The calculator freeware supports a dozen component families, including: ball grid array, ceramic flat pack, ceramic quad flat pack, leadless chip carrier, metal electrode face, molded body, plastic leaded chip carrier, quad flat pack, small-outline IC, small-outline J-lead, small-outline transistor, and transistor outline.
IPC-7351, Generic Requirements for Surface-Mount Design and Land Pattern Standard, relies on dynamic calculations that represent a change in the way land patterns are defined, developed, and categorized. It is published by IPC, a worldwide trade association and standards-development organization. To get a free copy of the calculator, go to www.PCBLibraries.com.
Revision A now includes land pattern design guidance for lead free soldering processes, reflow cycle and profile requirements for components and new component families such as numerous forms of chip array packages and \"pull-back\" QFN and SON devices.
Open-source hardware accelerates the time to market and reduces development risk, as designers can easily develop a custom carrier board based on their specific interface requirements and budget constraints. We simplify the process of developing a custom carrier board that is compatible with our System on Modules (SoMs) by offering free reference designs, tools and documentation.
For the new pads, I started with the dimensions of the IPC-7351b-recommended oval pad, and then manually modified them to create the chamfered corners. I calc'd the chamfer dimensions to end up with my required clearance between pins on the completed package.
The Saturn PCB Toolkit is the best freeware resource for PCB related calculations you can find.It incorporates many features that PCB designers and engineers are in regular need of like current capacity of a PCB trace, via current, differential pairs and much more.
