Cdev,

Yes there is. I used to run a subcontract bare board test laboratory. I had a universal grid single density machine with a cassette structure for its bed of nails function.

Spring loaded probes ( some 30,000 odd thousand ) were interposed between test electronics points and user accessible 0.1" pitch universal grid which carried job specific fixture built with rigid probes.

The spring probes were covered with a "striper" plate which exposed heads of spring loaded probes and engaged with the bottom plate of job specific fixture.

The only thing that changed in this kind of setup would be job specific fixture.

I have used my sidewards interface at 0.05" pitch in a CNC mill. PCB misalignment is the major factor in the deal. If you can't get the pins straight enough in thick FR-4/G10 block, I imagine you might try using a plastic like acetal or hdpe. There's no grain in the plastic and it makes for straighter drill holes.

I know that is the intended way, that doesn't mean you have to do like that

Langwadt,

So true. I have built a little programing fixture based on 6 pin AVR  pattern. Pins had some programing issues so i drilled a small second layer PCB to straighten out the pins and simply used super glue and bicarbonate of soda to hold it all together.

Bicarbonate of soda acts as an instant hardener of super glue.
