Instead of convenient pins, BGA parts have tiny metallic balls on which solder is applied, a board is thrown through a reflow oven, and hopefully at the end, everything works. Sometimes these ...

From there, some general soldering tools like flux and solder wick, a stencil for your chip, BGA balls, and a $20 USB-C hotplate are instrumental for reballing chips – tools you ought to have.

The leaked image showcases an unsoldered PCB with a large BGA (Ball grid array ... If you look at the VRAM layout in the leaked PCB photo, there are a total of 16 solder pads around the main ...

With FPGA packages exceeding 1,000 pins, with Ball Grid Array (BGA) solder bumps providing the interconnect, it is vitally important to make solid contact with the Printed Circuit Board (PCB).
