In this segment of the video, the host is upgrading the soldered 16GB RAM chips in a 2018 A1990 MacBook Pro 15 inch to 32GB capacity. The MacBook Pro belongs to a company called Laskar Sonas Productions. The Mac has a 2.6 GHz 6-core Intel Core i7 processor and the RAM is soldered to the logic board, making it challenging for end users to upgrade. The host discusses the initial quality check process, disassembles the MacBook, and shows how to access and replace the RAM chips to achieve the 32GB capacity upgrade. The process involves removing black sticker covers and replacing 1 gigabyte chips with 2 gigabyte chips.

In this segment of the video, the technician focuses on replacing RAM chips on a logic board. They start by engraving rectangle lines around the RAM chip’s perimeter for positioning, then they use an IR heater to pre-heat the board and remove the RAM chips. The process involves carefully heating the chips from the top while gently moving them until they can be pulled off. After removing all the RAM chips from the top side, the board is cooled, flipped, and the process is repeated on the other side. Once all RAM chips are removed, a visual inspection is done, and any components that may have been knocked off are fixed. Finally, flux is added to the pads, and leaded solder wire is used for wicking off the lead-free solder before cleaning the board with alcohol.

In this segment of the video, the logic board is prepared for new 32GB RAM chips after being cleaned. The serial number for the RAM chip is provided, and solder flux is applied to all 8 RAM footprints on the top side of the logic board. The RAM chips are carefully aligned and soldered using a BGA rework station. The process is repeated on the bottom side of the board. The video then demonstrates adjusting the RAM configuration strap and completing a final quality control test after partially reassembling the MAC to ensure all hardware is functioning properly.
