I'm looking at this recommended pattern for a Dallas/Maxim BGA that's quite unlike anything I have seen before. http://pdfserv.maxim-ic.com/arpdf/DS32kHz.pdf This BGA has two columns of nine 25 mil eutectic balls at 50 mil pitch on either side of the package. The recommended pattern consists of 28 mil diamond shapes. Has anyone used this pattern? Comments?
