CAM350 is the industry standard for PCB verification, optimization and output generation to efficiently and effectively drive PCB fabrication.
More and more complicated PCB designs require comprehensive verification before they are transferred to the PCB manufacturer to ensure a perfect and timely produce of bare PCB boards. Problems emerging during the PCB manufacturing can effect the product schedules, result in costly design re-spins, and require modifications to the design that might compromise the PCB design’s intent and integrity . Inspecting, preparing and validating the PCB design before releasing to manufacturing will lead to a vital increasement in efficiency, less risk of design re-spin, and, most importantly, successful electronic products, faster time-to-market, but at less cost.
CAM350 provides a full suite of tools, from design through production, streamlining the transition of PCB design data into right and real PCBs. following are two tips of CAM350 helping the customer to master this great tool.
When the text layer in some PCB Gerber data has a lot of text box,and the distance between text box and PAD can not meet the process capability.When the Gerber data has a large area of copper foil cover, the distance between lines or PAD and copper is beyond to the production requirements, and the outline size is big…You can draw on the experience of treatment methods of this article.
One,When the Gerber data has a large area of copper foil cover, the distance between lines or PAD and copper is beyond to the production requirements, and the outline size is big,you can use the below method to rapidly trimming the distance between lines or PAD and copper.
1, Copy all the PAD in the circuit layer( this is the first layer) into an empty layer.Delete the corresponding PAD on the copper sheet and enlarge the rest PAD as a reduction of the line layer(that is second layer).
2, then copy the first layer into an empty layer.Delete the copper sheet as third layer.Combination way is: the first layer , the second layer , the third layer.
In general, in order to reduce the amount of data, we can keep only copper sheet the first layer .If only the distance between welding to copper sheet is not enough,you can copy the welding layer that is enlarged and can meet the process capability into an empty layer.Delete the correspongding sold mask on copper sheet, and enlarge the rest sold mask as second layer.
Note: after using this method to completes the circuit, be sure to use the order: Utilities–>Convert Composite to convert multiple layers into composite,and change this composite to one layer.And then use the order:Anglysis–>Compare Layers to check this layer with original layer carefully .
Two, when the text layer in some Gerber data has a lot of text box,and the distance between text box and PAD can not meet the process capability,you can draw on the experience of below methods :
1, Use the order:Edit–>Move Vtx/Seg to stretch the text box up to specifications,and then make it flash.
2, then make the other text box of the same type the same flash.But note that after making it Flash ,the flash must be broken up, in case of rotation of D date when openning the data next time.
