Heat sinks work by conducting heat away from a source to fins that use convection, and their wide surface area to dissipate heat into the surrounding environment. The convective heat loss formula, Q=Hc*A*(T1-T2), shows that the surface area,
To increase the processing speed and reduce the power consumption of electronic devices, the microelectronics industry continues to push for increasingly smaller feature sizes. Realizing this miniaturization will require the development of robust resist materials as templates to transfer circuit patterns into device-useful substrates such as silicon. 
Infrared thermography is an incredibly useful tool with a wide range of users from home owners looking for energy leakage to engineers analyzing the thermal performance of machines to scientists performing basic research. Unfortunately thermal imaging cameras are often expensive and require proprietary software.
The 2018 California “campfire” wildfire caused more than $16 billion dollars of damage and took more than 85 lives thus exposing serious flaws in our electrical infrastructure. The fire was started when a simple piece of hardware called a “C hook” failed.
We propose a low-cost circuit using commercial off-the-shelf components that enables the measurement of electrical currents in the order of pA range. The circuit presents an output current that is an amplified version of the current to be measured,
Instead of walking to the mail box and finding it empty, or not yet delivered, have a mail box sensor that detects opening, and change inbox volume, and sends notification to a smart phone. The sensor would be battery operated, and should last two years.
IntroductionHigh reliability for electronic systems/assemblies is critical for various industry sectors and their continued success. Electronic devices include Printed Circuit Board (PCB) as the key component for optimal operation/performance. Selection of the materials used in PCBs is critical to make the assemblies highly reliable and free from corrosion.
