Certainly! Low wattage irons for small components. Larger wattage irons for larger components or big solder joints. Even better are combo solder - desolder units with adjustable temps or just solder units with adjustable temps. I've been repairing electronic devices for over 30 years as a hobby. Sigh - the components are getting smaller and my eyes are getting worse.
SMD devices can be difficult - I use a sticky agent - or for temp testing - tack solder one side to install/replace/test an SMD. Fortunately, SMD devices rarely fail though they may develop intermittent or cold-solder joints.
Multipin IC's can be difficult too. Troubleshooting is important in isolating the IC as the faulty component - unsoldering output, input, B+, ground, or associated RLC circuits (depends on what the IC does, circuitry, and symptoms) can help determine if IC is faulty. A schematic really helps, but I usually rely on replacement catalogs or experience for info.
J-wings are nearly impossible without specialized equipment.
I have some multiple-pin unsoldering attachments but there are many IC pinout configurations. I've repaired IC's with 64 or more leads, but never replaced one.
Good luck!
