A microcircuit is an electronic circuit that sits on a plate made of a semiconductor material, usually silicon. Typically, the area of a typical integrated circuit is 1.5 mm2 and the thickness is 0.2 millimeters. All elements of the circuit (resistors, diodes, transistors, resistances and wiring connecting them) are placed on the plate.
Necessary
- - soldering iron;
- - plastic;
- - wires.
Instructions
Step 1
Use a special application to think over the design of the microcircuit. You can practice IC engineering using the Logisim program. You can download the application from the link
Step 2
Install the Electric VLSI application to complete the final circuit design with layers of conductors, dielectrics, and semiconductors. You can download it on the official website of the manufacturer https://www.staticfreesoft.com/productsFree.html. After you have managed to draw up an electronic design of the microcircuit, start creating it.
Step 3
Take a piece of plastic, it should be the size of your phone's SIM card. Purchase a conductive pencil from a radio store, which is designed to restore tracks. Take a conductive adhesive such as Kontaktol and a syringe.
Step 4
Find a metal box for the microcircuit case. Also look for a small amount of thin wires for discrete components.
Step 5
Start designing the microcircuit. Draw on the plate the conductive paths, resistors and capacitances, everything that can be drawn according to the constructed diagram on the computer. Next, glue the transistors or diodes. Glue the output wires of the microcircuit to the plate. It is best to pierce the plastic so that all pins move to the bottom of the board. Glue the lid on top, write the name on it.
Step 6
Solder the resulting microcircuit to the board. To do this, glue it with leads on a piece of self-adhesive aluminum foil, solder a thin wire to each leg. Use LTI-120 flux to solder the microcircuit. Make a board from fiberglass, place a circuit on it, form and solder the outputs to the board pads. Then take alcohol, wash the board from the flux residues. Next, solder the attachments.
