Solder Wick
Solder wick is used to remove excess solder when a mistake is made.
Needle Nose Plyers
A small pair of needle nose pliers will aid in holding components to be soldered, as
well as the nuts affixing the LCD and uPAD.
Soldering
Prior soldering experience is preferable but not required to complete the uPAD Proto
Base. The recommended soldering temperature range is from 615˚ to 650˚. Routinely
clean and tin the tip of the iron when in use. Use of a metal mesh to clean the tip is
recommended over a wet sponge. Water both shocks the iron tip with a steep drop in
temperature, and it oxidizes the iron tip. When tinned the iron tip should merely be
coated lightly with solder.
Once the tip is prepared, the component leads must be prepared as well. For through-
hole soldering, components should be placed into the board. For components such as
resistors or capacitors bending of the leads as shown in Figure 1 will help to retain the
component for soldering.
Once in place, gently apply a small amount of flux between the solder pad and
component’s leads. Thereafter soldering can commence.
