KwickFit Optimization Examples	"Using KwickFit for PCB Panelization analysis has provided Jabil with accurate, efficient and cost saving scenarios." - Steve Corke, Jabil Circuit Inc.
The following are just a few examples of how KwickFit's layout optimizers can increase material utilization and reduce costs. The increased yield can quickly add up to significant savings on production runs. KwickFit will pay for itself again and again.
Example 1: Auto Array Matrix Optimization This example illustrates the part per panel yield improvements achieved with KwickFit's Auto Array Matrix layout. KwickFit's array optimizer will analyze various array matrices within a user specified range to find the matrix that produces the highest part per panel yield. This example begins with a 2 x 2 array matrix that yields 80 parts on an 18 x 24 panel. Visually, the array appears to use the manufacturing panel efficiently, but with KwickFit we can easily calculate an array design that improves the part per panel yield as shown below.
The Original Unoptimized Array Array size: 3.186 x 5.586 Part size on the array: 1.2 x 2.4 Part spacing on the array: 0.062 Array borders: 0.362 Panel size: 18.0 x 24.0 Part spacing on the panel: 0.1 Minimum panel borders: 0.65	New KwickFit Auto Matrix Optimized Array Using the same array parameters (part size, spacing, border widths, etc.), KwickFit's Auto Matrix array optimizer calculated a new (6) up array that increases the part per panel yield from 80 to 84 parts per panel.


Example 2: Basic Optimization This example illustrates the part per panel yield improvements achieved with KwickFit's Basic optimizer. This example shows a 2.0 x 3.0 part that yields 56 parts on an 18 x 24 panel. Visually, the layout appears to make efficient use of the manufacturing panel.
The Original Unoptimized Layout Parameters Part size: 2.0 x 3.0 Panel size: 18.0 x 24.0 Part spacing: 0.1 Minimum panel borders: 0.65	New KwickFit Optimized Layout Using the same layout parameters as the unoptimized layout, KwickFit calculated an optimized layout that increases the part per panel yield from 56 to 58 parts per panel by rotating the top two rows of parts 90 degrees.


Example 3: Part Size Optimization An often overlooked area for cost reduction is the part size itself. KwickFit's Analyze Part Size to Increase Yield feature provides a fast and easy means to find potentially hidden optimizations that can be achieved by a minor reduction in part size. Often the required part size reduction is small enough that it's easily implemented. Other times the required part size reduction is to large and not practical but the Analyze Part Size to Increase Yield feature makes it easy to determine if the opportunity for improvement exists.
The Original Unoptimized Part Size and Layout Parameters Part size: 1.895 x 2.875 Panel size: 18.0 x 24.0 Part spacing: 0.1 Minimum panel borders: 0.65	New KwickFit Optimized Part Size With the Analyze Part Size to Increase Yield feature KwickFit found that the the part per panel yield could be increased from 58 to 61 parts if the part size is reduced from 1.895 x 2.875 to 1.895 x 2.872, just .003" in one axis.
