HOME REPAIR PCB?

Guest
I have a panasonic speaker phone KX-TC1740. The base unit had an
accidental heavy impact and the phone stopped working. I opened the
unit and on inspection with bare eyes, found a thin crack in the PCB
(looks like it is the only crack, but I am not sure)Is there any home
repair that I could try? I can see where the circuit lines are broken
- can I use a conducting glue or paint or something?
 
You can try scraping the traces near the crack to expose the copper , then
solder bridge using strands of extension cord wire . The only thing is that
when it cracked , it might have destroyed 1 or more componets .

No. Any decent PCB repair of the nature you describe requires the
correct soldering tools, and the skill to use them. A good soldering
station, suitable for fine PCB work, is a significant investment (at
least $130, usually a little more).

Another thing to consider: If that's more than a two-layer circuit
board (many are four, and those in more complex devices can range from
six to eight), the unit is pretty much history, as you'd never be able
to repair the inner-layer traces without a schematic diagram, board
layout, and a LOT of work (more than the unit's worth for sure).

Good luck.

Additional: the use of some type of magnifying device to check for
additional separated traces and damaged components. IMHO Get a small pen
type soldering iron from Rat Shack and have at it. Worse case scenario is
that you will have to buy another phone.

If it is a single layer PCB Scrap the broken track and repair with Solder
Cement from local Radio Shack etc
Unless you have a Soldering Iron.
I find this group to be one of the most negative. I try and get Advice from

Hi,
I can see circuits on the top and bottom of the board. How can I find
out if there are additional layers ?
Thanks.
