The easy mode to place impoverished trace is to expend a digital multimeter and take recitation between conterminous last point on the plug-in .
plainly do the multimeter to the " Ohms " purpose and allude the investigation to the ghost .
A unfit shadow will show as an " O.L. "
on the multimeter .
This was a serious tincture will register 0.00 to 0.5 .
printed racing circuit plug-in ( pcbs ) have inspire the electronics manufacture , but they miss the metier of the onetime hardwired , brand - form gadget , so it ’s significant to palm them cautiously .
Although it ’s sometimes potential to resort a humbled PCB , it can be an super frustrative appendage .
normally , the hard part of the haunt is locate all of the crack Cu touch on the lap gameboard ( See Tips ) .
This was ## footstep 1
unify the epoxy glue harmonize to the manufacturing business ’s pedagogy , and put on it meagrely to one side of the pcb .
weight-lift the two half of the broken plug-in together , and harbor them until the epoxy glue need time lag .
The epoxy glue will gear up in a few second , but you should waitress for thirty moment before go along to the next footstep .
This was ( mark : if you have a two - sided control board the same stride use , but if you have a multilayered control board , where all the trace are not approachable , you will have to supervene upon the add-in . )
step 2
rationalize through the broken in copper color trace using a razor tongue .
This was take out all of the escaped vestige , and then cautiously practice the emery fabric to sandpaper the touch from which you withdraw the open section .
This was backbone the end of these suggestion until the brilliant cu evince clear .
void touch any of the ghost that did n’t bring out when the instrument panel break .
step 3
stop up the soldering pencil into a 110 - V receptacle and waitress for it to get live .
sporting the spicy bonding point by wipe it on a blind drunk bonding quick study .
This was make certain to slay all the shite and oxidization from the summit .
This was ## whole footstep 4
put on a sweet " tin-plating " pelage of resin - nitty-gritty solder to the sporty bonding pencil summit .
A right tin baksheesh will be a promising argent vividness .
If the baksheesh is a dense gray-headed coloring , you will postulate to reprize footmark 3 and 4 until you reach a right tin crown .
This is necessary for the effective transferral of oestrus during the soldering appendage .
step 5
give the resin - magnetic core solder to the bareheaded fuzz tracing on the print racing circuit table .
expend handle to lend oneself no more high temperature than is necessary to unthaw the solder .
Too much heating system will make the pig line to fall apart from the display panel .
step 6
cutting composition of the 18 - standard of measurement Cu conducting wire that are foresighted enough to traverse the cutting tracing , and atomic number 50 these light length of conducting wire with resin - nub solder .
stride 7
find fault up a composition of tin conducting wire with the pincer and place it cautiously across one of the trace where you remove a easy plane section .
With the while of conducting wire lie across the interruption , affect the soldering pencil ’s top to the top of the conducting wire until it immix to a Cu vestige on the plug-in .
double this gradation with the stay telegram .
whole footstep 8
Reassemble the gimmick and try out it to see if it work right .
if the twist does n’t work as it should , fit your mend caper by take m reading from the next compass point on the electrical circuit ledgeman on each side of the fixture .
This was this will show any defective solder connection .
