Personally I use the complete cufflink mechanisms from Cooksons (NVU-101 you can find them here)
This is what I do for my fine silver (PMC/ACS) fronts onto the Cooksons cuff link mechanisms.
1) File off the little bump so you have nice flat contact
2) Burnish the area on the PMC that you'll be attaching the cuff link too
3) (If using paste) Blob paste onto the cuff link finding
3b) (If using Pallions) Clean and flux both pieces and the solder pallions
4) Hold cuff link finding onto cuff link with cross-locking tweezers (at an angle where you won't burn yourself while heating the piece)
4b) (If using Pallions) put solder pallions at join point
5) Aim the heat at the block around the fine silver cuff link gradually bringing the heat more onto the cuff link. Don't aim the heat onto the solder itself until the the fine silver is hot. The solder tends to melt when the fine silver is around the Salmon red colour.
6) Remove heat when the solder flows BUT continue to hold the cuff link finding in place as the solder will still be fluid until the metal cools a bit.
7) Pickle & polish as normal

I put more here in my 
Babette makes very, very detailed custom name stamps and makers marks that are perfect for adding that professional touch to all your polymer clay and pmc pieces. They're made from a hardened plastic that gives perfectly crisp text impressions.
The back of the flower pendant shows the other stamp I bought. This one has the "Created by Heart and Hand" logo used on my business cards and website. I only had crude graphics for this, but Babette got them tidied up for me and they came out beautifully.
This is the first piece, a shaped rolled rope ring, with inset CZ and carving. I also had to oxidise it but took the picture before that (so you could see the carving depth better). It also had to end up an exact size (did that bit phew!)
For the second piece you have to set a natural stone using fine silver bezel strip. The stone is bezel set post firing and a part of the pendant has to be mirror finished. The stone is a very pretty green Tourmaline & you can see the textured silver through it (cute). 
This is the back showing the Fine Silver Bail back (or flat screw eye) which has to be used. It also shows the new name stamp I got from the fabulous Babette Cox! 
The final piece is a brooch, this one requires the use of syringe type clay. It also uses Art Clay Exclusive brooch findings which are always fun to set, lol. I really hope this one passes as I might have been a bit ambitious in adding cabs & SiChrome flakes. (fingers crossed).
