It's significantly easier if you have grossly inadequate soldering equipment.
This is 2025, you can get properly temperature-controlled soldering irons for dirt cheap now.
- murderfs 2y agoTemperature control isn't usually the real problem, it's insufficient power to heat the board up to the liquidus temperature of the solder. This is an especially annoying pain in the ass when you're desoldering components from a board with non-thermal relief pads connected to gigantic copper pours, where you basically have to either use hot air or a board preheater.
- CarVac 2y agoI run a hobbyist open source hardware project that is user-assembled (PhobGCC) and even though our early boards had bad thermal relief a basic Pinecil is good enough to desolder SAC305 or SN99. But most of the issues with soldering came from people using uncontrolled irons that were either too hot, instantly burning off pads, or too cold thus not letting the flux punch through the oxides. When you get to big copper fills, SN63 helps, but ChipQuik helps more. So does a Thermaltronics TMT-1000S which is coming next month at $125. (love my TMT-2000S but the 1000S looks to be a steal)
