The Institute for Interconnecting and Packaging Electronic Circuits (IPC) has made the IPC-SM782 Surface Mount Land Pattern Calculator available for computation on the Internet. The IPC-SM-782 has served as the standard for creating independent SMT land patterns since it was released as a written standard in 1987.
Initially, to keep up with the introduction of new technologies, the IPC came up with an electronic spreadsheet for the standard. Thus, designers were able to save considerable time by performing the complex land pattern calculations from component input...
