Best solder station / vacuum desolder tool you can afford (eg Metcal and others). Normal 60/40 solder ( the eco friendly stuff will cause your hair to go grey), SMD flux stick, Fibreglass brush to remove solder resist, and if your into serious work, conformal coatings, isopropyl alcohol and toothbrush / cotton balls.
Hot air gun to pre-heat connections on large components.
30 Gauge insulated wire (to remake broken tracks or wire in mods)
DMM, with continuity beep, multiple test leads with sharp pin ends, alligator spring clip ends and SMD tweezer.
CRO over 100Mhz with 2 or more channels, and ideally with I2C, RS232, CAN protocol analysis / trigger abilities..
PSU with adjustable volts and current limits
FET/BJT/SCR component tester, great to confirm pinouts when building, and confirming go/nogo of suspect devices and LED testing. (never to be used on GaAs FETS).
SIG GEN / Function Gen for audio and RF, again, the best you can afford.
Old 10w HF rig (to listen and talk to equipment under test)
FLIR camera to identify that component hot spot and excess current issue, noting basic ones can be found under $300.
Conductive rubber mat to avoid scratching equipment, noting caution if working on gear that has more than 100v floating around.
hand tools, precision screwdrivers, long socket sets (5.5mm, 6mm, 7mm and up), alignment tools, power drill (for 2mm - 32mm drill bits/cutters), PCB drill for 0.3mm - 1.4mm drill bits.
** Your AC power outlet MUST have RCD / RCBO or earth leakage protection fitted, just to protect yourself.
Some ideas, David VK2CZ
