Testers for integrated circuits are designed for quick, high-quality and safe testing of the operation of integrated circuits of various series. Use PWM devices if you need to check the microcircuit for operability, check the damage of the microchip blocks or detect fake microcircuits. Chip testers are made in the form of sets for DIY DIY assembly. Such sets can collect adults and children. Chip testers also contain interesting and useful functions for radio amateurs, such as an adjustable voltage converter with a voltmeter, a zener diode test, or other functions that are specified in the specifications of each tester. DIY testers are designed for electronics enthusiasts, electronics repair engineers, and manufacturing.
