Knowing the Electrical Considerations

pcb layout

The first step before embarking on designing a printed circuit board entails comprehending the electrical limits or parameters of your system. It should include voltages, current maximums, capacitance limitations, signal types, and shielding considerations. Besides a comprehensive net wire schematic and listing, other parameters should entail impedance attributes, location, and type of circuit connectors and components.

Developing the Schematic

It is a crucial step and entails developing the electrical-level design of your PCB board’s function and purpose. Remember, at this point, the mechanical representation has not set in yet.

Deploying a Schematic Capture Program or Tool in Developing the PCB Layout

In most instances, a suitable PCB provider like RayMing PCB and Assembly will collaborate with you or principal engineers in developing a schematic. Software platforms like Allegro, Altium, Mentor PADS become instrumental in demonstrating the functionality of the board. It also depicts the locations of electronic components such as transistors. After creating the schematic, it becomes prudent for the engineer (mechanical) to load and determine how well the PCB design will fit into the targeted application device.

Designing the PCB Stack-Up

It is an important consideration early on during the design phase due to the potential impedance. Impedance means the extent and how fast electricity can flow or travel down a copper trace. Stack-ups always play a pivotal role in determining how the engineer designs and fits the printed circuit board into the electronic device.

Defining Design Rules and Needs

The process step gets primarily defined by the acceptability criteria and standards of the IPC. IPC is instrumental in regulating quality standards in the PCB and electronics industry, especially when it comes to manufacturing. Such standards detail everything needed to understand the manufacturing of printed circuit boards. It is, however, always important to get a PCB layout company capable and familiar with such standards (IPC). It helps when it comes to averting project delays or major PCB project revisions.

Placing Electronic Components

It represents a collaborative stage. The PCB provider and the customer discuss the design besides the layout guidelines for component placement. For instance, the available standards or stipulations may indicate the non-viability of having specific components located near each other because of electrical noise generation in the circuit. The PCB solution provider will, in most instances, have the relevant data sheets relating to each component. Such then get placed within the mechanical layout before getting sent to the client or customer for consent.

Drill Hole Insertion

It is a step that gets dictated by the connection and type of components. For instance, almost half of the available flex circuits prove double-sided. It implies that a connection exists at the bottom layer (where it connects the hole)

Routing of Traces

It follows the drill hole insertion phase and placement of drill holes and components. Routing of traces implies the connection of sections of the conducting path.

Incorporating Identifiers ad Labels

The process steps entail the incorporation of any identifiers, labels, reference designators, or markings to the circuit layout. Reference designators become helpful in illustrating the specific components or parts and locating them on the circuit board.

Generation of the Layout or Design Files  

It is the ultimate step in the design or layout process—files containing all the relevant details of the PCB get generated. The generation of these files also signifies that your printed circuit board is ready for production (manufacturing and assembly).

Schematic Capture

The PCB design software needs to have the provision of starting the design process from the schematic stage. It equally proves useful for complex and straightforward PCB designs, especially when you want an error-free board layout.

Automatic DRC

The PCB design software needs amenability regarding aspects like getting it to check for direct rule compliance for both complex and simple printed circuit board designs.

Backward and Forward Annotation

The circuit board design suite should allow for a backward and forward annotation as the board’s direct laying proves more arduous than starting with a PCB schematic. It also forms a fundamental requirement for all types of PCB designs.

Assisted Routing

The design software needs to possess assisted routing as an essential requirement, especially for simple boards. However, it is not a requirement for complex boards as it can get accomplished manually without any assistance.

Auto-routing

The provision of automatic routing becomes essential for complex board designs. It is therefore vital to consider this aspect before selecting a suitable PCB design suite. But remember, simple boards can get routed manually.

Auto-placement

Depending on the PCB you intend to design, getting a PCB design software that allows for the automatic placement of components can prove helpful. It mainly applies to complex boards needing lots of electronic components. However, whenever the number of components proves few, it may not necessarily apply.

Real-time Component or Parts data

For PCB designs with large components, getting a design software that can track and avail the required data proves helpful. For a more straightforward board design that needs a few components, it is possible to manually research and gets the required component’s data without much fuss.

Export Options

A top PCB design software has to have the provision of at least exporting Gerber files. However, the broader the range of formats the software program provides, the better your design needs. Such an ability is a vital aspect to consider before picking a PCB design suite.

DFM Importation

It also depends on the type of printed circuit board you want to design. However, complex PCBs require more stringent specifications that align with industry needs. Additionally, such specifications have to align with the contract manufacturer’s equipment capabilities. Simpler PCB designs can get away with general industry standards regarding DFM (design for manufacturing)

Signal Analysis

A top PCB design software needs to analyze signals, primarily if your design features multiple types of signals at different frequencies. However, for simple circuits that have singular signal types and maybe a PDN, such a capability does not apply.

Thermal Analysis

The thermal analysis becomes a crucial aspect for complex circuits requiring thermal distribution and dissipation. Such printed circuit boards involve high power with diverse signal types. However, for simple circuits, the materials used often come standard, and thus, such a capability becomes optional.

3D visualization

The ability of the PCB design suite to visualize in three-dimension becomes crucial for complex PCB designs. It especially applies when you have integrated MCAD. However, the capability proves unnecessary for simple PCB designs, especially double and single-layered PCBs.

ECAD to MCAD Integration

The printed circuit board software design has to integrate ECAD to MCAD, especially for complex boards. It allows for exact board dimensioning when it comes to installation. Simple boards, however, do not require this as they do not encompass enclosure integration.

Panelization Design

It is essential to have this capability in the design software of choice. It allows for the specification of the depanelization approach used in complex boards. The importance of having this feature dissipates when dealing with simple boards.

Comprehension of the design process is instrumental before picking a suitable and top-tier design software to use.  So what happens next? You have to pick a top printed circuit board design software. The following section will cover some of the famous and top PCB design software to consider.
