Notes:
1. The dry film photoresist is usually 0.2mm expanded by the hole edge. When the hole diameter is no less than 5mm, the annular ring must be 0.2 mm at least.
2. The table above is applicable to automated plugging equipment only, not applicable to vacuum plugging equipment.
For flex – rigid boards, vacuum plugging equipments are needed:
A. For positive film, the Max. tenting diameter is Φ 2.5 mm, the Max. slot hole is 1.0 mm * 3.0 mm; if NPTH hole > 2.5 mm, 2nd drilling is needed.
B. For negative film, the Max. tenting diameter is Φ 1.2 mm, the Max. slot hole is 1.0 mm * 2.0 mm; if PTH hole > 1.2 mm, go through the positive film process.

Finished copper thickness ≥ 60 um Unavailable. Linemask process supported with green / matte green solder resist if demanded.
* For boards that require ≤20 um in solder mask thickness over traces, the finished copper thickness should be no more than 40 um. The upper limit – 25 um in solder mask thickness over traces is advised . If not accepted, a review process is needed.
* For boards with BGA pitch ≤0.4 mm that require finished copper thickness within 40um, solder mask thickness by default is 30 um if no specific requirents are proposed. Only screen printing is available.
