PCB Connector By Type

PCB Edge Connector

The PCB Edge Connector that we produce in this particular product line is considered a cost-effective approach since it doesn’t require multiple female connectors. Instead, it only necessitates a single separate female connector.

PCB Mount Connector

The PCB Mount Connector that we produce in this particular line of products empowers the linkage of the item to the hardware board, defensive compartment, and outside packaging. In addition, they are referred to as mechanical elements.

Flex Connector PCB

The Flex Connector PCB that we produce in this particular product line has been brought into the market due to rising demands for smaller centerline or pitch spacing, lower profile heights, and lighter interconnect solutions in various devices.

USB Connector PCB

The USB Connector PCB that we produce in this particular line of products is considered the highly utilized connector in the market; they are frequently employed in smartphones, mice, and keyboards to connect to a computer or laptop.

PCB Wire Connector

The PCB Wire Connector that we produce in this particular product line enables the connecting of a cable to a PCB, primarily often using the crimping technique. Additionally, it can include IDC and SMT, and they are used for flexibility and reliability.

High Current Connector PCB

The High Current Connector PCB that we produce in this particular line of the product makes it possible to achieve field-friendly, reliable, high current cable to PCB dismissals that are minimal. They are ideal for low-volume and high-volume.

What is PCB Connector?

Since we already know what a PCB is, we can dissect the definition of its connectors. In some circumstances, a single electrical device may contain several PCBs. PCBs must be able to communicate with one another. On the PCBs, there are identical conductive traces linking the components. There is also an option to interface pads on the PCBs.

To link to other gadgets or PCBs within the same system, PCBs use a variety of components. The hardware that interconnects PCBs is known as PCB Connectors.

Furthermore, PCB Connector ports enable the transfer of data, signals, or functionality to various devices or PCBs. In contrast, information might be obtained inside a single entity or sent elsewhere. By fitting connectors onto PCBs, connections are neither fixed nor complicated, making them flexible in use.

What is the Wire-to-Board Connector Types?

What is the Wire-to-Board Connector Types?

In essence, it is a form of PCB Connector that joins a cable to the board; linking circuitry has been made simple owing to this device.

Below are some types of Wire-to-Board Connector:

  • Wafer Connectors –In contrast to female connections, which are pinched to the wire, male connectors are linked to the PCB. It follows that the female interface doesn’t need to be soldered.
  • Ejector Headers – It offers an ejector feature for quick hookups and disengages.
  • FPC/FFC Connectors – These wires have a curvature that resembles a ribbon and are often constructed of flexible plastic or film with a metallic junction.
  • IDC Connectors – It is made with blades that may be honed to remove wire shielding when connecting.

What is the Board-to-Board Connector Types?

They are often essential small interface jacks and adapters that can link power supplies and signals across PCBs using their pins. Compared to the other interfaces, they have the quickest transmission rate, reaching up to 28 Gbps. These connections’ principal pitches, which are frequently used, are 0.4, 0.5, 0.635, 0.8, 1.00, 1.27, 2.0, 2.5, etc.

The fundamental tenet of how board-to-board connectors operate is that male ports and receptacles must correspond. Fine pitch board-to-board, SMT board-to-board, right angle board-to-board, and spring-loaded board-to-board are the four typically utilized Board-to-Board connectors (pogo pins). Other interfaces are used for additional specialized requirements, like memory: DDR, PCB/PCI Expansion slots, etc.

PCB Connector Fabrication

Different PCB Connector Orientations

Typically having a rectangular layout, a simple multi-pin connection mechanism is referred to as a PCB connector.

A matching pair of PCB adapters will be used for either board-to-board or cable-to-board connections. With 90-degree increments, it may offer a variety of orientations.

The first is Parallel or Mezzanine; both connections are placed in a vertical position. Next, we have 90 Degrees, Right Angle, and Motherboard to Daughterboard.

In essence, one link is horizontal; the other is vertical. Ultimately, 180 Degree, Coplanar, and Edge-to-Edge; connections are both horizontally oriented.

If you wish further information on this topic, kindly message us.

How to Mount PCB Connectors?

Data or power can be transported from one PCB to another via PCB connectors. Hence, let’s talk about the various mounting options.

There are two methods for attaching PCB connectors to a PCB. We have the following: Surface Mount Technology (SMT) and Through-Hole Mounting (THM).

First, Through-Hole Technology (THT); is capable of handling stress and high temperature compared to SMT Components; thus, they are ideal for such applications.

Second, Surface Mounting Technology (SMT); utilizes a Surface Mount Device (SMD) technique to integrate its components by a direct attachment.

How to Select the Right PCB Connector?

A PCB can have external connections provided by connectors. We must choose the appropriate link whether we are sending power, data, or high-speed networking.

When choosing a connection, designers will primarily be concerned with PCB footprint, but additional factors must be considered. We’ll discuss it in this section.

  • Price – It is advisable to consider the cost before the design process to prevent bottlenecks in its manufacturing phase.
  • Polarity Protection – We suggest taking into consideration the end user’s need. Polarized connections should be utilized if there is a chance that an erroneous hookup will harm the PCB board. These polarized connectors lower the risk of a fault current by preventing incorrect board couplings.
  • Rating and Temperature – It is necessary to check out its thermal capability to prevent melting; consider looking out for its current flow capacity and operational temperature.
  • EMI/ESD Protection – To safeguard the signals on the PCB, insulated connections are required. Thus, developers should consider these protected interfaces’ potential price premium.
