What is Through Hole Technology?

Through-hole PCB assembly is the process of mounting electronic components with leads by inserting them through printed circuit boards (PCB) pre-drilled holes and soldering them to pads on the other side, either manually or using automated insertion mount machines.

The solder joint has several benefits. It’s the actual bond between the board and the components, and its quality equals the connection’s quality.

The solder joint’s appearance is very significant, as it indicates reliability and a strengthened bond.

When the device’s functionality is critical, and/or it is exposed to a very harsh environment during operation, THT is a superior choice.

Benefits of Through Hole Technology

There are many advantages to THT, especially for heavier or bulkier systems and integrations such as semiconductors or electrolytic capacitors in large packages.

Enhanced Physical Connections

–

Able to withstand excess environmental stress

Easy to Prototype

–

Reliable and you can swap out through-hole connections easily.

High Heat Resistance

–

Besides their durability in acute collisions and accelerations, through-hole PCB’s high heat resistance makes them ideal for aerospace and military products.

Better Power-handling Capacity

–

Strong connection between the chip on board and components that undergo high voltage, mechanical stress, and high power, including electrolytic capacitors and transformers.

Upgrade Your Old Technology

New designs commonly use both surface mount and through-hole technologies, rather than relying 100% on either one. Often it makes the most sense to combine the strengths of each technology in one design.

The passive components are surface mount, utilizing the space-saving properties. They can be placed strategically on either side of the board, optimizing the layout for placement and functionality of the device.

Through-hole components are the ones subjected to the most mechanical force. This includes things such as connectors, switches, power and ethernet ports, etc. Any component that has a direct interface with the user would benefit from the added mechanical strength of a through-hole connection.

A thorough review of your product’s design for manufacturing (DFM) can uncover the potential for cost savings and increased performance!
