Step 4: Carefully solder each chip leg to the
SchmartBoard, by pushing the solder from the
outside of the groove to the chip leg; hold
iron by pad about 2-3 seconds.
You do not need to add any solder to this
step. Put the soldering iron tip in the first
electronic pad groove at the outside point of
the groove and push it forward until it
touches the chip leg. Do not put pressure in a
downward position; the solder will melt and
be pushed towards the leg. Do this in each
groove that has a leg.
Step 5: Repeat Steps 3 to 5 to solder the
EEPROM chip (U2) as you did the P8X32A
chip.
Step 6: Open the P8X32A SchmartBoard
Schematic.pdf; this will be a reference while
assembling.
Each of the parts that you will install from
here out will need the appropriate portions of
solder and flux; depending on the type of
solder you use will determine the heat needed
for the soldering iron; please see solder
package for details. The SchmartBoard uses
lead-free solder and is suggested as the type
to use.
