Why do we still employ through-hole technology to create PCB assemblies, when SMT boards are typically smaller and cheaper?

Hello everyone, today let's disuss the reason why we still use the through-hole technology!

Through Hole mounting is inserting component leads into drilled holes in a bare #PCB. Through-hole technology was the accepted configuration approach in the industry prior to the introduction of SMT in the 1980s. Many think that THT will become outdated because Surface Mount is less expensive and more efficient.

However, despite its drop in ratings over time, the Through Hole technique has been demonstrated to be resourceful in the age of SMT, providing numerous benefits and specialty implementations. Durability is the most notable advantage of through-hole technology, and currently, annular rings establish a durable connection.

#Through hole assembly with simple components is largely used on products such as power supplies, computer mother boards, security alarms, cleaning equipment and LED lighting products.

For many contract manufacturers, through-hole PCB assembly is a distraction from their higher-volume SMT business. However, since many applications require through-hole components, you should be aware of your contract manufacturer's capacity to handle them. ?

?At #STHL Technology, skilled workers perform fast and quality THT assembly process for our customers. Our Lead Free wave soldering offers customers ROHS standard projects. With 2 THT assembly lines and 2 post soldering lines, STHL Technology can offer both low volume and high volume through hole assembly service.
