16. Colorado Space Grant Consortium Soldering 101 Class #06 Soldering 101 Class #06

17. Soldering:

19. Caution: - Soldering is dangerous if not respected - Be mindful of where you are and where the soldering iron is - Eyes and liquid solder - Everyone is expected to solder - If you get burned… - Stay together, don’t work ahead

20. Soldering Circuit Board Resistor Solder Pads Side View Top View PCB – printed circuit boards

21. RockOn! 2008 Prep Step 4: Tinning the iron -Tin the tip of the soldering iron by melting an inch or so of solder on the tip. -The iron will now look shiny on the tip. -Then wipe any excess solder on the golden sponge. -Now place the iron back into the holder. Tinning your soldering iron in this manner will aid in future soldering.

22. RockOn! 2008 Prep Step 4: Tinning the iron (close-up)

23. SolderingIron

24. Move soldering iron until tip is touching wire & solder pad

25. Move solder to touch edge of tip. Solder

26. Hold until solder melts on tip by wire Solder

27. Move solder back to touch wire only Solder

28. Move solder in to form a small pocket Solder

29. Move soldering iron tip up. This will drag solder up with it. Solder

30. Look for shinny fillets

31. RockOn! 2008 TIPS: -Use caution when clipping leads to avoid flinging metal across the room. -All soldering must achieve a good solder filet on the pad as shown for circuit reliability. -Also clip the leads in this fashion. -Bend resistors and diodes using your plastic tool as shown. Example of a good solder filet workmanship. nasa.gov

32. Soldering Tips 1.Make sure tip is hot 2.Clean & tin tip 3.Keep tip clean by using wet sponge and cloth 4.Heat until the parts are hot enough to melt solder 5.Hold until solder flashes around pad 6.Do not put too much solder on

33. Top View Tinned Copper Traces

34. Top View Soldered Solder bridge shorting two traces - bad, bad, bad But, can be fixed by reheating or using solder sucker
