Vias are covered with soldermask and are not processed with HASL or ENIG. Boards with 6+ layers are upgraded to Epoxy Filled & Capped Via for free.
Soldermask is removed over the via and its annular ring. The via will be solderable and has the same surface finish as regular pads.
Boards with 6+ layers are upgraded to Epoxy Filled & Capped Via for free.
Vias should be at most 0.5 mm in diameter to avoid incomplete filling. Vias violating this size will be left unfilled.
Vias are filled with epoxy resin and then plated over with copper to create a flat, solderable surface. Ideal for via-in-pad, multilayer boards, and thick boards.
Vias should be at most 0.5 mm in diameter to avoid incomplete filling. Vias violating this size will be left unfilled.
Vias are filled with high thermal conductivity copper paste and then plated over to create a flat, solderable surface. The filling has an excellent heat conductivity of 8 W/m·K ideal for via-in-pad and heatsink pads.
| Precision routing | OK | NG |
| Example |  |  |
| Description | Alignment holes at both ends of the board allow good positioning | Alignment holes off to one side of the board; position would be inaccurate |
1. PCB must contain alignment holes. (⌀ 1.0 mm minimum, circular, preferably non-plated)
2. At least 3 alignment holes are required.
3. Alignment holes should be placed across the PCB and not clustered together.
4. Individually routed boards need to be at least 50×50 mm for precision routing.
5. Boards in panels only need to satisfy the alignment hole diameter requirement to use precision routing.
