Hardware Hacking Misc PS1/2 Help with solder Point A and F for installing modchip on SCPH 90000

[mobuis09]

So im gonna mod my scph 90000 console with super 7 modchip cause its the cheapest one out there (need to control my budget)
it has the same diagram as modbo 5.0 but the problem is the solder point a and f which it doesnt have a hole. I can solder it if it had a hole
But there is no hole in it. If you mod your scph 90000 series on your own please tell me how you done it. The motherboard is gh 070-42
