The problem of copper foil conductive circuit breakage is usually caused by the circuit board being damaged by external force,This leads to disconnection of the conductive copper foil.This failure usually renders the circuit unable to conduct electricity.Today author from qihe smt pick and place machine sharing you with some tips about how to deal with the problems encountered when soldering the circuit board?<\/p>\n\n\n\n

When correcting this board problem, the
Please use a knife to scrape off the insulating varnish on the copper conductive copper foil at both ends of the breakpoint.
Pull a few thin copper wires out of the copper wire,
Twist them together and tin them once.
Then solder the wires to the conductive copper foil,
Finally cut off the remaining wires.<\/p>\n\n\n\n

The problem of pad falling is usually due to repeated soldering to a certain point during maintenance,
cause the pad to disconnect at the solder joint,
This then leads to problems with direct soldering.<\/p>\n\n\n\n

After stripping the pads,
First use a knife to scrape off the insulating varnish on the copper foil at the breakpoint,
Pull several thin copper wires from the copper wire, twist them together,
Then use the tin plate again.
Then cut one end and solder it on the conductive copper foil,
The other end is wrapped around the component pin,
Then solder.
Finally, cut off the remaining wires.

Desoldering issues lead to bad contacts and sparks,
The circuit board is burnt and charred,
This mainly occurs in areas of higher voltage.
Circuit boards are inherently non-conductive.
However, after the circuit is ignited due to poor contact or other reasons,
Sparks can burn circuit boards.
Cemented carbide can conduct electricity under high pressure,
Therefore, the high voltage fluctuation is not enough,
This then leads to failure of electronic equipment.<\/p>\n\n\n\n

When dealing with this issue,
Please use a knife to clean the burnt area first,
Then connect the components with wires,
Brush a layer of insulating paint on each welding point,
Or use insulating paper to block each solder joint.
At the same time, we must rule out the cause of the spark.<\/p>\n\n\n\u9605\u8bfb\u66f4\u591a\uff1aHow to deal with the problems encountered when soldering the circuit board?<\/span><\/a>\n\n\n
