IC1 is a Surface Mount part, but it is large and easy to solder. Start
by wetting one pad with solder. Then place the part in position and
heat the lead so the solder below it melts and anchors the part.
The four other leads can then be soldered. Do not solder the
heatsink tab.
The leads of C1, C2 and the inductor L1 need to be bent as shown
below. The inductor is not polarized, but C1 and C2 are polarized
so note the positon of the pale stripe when bending the leads. This
will ensure the pale stripe matches up with the cross hatched
marking on the PCB.
