Dongguan shielding cover manufacturers tell you why the shielding cover has holes-hardware

I received a phone consultation from a friend today: They use a lot of shielding covers and need to develop a Dongguan shielding cover manufacturer, but he does not understand why the shielding cover has holes? My friend is a purchaser, and he understands that he is not familiar with the technology. However, it seems that after so many years, no one has asked such a question. So, the group of people around the shielding material, performance and why the shielding cover is used, as well as the general production status of the Dongguan shielding cover manufacturer, first gave this buddy a talk about it. Furthermore, when the components in the shield work, heat energy is generated, and if the heat energy is not dissipated in time, and there is no heat dissipation hole, it is easy to burst in the product shield and tell him again. After confirming the sending of the drawing, I hung up the phone happily, and felt the joy of the customer after the constant efforts to solve the problem and create value for the customer, and I felt the joy in my heart inexplicably.
