How to Design a PCB Layout?

In the high-speed manufacturing world, specifically in the PCB industry, it is crucial that products be designed to be produced most efficiently. This is where Design for Manufacturability (DFM) Checks come in. At PCBX, we pay attention to detail when it comes to the production process and the necessity of DFM to streamline processes and reduce costs. In this guide, we go in-depth on what a DFM Check is and why it is so crucial in the world of PCBs.<h3>Introduction to DFM Checks</h3>DFM, or Design for Manufacturability, is an engineering process segment that guarantees products are designed to be produced efficiently at low cost and high quality. A DFM Check refers to a methodical examination of a product design to identify and solve potential manufacturing issues before it is manufactured, minimizing interruptions and expenses.<img src="https://img.pcbx.com/dev/file/image/article/20250520/5a8cc266e4c64ae09399eca821e6f8a4.jpg" alt="Introduction to DFM Checks-PCBX" data-href="" style="width: 100%;"/><h3>The Significance of DFM Analysis</h3>DFM analysis is not just beneficial but also vital, reaping several benefits:Cost Savings: It is much less expensive to correct and resolve design issues at the early design phase than after production. Correction early on can prevent expensive changes.Defect Prevention: Production reproduces design defects in all the units, leading to continued defects. DFM Checks are a preventive measure to detect such flaws early.Avoiding Delays: A design that is not correct may result in reworks, which can postpone production. DFM analysis facilitates fixing those issues in advance, avoiding time loss.Enhancing Quality: A solid DFM process translates to higher assembly success rates, fewer scrapped parts, and reliable product quality.Enhanced Manufacturability: Designing with consideration for the manufacturing capabilities results in easier production processes.These benefits are the reason why leading engineering teams prioritize DFM Checks before moving designs to the production floor. The ROI in preventing manufacturing problems is high.<h3>Timing of DFM Checks</h3>In order to maximize the benefit of DFM, it must be applied during the design and development cycle:Conceptual Design Phase: Applying DFM Checks at the beginning ensures the design direction is inherently moving in the direction of manufacturing best practices.Detailed Design Phase: Complete DFM checks are carried out after finalizing the design to verify production readiness.Design Revisions: Design revisions later require a new DFM analysis to ensure new issues aren't introduced.Including DFM as a continuous process throughout development, and not as a final step, enables the detection and correction of issues early, preventing costly changes in later stages.<h3>Major Areas Analyzed in a DFM Check</h3>A DFM Analysis of PCBs examines several critical aspects:Tolerances and Clearances: Ensuring component tolerances are within established limits and electrical and physical clearances are adequate.Draft Angles and Surface Finishes: Ensuring draft angles and surface finishes are appropriate for manufacturability.Hole Sizes and Alignments: Ensuring hole diameters are to standard and include plating allowances.Fastening Considerations: Establishing the acceptability of fastening and joining mechanisms for PCB assembly.These parameters are key to pre-empting and solving manufacturing issues ahead of time, and thereby ensuring quality.&lt;button class="center btn-lg" data-href="/order/manufacturing/pcba"&gt;Get an Instant Quote for PCB Manufacturing & PCB Assembly&lt;/button&gt;<h3>DFM Principles and Guidelines</h3>There are certain underlying principles that form the basis of the DFM process:Simplicity and Intuition: Designs should be as simple and intuitive as can be, with the least amount of complexity.Error Proofing: Incorporate features that minimize the risk of assembly errors, such as guides and asymmetry.Standardization: Use standard components and processes wherever possible to make manufacturing easier.Process Abilities: Maintain designs within existing manufacturing capabilities to promote efficiency.Modularity and Streamlining: Design with modularity and streamline parts wherever possible to minimize the process.<h3>Manual vs. Automated DFM Checks</h3>DFM analysis can be conducted manually or with automated systems:Manual Checks: Relies on experienced veteran engineers to visually inspect designs, simulate assembly sequences, and utilize their experience to detect issues. Informative but may be time-consuming and subject to human error.Automated Checks: Utilize software tools to automatically detect common design issues such as poor clearances or tolerance violations. Efficient but cannot fully replace the sophisticated judgment of veteran engineers.A combination method, utilizing automated software to highlight possible issues for further manual analysis, yields the best results.<h3>Fixing DFM Violations</h3>Designers fix design flaws through modifications after identifying them with the use of DFM Checks:Changing Tolerances and Dimensions: Alter tolerances and dimensions to align with the process capabilities.Reworking Design Features: Modify surface finishes, draft angles, and hole sizes as necessary for manufacturability.Simplifying and Optimizing: Simplify complex geometries and optimize assembly sequences for operational efficiency.Many small changes can often accumulate to enhance manufacturability without the need for redesign.<img src="https://img.pcbx.com/dev/file/image/article/20250520/25a04beb47a842d1ada8bf4ef497dee9.jpg" alt="What is DFM Check-PCBX" data-href="" style="width: 100%;"/>A well-implemented DFM Check is essential for optimizing PCB manufacturing.

IoT devices anywhere in consumer and industrial use would need PCBs that could avails flexibility in functionality with efficiency in diverse environments. This involves focusing on low-power design, robust wireless, and long-term reliability.These technologies also require that PCBs support increasingly complex functionalities in an affordable manner; thus, there is a growing need for innovation in both design and materials.<h3>Thermal Management Solutions</h3>Correspondingly, improved power and compactness in contemporary electronic devices make effective thermal management indispensable in PCB design. Growing demands for effective heat dissipation solutions-like new-generation heat sinks, thermal vias, and conductive materials-must be developed in order to maintain the performance and prolong the lives of devices by keeping components within their favorable temperature ranges.In applications ranging from data centers and automotive electronics to consumer devices, effective heat management strategies are essential, as performance and reliability are seriously degraded in the presence of heat-dissipation problems.<h3>Improved Simulation and Modeling Tools</h3>The simulation and modeling tools are continuously improving to offer the designer the ability to accurately predict and optimize performance in PCB design. This is all about detailed analysis, including electromagnetic, thermal, and mechanical simulations. This is especially critical in high-speed digital and RF designs, where a minor inaccuracy can cause a considerable performance problem.These tools will also contribute to shrinking the consumed time and cost, which is a result of physical prototyping and iteration due to the allowed virtual testing and validation. This increases efficiency and ensures that the resultant product meets all set criteria for performance.<img src="https://img.pcbx.com/dev/file/image/article/20241023/3deaa97ea120432d955a6ee0165b92f9.jpg" alt="Innovations and Directions in PCB Design-PCBX" data-href="" style="width: 100%;"/><h3>Sustainability and Eco-Friendly Design</h3>In today's environ-conscious world, sustainability in PCB design is a big deal. A number of waste and energy consumption minimization in all aspects, from using eco-friendly materials to recycling, the production process draws immense concentration from PCB designers and producers.Sustainability reinforces not only the ecology but also competitiveness in that consumers and regulators are more and more focused on 'green' products and practices. This, in turn, drives companies to innovate with materials and processes that reduce environmental impact without sacrificing performance.<h3>Security-Driven Designs</h3>Security features are one of the most discussed aspects when it comes to PCB design, especially when it relates to sensitive data handling or when the devices are engaged in critical infrastructure due to the ever-increasing cyber threats. Thus, designs driven by security consider several techniques aimed at protecting data and ensuring the integrity of the device through embedding cryptographic modules, designing for tamper resistance, and enabling secure data pathways.Hardware-based security features have increasingly become a standard consideration in PCB design, especially within telecommunications, defense, and financial technologies where data security is not to be trifled with.&lt;button class="center btn-lg" data-href="/order/manufacturing/pcb"&gt;Get Your Quote Now for Rapid Prototype PCB Design&lt;/button&gt;<h3>Conclusion</h3>Finally, the trends that have taken over the PCB design landscape in 2024 reflect a fusion of technological innovation with market needs.

Through-Hole (THT) Assembly PCB Design Rules

Through-hole assembly is still one of the predominant techniques in the manufacturing of PCBs, and the reason is that it offers high reliability and mechanical strength. Thus, whether one designs for consumer electronics or the high-reliability system domain, through-hole assembly design rules ensure performance and manufacturability. This article is all about design elements, requirements, and standards for through-hole assembly.<h2>Thermal Pads</h2>Thermal connections are the most significant part in determining a good soldering and thermal management. These connections follow a spoke-like pattern, like spokes on a bicycle wheel, from the leadless pad to the copper plane or foil. The main purpose for such spokes is to balance the thermal dissipation of the copper area, such that when properly soldered, the copper does not draw away too much heat, but the thermal pad has not been squashed at the expense of current-carrying capacity. The diameters of such thermal pads are to be in keeping with internal pad diameters: the sum total of all the spokes' widths is the diameter of the pad. It is the total area that covers the pad and its spokes, and the value is 1.5 times the pad's inner diameter.<img src="https://img.pcbx.com/dev/file/image/article/20240911/fe98e2e12aa744a8ae537323061144de.JPG" alt="PCB Through-Holes Assembly-PCBX" data-href="" style="width: 100%;"/><h2>Performance Levels</h2>IPC standards classify PCBs into three classes based on various levels of complexity, functionality, and reliability requirements:<ol><li>Class 1: This class covers all products coming under general consumer electronics and a few low-reliability items. A lot of product categories that fall under this class are general types of consumer products and other types of computer peripherals.</li><li>Class 2: Better performance and more reliable nature electronics, for example – communication equipment, business machines, and military instruments. Independent occasional failure rates are okay to have in these applications.</li><li>Class 3: High-reliability electronics. Critical commercial and military systems fall into this class. System failures are unacceptable in this class of, and availability is of utmost importance.</li></ol><h3>Through-Hole Assembly</h3><h3>Component Types</h3>Axial Leads: This implies that components have leads entering and exiting on the opposite sides. They allow lead spacing, which is variable.Radial Leads: These have leads that go in and come out from the same direction. They usually consume less board size while at the same time not providing adjustability for the lead-to-lead pitch.<h3>Solder Joint Quality</h3>Strong good solder joints are the key elements in the reliable electrical interconnection between the leads and the PCB. All solder joints should be verified for proper joint strength and the absence of defects.<h3>Drill Hole Size</h3>Hole and pad sizing are important to maintain strength and the ability to form a solder joint. The target drill hole sizes are:<img src="https://img.pcbx.com/dev/file/image/article/20240911/6b1e65a1cd24438c95293a00993cde12.png" alt="PCB Min Hole Size-PCBX" data-href="" style="width: 100%;"/><ul><li>Density Level A: Min hole size = Max lead diameter + 0.25 mm</li><li>Density Level B: Min hole size = Max lead diameter + 0.20 mm</li><li>Density Level C: Min hole size = Max lead diameter + 0.15 mm</li></ul><h3>Annular Ring Size</h3>The annular ring should have a fair width for a sound solder joint. For through-hole components, the pad diameter shall be made as follows according to IPC-2221:Density Level A: Pad Diameter = Minimum Hole Size + 0.1 mm + 0.6 mmDensity Level B: Pad Diameter = Minimum Hole Size + 0.1 mm + 0.5 mmDensity Level C: Pad diameter = Minimum hole size + 0.1mm + 0.4mm<img src="https://img.pcbx.com/dev/file/image/article/20240911/612c99ad9e7f4d0cba1d320970fa8cad.png" alt="PCB Pad Diameter-PCBX" data-href="" style="width: 100%;"/><h3>Solder Mask Relief</h3>Solder mask relief usually conforms to a general tolerance of 4 mils (0.1 mm) around the pads or annular rings. This rather liberal space gives room for appropriate soldering without bridging.<h3>Solder Fill</h3>Though 100% fill of the solder is the preferred option, often a rate of fill of 75% is acceptable for both Class 2 and Class 3 boards. In this way, mechanical strength and thermal conduction is gained by reducing surplus solder.<h3>Clearance and Separate Drill Files</h3>Sufficient clearance in the holes ensures a good flow of solder and rules out dual-side soldering, which is time-consuming. Always provide a separate drill file for plated-through holes (PTH) and non-plated-through holes (NPTH) to avoid conflict during manufacturing.<h3>Component Mounting Order</h3>Mount the flatter and smaller components first, then as you go along, increase to the larger and taller components. This kind of ordering will help to sustain efficiency and can rule out obstacles in the mounting process.<h3>Other Design Considerations</h3><ul><li>Masking Tapes: Masking tapes can be applied on the short component leads to allow for easy bending.</li><li>Conformal Coating: Apply conformal coatings to prevent corrosion.</li><li>Potting: Utilize potting methods to provide mechanical and electrical stability.</li><li>RoHS Compliance: The manufacturer shall support Restriction of Hazardous Substances with regard to environmental protection.</li></ul>Thermal Considerations<ul><li>Even heat distribution is important during proper soldering. The leads and pads should have even heating so that the solder sticks to them. Take notice of the parasitic capacitance and inductance involved in conventional designs on PCB, of which high-density board design is imperative.</li></ul>Specifics for High-Density Designs<ul><li>For high-density requirement boards, choose through-hole diameters as follows: Via: 0.20 mm, pad: 0.46 mm, isolation area: 0.86 mm.</li><li>Indeed, inductance can be improved by placing through-holes close to power and ground pins, which helps in overall performance and reliability.</li><li>By adhering to these guidelines on through-hole assembly design, a PCB designer can have robust, reliable, and manufacturable PCBs that comply with the performance criteria their application requires. All of these best practices are at the heart of effective and efficient through-hole PCB design and assembly, ensuring in-production and in-field success.</li></ul>

Through-hole assembly is a key PCB manufacturing technique offering reliability and mechanical strength. This article details design elements, requirements, and standards, including thermal pads, IPC performance levels, component types, solder joint quality, hole sizes, and annular ring dimensions, ensuring robust and manufacturable PCBs for various applications.
