LandNavigator - SMD metal mask design support software
"Land Navigator" is the Land, the optimal shape of a mask, and the simulation software of a Size which carry the past abundant mounting track record datas by Panasonic Factory Solutions.
Reliable result can be checked by calculating fillet volume automatically from a Lead Style in an instant.

Summary
Establishment meter technique of realizing the high yield
"Land Navigator" computes the optimal fillet volume from the Lead-Dim and land width of Parts, and determines the Size and position of a Land / Resist / Mask.
By this, the The number of times of a trial production can be reduced sharply, and the mask Size which can be mounted stable can be computed.
By this, the The number of times of a trial production can be reduced sharply, and the mask Size which can be mounted stable can be computed.
Design by an optimization rule realizes stable mounting.
"Land Navigator" has adopted various optimization rules.
An optimization rule Name and concrete contents are described at the following.
| Optimization rule Names | Concrete contents |
|---|---|
| Proper fillet volume Determination | Fillet model is created according to an electrode Style. |
| On a continuation Printing disposition | Mask opening corner Top R grant |
| Parts swimming prevention | Optimal land width Setup solder ball occurrence prevention classified by electrode Style |
| Solder ball occurrence prevention | Optimization of a Printing Clearance |
| Red eyes prevention | Land corner R grant |
| On a visual check disposition | Minimum Land pushing-out Length reservation |
| ICT correspondence | Reservation of a pin reliance space |
| Side ball prevention | Home base type mask opening |
| Manhattan phenomenon prevention | Optimal Land layout |
| Bridge prevention | Optimal land width Setup classified by pin |
| Lead open prevention | Land with a projection |
| Printing secured mask opening | Required opening size calculation |
| Parts body solder crushing prevention | Optimization of a Land layout |
Interface to printed circuit design CAD
In "Land Navigator", a space output is possible.
Moreover, it is manageable by a spreadsheet by the file output function of CSV.
By being interlocked with a "Parts SaverF'z+", the Land / Resist / mask designed by "Land Navigator" can be used by a CAD system as it is.
