PCB Shielding with Gold Coatings

PCB Shielding with Gold Coatings:

Electronic shielding is an important part of circuit design. The shielding provides a barrier between the circuits and the outside world, shielding sensitive components from noise, electromagnetic interference (EMI), power supply fluctuations/spikes, and other types of interference. To protect against EMI in particular, PCBs are often shielded with either metal foil or conductive paint applied to specific areas on the board that need protection. This blog post explains how to solder gold coatings onto your PCB boards for better shielding performance.

Gold coatings:

Gold coatings offer several advantages over other shielding materials. First, gold is an excellent conductor of electricity and provides good shielding performance. Second, gold does not corrode or tarnish over time like some other metals, so it will continue to provide effective shielding for your PCBs long-term. Third, gold is a visually appealing coating that can add a touch of elegance to your PCBs.

If you are looking for a way to improve the shielding performance of your digital circuits, consider soldering gold coatings onto your PCB boards. Gold coatings will help keep your sensitive components safe from EMI and other types of interference, and they look great too!

Shielded zippers:

Shielded zippers are well known for being durable, long lasting products. The zipper itself costs very little compared to the product as a whole, and is usually the first thing to wear out on an item.

A typical metal zipper has two metal plates which come together to form the teeth of the zipper. When these plates are closed, they create a short circuit and complete the circuit between the two sides of the zipper.

 

Gold shielding is a great choice for shielding your PCB and digital circuits.

There are many different choices of gold shielding on the market, but we recommend using Electroless Nickel Deposited (ENDP/EPC) Gold as it has some unique properties that set it apart from other types of coatings such as: better solderability, better corrosion resistance, and a very thin gold layer.

When it comes to shielding your PCB, the most important property of any shielding material is its ability to attenuate (reduce) electromagnetic interference (EMI). Gold has one of the highest attenuation coefficients of all metals, meaning that it is very effective at shielding against EMI (and ESD, for that matter).

Another great advantage of gold shielding is its solderability. ENDP/EPC Gold has the highest wetting ability out of all types of nickel shielding. That means soldering will be a lot easier with this type as it wets to both lead and lead-free solder very well without having to use a lot of solder paste. This shielding also has great corrosion resistance, which means that it will last longer than many other types of shielding materials that are out there, such as nickel plating or copper shielding.

Finally, Gold is one of the thinnest coatings available in metallic shielding with a thickness range from 0.02 to 0.05 μm (20 to 50 nm). This means that it is much easier and cheaper to apply the shielding material as opposed to other types of shielding such as nickel plating or copper shielding, which require a much higher thickness in order for them to be effective at shielding your PCBs.
