PROJECT | PROCESSING CAPACITY | DETAILED PROCESS EXPLANATION |
Production Layer Number | 1~10 floors | According to the design documents, 1~10 layers of perforated plates can be made. |
Maximum Size | 600x600mm | The size is too large to pass the V-cut machine below. |
Minimum Size | 7x7mm | 7mm needs to be reviewed |
Contour Tolerance | ±0.15mm | V-cut plate shape tolerance 0.15mm |
Plate Thickness Specification | 0.4~3.2mm | 0.4/0.6/0.8/1.0/1.2/1.6/2.0 .. |
Thickness Tolerance | ±10% | Copper deposition, solder resistance, tin spraying and other processes will affect the plate thickness. |
Limit Line Width | 5mil(0.127mm) | The line width is larger than 6mil(0.15mm) as much as possible. |
Limit Line Distance | 5mil(0.127mm) | The line spacing shall be greater than 6mll(0.15mm) as much as possible. |
Finished Copper Thickness | 1oz(35um) | 1oz is the conventional steel thickness, which can be increased to 20z and 3oz. |
Mechanical Drilling | 0.25~6.3mm | 0.25 is the minimum aperture and 6.3 is the maximum aperture. |
Hole Tolerance | ± 0.075mm | This tolerance is within the allowable qualified range. |
Minimum Character | Width ≥0.15mm/ height ≥ 0.85mm | The characters are too small, which may lead to ambiguity. |
Distance From Line To Shape | ≥12mil(0.3mm) | Keep a safe distance when gong or V-cut. |
Welding Resistance Type | Photosensitive ink/matte ink | Green/blue/white/black/red/purple oil |
Spacing-free Puzzle | Omm | During imposition shipment, the intermediate clearance is 0. |
Spaced Puzzle | 1.5mm | When the splice spacing is less than 1.5mm, the difficulty of gong edge will be increased. |
