The second tweezers are made a little differently. Of course, you can buy ready-made gold-plated tips, but this greatly increases the cost of the design. In the process of working with two tweezers, I decided to try to make my own tips from available materials. I experimented with different materials, but in the end I chose copper plates.
The tips must be thin enough, while maintaining good rigidity and stability and have low resistance. Copper plates are perfect for these requirements. The only possible inconvenience is sometimes rubbing the surfaces with fine emery cloth. As you know, copper also comes in different qualities, so it is necessary to use plates well-known manufacturers, such as flexible multi-plate electrical busbars.
Another significant difference from the first tweezers is the distance between the tips. 2 cm and 4.5 cm, respectively. This allows you to measure capacitors of different types with radial leads.
In addition, having a low-impedance range, it is more convenient to look for short circuits on boards at more distant points.
