A schematic diagram is a fundamental two-dimensional circuit representation showing the functionality and connectivity between different electrical components. It is vital for a PCB designer to get familiarized with the schematic symbols that represent the components on a schematic diagram.

IEC 60617: The International Electrotechnical Commission (IEC) has issued this standard. It is based on the older standard, British Standard (BS 3939). This database includes over 1750 schematic symbols.

The schematic diagram should provide this additional information to ensure that appropriate components are selected. The resistor should have its resistance value expressed in ohms(). The battery should state its potential difference (voltage) expressed in volts. Other components are described in different terms. For example, capacitors are differentiated by their capacitance value expressed in farads (F), inductors are differentiated by their inductance value expressed in Henrys (H).

The values of attributes can vary from very small to extremely large units. To avoid filling circuit diagrams with long repeating strings of zeros for values like 1,000,000,000 or .0000000001, we use the International System of units for values (SI).

A wiring diagram is a generalized pictorial representation of an electrical circuit. The components are represented using simplified shapes in wiring diagrams. Wiring diagrams generally give detailed information about the relative location and arrangement of devices.

To understand a PCB schematic, it is essential for us to learn how the components on the schematic are connected. It contains information about various components and the operating conditions of the circuit.

The schematic is a drawing that defines the logical connections between components on a circuit board whether it is a rigid PCB or a flex board. It basically shows you how the components are electrically connected. A schematic contains a netlist which is a simple data structure that lists every connection in the design, as specified by the drawing. The below image shows an example of a schematic diagram.

If a design uses a hierarchical schematic, where numerous functional diagrams are interrelated with each other, then it defines the relationship between groups of components in different schematic diagrams.

Pin numbering: Pins define the connection points on the component for the incoming and outgoing signals. Pin numbering is made to ensure the connections shown in the schematic end up connected properly by copper on the PCB.

Schematic diagrams primarily consist of component symbols and the lines that represent the connection between the components. Understanding the schematic diagram is very important for designers in order to design a successful PCB.

The most fundamental of circuit components and symbols! Resistors on a schematic are usually represented by a few zig-zag lines, with two terminals extending outward. Schematics using international symbols may instead use a featureless rectangle, instead of the squiggles.

Sometimes -- on really busy schematics especially -- you can assign special symbols to node voltages. You can connect devices to these one-terminal symbols, and it'll be tied directly to 5V, 3.3V, VCC, or GND (ground). Positive voltage nodes are usually indicated by an arrow pointing up, while ground nodes usually involve one to three flat lines (or sometimes a down-pointing arrow or triangle).

No doubt, there are many circuit symbols left off this list, but those above should have you 90% literate in schematic reading. In general, symbols should share a fair amount in common with the real-life components they model. In addition to the symbol, each component on a schematic should have a unique name and value, which further helps to identify it.

One of the biggest keys to being schematic-literate is being able to recognize which components are which. The component symbols tell half the story, but each symbol should be paired with both a name and value to complete it.

Values help define exactly what a component is. For schematic components like resistors, capacitors, and inductors the value tells us how many ohms, farads, or henries they have. For other components, like integrated circuits, the value may just be the name of the chip. Crystals might list their oscillating frequency as their value. Basically, the value of a schematic component calls out its most important characteristic.

Component names are usually a combination of one or two letters and a number. The letter part of the name identifies the type of component -- R's for resistors, C's for capacitors, U's for integrated circuits, etc. Each component name on a schematic should be unique; if you have multiple resistors in a circuit, for example, they should be named R1, R2, R3, etc. Component names help us reference specific points in schematics.

Schematic nets tell you how components are wired together in a circuit. Nets are represented as lines between component terminals. Sometimes (but not always) they're a unique color, like the green lines in this schematic:

Wires can connect two terminals together, or they can connect dozens. When a wire splits into two directions, it creates a junction. We represent junctions on schematics with nodes, little dots placed at the intersection of the wires.

Nodes give us a way to say that "wires crossing this junction are connected". The absences of a node at a junction means two separate wires are just passing by, not forming any sort of connection. (When designing schematics, it's usually good practice to avoid these non-connected overlaps wherever possible, but sometimes it's unavoidable).

Sometimes, to make schematics more legible, we'll give a net a name and label it, rather than routing a wire all over the schematic. Nets with the same name are assumed to be connected, even though there isn't a visible wire connecting them. Names can either be written directly on top of the net, or they can be "tags", hanging off the wire.

Each net with the same name is connected, as in this schematic for an FT231X Breakout Board. Names and labels help keep schematics from getting too chaotic (imagine if all those nets were actually connected with wires).

Truly expansive schematics should be split into functional blocks. There might be a section for power input and voltage regulation, or a microcontroller section, or a section devoted to connectors. Try recognizing which sections are which, and following the flow of circuit from input to output. Really good schematic designers might even lay the circuit out like a book, inputs on the left side, outputs on the right.

Voltage nodes are single-terminal schematic components, which we can connect component terminals to in order to assign them to a specific voltage level. These are a special application of net names, meaning all terminals connected to a like-named voltage node are connected together.

If there's something on a schematic that just doesn't make sense, try finding a datasheet for the most important component. Usually the component doing the most work on a circuit is an integrated circuit, like a microcontroller or sensor. These are usually the largest component, oft-located at the center of the schematic.

That's all there is to schematic reading! Knowing component symbols, following nets, and identifying common labels. Understanding how a schematic works opens up the whole world of electronics to you! Check out some of these tutorial, to practice your new-found schematic knowledge:

The problem is I can't get arcpy to add the diagram layer to the map. I run arcpy.schematics.CreateDiagram to create the diagram and that works, but when I try to use arcpy.mapping.AddLayer to add the return from the diagram it throws an AssertionError. I have also tried to use arcpy.mapping.Layer but that throws the same error.

I had to deal with the same requirement and I ended up to convert the diagram to features which results in feature classes in a feature dataset. You can easily add these feature classes to the MXD then. You need a template-MXD with the correct symbology for all layers, because the symbology is lost when converting the diagrams to features. You can then programatically switch the data sources from the template-MXD to point to the converted feature classes.

I'm going to implement the idea you mentioned above. I'm going to export my schematic to a temporary geodatabase and use that to create a grid on top of, generate my pdf series for that schematic #with Data Driven pages, then move on to the next schematic.

Nice things I get from this are all of the feature classes and schematic diagrams continue to exist after the bulk process. You could open or update them individually if you wanted to make a one off. You could let this data structure live forever and next time through just update instead of create everything from scratch. I haven't saved out individual mxd files yet after repointing the data, but that could be done. This process is being used to automate generating 900-1000 diagrams.

Explanation and purpose of being able to do so:

There have been situations presented on this forum where people have wanted either multiple individual PCBs or be able to have multiple PCBs on the same panel. The panel layout would be provisioned with V-grooves or mouse bites and routed slots in order to break the panel apart into individual boards. ff782bc1db
