Werner, Thanks for the info - forgot to mention in my initial email that through-hole solder joints are my primary concern, rather than surface mount ones. Early testing has shown the potential for cracking/tearing of solder joints on wire links that I am bending after soldering (not unexpected!) I have extremely limited scope to get tooling into the area to support the solder joints and ensure bending occurs well clear of it. It's all a messy business and basically a product on which design-for-manufacture has gone out to lunch...all I can do at this late stage (no major changes to the product possible) is try to ensure that whatever steps we take in assembly result in a sufficiently reliable product - in this case it's an emergency lighting control so that reliability has to be good.
