Hi guys! This is Rob with Gold Plating Services and we've got a pretty
interesting video for you here today.
This is our PCB repair kit
or printed circuit board repair kit.
It can be used for lots of things but that's its main purpose.
We have here some printed circuit boards that need repairing
We have a Dremel that's a side accessory not included with the kit but
is very important in this particular project.
and that's about it we got our
24k pen gold down in there with an ultrafine pen cleaning tip and the kit
voltage is set to 5 volts.
We're just going to get right to it.
What we're going to be doing is a lot of.. a lot of printed circuit board have this problem
where their solder contamination.
And what that is I'm going to show you here.
The solder contamination is this area here of solder that's on top of the gold plating.
That causes problems for the functionality of the printed circuit board.
So what we're going to be doing is abrasively removing the extra
solder there,
using the Dremel and this green tip that's a polishing tip.
Terry: We call it a pin plater. Rob: A pin polishing tip.
You can get the green polishing tips from us.
The Dremel you can acquire really at any hardware store
or craft store.
And as you see it's just polishing off that
excess unnecessary solder.
Which in turn is also removing the gold-plating that was intact to begin with.
That's okay because we're going to be re gold-plating it and it makes
something like this as good as new after you're done.
He's going ahead and removing even more gold than necessary
because as you'll see in a minute
replacing the gold on the area is a really quick and simple process.
And sometimes it's just better to start with a clean, fresh
non gold plated substrate.
While he's doing this polishing part, I'm just going to talk a little bit about Pen Gold.
The pen gold solution is a cobalt hardened 24 karat pen gold.
It's super high concentrated. It's four times more concentrated than our brush gold.
And so it applies very quickly
and in very concentrated areas. It's a great solution.
Now he's going to wipe off the excess polishing compound and any debris
now with just some Methanol-alcohol . Nothing too fancy.
And as you can see the
area there has
has really polished up.
You think there's more to remove?
Terry: Let me hit it again.
Looks like there's maybe a little bit more on there.
Alright.
Now it just looks like...
That was a pretty thick wall on there
You think it's all off of there now, Terry?
Terry: It's off good enough, i think.
I don't know what those little divots are.
It may be damaged from the solder.
Yeah, it might be damaged to the Nickel.
I can see that I'm beginning, on the the far edge, to begin to
get down through the Nickel so I probably shouldn't do any more.
Okay, go ahead and do the gold plating.
Now we're at five volts.
This is a stainless steel probe i'm making contact with.
As you see the gold goes on, goes on right away.
This super high concentrated gold it packs on the gold really quick.
That probe is about five inches long he's just got the alligator clip
attached to the back of it and that plugs into the common on the machine.
I'll show you in a minute here how the
how its wired up. It's really quite simple.
So as you see I mean the.. on a board like that.. to replace for
a company to replace or they have hundreds of these and the only thing
wrong with them is that little tiny bit of solder contamination.
You know here in five minutes, we've already repaired it.
You get in a rhythm of it you have somebody doing it and you can really,
really pump them out quick and it's a very valuable process to have access to.
Terry: Yeah, if we had hundreds of these to do we would have some people doing the polishing and some
people doing the plating.
So it would be a continuous flow.
Rob: And you could get them done real quick.
Terry: A little water to rinse.
Rob: Look at that.
This is nothing ever happened to that area, it's a
little bit shiny is all but
everywhere is gold again and that contact will now be
a usable contact.
That's it for that part I'm just going to real quickly show you how we were hooked up.
Coming off the PCB repair kit you have your
common lead and that is what clips up to this alligator clip.
And that's the probe you can really touch
really find specific areas with this probe it's needle sharp.
and then the red output port back here is the only other one
that comes to your combination handle.
that you can put the fine select plating
tips in there or the brush plating, which is that there.
That allows you to do bigger items.
And that's it. The PCB kits really quite straightforward.
Terry: Do you want to show how we would make the change?
Rob: Oh yeah, let's show that real quick. Here's how you pull the pen tip out.
This is how you put the stainless steel anode in and you tighten the thumbscrew
to tighten it in there.
And that's it.
Now you're brush plating.
Alright guys, well i hope that was informative and helpful for you.
And that's how you repair a printed circuit board
that has solder damaged with our PCB repair kit and a Dremel.
Thanks for watching!
