Automotive electronics repair on Ford F150 ECU fixing broken traces after capacitors leaked on pcb

[@toomanyprojectstx]

One of the BEST trace repair videos ive ever seen on YT. You are a BOSS at repairing these. Great job!

[@ecurepair]

Thank you, Glad you liked it!

The Trace repair was excellent. Well done and appreciate your skill and experience to do this.

[@ecurepair]

Thank you, It has been awhile since I had seen one of these. Always enjoy these older (and simpler) ecu's for some reason.

Serious circuit board restoration and repair! Well done! Outstanding video!

[@ecurepair]

Thank you, Glad you liked it!

Seems so simple but it's not. I wonder if the little traces or leads can arc between each other if too close? What is the minimum distance. Some of the repairs I see on boards like this look wavy and on the edge of touching. It's hard to fathom the confidence to stick a soldering iron against this board. You'd think it would melt more that intended. Wow 👏🏼

[@ecurepair]

That's a good question, for IPC Class 2 the standard recommendation for minimum trace-to-trace spacing is 0.25mm (10 mil) for low voltage & 0.5mm (20 mil) for high voltage. I also covered everything with a nice silicone conformal coating after which helps ensure no moisture or vibrations causes issues later on.

Glad you enjoyed it! Thanks for watching.

since you were working on Ford EE4 system I was hoping for some guidance. 1995 Ford E350 7.5 litre. 3 KOEO Codes 558 EGR Control Solenoid Short to Voltage or Ground 629 Torque Converter Clutch Circuit fault 626 Coast Clutch circuit fault. I have ckd power ground and solenoid resistance all are ok. Codes appeared after a grounding lead from an old snap on counselor was connected to coil negative for cylinder balance shorting. This solenoid has its own diode. When I got the vehicle the solenoid was shorted. A new one was installed. The transmission circuits for #2&3 codes are not connected to anything else so I don't see how they would be related. My normal repair guys looked at it twice and find no faults on the board. I would be happy to pay to get it fixed but want to have some hope it is the box. The 558 ALWAYS pops up on Key On Engine Off test without interaction with EGR valve position sensor Any ideas would be greatly appreciated. TY Gus

What year truck was this from?

[@ecurepair]

early-mid 90's

[@davidtrujillo192]

What year was that f150?

[@ecurepair]

Dont remember sorry. Its pretty much same for all pre-95 ecu's.

[@mbrunker5167]

What kind of tools and supplies did you use?

[@ecurepair]

The list is way too long. Once in awhile I'll post what I used in the description. This video looks like I was using amtec flux, rel22 solder, metcal solder station, quick hot air.

[@sergeyt8514]

Do you repair a 2010 f150 body control module?

[@ecurepair]

Ive worked on them sure. What issues is it having?

[@dakotasimpson4993]

Would you do one for someone if they paid for you to repair?

[@ecurepair]

I do. www.keyworks.us

[@jaydenfischer9727]

Are all automotive boards 5volt?

[@ecurepair]

5v logic circuits is most common (especially on older modules) but they use 3v a lot as well so it just depends on what it is.

I'm afraid my 1990 mustang ECM is having a problem. Please send your contact info if you're interested in fixing it. Thanks

[@ecurepair]

you can find my contact info in my profile or by visiting my site. links are in my video descriptions.
