You have 5 minutes to check the resistors you have done. ARE YOUR RESISTORS IN THE RIGHT ORDER? You have 5 minutes to check the resistors you have done. grey Bear in mind – this PCB is shown from the BACK.

Soldering Safety – Soldering Irons are very HOT! 1. When I am not using the soldering iron, I should return it to the holder. 5. I will not touch the soldering iron to see if it is on. Instead, test it on the wet sponge. 9. I can snip the excess wires off with wire clips once I am finished. 2 I will put a heat mat under the area I am working on. 6. I wear an apron and take off my blazer when soldering. If I do accidentally burn myself, I will RUN THE BURN UNDER THE COLD TAP FOR 10 MINUTES. 3. Good ventilation is important when soldering. 7. I will clean the iron between each join. 4. Only one person should solder at a time and they should concentrate well 8. I can use a crocodile clip between the board and my component to protect it from the heat.

Lesson Objectives: To continue to solder safely and effectively. Success Criteria Must: Have checked the resistors that you have added so far and continued to add resistors to the board in the correct places. Should: Have soldered the first six resistors in place safely and accurately. Could: Have completed the soldering task up to resistor 11. SOLDERING IRONS ARE DANGEROUS - ANYONE CAUGHT ACTING STUPIDLY WITH EQUIPMENT WILL AUTOMATICALLY BE GIVEN AN AFTER SCHOOL DETENTION.
