1. Understanding the PCB Designer’s Role and Career Trajectory

Printed circuit boards (PCBs) have revolutionized electronics since their emergence in the 1950s. Initially, PCB design was a hands-on craft, with designers meticulously creating layouts on drafting boards using tape, knives, and stickers. These designs were then transferred to film using reduction cameras for PCB fabrication.

Today, PCB design relies on advanced computer-aided design (CAD) systems. A PCB designer is responsible for creating everything from component models (schematic symbols and PCB footprints) to the copper connections on the finished board. This process involves placing components and routing electrical connections using traces. Designers also define crucial structural elements, including:

Layer arrangements
Materials
Solder mask specifications
Silkscreen markings
Via designs

PCB gerber file

The output from your PCB CAD software will eventually be turned into a set of Gerber files

As a PCB designer, you’ll need a solid grasp of CAD tools, electronic components, and the PCB manufacturing process, covering both bare board fabrication and PCB assembly. With experience, designers often take on more engineering responsibilities, such as circuit design and component selection, becoming vital contributors to product development.

Some PCB designers also specialize in embedded development, integrating programming skills with PCB design. Many modern products rely on embedded applications or operating systems, requiring PCB designers to collaborate closely with programmers to align physical design requirements with programming needs.

2. Essential Education for PCB Design

Education is the cornerstone of any career, particularly in a technical field like PCB design. While formal PCB design programs are not always prevalent in universities, various learning opportunities exist. These range from engineering degrees with PCB design components to specialized industry courses aimed at enhancing practical skills.

Traditionally, PCB design could be learned on the job due to its emphasis on drafting and scale modeling. However, the increasing complexity and skill requirements now favor candidates with a strong educational background. An electrical engineering or computer engineering degree is highly recommended, providing a broad skill set essential for modern PCB design roles. For those interested in manufacturing or process development, a degree in materials science or chemistry can be particularly beneficial.

Key courses to consider in an engineering degree program include:

Circuit design and simulation
PCB layout classes
Basic electromagnetics
RF design and antennas
Power systems

Many companies are now requiring degrees for PCB design positions

3. Industry-Specific PCB Design Courses

While there isn’t a dedicated degree for PCB design, industry-level courses can bridge the gap between academic engineering programs and the practical demands of professional design. Notable options include the IPC Certified Interconnect Designer (CID) course and the PCE-EDU course from the Printed Circuit Engineering Association.

These courses offer specialized knowledge and skills essential for PCB design professionals. They cover industry standards, best practices, and advanced techniques, enhancing your expertise and employability in the field.

The future is bright for PCB design

4. Mastering CAD Tools for PCB Design

Proficiency in CAD tools is essential for PCB designers. While open-source PCB design software can be useful for beginners to learn the workflow, professional environments typically require more robust CAD tools.

Consider exploring educational licenses for paid CAD tools, such as Altium Education, which provides free licenses and training resources. This will prepare you for advanced industry-level courses like CID or PCE-EDU, enhancing your skills and career prospects.

5. The Promising Future for PCB Designers

The demand for skilled PCB designers is on the rise, driven by the increasing prevalence of electronics in everyday life, including the Internet of Things (IoT). As experienced designers approach retirement age, new onshoring initiatives and job openings are making PCB design an appealing career choice.

If you have a passion for creating and problem-solving, PCB design might be the perfect fit.
