Hi Anyone know of a Surface mount holder where I can easily change out resistor and capacitors rather than to solder and desolder. Purpose is for testing different variations. Could like like something below without the cap being permanantly joined to the side bracket.

 

If the source of the picture does not sell them, make them. You will need tiny tweezers, cutters, benders and dexterity.

 

What do you want the holder to mount to? What size components need to be accommodated?

 

Can you prototype on a breadboard and then make the finished product on something else? Because breadboards allow you to easily change the configuration and value of components without soldering. The only downsides for testing things out are capacities and relatively low current ratings.
