Why Are Printed Circuit Boards Made In Layers?
PCBs are in nearly every technological device we use today. Their primary functions are: 1. To electrically connect electronic components and 2. To provide mechanical support (e.i. the electronic components are permanently soldered to the board). PCBs are built in layers similarly to a lasagna. These layers are made of different materials in order to provide structure, Read More
Introduction to SMT Stencils for Printed Circuit Boards
Also known as solder paste stencils or solder stencils, they are usually sheets of stainless steel (or polymer) with apertures. They are designed to deposit solder paste on printed circuit boards but they can also be used to deposit other materials like glue, flux or thermal grease onto a substrate.
