Through Hole PCB Assembly

INTRODUCTION TO Through Hole PCB Assembly

Through-hole assembly is a method for producing electronic circuits in which the components are installed through leads. It is an older technology compared to surface mount.

Although this is an older process, there are some benefits to through-hole PCB assembly. The through-hole mounting process creates a stronger bond between the circuit board and its components, making the product more durable and more resistant to shock and impacts.

Whether through-hole PCB assembly is the right choice (or the only choice) for your application will depend on many factors. Whether you are developing a prototype or manufacturing a product, Kingford can provide comprehensive consulting to help determine the best way to implement it.
