What is the best book to learn about microscopy?
A great book to learn about microscopy is Introduction to Light Microscopy by Douglas B. Murphy. It is a comprehensive and up-to-date introduction to the fundamentals of light microscopy, and covers the basics of both optical and digital microscopy. It also offers detailed guidance on choosing, setting up, and operating a microscope, as well as tips on proper specimen preparation and troubleshooting.
Can I extract anything from compare two sheets?
Yes, you can extract a lot of data by comparing two sheets. Depending on the type of data, you can compare the content of the two sheets to identify any discrepancies, discover commonalities, calculate differences, and more. For example, different versions of a document can be compared to find changes and additions, and two spreadsheets can be compared to find differences in the values of their cells.
How to format a GPT partition?

Why PCB surface finish is important in PCB manufacturing?
PCB surface finish is essential to the manufacturing process as it directly affects the connectivity and performance of the board. The allowed tolerances for the components and solder paste are small and therefore the surface finish of the board must be free from burrs and contaminants in order for the components and solder paste to meet these requirements. Without a quality surface finish, components can easily be misaligned and cause electrical problems, or the solder paste won’t adhere properly, leading to open circuits and solder joints that can fail. PCB surface finish also plays an important role in heat dissipation and protection from harsh environmental conditions. The material used to create the surface finish can be an insulator that helps protect the board from moisture and temperature changes, or they can be thermal conductive materials that work to swiftly dissipate heat away from components. While surface finishes typically add cost to the manufacturing process, their ability to improve the reliability and longevity of the PCB make them well worth the investment.
