the key points for choosing a PCB connector

Increasing data rates are disrupting the PCB connector landscape, and it is important to transmit signals on the PCB, while data rates for servers, switches, routers, and storage devices have increased. So how do we enhance the I/O connection on the board? The key points of the PCB connector are shared below.

First, the appearance size of the PCB connector

First, the small connector footprint simplifies PCB design, reduces cost, and reduces transmission losses while enabling connections from point A to point B. The small contact spacing makes the connector slimmer, making it easier to have smaller boards and backplanes.

For example, connector sockets can be mounted in parallel at smaller pitches, and subsequently, a small socket footprint helps to reduce connector size, especially when multiple connectors are placed side by side on a single PCB.

Second, the PCB connector’s signal loss rate

As the exponential rise in data rate, insertion loss becomes critical, so how do you reduce insertion loss? The internal structure and the contacts inside the connector play an important role in improving signal integrity and minimizing insertion loss. In addition, the connector enhances the signal interface by improving airflow and channel impedance.

Third, PCB connector EMI and ESD shielding

At higher data rates, shielding electromagnetic interference (EMI) and electrostatic discharge (ESD) are becoming increasingly important, and physical envelopes and special mounting and termination mechanisms play an important role in ensuring protection against EMI and ESD effects.

Fourth, the cable end of the PCB connector

This is the transition point between the cable and the connector termination, which helps to reduce signal loss. For example, some PCB connectors have preloaded springs to prevent accidental cable removal, and the connector integrates the wire termination unit and cable clamp into a plug housing.

Fifth, the mechanical strength of the PCB connector

The flexible, rugged and durable connector design means it can withstand cable pull, heat, shock, vibration and other external forces. The mechanical strength of the PCB connector also ensures proper fit and connection safety.
