Do you know some of the details of taking care of high-speed connector design? Connector should not be a stranger to you engineers. This is one of the very common components, is the bridge between the devices connected. For high-speed connector how to optimize the design of it, in fact, there are rules to follow, the following we are to give you the popularity of the six details, hurry to learn.

1. The key to signal optimization for high-speed connections is to ensure minimal signal loss. Once the bandwidth of the connection is identified, the s-parameters can be further explored to fully understand the nature of the connection. Gathering a comprehensive understanding of these aspects allows the user to understand the potential of high-speed connections. These s-parameters are the metrics used by manufacturers to categorize connector speeds and should be given high priority. Careful attention should also be paid to the s-parameters in the time domain, which is a measure of the signal's time-dependent performance. 2, PCB termination options Designers must also consider the importance of PCB termination options. These options include: surface mount, press fit and in-hole soldering (PIH). These options have their own advantages and disadvantages. What makes press-fit terminals a reliable option is their durability. These rugged connections are very secure to the PCB, but it poses a challenge to the high speed connections that users typically require, allowing high density connectors to make it difficult to route signals out of the PCB. because the termination style typically requires more layers in the PCB, this can lengthen the signal's path, create higher frequency discontinuities, and potentially inhibit the signal's speed. 3. Surface Mount Terminals Surface mount terminals are more sensitive in their design to The design of surface mount terminals is more sensitive to impedance matching, designers can choose to establish a connection directly with the PCB. They are called "buried through-hole" internal connection in the circuit board, more effective way to improve the frequency response than press-fit terminals. This method is more effective for high frequencies that experience losses in the press-fit option, but they are hardly durable and often require additional mounting hardware to build the secure connectors offered by press-fit alternatives.4. Paste-In Hole Terminals Paste-In Hole Terminals incorporate the features of the previous two styles. the PIH style uses plated pinholes to solder the contacts to the PCB similar to press-fit. The obvious difference between these two styles is the length of the pins and the holes they use in the PIH style. The pins are much shorter, allowing holes to be drilled to minimize excess stubs on the signal. While the signal stubs are related to the length of the signal on the transmission line, the density of these styles unfortunately impedes communication with the PCB.5. Contacts The contacts within the mating connector must be considered when deciding which style to use in a system. Designers can make a variety of choices when determining contact configurations, and termination alternatives are very similar, each of these options has its own advantages and disadvantages. One such configuration is the edge-mounted connector with a narrow bar equipped with springs to guide the connection to the PCB, allowing for greater continuity. However, shock and vibration pose a threat to the integrity of the connection under stress, and security may require additional reinforcement.
