FAIL THREAD!!!!

If the tip won't take solder, then it won't solder! You can use a file or a scotchbrite pad to clean the tip to get 1-2 solder joints BUT you need to do them quick, the tip will oxidize very quickly after you scrape the coating off and then won't solder anymore. But, once again, you can clean it with the scotchbrite or file for another couple of quick joints. I've used some quality irons, and some dollar store stuff, each will get the job done, but you need a clean tip!

You can add solder to remove solder in some instances, if the tip is clean and the temperature is right you should be able to keep a ball of solder on the tip. When you pull the iron away (fairly slowly, no jerky stuff!) it will pull the ball of solder with it and leave only what is needed on the joint.

You should never really need to grind or cut any excess solder away, that can all be done with an iron.
 





There are a lot of failures lurking on the forum. :crackup::crackup::crackup: What do you expect?
 
Lol I think I have started 2 of LPF's longest threads then rofl. The 6x GB thread and this one.

TO Commemorateify THIS FAILS, I SHALL CONTRIBUTE.

just another fail (AAARGH) :p

5500 was supposed to be a very low dropout linear regulator ..... at least seeing the datasheets ..... but this damn thing have an independent self-limiting circuitry inside, that make it not working at all in current mode ..... it's the 8th different one, that promise so much on datasheets, and then fail on practical tests ..... i start to feel myself a bit frustrated :p (but still fighting :eg:)

Pwnt.
 
I would like updates on this low dropout driver, should it ever work :D

No, unfortunately not ..... they have a self-limiter inside, that is not mentioned in the datasheets, that not only prevent you to go over 5V of output, but also decrease the Vout when the Iout increase in nonlinear mode ..... so, they works for a maximum of 150/170mA in current mode, but this also depend from the difference from Vin and Vout (sorta of "self-dissipation" limiter, not related to the chip temperature) ..... when i try to ask more than 170mA from them, the IC quickly drop the Vout (NOT stabilizing it, dropping it drastically), so, increasing the Vin, the Vout DECREASE proportionally, after that point, til the current reach 90/95mA ..... i've tried 2 different configurations, with it, but none of them works, and also, having the VREF internally referred to the ground (also this was not mentioned in the datasheet), trying to use it in the "free current limiter" configuration like an LM317 simply don't work ..... the only decent results i had til now, was with the 3080 .....

Ah, well, patience ..... the world is a place filled of delusions, after all ..... :p :D
