New QUAD flatpack geometryΒΆ
In the next dialogbox the parameters for a QUAD flatpack geometry can be entered. The QUAD flatpack geometry is a SMD based device.
The following parameters can be changed:
Nr pins X,Nr pins Y
If the total amount of pins is two times the (Nr pins X + Nr pins Y) entered. The pinnumber counting starts with an optional string and a number. and increments with one for the following pins. The pin counting direction is counter clockwise.
Pad size X,Y
Pitch
Pad size solder mask
If the solder mask pad is not necessary, fill one of the parameters (X,Y) with zero.
Pad size paste mask
If the paste mask pad is not necessary, fill one of the parameters (X,Y) with zero.
Clearance
The initial clearance is the clearance used for this geometry.
Distance X,Y
Starting pin nr
The starting pin nr consists of two editboxes. The first editbox(optional) contains text or a number, and will not be changed. The second editbox contains a start number. This startnumber will be increased with one for the next pads.
The Use default rules for solder paste/mask and clearance button can be used the fill in values based on the pad size.
