Printed circuit board and method thereof and a solder ball land and method thereof
First Claim
1. A printed circuit board (PCB), comprising:
- a first solder ball land having a first surface treatment portion configured for a first type of resistance; and
a second solder ball land having a second surface treatment portion configured for a second type of resistance, wherein a surface material of the first solder ball land is different from that of the second solder ball land.

Abstract
A printed circuit board and method thereof and a solder ball land and method thereof. The example printed circuit board (PCB) may include a first solder ball land having a first surface treatment portion configured for a first type of resistance and a second solder ball land having a second surface treatment portion configured for a second type of resistance. The example solder ball land may include a first surface treatment portion configured for a first type of resistance and a second surface treatment portion configured for a second type of resistance. A first example method may include first treating a first surface of a first solder ball land to increase a first type of resistance and second treating a second surface of a second solder ball land to increase a second type of resistance other than the first type of resistance. A second example method may include first treating a solder ball land to increase a first type of resistance and second treating the solder ball land to increase a second type of resistance other than the first type of resistance.
