De-soldering pump: Prime the pump, release to vacuum up liquid solder. Only $5 to $12, but requires cleaning. Solder wick: Finely braided 18 to 42 AWG copper wire coated with rosin flux, “absorb” solder. Rolls start at $5. De-soldering station: Hot air pump, also called a rework station. Expensive, $150 to more than $1000. 10  Desoldering Tools De-soldering pump Solder Wick De-soldering station Image source: https://www.banzaimusic.com/image.php?id=4859&type=D Image source: http://electronicsisfun.in/wp-content/uploads/2017/02/solder-wix.png Image source: https://widaco.net/shop-2/hand-soldering/desoldering/desoldering-station/wr-2000d-weller-widaco/ 11 All-in-One Workstations Image source: https://paceworldwide.com/mbt250-sd-soldering-desoldering-rework-system 12 PCB Stand & Bench-top Vise Helping “Third Hand” holds the PCB securely in place Useful during soldering and inspections Image source: https://makeradvisor.com/best-adjustable-circuit-board-holder-pcb-clamp/ Image source: https://s-media-cache-ak0.pinimg.com/736x/30/7e/a5/307ea5f3c614670bb2370521ae8a2bc0.jpg 13  Solderless Breadboards Construction base for reusable prototyping of electronics A perforated plastic cover hides a special pattern of metallic strips underneath. Component leads and wires are inserted into specific holes to create simple circuits.
