Thanks to those who offered advice. The designer has now been in touch
and explains that the active devices (one or two when placed in contact
with one another) should be secured via a mounting screw inserted from
the outside, through a mounting bush and then the heatsink (with a
suitable thermal pad on the other side. This gives the right insulation
and thermal transfer.

But isn't this the standard way of mounting a device with a 'live' tab?

Sounds to me like being gobby is the way to go, then, as long
as one's surrounded by cute women!

Probably is--this is the first time I've assembled such a kit, so I'm
learning as I go along. :-) The kit just said in the standard way, with
no further details given.

Ah - right. I thought when you mentioned standard mounting kit in your
first post, you'd got one to hand.

Maplin in the days when they did their own kits enclosed a Constructor's
Guide with every one, which gives clear instructions and diagrams for all
this sort of thing. If you send me your address, I'll post you one - being
a good Aberdonian I throw nothing out. ;-) It's a very useful booklet.
