Hi Ioan, If that results in less stand-off, it is a negative for reliability. Werner -----Original Message----- From: Ioan Tempea <[log in to unmask]> To: [log in to unmask] Sent: Fri, May 14, 2010 10:26 am Subject: Re: [TN] LPP footprint Chris, Longer pads help visual inspection and allow for touch-ups, so they are good for assembly. I don't know though how they impact reliability. Regards, Ioan Tempea, ing.

I've seen that for a newer LPP footprint recommendation from National, the pads extend a bit beyond the part. In the past they were typically the same size as the contact areas of the component. I'm guessing the change is to aid with AOI. Anyone care to confirm or refute? Happy Friday, -Chris This e-mail message is intended only for the use of the intended recipient(s).
