You can create grooves and non- circular hole pads AD6.3 version and subsequent versions , add pads to dig trenches and square holes .
Details can be seen from the type of drilling manufacturing steps, the special burst of symbols placed on your PCB board, and add the output described above , is placed in a burst of symbols legend DrillDrawing layer .
Note: If the latest software version supports output processed file detection , it is best to detect what your PCB processing files, to see if your board has been in existence grooves. Further , the first version of the method commonly used in the mechanical layer comprises a solder resist layer or the grooves described using text description mode . Some designers are placed in the overlap region sequence or the pad via the through -hole drilling to define the output , but this may cause the drill bit to be destroyed.
When irregular holes manufacturing method differs from the next board structure, you will find that your board structure is more suitable to be processed. Therefore, there are three grooves define
Adding detailed information to a mechanical layer processing
Adding multiple overlapping pads or vias

For an example of this design , mechanical layer is usually used to describe a trench information , see LiveDesignEvaluationBoard example , 'EB1_Spartan_ll_1_02.PcbDoc' the PCB in the folder [\ \ Program | file :/ / / \ \ program] Files \ AltiumDesigner \ Examples \ LiveDesignEvalationBoard \ referenceDesigns \ LiveDesignEvaluationBoard (EB1EB2) \ Spartan_Specific \ SpartanIIIBGA4561.02EB1
Detailed information can be found in the mechanical layer PlatedRouteDetails , here you can see the wiring connections and components J1, J6, J2S trench connected . Conversion to single- mode initial situation can be seen on each floor ( to switch to single- mode shortcut : shift, s)
When more information is included in the wiring element will move the switching element so .
Before using this path , check to see if the PCB processors set Goucai way be accepted .
For this step , the pad and the groove area has been established to be sufficient to support the following information to the processor :
Multi- pad with holes is set to 0 the unit , which is the default pad area
Starting and ending positions of the pads located at the end position of the groove , the aperture size settings for these pads to the same size of the trench .
Details on the mechanical layer coating channel placed the center line from the start to the width of the pad , as of the reference line trench dug cut width.
You also need to seriously think of the plane groove connection pads , leave enough space for physical connection to the plane , while the thermal pad and the pad will need to manually empty set . In this example the PCB thermal pad has been used - to create arcs and lines manually , see J6 pad 1.
Set of rules for the connection pads connected to the power plane can be directly connected . As design rules, see the power plane connection type setting rules set up a direct connection to these grooves, ( rule : PlaneConnect_Obround_Pads, the pad is designed to increase an already set class > class can more easily be set in the rule . ) when assembled to the plate , if you can not easily be connected to the thermal pad you can simply choose the option to connect directly to the grooves on the pad .
Finally , the groove can not be connected to the pad plane , e.g., on the pad 2 and the J6 3 requires copper pads on an empty area of the cut , thereby increasing a line fly line or to other objects connected to the inner shear layer region . Because the plane is the negative output .
When you export your Gerber or ODB + + files when the file , carefully check the electrical connections within layers , remember to include Platedroutingdetails mechanical layers , and to remind you to pay attention to the board manufacturer trench pad on the PCB .
