Drill hole size: 0.15-6.5mm
|
||||
Minimum via/pad: Double-side board: 0.2mm (inner diameter)/0.5mm (outer diameter) Multi-layer board: 0.15mm (inner diameter)/0.25mm (outer diameter) ①The outer diameter must be 0.1mm larger than the inner diameter, 0.15mm preferred ②Preferred Min. Via hole size: 0.2mm
|
||||
Minimum trace: This depends up on the copper thickness! (1OZ copper) 0.076/0.076mm(3mil/3mil). Tolerance is 20% so you probably want to set the width to 1mm
