tricks to desolder?
 

i cant seem to get a couple holes desolder on my ecu... any tips or tricks?

Re: tricks to desolder?
 

Braid right?


Add more solder to get better heat transfer to the solder in the hole and use flux.

Re: tricks to desolder?
 

get an actual desoldering station :y makes life WAY easier.

or just learn how to position your braid correctly.

Re: tricks to desolder?
 

I also add solder to the two bastard holes, and then hit it w/ the braid again. Works well.

After awhile you will get better at using the braid, and the best way to position it.
I used to cut the chips out of OBD0's w/ a dremel. O0 Now I can get em' out clean w/ just the braid, and no ripped traces.

Re: tricks to desolder?
 

With the braid I like to insert the pin into the weave then lay my soldering tip on the braid. I also jump around on the chip so I don't over heat one section of the board. Just have some patience, play with it, and you'll get it...

Re: tricks to desolder?
 

I still use a dremel on pre chip ecu's have gotten a couple obd1 lately with them. Anywho also I like to do maybe 5-6 holes then let the iron rest for a little to get all that heat back works like a charm.


Just take your time ecu chipping is a bitch why everyone who starts doing it stops so bare with it

Re: tricks to desolder?
 

Not everyone. I make good money doing it, and that's just local. These have been paid for many, many, many times over. Gotta use pro products.

Having previous experience helps too. ;)

Same with manifold makers...only a few of the true blue stick around O0

Re: tricks to desolder?
 

I got a realy good soldering station(for electronics) and a manuel deolder sucker and also one te hooks up to air line and will suck the solder right out

Re: tricks to desolder?
 

That's right Chris. We are few that take pride and do a professional job.


From Solvent to Conformal Coat.

get it hot as ---- and use ur moms electrolux

Re: tricks to desolder?
 

I still do ecu's and basemaps all motor ones cause thats where majority of my experince is for a buddy of mine who does engine building for a living, so I do 2-3 a month. I have wanted to invest into a desoldering station but the 4 bucks for braid and the shack always calls me back.



Props to anyone that can spend a couple hours a day soldering. Funny cause I can spend hours porting and it really doesnt bother me but for most people they will have a loaded gun waiting.

Re: tricks to desolder?
 

Chris your business has grown alot in the last couple years for sure. Keep up the good work.

Re: tricks to desolder?
 

word I learned how to do soldering when I was around 10 years ols with rc cars. Mad skillllz. 17t motor owned the streets.

Re: tricks to desolder?
 

I wasn't that young when I learned how, sometime in middle school. Every RC car I had always needed repair. Battery wires and motor wires would always break off from the factory. New soldering and some hot glue fixed all problems

Re: tricks to desolder?
 

My dad is a electrical engineer so I got taught young the basics. I miss my rc10. I built an awd civic back in high school thing was wicked fast but on any turn it would flip. Always used electrical motors the 17t was a killer on top end for sure.

Re: tricks to desolder?
 

I far prefer using a solder sucker to using braid. I spend about 6-8hrs a day soldering at the moment. But i'm an electronic engineer.

Main tips, use a good quality iron. Use a solder sucker, if the hole doesn't come clean or you end up with a little bit of solder left in the hole add more solder until it forms a decent sized dome, then heat it up and try again.

If the solder won't flow, use liquid flux (this ---- will make you cough your lungs up).

Takes me 20 mins to chip an ecu, i earn $60 for each chipping job i do. Plus IAB conversions earn me $50-100

For pre-chipped ecu's i use side cutters to cut through the legs, then tweezers to pull the pins from the heated solder. Takes another 5 mins max. Seriously, you struggle with crappy through hole components? I have to solder 0603 package surface mount in work.

Sucker bulb. :y

Re: tricks to desolder?
 

Thanks, it's very nice to be able to do what I love on a day to day basis and for that I feel privileged.

Doing solder work is very calming to me. When I had my day job I could come home and sit there for a few hours and bang out a couple ECUs with the sucker and braid. Darkness turned into light when I bought my first desolder station, wow...what a difference. Cleaner and easier...for me it made sense. Probably close to 1000 ECUs now it well paid for itself, I actually bought a 2nd station a while back :)

Re: tricks to desolder?
 

I use the $10 dollar desoldering iron from radio shack it has a sucker ball on it like people use to suck snot out of babies noses. it works great it just gets to hot sometimes and you have to unplug it.

Re: tricks to desolder?
 

I was never really in to using braid on circuit boards. I had a weller desoldering gun for years, until I started doing ecu's. Then it just made sense to get something more professional. PLUS the weller used really expensive collection tubes and tips.

What equipment do you use, Chris?

Re: tricks to desolder?
 

Pretty much the same for me. If I did any volume like Chris or others do I would invest in something better obviously.

Re: tricks to desolder?
 

Remember that time I had you chip an ecu for me because I thought my soldering was bad. And then after I got the ecu back that you chipped for me and I still had a solid cell. Then you figured out I had my chip addresses screwed up the whole time!!! that sucked I wasted a good ecu desloderiing and soldering on the board ,the first one I ever did thinking I couldn't solder.

remember kids start in hex 08000 and end in hex 0FFFF for a 27sf512 :1

Re: tricks to desolder?
 

u can cut a sucker bulb in half and duct tape it to a vacuum cleaner hose, bam... hmt solder sucker...

Re: tricks to desolder?
 

Hakko 808 FTMFW!!!! but thats just how i roll

Re: tricks to desolder?
 

Damn skippy.

is that the ones you guys are rocking. Maybe its time for me to get out of the dark ages and spend a couple bucks. I ------ hate braid. It does the job but it gets old

Re: tricks to desolder?
 

yeah thats the one, can desolder a board in less then 5 minutes

Re: tricks to desolder?
 

Yup, check around though. That price is way too high. I got mine locally at Fry's for $119 on sale. That was about three years ago though, but I think Hakko lists them for $159.

Also make sure it comes with the case. The case is very nice, yes yes. I've seen some places that sell them without it.

Re: tricks to desolder?
 

fry's has them listed at 159. Hell Ive spent hundreds on braid :1

Re: tricks to desolder?
 

Don't get me wrong, braid definitely has it's purpose, just not on circuit boards. When I do terminals and larger stuff, it's braid all the way. Braid can soak up massive amounts of solder and do a very clean job if done correctly.

Just shop around or wait for a sale if you can.

Re: tricks to desolder?
 

i would get one of those guns forsure if i had to do this more then once and a while. i use both braid and a spring loaded radio shack suckr thing, niether work great.

also a trick my friend showed me i still use too, heat the holes and blow them out with a straw, works good but somtimes it leaves "tails" of solder on the back side u have to get off

Re: tricks to desolder?
 

You should get that deslodering iron from radioshack. it works good alot fast then braid.

Re: tricks to desolder?
 

now ... what to clean the board with ... thanks!

Re: tricks to desolder?
 

I use 800-1000 grit sandpaper real lightly then a strong tooth brush. then I wash the board with dish liquid and water. then let it dry until the next day.

Re: tricks to desolder?
 

----, for that price it'd be stupid for me not to get one, I too have spent hundreds on braid...

Re: tricks to desolder?
 

I clean pcb's with either isopropanol alcohol or flux cleaner, i have both at my disposal from work.
