But the .65mm spacing doesn't work: "Metric shrink small outline SMT packages with 0.65 mm spaced pins and 323 mil total width are called MSSOPn. NOTE: To be confirmed." sch2pcb produces: "U7: can't find PCB element for footprint MSSOP28 (value=unknown)" Regards, David Koski [EMAIL PROTECTED] !.nospham
