Who is this masterclass for?
This masterclass is perfect for shop owners, micro-soldering technicians, and ambitious beginners who want to upgrade to a professional level. We start from the absolute basics โ component testing of Resistors, Capacitors, and Diodes โ and take you all the way to advanced CPU micro-soldering, I2C/SPI protocol analysis, and A19 Pro board-level diagnostics. No prior degree required. If you can hold a soldering iron, we will make you a certified iPhone engineer.
