Quite possibly the worst soldering job for the overhead compass display fix ever

So I got a little frustrated with trying to re-resolder the infamous "510" resistors that are known causes of the temp compass display failure. After about 30mins i gave up and called it a day. Reinstalled the display and didn't expect success but the end result shocked me and gave the giggles:

 

Looks like my welding......Oh well. It works. That's a positive.

 

Not bad

 

I'd declare victory and call it a day! Success!

 

The title should read:

Quite possibly the worst soldering job.... that works!

Its all about the end game, if it works it works.

 

As an IPC certified solder trainer and electrical engineer, I shake my head slowly with a look of slight disappointment on my face sir.

 

smd's are hard to solder when you are wearing mittens and using one of these...so...good job

 

Judgement from on high has spoken

I think you did a amazing job

 

Looks beer worthy to me.

 

Those resistors look huge, yet I'm amazed how you were able to achieve such results.... It looks as though you've done some drinking and installed these with blow torch and wearing a welding helmet for arc welding. I'm not sure how you would do with 0402 size resistors.

In the future with these big resistor...it's fairly easy to do... if you have a soldering iron, remove the resistors and then the excess solder from the pad. Next, I suggest you use tweeter and a small dot of glue on the bottom side of the resistor and place it onto the PCB. The dot of glue is to help the resistor stay on the PCB. Tiny dot. If you have the correct tip. Touch the tip to one end of the resistor for a 1 second or 2. While the tip is on the end of the resistor and pad...insert the solder wire to the tip and a little bit should melt onto the one side of the resistor and pad. You have one connection now...repeat on the opposite side.

 

Here is an action shot of those 510 resistors being soldered onto the board

 

As long as you didnt burn out the components and you have a solid connection that works... Great Job man. Those components arnt designed to be hand soldered so it makes it even better

 

The 107° concerns me more than the soldering. I have no desire to experience such temperatures.

 

So with me soldering with muffler welding tools along with several tall cool beverages from the garage fridge in extreme heat is a no-no ?

 

The bigger the glob, the better the job

 

educate me- is this result because the solder wasn't hot enough? not enough flux? thx

 

107 degrees outside I would've called it a day too

 

the original problem or the repair ?

for the repair, a number of factors.

you need a way to tack it in place (nail polish works) and a selection of fine tips

 

Looks to me like the flux burned off.

If you were to do it all over, I'd tin one pad with a generous dab of solder, then put a nice blob of no-clean flux on it (I like chipquik gel flux). Hold the resistor in tweezers with one hand, with the other, apply heat to the solder you placed on the board. Slide the resistor into the molten solder.

Then solder the other side (tin your tip, apply heat to resistor and pad simultaneously, feed solder into the joint until you get good wicking).

Then go back to your original side and either add flux and heat to reflow it, or bring in some fresh solder w/ flux to do the same.

You'd also want to look at better tools, most likely, if you were doing this often. A ratshak woodburner iron will screw you up even when you've got experience doing this sort of thing.
