Super expensive Ferretti Yacht motherboard Repair - Urgent 3 hours service request.

[@nickh4309]

I'm a mechanic, we usually just get new or remanufactured modules. Never thought to send a board out for repairs. I'm so used to dealing with the manufacturer and aftermarket that it never crossed my mind. Some are very expensive. Might be worth having repaired. Not to mention that it can take weeks to aquire sometimes.

[@kaelin000]

the biggest issue with a lot of automotive electronics is the presence of potting compounds, conformal coatings (principally for environmental and anti-explosion concerns - keeping the weather out and fire in) and a host of anti-tamper measures generally making them a bear to work on. if you consider the labour required to curcumvent those, diagnose and repair the fault THEN return it to OE standards... is probably why you don't see a lot of refurbished ECU's about, particularly when there's the option of buying them from breakers. also, from experience trying to repair a potted/coated PCB is the stuff of nightmares, it's really hard work not to do more damage to the board and/or components just removing the stuff.

[@hippopotamus86]

This is how my brother became successful doing 1 man plant repairs. He could fix things in a couple of days that other service centers would take weeks to do.

[@talos86]

@@kaelin000 yep, the conformal coating is a big pain in the ass. Some boards are just dipped in simple varnish(Valeo/Aptive BSI boards), some are coated with silicone(Hirschmann boards in the BMW sharkfin antennas), but the new standard is epoxy resin. The new Valeo windshield wiper motor assys are filled with epoxy resin. The motor housing contains the relay and the electronic board for the timed wiping and the rain sensor. If the relay fails(which are usually do), then you need to replace the whole assembly with the perfectly fine motor and electronics.

Those Ferretti yachts cost around $1m a shot, so the owner can probably well afford a ‘super expedited service’ fee :-) The control panel incorporates a wireless link to a pendant controller for the engines and side thrusters which is worn on a lanyard around your neck, so the boat owner can reverse the craft into a tight mooring space while standing away from the helm.

I've repaired a similar output stage on a board for a nearby farmer's John Deere years ago. The cable leading to a solenoid next to the plow was just shorted to ground because of mechanical damage. The guy fixed the cable and I replaced the failed transistor and I also had to repair the PCB with a bypass wire. As I know, he's still using that tractor on his field. So I think the yacht owner will be also satisfied, as I think, there was a similar problem on the vehicle.

[@wendellknicely395]

When soldering tabs on the power supply, you must make sure that the TAB is fully soldered to the pad on the PCB. This both for conductivity and for heat transfer. A little dab of solder paste on the PAD should do the trick as capillary action can not be counted on with such heat slugs. Now about the engineer who designed the board. Those parts are severely under heat sinked for the size loads that the part is designed for. The engineer may have made the right calculations if the load may be significantly less than the part is capable of.

[@canonicaltom]

That's what the hot air tool was for. With the flux under the thermal pad, the solder would have wicked along the entire length of the metal interface.

[@jessicav2031]

I hope the customer orders genuine versions of those components from a reputable supplier to have on hand in case the knockoff ones fail, for the next repair. But they may not even know that ordering something with the same number from Ama*** is not the same as ordering it from Digikey/Mouser/whatever.

Pretty much all boat PCBs, even those in an enclosure. especially on a Feretti, are conformally coated. The last thing you want is to open the enclosure for service or whatever and have a drop of salt water land on the PCB.

I appreciate your technique of unsoldering components with low melt solder. I saw on "northridgefix" the product "Low Melt Solder Pack of 6 sticks". I would like to know its composition, because I can't find it in the product description. I am looking for one of the following material compositions: Alloy: Sn42/Bi58, Melting Point: 138C (281F) Alloy: Sn42/Bi57.6/Ag0.4, Melting Point: 138C (281F) Alloy: Sn42/Bi57/Ag1, Melting Point: 138C (281F) Alloy: Sn60/Bi40, Melting Point: 138-170C (281-338 F) Alloy: In52/Sn48, Melting Point: 118C (244F) Alloy: In66.3/Bi33.7, Melting Point: 72C (162 F) I am an electronics engineer and need these compositions for specific applications. Does the product sold have any of the alloys listed above?

I have seen those differing alloys, offered. Are they not designed for purpose, and then, you grab the closest non acid core, and get your job done?

Check digikey...

With all the damage on that board, why not do a diagnostic check on the other components as well?

[@rztrzt]

It's not what the customer wants, they specifically requested just the soldering.

[@robertpage2023]

@@rztrzt It's called, "Customer service". Your sort of service is what has become a sorry state of affairs these days.

[@rztrzt]

@@robertpage2023 You did not listen to what he said, the customer was very specific about only doing soldering and getting the board back asap.

@@robertpage2023 you wouldn't want to get too involved with the issue. hes just doing exactly what the customer asked him to do.. if northridge gets too involved the boat owner might try blaming him with any future problems relating to system that uses the board. its likely a $1,000,000+ boat.

[@robertpage2023]

@@sausagefingers714 Holy Crap..............I'm not saying that he should do any more work than asked to do but to simply take a look a the working order of the related components in the area of the damage to see if anything else was destroyed or not working. THEN, he can tell the customer what else he found. How is that going to come back to bite him in the rear??? How does putting meter probes on a component change anything? How does a simple diagnostic check make you "more involved"? I've seen him do it on many other boards after doing a repair to check out the potential other problems before reassembly and mailing off back to the customer and when he does find other problems he tells the customer before making the new repair. I would want such service.

obviously you know what you're doing, but when I was taught, I was told that a good joint is shiny and that a dull joint means it's cold. Is that right? He was doing avionics electrical stuff.

[@realistictruckers8208]

Cuando se excede la temperatura en la soldadura, se corre el riesgo de desprender las pistas del PCB, bien sea porque el soldador tiene una temperatura excesiva (demasiada potencia del soldador, para la potencia térmica que soportaría el circuito), o porque se mantiene la temperatura por mucho tiempo.

[@DrHarryT]

Those are the best jobs where the customer diagnosis the problem and even brings the parts. If it doesn't work, not your problem.

[@neverknowit11]

Very dicey! More power to you for doing this repair. I would have refused it. Any other failed components?

[@outfield1988]

Wonder what caused the meltdown of the components in the first place. Also did replacement of those components fix the problem I wonder.
