To: Technet I am wondering if anyone has found errors in the IPC SM782 LAND PATTERN CALCULATOR. I feel that there may be a calculation error in the land patterns for the TSOP, MT48LC1M16A1TG-10S,MICRON part. The minimum Toe fillet (Jtmin) is defined as 0.005 mm, and the minimum Heel filet is defined as 0.01 mm. This seems to be exceptionally small. Also the Y ref given for the pad is 0.751mm. The resulting pad is quite small and difficult to solder to.(We found it extremely difficult when using these dimensions on a prototype board.) If anyone has had the same problem or a similar one with land pattern dimensions from this calculator, please drop me a line.
