I am new to SIR test and have several questions needing help.

     1. Where do I get SIR test coupons or Gerber data? The places I know
     are IPC-B-25/28/36, Topline "saber" array and Microtek Lab.

     2. What are the differences among these different IPC coupons?

     3. Any pros and cons of IPC, Saber and Microtek?

     4. Do all these test patterns have pad patterns for standard component
        such as QFP, SOIC, TSOP etc.?

     5. Any abbreviated SIR tests?

     Thanks!
