IPC-2221 Revision B, “Generic Standard on Printed Board Design,” has just been released and is available now from Document Center Inc. The document is available in both paper and CD Rom format, however the CD Rom does not have the capability to print. For this reason, many users prefer the paper edition or to purchase the “kit” which includes both the paper and CD Rom copies.
IPC-2221B is the foundation design standard for all documents in the IPC-2220 series. It establishes the generic requirements for the design of printed boards and other forms of component mounting or interconnecting structures, whether single-sided, double-sided or multilayer.
Among the many updates to the new Revision B are new criteria for conductor characteristics, surface finishes, via protection, board electrical test, dielectric properties, board housings, thermal stress, compliant pins, panelization and internal and external foil thicknesses. Appendix A provides new test coupon designs used for lot acceptance and quality conformance testing.
This standard is one of our top-sellers here at Document Center Inc. The new 170-page Revision B replaces IPC-2221A from 2003, which is now obsolete.
