Ok, have to decide whether to default to 0603 or 0402 for resistors and
stuff on a new design. Wow, this time I am not size constrained.
Looking at Digikey it comes up with 143 pages (has risen) for 0402
resistors and 218 pages for 0603. Looking at prices 0603 still has a leg
up, around $0.003 for a 10K while its 0402 counterpart runs about twice
that. Is 0603 going to be a good choice for the next years? Or better
stick to 0402?
Of course from a debug point of view I hate to deal with 0402. With
chips the situation seems to be more clear cut. Things definitely seem
to be going TSSOP there.
My production people hate 0402's... they tombstone a lot. We still use
0805's when there's plenty of room, 0603's for tight stuff, occasional
0402's for picosecond stuff where it matters.
You can still buy lots of 1206's and 2010's and such. They're not
going away.
Looks like some parts are appearing only in those drecky
leadless/chipscale packages. Yuk.
