3D printer driver chip assembly

stepstick drivers
Making this today.  

Driver chips for the 3D printer.  They arrive without the pins on them so they have to be assembled. 

Left is how the parts are aligned using a pre-drilled bread board.  Top are the parts, and bottom right is finished part.

The trick is using very fine silver solder wire and a lot of rosin core flux.  Of course the obvious steady hand and good eyesight are important too.
