The limitations of standard PCB technology. Is HDI unavoidable?
Standard PCB design and manufacturing techniques have served us well for years, providing a reliable and cost-effective solution for a wide range of applications. But in today's electronics landscape, the shift towards miniature components and PCBs is forcing even the most seasoned designers to rethink their approach.
Will HDI become unavoidable
More frequently designers like you are finding that key components — previously available in standard packages — are now only available in tiny packages with a very fine pin pitch. This change can be frustrating, as it may require entering an unfamiliar PCB design territory, with greater clearance restrictions, complex routing, and costs.
For many of you, the transition to HDI isn't always driven by choice, but by necessity, and it brings its own challenges, such as:
- Tighter pin pitch: Components with finer pitches require precise routing with thinner tracks and gaps together with more advanced techniques such as microvias.
- Higher layer counts: As routing becomes denser, more layers are needed to manage the connections effectively.
- Signal integrity and reliability concerns: The increased complexity of HDI designs demands careful planning to maintain signal integrity and avoid manufacturing errors.
But why should you go to full HDI with all its disadvantages for one or two fine pitch components you are forced to use in your design!
Eurocircuits has developed a solution:
- Simplified HDI solution: Our PCB Visualizer will feature support for HDI layouts, helping you transition from standard to advanced designs effortlessly. We'll make sure you have the guidance you need at every step, from design verification to manufacturing readiness.
- Affordable HDI service: Our HDI solution won't 'break the bank'. We are committed to offering cost-effective HDI manufacturing pooling options, as you would expect from us, that align with your budget, ensuring you can keep your projects moving forward without skyrocketing costs.
- Expert guidance: You don't need to face the HDI challenges alone. Our team of experienced engineers will be there to help you navigate this new terrain, offering predefined fan-outs for a range of widely used component packages and personalized support to make sure your HDI designs are 'right the first time'.
- Fast and reliable prototyping: With our Right First Time manufacturing approach, we'll help you get your HDI prototypes turned around quickly and accurately, minimizing any disruptions to your workflow.
HDI, may seem hard to avoid in the future but let's tackle it together
