PCB Connector: The Complete FAQ Guide

PCB connectors are an essential component of PCBs. In the present day, the PCB is at the core of all electronics. PCBs are circuit boards that link electrical components to power electronics and functions. PCB connections are also utilized to ensure a variety of functions of PCBs.

PCB connectors are required for connecting the PCB to other devices. You may have several queries concerning PCB connectors. In this article, we shall attempt to educate you on PCB connection facts. Let’s take a step ahead together.

What Is PCB Connector?

The PCBs were stated before. We are assuming you already know what a PCB is. PCBs are required to communicate with other PCBs, and in some cases, a single electronic device may include many PCBs. The conductive traces connecting the electrical components on the PCBs are the same. Pads on the PCBs can also be linked to one another.

PCB Connectors

PCBs employ a variety of hardware to link to other devices or other PCBs in the same device. PCB connectors are the hardware or connectors that are used to connect PCBs.

PCB Connector plugs permit information, sign, or the ability to be moved to different gadgets or PCBs. On the other hand, information can be shipped off or gotten from various sources inside a similar unit. Since there are no set associations or complex associations by patching connectors into PCBs, they are adaptable to use.

Let’s dig into the deep of PCB connectors with the following video:

What Are The Wire-To-Board Connector Types?

Various types of PCB connections are used by many PCBs, depending on their requirements. All connections, however, fall into one of two categories. Board-to-board and wire-to-board connections are the two types of connectors.

Connectors that link PCB connectors to PCB headers are made of wire, or cables are wire-to-board connectors. The wire-to-board connections provide the simplest, most cost-effective, and most reliable connecting options for PCBs used in illumination, automobile, telecom, and industrial applications.

Wire-To-Board Connector

The wire-to-board connector is a type of PCB wire connector that is used chiefly for non-complex circuits.

A wire-to-board connector has several key factors as follows.

• Bellmouth: The flare produced on the edge of the transmitter pleat fills in as a pipe for the cable beaches.
• Conductor crimp:  The mechanical force of the extremity around the wire’s conveyor is the essential part of the connector.
• Conductor brush: The wire coasts that reach out past the crease on the contact side of the PCB terminal connectors are known as conductor brushes.
• Insulation crimp: Protection pleats give wire backing and strain alleviation during inclusion into the lodging.

The Wire-to-board connector improvement is growing the associating frameworks step by step. Wire-to-board associations are equipped for giving long-haul, reliable, and versatile administrations. In any event, for associations with the littlest pin pitches and PCB pin connectors, this can move flows of up to 2 A.

What Are The PCB Connector Types?

Based on usability, there are numerous PCB connector types here.  Some common types of PCB connectors include-

USB PCB Connector

What Is PCB Connector Orientation?

PCB connector orientation refers to the multi-pin connection mechanism used in a rectangular format. Wire-to-board and board-to-board associations would both benefit from a decent PCB  orientation or arrangement.

• Parallel or mezzanine: In the parallel PCB connector orientation, both connectors are placed by vertical orientation.

Parallel Orientation Of PCB Connector

• 90 Degree, Right Angle, Motherboard to Daughterboard: In this case, one of the connectors is vertical, and another one is horizontal;
• 180 Degree, Coplanar, Edge-to-Edge: in 180-degree PCB connector orientation, both connectors are implemented by horizontal orientation.

How Many Pins Does The PCB Connector Have?

Essentially, the PCB connections use rows of pins. The pin headers of pin connections manage the orientations of the pins. The distances between PCB connection pins range from 0.1 to 0.0197 to 0.2 inches.

A 4 Pin PCB Connector

If we want to talk about the number of pins in connectors, it would not be wise to talk because the number of pins for different PCB connectors varies. There is no such fixed number for PCB connector pins.

But we could say that PCB connectors could have pins that start from 2, and it could be as much as needed for the specific models.

What Are The Applications Of PCB Connectors?

The main application of the PCB connectors is to connect the PCBs with PCBs or connect the PCB components. PCBs are used in almost every electronics nowadays. So, the uses of PCBs are vast, so the PCB connectors.

How Do You Use a PCB Connector?

The PCB connectors are used to connect power and signals to the PCB. Using the tried-and-true push-in technique, swiftly and simply connect the conductor. A vibration-proof electrical connection is provided by the inbuilt contact spring.

You Can Install Connector Simply By Pushing

The space-saving integrated design of the handy central flange ensures a stable connection. Touch-proof power connections give an extra layer of security during assembly.

How Does PCB Connector Operate?

The PCB connectors can deal with flows of up to 20 amps and voltages of up to 400 volts. Furthermore, this may occur at a tolerable application temperature of 55°C with next to no extra scaling down. Material discernible locking hooking guarantees that the associations are secure. This likewise ensures a solid lodging and contacts that can withstand pressure and vibration.

The hooking strategy considers finger-safe lodging, which forestalls contact with any conductive parts. As a rule, the middle locking switch gives both material and aural mating feedback.

What Is The Board To Board Connector?

Board-to-board connections are used to link two PCBs together without a cable or other connector. When “hard soldering” is used, this connection might become permanent. As a “fit and forget” option, you can apply this strategy when no pairing cycles are needed.

However, connecting and detaching PCBs are necessary to ease assembly and provide design flexibility in most situations. A “mating cycle” refers to the process of mating and unmating pin headers and socket connections.

BTB connections are classified into four kinds of mounting configurations:

• Through-hole Technology
• Surface Mount Technology (SMT)
• Plug-in technology
• Stacking mezzanine technique that does not need soldering

The mounting approach, pin pitch, amount of rows, pin size, stacker height, and other factors are considered while selecting BTB connections.

Board to Board Connector

How Do You Mount  PCB Connectors?

PCB connections are used to transport signals or energy from one PCB to the other. The PCBs are not hardwired with connectors and can be integrated later in the manufacturing process, enabling Design for Manufacturing simple.

You must mount PCB connectors to the PCB to use them. There are a variety of ways to attach PCB connectors to the board. According to the following, they are:

There are two techniques for installing PCB connectors on a PCB. Surface Mount Technology (SMT) and Through-Hole Mounting (THM) are two different types of mounting.

Through-Hole Technology (THT)

Through-Hole Technology (THT) is the method of attaching leads to PCB connections using plated through holes. THT components may also be easily replaced in the event of a prototype, making them ideal for testing.

THT components can withstand stress and high temperatures better than SMT components. This makes THT the best option for parts exposed to these conditions.

PCB Through Hole Technology

Surface Mounting Technology (SMT)

This technique uses Surface Mount Packages for its components (SMD). These parts have leads under or around the housing.

This video explains SMT and THT and shows how to mount PCB components.

How Do You Design A PCB Connector?

You can design your PCB Connector using Altium, Eagle, or SolidWorks, PCB Connector. Designing it from scratch will take some time. A professional PCB manufacturer, such as PCBMay, can assist you in creating custom PCB connections for your business.

Your PCB design tools go well beyond the standard design rule checks when it comes to board-to-board connection placement. One of the first things you should do is make use of the available library tools and plugins.

The ability to examine 3D models in your design tools is another unique feature. By incorporating 3D tools into your PCB layout, you will get valuable insight into how the components will appear on the board as a whole.

Having access to mechanical and other system layout data will aid in the creation of connections for PCB board-to-board interfacing. So you may avoid repeated board spins throughout product development and save time and money.

What Is A Solderless PCB Connector?

Solderless PCB connectors can be quickly and simply installed utilizing screws and prepositioned dowel pins. Screws for PCBs with a maximum thickness of 1.5 mm are incorporated.

These use longer screws to extend the dimensions. Measurement and testing at ultra-high frequencies need low radiation and coupling to other circuits.

Solderless PCB Connector

When Do You Use Solderless PCB Connectors?

Many manufacturers are unfamiliar with solderless PCB connections. Solderless PCB connections provide several benefits. However, owing to certain constraints, you cannot use solderless PCB everywhere.

You can use solderless PCB connectors in these regions.

• You can purchase the equipment and components at a low cost.
• Make disassembly of PCBs more convenient.
• Disconnecting is easy when you need to make changes or repairs.
• Where the link is completely sealed off from the outside world so that no moisture may get in, otherwise, the connection will deteriorate.

What Is PCB Connector With Ribbon Cable?

PCB ribbon cable connectors are wires that run parallel with each other on a flat surface. This results in an overly broad and flat cable.

Internal computer peripherals, including hard drives, CD drives, as well as floppy drives, use ribbon cables. In specific earlier computers, these ports were also used to connect external devices. In addition to making cables more challenging to manage, ribbon cables have mostly been phased out for external connectivity. They are now being utilized inside because of their round shape, which improves computer cooling by reducing airflow.

How Do You Select A PCB Connector?

Connectors are used to offer external connections to a PCB. Whether it is power, data, or high-speed communications, we need to pick the proper connection.

Designers will be primarily concerned about PCB footprint when selecting a connection, but there are other aspects to consider. Even with knowledge of widely used connections, it is easy to become confused while designing your PCB.

Price:

They are not all equal. Unfavorable financial constraints may force us to redesign our PCB connectors. Consider the connection cost early in the design process to prevent a manufacturing bottleneck.

Polarity protection:

This is vital when working with power connections. As a PCB designer, you must consider the end user’s needs.

If there is a possibility of an incorrect connection damaging the PCB board, polarised connectors should be used. These polarised connectors prevent faulty board connections, reducing the chance of a short circuit.

Rating and temperature:

PCB traces conduct electricity and radiate heat. But a trace’s current and heat dissipation vary greatly amongst PCB boards. When fixing PCB boards, technicians often see burned-out connections.

This is most likely due to inadequate connection selection without considering current flow and operational temperature. As a consequence, the connections melt, and the board fails. Always assess the highest current flow and choose connections that can handle double that amount.

EMI/ESD protection:

To reach greater speed rates, high-speed PCB layouts must safeguard signals from EMI and ESD. This necessitates shielded connections to protect the PCB’s signals. These shielded connections might be more expensive, so designers should factor that in.

PCB EMI Shielding

Dimensions:

Use connections that match your board’s size and purpose. Pitch, spacing, and connection type may all affect the size and profile of a PCB’s connectors. Plan and choose the best one for your board structure and usefulness.

How To Fix A PCB Connector?

If the PCB socket connector is destroyed, it will not operate as it used to. It will result in poor device performance. So you must know how to repair a damaged PCB terminal connector on a circuit board.

The steps are:

Using epoxy

An epoxy resin repair requires a careful application to any broken circuit board connection.

Use the traces

Examine the board for damaged copper traces. And then carefully cut the copper traces with a razor knife.

Getting ready to solder

Next, configure the PCB for soldering to rewire the connector.

Pin PCB Connector

Applying tinning coat

Apply a thin but helpful ‘tinning’ resin layer to the soldering pencil tip.

Using rosin-core

Add rosin core to the exposed copper traces on the PCB.

Using copper wire

Now choose an 18 gauge copper cable. Cut the copper cable to bridge the copper traces using a cutting tool.

Stacking copper wire

Pick up the tinned strands one by one with tweezers. Then arrange the chosen wire on the loose lines you removed recently.

Correctness verification

After finishing the repair, reassemble the gadget and test it. Ideally, yes.

If the equipment still fails, you may have to re-examine the problem and fix it.

How Do You Choose The Right Manufacturer Of PCB Connectors?
