In PGA packaging, processor pins are soldered to copper pads on the processor rather than on the motherboard. Although this design makes it easier to repair pin damage in some cases, the process becomes more difficult when the pad is completely gone.
Bits und Bolts rebuilt a critical damaged data pad on a 1.2 GHz Tualatin PIII processor using solder mask and solder. Following the repair, the processor operated at 1.6 GHz with overclocking and outperformed Pentium 4 and AMD Athlon processors from the same era with similar or higher frequencies.
Why it matters
This example shows that physical damage in PGA-packaged processors cannot always be resolved through direct component replacement, and that rebuilding the contact surface can also be a repair option. This is particularly relevant to designs that use copper pads on the processor instead of sockets on the motherboard, highlighting the difference between the nature of the damage and the feasibility of repair. However, the method becomes more complex when the pad is completely missing; therefore, not all damage can be repaired to the same extent. The test result also shows that physical repair is not limited to getting the processor working again, but can enable performance comparable to that of period processors with similar or higher frequencies after overclocking.
