   	 		 			|  			 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.  			 |
