What Is Glass PCB and How To Build It

PCB industry has seen revolutionary development in the last decade due to immense demands by electric and communication device manufacturers in LED,LCD,and 5G devices. Hence,PCB manufacturers such as FX PCB have been compelled to develop various PCBs,and Glass PCB is one of its newest additions. Glass PCB refers to a printed circuit board developed and designed on transparent glass to add durability and heat resistance for complex performance. But what is glass PCB in reality? Also,what are the advantage and applications of transparent glass PCB? We understand that these questions will evoke in your mind if you are in the PCB manufacturing industry. So,our experts have developed this content to clear your confusion regarding glass printed circuit boards.

What is Glass PCB?

Glass PCB is used widely in building modern-day 5G smartphones,LED and LCD devices. But what does it mean in reality? The glass PCB is built using a glass substrate instead of the conventional FR4 or metal ones,and so,it gets the name.  Since glass is already known for its heat-resistance feature,it doesn't need any special heat treatment in PCBs. It is a great relief for PCB manufacturers since most will need to invest hugely in making their PCB substrate heat-resistant in demanding conditions. Plus,PCBs made using glass can illuminate at a 360° angle. Hence,LED and LCDs made using the glass printed circuit board will offer maximum illumination. Its 360° light-emitting facility comes in handy for different applications. The glass PCB is one of the latest additions in the PCB industry and so,you must choose the right manufacturer for this high-end PCB.

Benefits and Application of Glass PCB

Glass PCB is designed to offer you maximum customization in device manufacturing. It comes with some unique benefits that you can’t simply ignore. Most PCB experts recommend that using glass-made printed circuit board increases the durability of LED and LCD devices. Its basic advantages include the following-

1. The main advantage of using glass as a PCB substrate is its flatness and smoothness. The manufacturer doesn’t need to invest additional to flatten and smoothen the substrate.
2. Glass is extremely sturdy,and so,it has the least deformation among the PCB elements. Since it won't deform in demanding situations,you can easily use it in complex jobs where durability is of the utmost necessity.
3. Glass is also known for working successfully in high-temperature for a long period. So,it enjoys improved durability in extreme temperatures. This comes in handy in smartphones and LED panels as these will be used for long hours without any rest.
4. Glass PCB,unlike other PCBs,offers 36-degree luminescence. So,using it will help to illuminate LED and LCD panels the entire surrounding. It is a great benefit since no other PCB can illuminate an entire circuit board surface.
5. You don’t need to add a heat sink with the glass PCB. It is already highly resistant to heat and doesn't need any additional treatment,a money-saving deal.
6. Glass printed circuit board has no light attenuation either. So,the intensity of the light passed through the panel doesn’t reduce. It is beneficial for LED lighting where the aim is to provide maximum lighting through the minimum energy.
7. The color rendering index of glass PCB is at 80. Also,it can go beyond 140lmw or even more in case of demanding situations.

As you see,glass PCB comes with unique advantages. Hence,it has wide applications in different industries. You may see its use in 5G smartphones,3D printers,solar panels,and LED panels most commonly. It is used in medical,military,and high-frequency signaling sectors too. As the glass made printed circuit boards are highly heat-resistant and has the 360-degree illuminating ability,its use in the different sector is increasing day by day. Plus,the glass PCB is made for use in the most complex devices,which adds to its benefit.

Where to Find the Best Glass PCB Manufacturer?

We have already stated that glass-made printed circuit boards are the newest addition in the PCB industry. Hence,not many manufacturers excel in producing PCBs with the glass substrate.
