---\n#### Daily Report in Document Format : Prajwal G\n\n---\n# 12. Soldering Prerequisites\n### Date : 28/03/2023 \n\n### AIM : \n#### To learn about the soldering equipment present in the lab, the solder, the soldering iron, soldering wick, flux, etc. Learn to use them and perform basic soldering on a perf board. \n\n### Materials Required : \n#### 1.\tSoldering Machine \n#### 2.\tSoldering Gun\n#### 3.\tSolder\n#### 4.\tLED bulb\n#### 5.\tPerf Board\n#### 6.\tSponge\n#### 7.\tSoldering Flux\n#### 8.\tSoldering Wick\n#### 9.\tSoldering Iron\n\n### Procedure : \n#### 1.\t First gather the necessary materials.\n#### 2.\t Heat the soldering iron to the appropriate temperature. Apply a small amount of flux to the joint to be soldered.\n#### 3.\t Place the tip of the soldering iron at the joint and apply a small amount of solder. The heat from the iron will melt the solder.\n#### 4.\t Allow the joint to cool and solidify before handling it. \n\n### Image(Reference) :\n
