Recommendations for PCB pad dimensions

 

 

 

 

 

 

 

Ball pitch [mm]

2

 

Solder resist opening diameter A [mm]

 

1,150

 

Metal pad diameter B [mm]

 

1 ± 0.05

Placement of microvias not covered by solder resist is not recommended inside the “Solder resist opening”, unless the microvia carry the same signal of the pad itself.

Holes in pad are allowed only for blind holes and not for through holes.

Recommendations for PCB pad surfaces:

Finish

Layer thickness [µm]

Electro-less Ni /

3 –7 /

Immersion Au

0.05 – 0.15

Properties

good solder ability protection, high shear force values

The PCB must be able to resist the higher temperatures, which are occurring at the lead-free process. This issue should be discussed with the PCB-supplier. Generally, the wet-ability of tin-lead solder paste on the described surface plating is better compared to lead-free solder paste.
