manufacture devices with increasingly smaller sizes. Moreover, they a

As electronics products witness their fast development, market calls for increasingly higher demands for flex-rigid PCB (printed circuit board) and impedance control PCB simultaneously together with increasingly rigorous requirement on them. The leading issue flex-rigid PCB with requirement on im

BGA (ball grid array) assembly is totally compatible with soldering assembly technology. Pitch of chip-scale BGA can be 0.5mm, 0.65mm or 0.8mm and plastic or ceramic BGA components feature wider pitch like 1.5mm, 1.27mm and 1mm. BGA packages with fine pitch are more easily damaged than ICs (integ

Q1: How to choose PCB (Printed Circuit Board) material? A1: PCB material has to be selected totally based on the balance between design demand, volume production and cost. Design demand involves electrical elements that should be taken into serious consideration during high-speed PCB design. I

PCB (Printed Circuit Board) is quite a core in electronic products that it is applied in almost all appliances of different fields, from small to big, from computers, telecommunications to military hardware. Simply speaking, PCB plays a significant role in implementing functions of electronic pro

No engineer expects defects to occur to his/her PCBs (Printed Circuit Boards). However, some commonly-seen PCB design issues are hardly figured out sometimes due to environmental aspects, improper applications of PCB board or even pure accidents. Thus, engineers should stop accidents from taking

Nowadays, electronic products call for miniaturization and high accuracy so that component miniaturization has become an essential development trend. When miniaturized components are ready to be assembled on large-area PCBs, much higher requirement has to be laid to board smoothness. Naturally, i

PCB, short for Printed Circuit Board, is the fundamental platform to carry electronic components to achieve corresponding functions. Based on substrate material, PCB is fabricated in conformity with PCB design files with connection achieved between board layers, board and components. The leading

PADS is a PCB design package developed by Mentor Graphics. It comes in three trim levels (Standard, Standard Plus and Professional), and is considered as a high end commercial grade software package. It has a number of high end features, including signal integrity analysis functions, an advance a
