soldering phosphor bronze pins to PCB

[alb]

Hi all,

I'm not sure this is the good place where to post this, please advise a
better NG in case it exists.

I'm working on the soldering process of a component with phosphor bronze
pins onto a fairly standard FR-4 multilayer PCB. The component is a
light detector (MPPC: Multi Pixel Photon Counter) and I still do not
know what is the amount of heat to deal with.

Is there any recommendation on soldering this components on a pre-tinned
pad?
Anything special on thermal behavior which should be considered? For
instance I have seen a power mosfet mounted without stress release on
the soldering point on a the thru-hole one-sided pad that after several
ON/OFF cycles caused the joint to crack.

Any hint is appreciated.

This is a pretty low volume group. You are likely to have better luck
over in sci.electronics.design, so I'll cross-post over to there. There
are some photon pushers that hang around s.e.d regularly, as well as
numerous designers and prototype builders who might have experience with
a similar part.

Of course, if there's a specific part number or datasheet link that you
could post, that would help to narrow the focus.
