Analog changeover switch : 2oz copper mountable

[treez]

Hello,
We wish to use this Analog changeover switch, but our PCB company tell us the feature size is too small for our needed 20z copper. I cant find a SOIC 8 one anywhere.
(or similar package)....do you know of one

TS5A12301E datasheet:

Fairchild have some "bus switches" that may be available in something compatible with 2Oz copper.

Widely used by radio hams building switching mixers, they are up in that 'possible, but fiddly' to hand solder region, so I would have thought they should be possible for this.

Regards, Dan.

Thanks, ill have a look, much appreciated.

Advanced PCB companies (including pool providers like Multi CB) have 200 µm structure size for 2 oz copper which would still work with dual row 0.4mm BGA.

But a brief look at the TI product selection shows that are also similar types in SOT23 etc.

Second one has about 150 options...
