How To Reduce The EMI Effect In A Transmitter PCB?

A transmitter PCB suffers from different EMI (Electromagnetic Interference) effects. These effects hamper signal transmission in many ways. That’s why you have to be aware of the EMI reduction techniques of the PCB.

• Sometimes, there is an excessive flow of energy via the conductors that produce conductive EMI. A well-placement of PCB components and regulated voltage supply reduce this type of EMI.
• Bypass capacitors create capacitive EMI in the power supply line. You have to place these capacitors far from the IC to avoid the capacitive EMI effect.
• When a bad signal is transmitted, it creates radiative EMI. You can apply the cable shielding method to resist the transmission of undesired signals.
• Proper use of component shielding can reduce inductive EMI effects. This EMI occurs in the connected lines or PCB ground planes. Component shielding controls the antenna size to absorb such EMI.

Transmitter PCB EMI Reduction

Which EMI Shielding Process Is Useful To Transmitter PCB?

To resist EMI in a transmitter PCB, there are some effective ways to apply. The two most useful EMI shielding processes are explained here.

Cable Shielding Method

In data transmission technology, cables are the most common source of EMI. That’s why cable shielding absorbs the effect of EMI to a large extent. Again, this type of protection is useful to reduce parasitic capacitance, inductance, and resistance.

The cable shielding process is also reliable to resist EMI in high-frequency PCB applications.

Component Shielding Method

This is the most applied EMI shielding process in transmitter PCB. Component shielding provides great resistance against the penetration of EMI in transmitter PCB components.

Transmitter PCB EMI Shielding

This cable assembly shielding separates the EMI-producing component from the electric circuits. Then it makes a connection to the ground and minimizes the loop of the antenna. Thus component shielding reduces the EMI effect.

In most cases, shields are made of metal. “Faraday cage”, is a good example of component shields. It is designed with metal or foam to protect the PCB components from radiative EMI.

What Are The Limitations Of A Transmitter PCB?

Transmitter PCB has a lot of varieties. Each type provides immense benefits along with some limitations as well.  Here, the notable limitations of a transmitter PCB are given.

• It is EMI-sensitive. So, you need to apply protective care to resist the EMI effect.
• Its cost is comparatively high.
• The circuit design of a transmitter PCB is more complicated compared to other PCB solutions.

How Do You Test A Transmitter PCB?

A transmitter PCB requires regular inspection to maintain its high efficiency. We are here with some reliable performance testing methods of transmitter PCB.

Automated Optical Inspection

This is an image-dependent automated test of transmitter PCB. Here, the AOI machine captures some images of the PCB from different angles. A high-quality camera is integrated with this machine.

The inspector compares these images with the most perfect transmitter PCB. This is conducted automatically through the AOI machine. That’s why it is a fast but costly testing procedure. But, Its outcome is beyond question.

Electrical testing

Electrical testing checks the functionality of a transmitter PCB at a specific current supply. The inspector checks the connections, solder joints, component placement, current rating, voltage drops, etc at a certain temperature and pressure.

Transmitter PCB testing

So, it takes a huge time. But this test can provide a trustworthy result at a low cost. You can also apply flying probe tests, visual tests, etc to check the performance of a transmitter PCB.
