The train is an important and even irreplaceable component of many mechanisms. In computers, loops are used to connect hard drives, optical drives and other nodes to the motherboard. A mobile phone will not work without a loop, because it connects its moving parts and serves to transmit a signal from one part of the mobile to another.
Instructions
Step 1
To glue the ribbon cable to the matrix, completely separate the damaged ribbon cable. Then rinse off the remnants of the conductive glue with which it was originally glued with acetone. Apply flux liberally to the board and ribbon and tinker with a soldering iron using a small mini-wave tip. It will collect excess solder on its surface, and there will be no closed contacts. Rinse off all flux. Small beads of solder should remain on the gold-plated contacts.
Step 2
Do this carefully to get uniform beads. Apply a little of the same flux, align the contacts on the board and the ribbon cable, and warm evenly with a thermal air. The solder will melt, the plume will float and, under the influence of the surface solder tension, will find its place by itself. In doing so, it softens and takes on an ideal flat contact surface.
Step 3
Use conductive glue to glue the ribbon cable to the tracks. You can buy such glue at any specialized electronics store or car stores.
Step 4
Fill the tracks with sealant - the result is almost the same as with glue, but in this case you cannot promise the same durability as in the case of special conductive adhesives.
Step 5
Press down on your own train using an elastic band from other indicators. If you have a toy "Wait a minute", use it - there these rubber bands are big and very helpful in such situations. You can also glue the wires from the wire to the indicator, and in turn glue them to the restored tracks of the loop itself.
Step 6
If the train on the calculator has come off, glue it by simply placing it on the contacts and ironing it through the paper. But it is better to practice on a penny calculator in order to "fill your hand" and not spoil everything. This method is more suitable for the repair of small office equipment, rather than computers and similar mechanisms.
