I think it was good and serviceable lap joint, but I could have done a better job with stripping the wires to the same size so there was no copper wire exposed at the end of the lap joint the instructor told me the same thing, but also to hold the two wires closer together so there is no gap between the two wires. I think my PCB board was serviceable again. I would like to use less solder next time because there was ball for one of them in the back side, but again I don’t think it would have made a big difference. Professor Rose gave me good tip and trick in figuring out if. He said if you run your fingernail through the end of soldering and if it gets caught then it is too much.

Venky’s 101 Guide to make a serviceable lap joint
Get the following tools to make you life easier. Trust me if I can’t do it without these tools there is no way you can.
1) Strip two wires to the same size
2) Using the soldering iron and soldering wick tin the stripped wires
3) Place each wire in the helping so the two tinned wire over lap each other and solder them together. You might need to add some extra solder, but not all the time.
4) Your finished product should like the following picture (it might looker better. This is normal. For some reason it looks worse that the one below I recommended that you start over)
Venky’s 101 Guide to make a PCB joint
Get the following tools to make you life easier. Trust me if I can’t do it without these tools there is no way you can.
1) Insert the resistors though the PCB board
2) Using the soldering iron heat up the hole so the solders flows though it all
3) Apply solder wick until you have enough
4) You want enough so it makes a volcano shape and there is just the right amount of solder
