 |
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) |

|
|
F |
blind via (resin filled) |
Ø ≥ 0.20 mm, AR 1:9 |

AR = Aspect Ratio |
|||
"Aspect Ratio" is the ratio between drilling depth and diameter.
|
Depth-controlled drilled blind vias |
||
 |
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 |
