raymarine CF card reader corrosion

hello,
first time posting here I think. but have been a member for a long time.

I have a C120 that (must have) had water ingress through the CF card door and into the unit, damaging only the CF card reader pins.

I took the unit apart and it works fine, but the pins are severely oxidised and unusable.

I found a replacement card reader unit assembly on ebay for an E series, as a 3rd party expert repairman confirmed to me that the assemblies were interchangeable, but it did not work, they are not only different shapes and sizes, but the pin assembly on the E series is moulded in place (this IS smart), and on the C series they are removable on a pin rail system (which makes them easy to replace but perhaps they let moisture through... who knows).

so I'm back to square one. does anyone know of a reliable source to get these?
I've started looking here https://www.digikey.com/products/en/...20flash&opti=1

thanks for any helpful input on this....

Re: raymarine CF card reader corrosion

Welcome to the forum.

The first step should to attempt cleaning the existing pins to restore normal operation.

A short hair / stiff solder brush w/ isopropyl alcohol should be used to attempt repair.

The removal of the existing connector would be a royal butt pain, even for a skilled solder technician using high-quality tools and materials.

Re: raymarine CF card reader corrosion

thanks for the suggestion, but some of the pins have corroded away completely.

they are not soldered into place, they slide out on a pin rail together. I am in search of a replacement pin rail assembly.

Re: raymarine CF card reader corrosion

How about posting an image?

Potentially the mating card is also damaged. Has that been determined to be good?

Try Pete Waterson at seacoast marine electronics in Oriental, North Carolina. I happen to know that he has a C 90 W for parts and it should be interchangeable with your unit.

Re: raymarine CF card reader corrosion

I'm very thankful that I don't have that specific issue, but I DO have an issue with the card reader.

The guy at Ray (who no longer support the C120, more later) who worked on my unit last time, Mike Deluca, suggested that our units had a receiver which could break, in my case, but because the base and the pins were intact, be hot-glued back in place. That's the situation now, but I too am having some issues with my plotter, along with having my primary chip go south on me a while back. Fortunately for where I am currently, the matching chip, of South America/Caribbean also includes the northern Bahamas, and covers the area leading to the entrance to Fort Pierce, our return entry.

However...

You're nowhere near the US if your location is correct. But Raymarine (well, Chuck Anderson, the moderator for their tech support forum, anyway) recommends (and I have used them to replace the screen):

"Seawire Marine" <seawiremarine@gmail.com>

A guy named Javier is the owner and very helpful. I don't know if he'd have a source for your pins, but it's worth an email to ask. Tell him I said hello and that I have some questions of my own for him...

Re: raymarine CF card reader corrosion

The link you provided didn't really show anything other than CF Card parts. However, Digikey is good but you also might try looking at Mouser.

Re: raymarine CF card reader corrosion

salt water ingress while the machine was outdoors and turned off corroded the pins and replacing them is simple. pins are the only thing I'm after.

the original card is trashed, but I have a new one. I borrowed pins from another machine and everything worked fine in my machine. luckily. so now I need pins!

Re: raymarine CF card reader corrosion

I may have an issue with my receiver/pin array which is much simpler than yours, so I have a technical question:

Are all the pins directed to soldered-in legs, like an old computer memory chip, and that's what I see on the facing row? That would assume a circuit board, with the solder on the other side for each leg? My pin array in the past somehow flexed or otherwise moved, and I can't imagine how, if each pin were soldered via a leg.

I've asked my tech if he had any source for more pin array blocks. I'll follow up if he has one.

Thanks for any intelligence you may provide.

Re: raymarine CF card reader corrosion

Thanks for the image.

Is this the type of part that is being sought?

If so, then the pin-to-pin spacing is required. I usually measure many, then divide by the quantity measured.

The total quantity is also required. A larger part may be cut down.

Re: raymarine CF card reader corrosion

Further researching has shown others repairing camera receivers using cut-off sewing needles pressed into the breach. No idea if that could cure your issue; have not yet heard back (just mailed) from my RM contact...

Re: raymarine CF card reader corrosion

With permission, here's the comment stream from my Raymarine tech guy, Mike DeLuca:

Hi Skip

Looking at the picture of the Processor PCB, looks like that little yellow cap has a bubble on the top of it, if this is so, that part as well as the first transistor right beside of it will have to be replaced on the PCB as well in order to get it to work again, even with a new Pin Matrix. If you think you have somebody there that can replace those parts I will see if I can come up with those for you as well. Not sure until I look as we no longer work on those units so parts are hard to come by.

and

Hi Skip

You will need a Pin Matrix to make that repair. I have a good used one that I could send you. You will also have to scrap off the surrounding area in which the new epoxy will be applied at the base of the pins. What I used to do in put the Pin Matrix in place, with a card to hold it steady and the apply the epoxy around the pins. I can give you a tube of this 5 min epoxy which should restore the card reader functions. If that will work for you, e-mail me the address.

Regards


The 'you' referred to is OP...

yes, this is exactly what I'm looking for, with one plastic holder (pin matrix?) holding all the 32 pins for a CF card. that is the only thing that is missing from the C120.

I have tested the unit with another set of pins and everything works. there is no ribbon cable or epoxy. this is specifically what I am looking for.
