Circuit Designers And Builders: You Need To Understand IC Packages

By

June 5, 2011

Integrated circuits (ICs) are etched into tiny silicon chips. ICs may be part of larger electronic circuits or they may be a complete system by themselves. These components are packaged in ceramic, plastic, leadless or glass.

The sizes of the packages have assigned names and specifications. Often, we finish design with a particular IC without considering the type of packages available for such IC and the problem of soldering or placing the component shows up.

This is a common problem among hobbyists and students. In order to avoid this in your next project, try and check for the package type before you move on.

The following are the assigned names of some packages with their photos;

CBGA – Ceramic Ball Grid Array

What Lockheed Martin Cyber Attack Must Teach Nigeria – Security Readiness Must Correlate With ICT Penetration

The US defense giant, Lockheed Martin, was hit by cyber attackers, Yahoo News has reported. Because Yahoo News links do expire, we have to put the contents below:

Hackers launched a “significant and tenacious” cyber attack on Lockheed Martin, a major defense contractor holding highly sensitive information, but its secrets remained safe, the company said Saturday.

Lockheed Martin, the Department of Homeland Security and the Pentagon confirmed that the contractor’s information systems had come under attack. Lt. Col. April Cunningham, speaking for the Defense Department, said the impact on the Pentagon “is minimal and we don’t expect any adverse effect.”

Still, the concerted attempt to breach the contractor’s systems underscored the risk to the nation’s critical defense data. Chris Ortman, Homeland Security spokesman, said his agency and the Pentagon were working with the company to determine the breadth of the attack and “provide recommendations to mitigate further risk.”

Now, if this attack has happened in Nigeria, what would have happened? Read Lockheed Martin:

Lockheed Martin said in a statement that it detected the May 21 attack “almost immediately” and took countermeasures. As a result, “our systems remain secure; no customer, program or employee personal data has been compromised.” The company’s security team is still working to restore employee access to the targeted network. Neither Lockheed Martin nor the federal agencies revealed specifics of the attack.

This company reacted immediately and took care of the problem. If the Nigerian security agency was under this attack, do we have a chance. When group of guys in Nigeria attacked some federal websites, it took some of them 24 hours to even know that their sites had been compromised despite the fact that the news was all over the blog-sphere. In this case, you are supposed to be the one that will identify that.

How secure is our national data? As ICT is deployed across all areas of our economy, we need to take a hard look at security. This is simply important. If we build without a security plan, we will suffer huge consequences in this age of cyber warfare.

ADM2682E and ADM2687E – Solutions for Critical Isolation Requirements of Motor, Power and Energy Control Systems

Analog Devices introduced the ADM2682E and ADM2687E, the industry’s first single-chip 5-kVrms signal- and power-isolated RS-485 data transceivers that meet the safety isolation requirements of high voltage systems in motor, power and energy control systems. The new data transceivers also feature ±15-kV ESD protection on the bus pins. The highly integrated data transceivers are designed with Analog Devices’ iCoupler® isolation technology and combine a 3-channel isolator, a three-state differential line driver and a differential input receiver based on Analog Devices’ isoPower® isolated dc-to-dc converter technology.

The new transceivers reduce component count by up to 80 percent compared to discrete competitive options. Packaged in a single 10 mm x 13 mm surface mount package with greater than 8 mm minimum creepage and clearance, the transceivers occupy 70 percent less board space than the multiple discrete components typically used. The ADM2682E and ADM2687E achieve data rates of 16 Mbps (mega-bits per second) and 500 kbps (kilo-bits per second), respectively.

The ADM2682E and ADM2687E extend ADI’s portfolio of isolated bus communication products that includes similar products for other popular industrial and instrumentation protocols, including CAN (Controller Area Network), RS-232, USB (universal serial bus) and I2C. The new isolated transceivers are powered by a single 5-V or 3.3-V supply and integrate a 5-kVrms isolated dc-to-dc converter, which eliminates the need for an external dc-to-dc isolation block.

The devices are designed for the critical isolation system requirements of motor, power and energy control systems. The parts are fully specified over the industrial temperature range of -40 °C to +85 °C and are available in a 16-lead, wide-body SOIC (small outline integrated circuit) package. Safety and regulatory isolation standard certifications are pending for the ADM2682E and ADM2687E drivers and include UL (Underwriters Laboratories), CSA (Canadian Standards Association) and VDE (Verband der Elektrotechnik).

ADM2682E and ADM2687E Key Features and Benefits

5-kVrms isolation per UL1577 meets system isolation needs for safer high-voltage systems.
Integrated isolated isoPower dc-to-dc converter reduces design-time and provides industries smallest footprint.
±15-kV ESD protection on RS-485 input/output pins increases robustness of pins connected to external environment.
8-mm creepage and clearance meets safety requirements for medical applications.

The global network gear, Cisco, this month announced that it is investing $10m in Egypt. This is a five year investment in its efforts towards building strong and healthier global communities. The announced was made in a press release on Cisco website, dated June 02, 2011.

This investment will go towards job creation and economic development in Egypt. The most fascinating aspect of this investment is the model – a venture capital investment targeted at small businesses that provide innovative products, services and solutions. They will also play a role in facilitating investment in Egypt by building collaborations with local, regional and international institutions.

Key highlights of this investment are as follows

Businesses across Egypt are recognizing the need to invest in ICT for new opportunities and growth. While ICT investment in Egypt continues to grow, essentially doubling between 2001 and 2010, ICT penetration still remains low. However, the deregulation of the telecom sector, the dramatic expansion of technology use by the younger generation, and continued investment will accelerate usage in the country.

Cisco is actively working throughout the Middle East and North Africa to support job creation and economic growth by building ICT skills and talent within the workforce as well as providing greater access to capital and to educational opportunities. Developing and addressing the growing skills gap, as well as creating entrepreneurs and leaders of the future, is at the forefront of Cisco’s mission for the MENA region. Cisco has several initiatives in the region to facilitate this, including the Cisco® Networking Academy® and the Cisco Entrepreneur Institute.

There are currently 333 Cisco Networking Academies in Egypt with 655 instructors and a total of 18,716 students of which 43% are women. The program has trained almost 45,827 students since inception.
