Today to discuss an incredibly important aspect of mobile repair - a definitive method to remove the shields from the motherboard. For this task, my assistant, Leonardo, has given me the chance to experiment with two mini Dremels, also known as precision cutting tools.
Starting at the 23-second mark, I shared my first impression of the two Dremels. These tools, while seemingly minor, can make a world of difference in the mobile repair profession. Given their affordability, they are definitely worth adding to your workshop.

At the 1:41 mark, we ran the second Dremel through a test. Just by holding it, it felt sturdier and heavier than the first one, promising a more solid performance. After cutting with it, we used a microscope to analyze the result in more detail.
At the 2:51 mark, we put the cuts under the microscope. The second Dremel did a fair job, but it was a bit time-consuming. In our profession, efficiency is everything, and the time it takes to complete a task can significantly impact our overall workflow. After making the initial cuts, we easily removed the shield with cutting pliers.
My personal opinion, which I shared at the 3:39 mark, is that while these tools are useful, I still prefer using hot air to remove shields. I find the process quicker and more efficient, even though it requires some experience and a bit of courage initially. Despite this, having a Dremel is essential for dealing with intricate tasks like cutting screws and small shields.
At 4:10, I demonstrated my method of using a hot air station for shield removal. I use a temperature of 400ºC with an 80% air flow. In just 30 seconds, the shield was off, showcasing the efficiency of this method. This way, the motherboard doesn't overheat, because the temperature doesn't reach the circuits' melting point of 220ºC.
So, there you have it. For me, hot air remains the most effective way to remove shields from motherboards. But remember, having a Dremel in your toolkit can come in handy for more precise tasks. And as always, I'm joined by Leonardo, my trusty assistant, who's been there every step of the way. We hope this tutorial has been enlightening and we look forward to seeing you in the next one. Bye for now!
