What is an HDI Printed Circuit Board?

HDI Printed Circuit Board (High Density Interconnect) technology enhances the functionality of conventional PCBs by optimizing space that’s available, by increasing the number of circuits that can be included. Through creating smaller components and placing vias more efficiently, HDI technology frees up real estate on the PCB. So, users can experience improved functionality and data storage.

We are extremely thankful to JLCPCB for sponsoring projects on this website and youtube channel. JLCPCB s the foremost PCB prototype & manufacturing company in china. Providing us with the best service we have ever experienced regarding (Quality, Price Service & Time). We strongly recommend ordering PCBs from JLCPCB. All you need to do is just download the Gerber file and upload it to the JLCPCB website after creating an account as mention in the video above. Visit their website today to look for more!.

Step 1: Benefits of Using HDI Printed Circuit Boards

1) Minimizes Crossing Delays & Signal Loss

In HDI PCBs, circuit board components are in close position to each other, this causes the signals to travel faster between units, which ultimately reduces crossing delays and minimizes signal loss.

2) Higher Processing Power Within a Small Surface Area

At this point, we all know that HDI PCBs are more interconnected and require a smaller surface area. But the fact is that they’re even more compact than simple PCBs. Yet, they provide the same (and sometimes higher) processing power as a standard PCB.

3) Maintains Signal Integrity & Diminishes Signal Scatter

HDI PCBs also integrate via in pad and blind via technology. This configuration keeps components closer and preserves the integrity of the signal and reduces signal scatter. This promotes the operational health of the PCB. Allowing it to function correctly for a long time.

4) Less Prone To Errors & More Durable

Since HDI PCBs utilize stacked vias, they have effective resistance against variable environmental conditions. This means that the finished product is less prone to errors and is way more durable than a normal PCB.
