Have you noticed that most of the PCBs are green? Unfortunately, there is nothing green about them. Truth be told, the PCB waste generated decades ago will continue to harm our environment in the years to come. The PCB waste consisting of hazardous substances, which include heavy metals such as lead, mercury and cadmium, and several other chemicals, adversely affect life on earth. There is a need for environmentally responsible manufacturing for RoHS compliant PCBs across the entire consumer electronics sector in today’s time. RoHS directive, which stands for Restriction of Hazardous Substances, restricts the use of hazardous materials, particularly found in electrical and electronic components.
Are you familiar with horse racing? Well, of course you are. It is one of the oldest and traditional sports known to mankind. Horse racing involves riders or jockeys riding horses to decide which is the fastest of them over a set course. In horse racing, the eyes of the horse are covered from the side to avoid any distractions. Now, you are wondering what is the relationship between the spacing and horse racing, apart from the two words are in rhyme. Unfortunately, designers behave the same (sometimes) during the PCB design stage.
The cross-section or micro-section analysis is a destructive analysis that measures the quality of the manufactured board. It’s basically an interconnection defect analysis process 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.
Electronic Anatomy or PCBs in Electronics
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”
