Yeah, but in the UK, they misspell '****', which rhymes with 'bit', as '****e', and apparently, it rhymes with 'white'. Those Brits just don't know how to speak proper English. ;-) Cheers! Rich |

Maybe they liked the look. We just gave them the Gerber for one tiny board, and told them what we wanted to do. Routing halfway through the PTHs is apparently a common thing to do. It worked fine.

If you haven't looked at Digi-Key AND Newark AND Mouser, you haven't even begun to shop. Sure. However, IME a non-stock situation for all versions of a part at Digikey is a warning sign. At least for me. OTOH this has also brought me consulting work (design out) when people ignored such flags. Mostly they were able to scrape together a few hundred but later it really hit the fan, or in production speak a line stop situation. -- Regards, Joerg http://www.analogconsultants.com/ |

The original design used a MAX9690, an SO-8 1 ns ECL comparator, and there were two other sources, for slightly slower parts. The 9690 had a bad fab problem and began failing after about a year of use. By that time, the other sources were gone. Maxim replaced it with the "drop-in" 9691, except that they added back-to-back diodes across the inputs... on a COMPARATOR! So we had to do the kluge board, with added diodes and stuff. As I mentioned, they did sample us 3200 pieces of the 9691. Analog Devices makes the best comparators lately, down in the 200 ps sort of range. But none of this sort of stuff is multi-sourced. John |
