The Connector PCB Miracle

The Connector PCB Miracle

Connectors keep our electrical connectivity flowing from one piece of equipment to another. From simple pin headers to socket designs, there are thousands of off-the-shelf options available in most catalogs. But if you can’t find what you need, most connector vendors will custom design something just for you. This usually has an NRE charge and a longer lead time.

Multilayer PCBs

PCBs are the heart of electronic devices, providing a reliable connection between various components. They can be found in modern-day consumer electronics, such as smartphones, mobile tablets and laptops. They are used for their multifunctionality and small size. However, it’s the multilayer PCB that has become increasingly popular due to its increased functionality and improved durability.

Multilayer PCBs can be made with a variety of different materials. They are fabricated by using a process that uses heat and pressure to bind the conductive layers together. These layers are then encapsulated with resin for a safe and guaranteed final result. The layered Connector PCB Miracle structure of these PCBs helps them to withstand high temperatures and physical stress, making them more durable than single-layer boards.

These PCBs also provide a higher assembly density than single-layer boards, making them ideal for compact gadgets. This means that more functionality can be packed into a smaller space, which ultimately reduces the overall weight of the device.

However, a multilayer PCB can be costly if it is not designed correctly. To avoid this, it is essential to use advanced CAD tools that offer features like impedance control and layer stack-up management. It is also necessary to carefully strategize the layers in accordance with the design prerequisites, including signal integrity and power integrity. A well-planned layer stack can also significantly improve EMI performance, reducing external noise by a factor of 10. This is especially important for high-speed applications.


When reliability is paramount, engineers turn to high-rel connectors. These components offer superior performance in the face of a variety of demanding conditions and are ideal for life-saving medical equipment, motorsport applications, and high-end industrial use.

The best high-reliability connectors are designed with a metal backshell to provide 360deg electrical screening and shielding from EMI and RFI interference. They’re also capable of withstanding a wide range of temperatures, shocks and vibrations.

To qualify as a high-reliability connector, it must be tested and rated according to specific standards. These include MTTF and MTBF, which measure the time it takes for the connector to reach failure under a set of operating conditions. While these metrics are useful, they don’t fully describe the performance of a specific connector.

When it comes to selecting the right high-reliability connector, consider its size and the number of contacts needed for your application. In addition, make sure the connector is compatible with other components in your system. This will help ensure that the connection works as intended and minimizes performance loss over time. It’s also important to inspect the connector regularly for signs of physical damage or wear, as these can compromise its ability to perform as expected.

Audio Attenuators

There are many different types of PCB connectors on the market depending on the final application and the size, weight and power requirements. For example, a connector used in a cell phone needs to be smaller, lighter and have the ability to withstand high currents. While a connector used in an automotive engine will need to be larger, heavier and have the ability to handle high voltages.

In audio applications, a common problem is that a CD player or other source can put out so much signal level that the volume control on the amplifier hardly moves over a tiny portion of its range. This can lead to poor control at low levels and also to distortion at high levels.

One solution is to use an attenuator between the amplifier Connector PCB Miracle Supplier and the speakers. These devices look the same to the amplifier as an ohm load and can reduce the output level by converting excess wattage into heat. This can also protect the speakers by preventing them from getting overdriven.

Rothwell’s in-line attenuators are easy to fit and work with amplifiers of all types, from budget equipment to the very highest end. They can be purchased from many retailers and dealers and online at the Rothwell website. Payments are securely processed by Worldpay. UK VAT (value added tax) is deducted automatically.


A custom PCB can help your design reach a new level of performance or functionality. For instance, a customized connector can be designed to allow power and ground to share space on the same pins. This helps reduce the overall number of required connectors. Additionally, it can be engineered to meet a particular operating target, such as ruggedness or temperature.

One of the most important aspects of a good PCB is its form factor, which includes things like insulators, pinouts, and overall size. In general, the insulator used should be able to resist the electrical current and voltage that will flow through the connector. Likewise, the pinout should be the right size and have the correct polarity. Lastly, the connector should be able to accommodate any required mechanical features such as locking mechanisms and shrouds.

Another area that needs to be considered is how the connectors will be mated together on the board. For this, there are several different methods of depanelization that may be utilized by your contract manufacturer (CM). Scoring, which uses V-shaped cuts between adjacent boards, is often less flexible than routing, which utilizes perforations or solid tabs and allows for edge connectors. In addition, you should consult with your CM to make sure that the panelization scheme you choose will be compatible with their equipment.
