How to use wire-to-board connector?

Wire-To-Board Connectors are critical components for electronic devices, as they connect wires to printed circuit boards (PCBs) in hardware products.

Proper Wire-To-Board Connector usage directly affects how well your project works now and in future designs. This article will cover the basics of Wire-To-Board Connectors, including the types of connectors available and where to acquire them, as well as answering frequently asked questions regarding wire-to-board connections.

Understanding Wire-to-Board Connectors

Wire-to-board (or "wire and board") connectors enable you to connect wires directly to PCBs (i.e., Printed Circuit Boards). There is a lot of different types of connectors, and each has a different use and will be used by a different end-user group.

There are several factors you should consider when deciding which type of connector you need (such as connector pitch, connector series, etc.) when choosing a Wire-To-Board Connector.

Because there are so many options for connectors, JST and Molex are the two leading manufacturers of this kind of connector due to the wide variety of possibilities for their application and the diversity in their use throughout virtually all potential applications.

Steps to Use Wire-to-Board Connectors

Using wire-to-Board Connectors effectively requires a few important steps:

Choosing the right series and pitch of your connector is one of the most important factors to consider when selecting a connector for your use case.

You will need to remove 8–10 inches of copper wire from both ends of the wires to create a solid electrical connection when connecting (splicing) the two wires together.

Insert the wires into the connector - Place the prepared wires into the connector according to their designated positions. Properly installed wires must be in their terminals to provide sufficient electrical connection between conducting equipment.

Wire fasteners: The connector's locking device (if applicable) adds additional security to the connection by securing the wire's connection point inside the connector thereby preventing an unintentional disconnection due to force applied to the wire.

You can also use mechanical hardware to connects your connectors (such as screws, clips, etc.) to the printed circuit board (PCB) according to the design. Before connecting the connector to the PCB, ensure that you are aligning the connectors to the holes correctly.

Considerations for Choosing Wire-to-Board Connectors

Here are the decisions that must be made before you select your wire-to-board connector for your application:

Find Out How Much Current Your Application will use (require) to select the appropriate connector.

It is important to verify that the connector being used for your printed circuit board has an appropriate pitch. The connector pins/contacts must be spaced apart (with respect to their center positions) so that they match the spacing of the pads on the printed circuit board. If this is not done, the connector will not work with the printed circuit board.

The selection of effective connectors will rely on the operating environment of the intended application. Therefore, please choose quality connectors that are capable of withstanding such conditions (e.g., high temperatures, humidity, grease, dirt or dust).

FAQs on Wire-to-Board Connectors

Here are some common questions and answers that potential buyers might have:

Which connector pitch or series (e.g., JST, Molex) are you using? There are several types of applications that have different levels of specifications for their development based on what they are being designed to do. One example of this is if you were making an application that you want to run on a certain piece of hardware and the specifications that apply to the device itself. The datasheet for the application you are creating will provide specifications on how to design your app to meet the specifications of the hardware.

What are the advantages of using wire-to-board connectors? You will achieve a reliable system with a fast, inexpensive connection that is easy to install.

Conclusion

Wire-to-board connectors enable wires to be connected to a printed circuit board (PCB) in multiple ways. The proper use of a wire-to-board connector will ensure that you have a strong, dependable connection between the wire and PCB. This reliable connection, therefore improves the overall reliability of your project. Reliable connections give you solid, trustworthy connections between electrical devices, regardless of the environment they are in.
