A |
blind via (drilled depth-controlled) |
Ø ≥ 0.20 mm, AR 1:1 |
C |
buried via (resin filled) |
Ø ≥ 0.20 mm, AR 1:9 |
|
E |
microvia (laser drilled) |
Ø ≥ 0.10 mm, AR 1:1 |
|
F |
blind via (resin filled) |
Ø ≥ 0.20 mm, AR 1:9 |
|
G |
through via (mechanically drilled) |
Ø ≥ 0.20 mm, AR 1:9 |
|
AR = Aspect Ratio |
"Aspect Ratio" is the ratio between drilling depth and diameter.

K |
calculate 50 µm for drill tip |
L |
effective drilling depth (Aspect Ratio max. 1:1) |
|
M |
min. 150 µm insulation distance to the next active layer |
K drill tip depends on hole diameter*
*Beispiele:
hole diameter | 0,2 drill tip | 50 µm |
hole diameter | 0,3 drill tip | 70 µm |
hole diameter | 0,4 drill tip | 90 µm |
