# pcbStands (advanced)

The pcbStands object has a few optional parameters:

```

   Optional:
    p(2) = Height to bottom of PCB from inside of base: Default = standoffHeight
             negative measures from inside of the lid to the top of the PCB
    p(3) = PCB Gap : Default = -1 : Default for yappCoordPCB=pcbThickness, yappCoordBox=0
    p(4) = standoffDiameter    Default = standoffDiameter;
    p(5) = standoffPinDiameter Default = standoffPinDiameter;
    p(6) = standoffHoleSlack   Default = standoffHoleSlack;
    p(7) = filletRadius (0 = auto size)
    p(8) = Pin Length : Default = 0 -> PCB Gap + standoff_PinDiameter
             Indicated length of pin without the half sphere tip. 
             Example : pcbThickness() only leaves the half sphere tip above the PCB
    n(a) = { <yappBoth> | yappLidOnly | yappBaseOnly }
    n(b) = { <yappPin>, yappHole, yappTopPin } 
             yappPin = Pin on Base and Hole on Lid 
             yappHole = Hole on Both
             yappTopPin = Hole on Base and Pin on Lid
    n(c) = { yappAllCorners, yappFrontLeft | <yappBackLeft> | yappFrontRight | yappBackRight }
    n(d) = { <yappCoordPCB> | yappCoordBox | yappCoordBoxInside }
    n(e) = { yappNoFillet } : Removes the internal and external fillets and the Rounded tip on the pins
    n(f) = [yappPCBName, "XXX"] : Specify a PCB. Defaults to [yappPCBName, "Main"]
    n(g) = yappSelfThreading : make the hole a self threading hole 
             This ignores the holeSlack and would only be usefull 
             if the opposing stand if deleted see sample in Demo_Connectors

```

#### p(2) - Height to bottom of PCB

Well, it defines the height of the pcbStand which is useful if a pcbStand needs to be of a different height than the default (f.i. if you have more than one PCB that needs to fit in your projectbox.

#### &#x20;p(3) - PCB Gap

This defines the thickness of the (f.i.) second PCB\
Take this code:

```
pcbStands = 
[
    [pcbLength-7, 5, yappAllCorners]
//-- (0), (1), (2),(3),(4),    (5),     (6),(7)
   ,[70,   5,  10,  5,  6, default, default, 1]
   ,[70,  40,  10,  5,  6, default, default, 1]
   ,[100,  5,  10,  5,  6, default, default, 1]
   ,[100, 40,  10,  5,  6, default, default, 1]
];
```

The first entry will create four 'standard' pcbStands based on the size of the PCB.\
The next four entries will create one pcbStand each for a second PCB that is 5mm thick \[p(3)] and that stands 10mm above the base \[p(2)]. The fillet radius \[p(7)] for each of these stands is set to 1mm.
