A printed circuit board is a panel or plate made up of one or a pair of conductive patterns. They are located on the surface of the dielectric base. In some cases, a system of conducting patterns located on the surface and in the volume of the dielectric base is used. The main purpose of printed circuit boards is to mechanically fasten quantum electronics and electronic technology, as well as to connect them electrically. Varieties of printed circuit boards The simplest option is a plate with copper conductors on one side, connecting the elements of the conductive pattern only...

  Gemology microscopes come with advanced features, though they’re easy to use. Some also include the ability to assign saving folders which helps with organizing images, or features that allow you to annotate images. Ring holders, gemstone and diamond stages, and light boxes are specially designed accessories you can find on some gemology microscopes that help aid in delivering the best imaging results. Below are some of the salient features of a good gemology microscope. Zoom adjustment The location of this feature can be at the top or on the sides of the microscope’s head. It...

How to fix the SMD parts in the proper position when soldering? This is a  predicament that everyone will encounter. So am I. Whenever I have PCB's that need to be filled with SMD parts I have to double check this, and as the pin spacing gets tighter this has become an issue.Modifying some bent tweezers with rubber bands to improve grip is able to help hold the components in place until 1 or 2 pins can be soldered. This method works, but it can be very tricky. We can also try a variety of glues and...
