In Which PCBs Through Hole Technology is Used?

There has been a steady rise in the electronic business as more and more people use electronics in their daily routines and routines. The PCB market is growing in tandem with the need for advanced and smaller goods. PCBs are becoming smaller than ever before. Circuit boards are difficult to work with because of their compact dimensions.

For this reason, manufacturers are employing two methods for attaching circuit board components. These approaches are Plated Through-hole Technology (PTH) and Surface Mount Technology (SMT). PTH is among the most used ways for mounting electrical components to the PCB, such as microchips, resistors, and capacitors.

The wires are threaded through predrilled holes and crisscrossed on the other side with this method. Do you want to learn more about the advantages of employing plated-through hole assembly when building circuit boards? You can learn more about these circuit boards by reading this blog post.

What is Through Hole Technology?

Through Hole technology is a method for constructing electronic circuits in which the pin-through hole (PTH) components are inserted through holes drilled into printed circuit boards (PCBs). The ends, or leads, are then affixed to pads on the opposite side with molten metal solder using wave soldering or reflow soldering equipment. This process is also called through-hole assembly.

Through-hole technology replaced early electronics assembly techniques such as point-to-point construction. From the second generation of computers in the 1950s until surface-mount technology became popular in the late 1980s, every component on a typical PCB was a through-hole component.

Another benefit of using a through-hole is for high-power designs. Circuits that operate at high currents may require a larger, more robust solder junction than a surface-mounted one. A heat sink, commonly utilized with high-performance components, can add considerable weight. If these components are soldered onto a surface, the heat required to do so may be too great for a surface-mount soldering junction. Due to the limitations, larger components used in high-power applications cannot be housed in a surface-mount package.

Manufacturing

Surface-mount components are perfect for automated assembly processes, but manual soldering of through-hole components is far more convenient for industrial workers. Therefore, through-hole parts are a good choice for prototypes and other low-volume manufacturing runs that require manual soldering.

Additionally, if a component needs to be desoldered to be corrected or replaced, through-hole components are simpler to rework if you’re doing a project independently, whether at home or work; a through-hole part is a way to go.

However, despite surface-mount components dominating circuit board manufacture, through-hole components will remain essential. These components are far from obsolete, and they will keep playing a vital part in circuit board production for a long time. Through-hole elements are also required in older designs, for example.
