LineLine    alignment tolerance: ± 0.045mm;
     Minimum line width: 0.1/0.1mm;
Solder    mask1. Unspecified ink thickness is controlled as follows (customer    specified ink thickness is controlled according to customer    requirements)
     1 line surface: ≥10um;
     2 line angle: ≥ 8um;
     3 substrate: ≥ 15um;
     2. Coaming ink    thickness: 70~120 um;
     3. Soldering    resistance alignment tolerance: ±0.045mm;
     4. The minimum width    of the solder mask line:
     ① Surface copper 1OZ minimum width: 0.075mm;
     ②Surface copper 2OZ minimum width: 0.10mm;
     ③Surface copper 3OZ minimum width: 0.15mm;
     ④Surface copper 4OZ minimum width: 0.175mm;
     5. Solder mask film    minimum window opening: minimum line width: 0.15mm
Remarks: The ink adopts sulfur-free    and halogen-free ink with excellent high temperature resistance and high    reflectivity, and can withstand the eutectic welding process without falling    off and discoloration.
Silk ScreenThe    minimum character line width is ≥0.15mm;
     Character alignment tolerance ≥0.15mm;
     The minimum character diameter is ≥0.75mm;
     The minimum character gap is ≥0.15mm;
Surface    Treatment1.ENIG: No special requirements from    customers  Gold thickness: 0.025 ~    0.075um, Nickel thickness: 4 ~ 8um; if required by customers, it is    controlled as required.
     2.Immersion Ag:Ag    thickness: 0.2 ~ 0.5um.
     3.Immersion Tin:Tin    thickness is 0.5-1.5um according to normal requirements.
     4.OSP:The film    thickness is 0.2-0.5 um according to the conventional requirements.
Laser    profile1. The closest distance of the    cutting line to the line: 0.2mm; (coating the protective layer and laser    marking, single-sided lines can be lined from the back)
     2、Alignment of upper    and lower cutting lines: ±0.02mm; (double-sided stencil control    alignment)
