Save the date! On September 12th and 13th, 2019, right after PCB West, Sierra Circuits will host a Signal Integrity and Power Integrity Workshop presented by Keysight Technologies Heidi Barnes and Tim Wang-Lee, author of our how to solve signal integrity problems: the basics. The event will take place at our boardroom at the Levi’s Stadium.

The cross-section or micro-section analysis is a visual inspection method of measuring the quality of a manufactured printed circuit board. It’s basically a failure analysis that detects and verifies what went wrong inside the PCB.

In PCB soldering temperature and time must be tightly controlled, if you aim for a better outcome. It’s a balancing act, indeed. PCB assemblies require processing at a high temperature for a long enough time period for good solder joints. But again overshooting the temperature or heating, the assembly too quickly can damage components. Also, insufficient heating can cause poor soldering and long-term reliability issues. The only way to get time and temperature just right is to measure and analyze. This is what is thermal profiling.
The aviation and aerospace industry has witnessed significant growth over the past few years owing to the rising investment by various space and aviation agencies across the globe. It is estimated that the number of aircraft carriers will double over the next two decades.

Doctors are like that supreme power on earth. They have been here, treating people since almost stone age. But as time advanced, the criticality, as well as success rates of the treatment of doctors, also advanced. Their skills and dedication have remained constant throughout time. So what changed? If you look closely, the secret behind this exponentially rising success rate in healthcare is the technological advancements. Medical technological advancement is vaguely synonymous to electronic machines in here which in turn is completely dependent on PCBs. Therefore, we can say the advancements in the medical sciences in recent times are a result of collective efforts. The knowledge of both human anatomy and electronic anatomy (read PCB), drives the healthcare situation. Continue reading “Medical PCBs: The Revolutionary Evolution in Healthcare”
As the electronic devices are shrinking in size, the pitch size is drastically decreasing. The components are getting packed on a PCB like the grains in an ear of corn. All these things have led to one of the most efficient component package, the Ball Grid Array (BGA). Continue reading “Ball Grid Array (BGA): Features, Soldering Technique, and X-Ray Inspection”
Spacing is important, whether it’s in your day-to-day life or in the PCB industry. Consider, you have a noisy neighbor, won’t you prefer to have more space between you? PCB traces are no exception. The worst part is all of the PCB traces are noisy. Well, you can deal with your noisy neighbor (just call 911!), but a noisy PCB trace is another story.
