In AD6.3 and later versions, grooved and non-circular pads can be created, and trenches and square pads can be added to dig holes.

   The detailed drilling types can be seen from the manufacturing steps. Place a special string symbol on your PCB, add an output description on it, and place a legend string symbol on the DrillDrawing layer.

   Note: If the latest software version supports output processing file detection, it is best to check your PCB processing file to see if grooves already exist on your board. In addition, the earliest versions often used methods to describe the grooves on the mechanical layer or solder mask layer, using text description. Some designers place pads or vias that are superimposed on the through hole to define the area of ​​the drilling output, but this may cause the drill bit to be damaged.

   When the irregular hole manufacturing method is different from the next plate structure, you will find that your plate structure is more suitable for being processed. So there are three ways to define grooves

    Add detailed machining information to the mechanical layer

    Add multiple overlapping pads or vias

   Apply CAMtasticNCDrill feature

   For the example of this design, the mechanical layer is usually used to describe the groove information

   The detailed information can be found in the mechanical layer PlatedRouteDetails. Here you can see the connection of the wiring to the grooves of the components J1, J6, J2S. When switching to single layer mode, you can see the initial settings of each layer (shortcut to switch to single layer mode: shift, s)

   The routing details are included in the component so the component is moved when switched.

   Before adopting this path, check the PCB processor to see if the method of setting the dog talent can be accepted.

   For this step, the pad and trench areas must have been established with sufficient support information to the processor as follows:

   Multi-layer pads with holes are set to 0 units, this is the default setting pad area

   The starting and ending pad positions are at the end of the trench position. Set the aperture size for these pads to be the same as the trench size.

   Place a line on the mechanical layer of the plating channel details from the starting center point to the end pad. The width of the line refers to the width of the trench cutout.

   You also need to think carefully about the inner plane connection of the trench pad, leave enough space for the inner plane to place the physical connection, and the hot pad and empty pad need to be set manually. In this PCB example, the thermal pads have been used–create arcs and lines manually, see Pad 1 of J6 for details.

   The connection rules for the power plane connection set for the pads can be directly connected. As for the design rules, check the power plane connection type and set the rule settings to connect directly to these grooves. (Rule: PlaneConnect_Obround_Pads, add a set class for the pad in the design> class can be set in the rule more easily.) When mounted on the board, if you cannot easily connect to the thermal pads, you can choose simple options to connect directly to these trench pads.

   Finally, the trench pads cannot be connected to a flat surface. For example, pads 2 and 3 on J6 need to be copper-coated on the cut-out area. Therefore, a line or other object is added as a flying lead to the cut-out area to connect the internal electrical layer . Because the plane is output from the negative.

   When you export your Gerber file or ODB ++ file, carefully check the connection of the internal electrical layers, remember to include the mechanical layer of Related Routings, and remind your board manufacturer to pay attention to the grooved pads on the PCB.
