Practice Making a PCB

Practice Making a PCB

This page contains a practice assignment for making a schematic and a pcb. Refer to the PCB_Artist tutorial for information on how to finish it.

We are going to make a leaky integrator schematic and pcb. You can read about leaky integrators here in the integrator section. This circuit will consist of 2 resistors, 1 capacitor and an op-amp (such as LT1001CN8).

Make the Schematic

We are going to make the following schematic.

You already have the resistor and capacitor components, but the op-amp component does not exist yet.

Search for a datasheet of the LT1001CN8 precision operational amplifier. (You can search on google, digikey...etc).

To create the component, you can either draw your own schematic for the 8pin op-amp as shown above OR you can find the existing schematic symbol under one of the existing libraries. If you make your own, make sure you have 8 pins.

You will have to make the pcb footprint for this op-amp using the tools from the tutorial.

Create a component and name the pins as shown in this schematic (ie IN-,IN+,etc)

You will need to add extra text for Vin and Vout.

Make the PCB

Now we will make the PCB of this circuit. To be sure we are on the same page, download the complete schematic [[Media:ME333_lab2_complete_schematic.sch] and incomplete PCB [[Media:ME333_lab2_incomplete_pcb.sch].

The finished board should look like this:

But it is missing some components? and traces? Fill them in.
