Hello,

My son had a portable dvd player. Just a cheap one and I know some
would say it will be quicker and easier to buy a new one but the
headphone socket stopped working.

I bought a new socket and removed the old one. I went to solder the
replacement in, only to find that there is no track to solder to at
one of the pins. I don't know if this is what caused the problem or
whether I damaged it during my soldering.

I have done some Googling and it seems you can do repairs but the part
has many names: some web sites call them "pass throughs" or
"passthroughs", other web sites call them "vias", others ""through
holes".

I have found international sellers selling these on ebay but no UK
sellers, so is there another name for these in the UK? Not knowing
what term to search for is half the problem.

Thanks,
Stephen.

Quite possibly it's a through-plated hole. Is there a track on the upper
side?

It is possible you've damaged the hole, or the track on the top surface-
it's simply a way of continuing the PCB track through the board to the
other side. There should at least be a small ring visible to solder to,
and the solder should flow through the hole.

I have done some Googling and it seems you can do repairs but the part
has many names: some web sites call them "pass throughs" or
"passthroughs", other web sites call them "vias", others ""through
holes".

It's pretty common for the unskilled to damage a PCB when removing a
component.

You'd normally repair the broken track(s) with suitable sized wire.
Fusewire is an easy source of this.

A schematic helps. You can then check continuity from the pins on the
socket to the next component.

When you say no track, is there evidence of any track? Boards that
take wire ended components are often plated through multi layer
boards, so no obvious track either side isn't always indicative of a
problem. Assuming you have a pad to solder the component to on one
side at least, go ahead, solder the socket in. If it does not work
then, just bin it. Any damage to a modern multi layer PCB isn't
practical to repair, unless of course its a surface track with an
obvious path.

No track, or no pad?

No track may not be a problem. If the board is double sided the track
may be on the top (and the hole through plated). If its multilayer, then
the track may not be visible from either top or bottom, as it could be
sandwiched in one of the inner layers.

Vias can also be tracks that are on inner layers of the board.

If you have damaged the through plating (unlikely), then with a double
sided board, you would just add a wire. With a multi layer board you
would need a schematic (or a working board and a multimeter) to work out
where to wire to.

They are intended to be used during the manufacture of the PCB, not as
a repair item. Just use a bit of tinned copped wire to link through the
board to the socket, then reinforce the socket to the PCB with some
Araldite.

You can't. Solder a bit of fine wire all the way through the hole & hope it works. It might.

The pad is the ring of PCB trace that encircles the pin - i.e. the bit
you solder the protruding leg to in the case of a through hole mounting
component.

So yes, the "ring" is the pad (for surface mount components, it will
just be a single flat exposed area of track rather than a ring since
there is no hole).

Are you sure it had ring originally? If so, its possible that you ripped
it off the board when desoldering the old component.

If that is the case, then you will need to find another way to make the
connection. If the ring connected to a visible track, then its quite
easy. Just scrape off the solder resist coating on the track and use a
bridge wire to the pin. If there is no track, is there one visible on
the other side of the board?

If there is no track visible on either side, and no pad on the top
surface that you can solder to, then you may still find that the through
hole plating is fine (and by extension the connection to any internal
PCB layers is likely ok as well). You can then use a multimeter on a low
ohms range to probe from the hole (stick a bit of wire through it - or
even just rely on the leg of the jack socket), and find a close point
that is connected to it. Then wire to that.

If it's the ground pin/s of the socket that can be wired to nearly any place that's connected to ground. If not you can also look up the usual circuits for the amplifier chip - in many cases you'll connect to one side of a biggish capacitor.

Again, picture.


NT

I'dhave thought a nice little high impedence crystal earpiece with wirs
could be used to detect the correct places if the track is broken. Often its
physical movement that cracks these tracks.
Be careful not to short tracks though.
As has been said most small devices use plated through double sided pcbs,
but it may well be that the track is only on the top side in this case. I
did encounter one some years back where the actual socket was held down by
melted plastic pins and the connections on the actual socket were flat for
surface mount pcbs. Either way often a bit of careful bodgery can get them
working.

That would typically detect 2 possible places, one of which will work, the other of which will fry things if connected to. It's usully possible to tell which is which by following the cap to the IC, and connecting to the non-IC side of the cap. Usually.

Are the pins of the new socket exactly the same as the old one? You say "no
track", which sounds as if it's a surface-mount socket, but bought sockets
usually have pins which go through holes in the board and soldered on the
other side. There may not be visible tracks connected to the holes if it's a
multi-layered board with inner tracks. Provided the hole has a visible ring
('pad') round it on top or bottom surface you should be all right if you
solder the pin to that.

You can't. Solder a bit of fine wire all the way through the hole & hope it works. It might.

Actually, under some circumstances you can - as long as there is at
least a bit of track left on one side. You can buy hollow pins with a
small flange at one end (I can't remember what they are called), which
are intended to be put into home etched pcbs, drilled with larger than
normal holes) to effectively make them through-hole plated.

OK for double sided but no use for multilayered. I assume the OP has the latter, otherwise there wouldn't be an issue to address. No picture has been forthcoming.

Multilayered boards normally use the sandwiched hidden layers for ground
plane connections (normally the zero volt and 5 volt power supply rails
in a classic 4 layer PC Motherboard) rather than for circuit traces which
normally occupy the top and bottom surface layers using through plated
holes either as 'vias' or connections to the zero volt and power supply
voltage(s) groundplanes.

Modern motherboards might well have 3 internal groundplanes (0v, +5v and
+3.3v) with the less commonly used +/-12v rails using surface tracks.
Less complex circuit boards may well manage with just one groundplane
(usually the 0v rail) or even none. With modern mass produced electronic
gadgets, the PCB can be the most expensive item in the BoM list,
especially more likely if it is a multilayer board with an internal
groundplane or three. Afaik, only military grade kit used internal layers
for signal connection traces.

For damaged through plated holes used for vias, it's usually reasonably
easy to effect a repair. When it comes to open circuit through plated
connections to an internal groundplane, you simply locate the nearest
handy component pin connected to the groundplane (0V, 5v or whatever) and
solder a wire strap to bridge the connection.

Soldering a wire strap from a handy 5 volt pin to the input tag on the
3.3v analogue regulators used to power 3.3v 80486 CPUs was a common
enough remedy to deal with fatigue stress cracking of the through plated
connection to the internal 5v groundplane induced by thermal cycling from
the heat of the regulator which itself was able to cope (but, contrary to
expectations, not the PCB it was mounted onto).
