How to deal with moisture sensitive components in PCB design

Posted on April 02, 2019 by G

How to deal with moisture sensitive components in PCB design involves the moisture sensitivity of plastic integrated circuits (ICs), which is getting worse and worse, due to many industrial trends, including the use of support for critical communications and The constant search for higher reliability products for technical applications. The failure rate of a moisture-sensitive device (MSD) alone is already at an unacceptable level, coupled with the ever-changing packaging technology. Shorter development cycles, shrinking sizes, new materials and larger chips are causing a rapid increase in the number of MSDs and a higher level of moisture/reflow sensitivity. Finally, the growth in the use of area-arranged packages such as BGA and CSP has also had a major impact. This is because these components tend to be packaged in tape-and-reel systems, each having a large number of components. When compared to the pin components in the IC tray, the key issue is that the exposure to moisture is longer.

POWERPCB tips

Posted on March 29, 2019 by G

PowerPCB enables users to achieve high-quality design and vividly reflects all aspects of the electronics design industry. Its constraint-driven design approach reduces product completion time. You can define safety spacing, routing rules, and design rules for high-speed circuits for each signal, and apply these plans hierarchically to the board, to each layer, to each type of network, to each network, to each group. On the network, each pin is placed to ensure the correctness of the layout design. It includes a wide range of features including clustering tools, dynamic routing editing, dynamic electrical performance checks, automatic dimensioning and powerful CAM output capabilities. It also has the ability to integrate third-party software tools such as the SPECCTRA router.

Fast Positioning of Signal Integrity Problems in High Speed Circuit Design

Posted on November 11, 2025 by G

In high-speed circuit design, the traditional approach to locating signal integrity problems is to use hardware triggers to isolate events and/or to capture events using deep acquisition storage techniques before looking for problems. As the speed and complexity of high-performance circuit systems continue to increase, the limitations of using oscilloscopes to locate signal integrity problems are becoming more prominent.
