PRE-Assembled Rabbit Adapter Boards - 1.27mm --> 0.10 ???

Aaaaugh !!!

Teenie-tiny pin schemes may be ok for robots, but not for human assemblers.

Rabbits 2mm scheme was bad enough, but now I'm working with the RCM-3400 which shrank everything down to a solder-bridge-guarenteed 1.27mm layout.

Rabbit does sell what it calls an adaptor board ... but you get a board and some SM sockets YOU have to solder onto the thing. This doesn't fix the underlying problem ...

So, has anyone run across a manufacturer who makes PRE-assembled adaptor boards for Rabbit modules ... ie has 1.27mm sockets already attached and then expands them to 0.10 pins ordinary Joes can easily work with ?

If they're gull-wing pins then you solder them on by first globbing on solder to make a huge solder bridge, then using solder wick to suck off the excess and leave a nice solder joint on each pin.

Works like a charm.

Has anyone investigated inexpensive microscope solutions? This job is doable with a sharp naked eye or a loupe, but it's a heck of a lot easier with an assembly microscope.

I used to do it this way, but now I find that I get just as good results - if not better - by tacking down the corners of the part, then putting a metric buttload (must be metric; no inch-pound-foot- acres) of flux on the PCB, and bringing the iron and solder in as close as possible to parallel to the PCB plane and pin direction. Few if any bridges result.

I believe it is also essential that the mixture used in the flux be specified in MKS units.
