While on work experience at TechHeaven I completed a series of hardware related tasks on phones and on a computer. These tasks consisted of taking apart, replacing, or upgrading internal hardware components.
One of such tasks that i was tasked to do multiple times was taking off the metal “shield” from the inside of a phone.
For this task i would need to use a small range of different magnetic screwdrivers that have different tips. The three different tips that were used were Flat head, Phillips, and Triwing heads. What screwdriver was used depended on the model of the phone. Newer phone models tended to use the Triwing screws while the older ones used the Phillips screws.
These screwdrivers were supplied to me by TechHeaven and were replaced with better quality ones during my time there.
The metal plate that was called a shield was screwed into place with 5-6 screws depending on the model of the phone. Newer model phones had five screws, three on one side and two on the other. Whilst the older models had six screws, three on each side.
Upon removal of the ‘shield’ I was to inspect the metal plating and look for a small apple logo, if this logo was present I was to put the metal sheet in a box with other similar metal plates. If the said logo was not present I was instructed to put the plate in the bin.
The reason for this is because we cannot dispose of commercially branded parts such as the apple branded metal plates without proper practices.
With the screws that was unscrewed, they were put into a small plastic container for use if needed in the future.
There was not many safety precautions as the phones had been turned off and all power was taken away from them. A safety precaution however could be slipping with the screwdriver and stabbing a body part or damaging property. To ensure this would not happen you were to take it slowly and not apply big amounts of pressure.
