Hand Soldering: Why It’s the Right Call For Your Electronic Manufacturing PCB Assembly

Hand Soldering: Why It’s the Right Call For Your PCB Assembly Through-Hole

Through-hole assembly, once the most common electronic manufacturing and assembly technique, has become rare in a world where tiny components with many connectors are the norm. Through-hole assembly is an excellent choice for producing a high-quality PCB assembly, but it cannot perform well when small size is the top priority. In some instances, particularly in unpredictable or extreme environments where high reliability is important, through-hole assembly is still the best way to go.

What is Through-Hole Assembly?Legacy - Square

Through-hole assembly is a manufacturing method where small holes are put into the circuit board and leads are threaded through to the opposite side. Once the leads are threaded, they are soldered into place. This method must either be done using a wave-soldering machine, or by hand.

Though it is a very reliable assembly technique, through-hole lost some practicality when circuit boards started getting very small to accommodate smaller and lighter technology. There is only so much space on a circuit board, which limits the number of holes and components that can be assembled on it.

However, there are still instances where the disadvantages of through-hole assembly for your PCB assembly are either of no concern or they are eclipsed by through-hole’s superior reliability.

Current Uses for Through-Hole Assembly

In military and aerospace PCB assembly applications, for example, safety and durability are of the greatest importance. Additionally, these industries present a range of extreme environments, temperatures, and other stressors that an assembly must be able to endure without failure.

Through-hole assemblies may take up more space than other assembly techniques, but they also create a stronger and more reliable bond. Because of this, through-hole assembly remains a preferred choice for military and aerospace applications.

So while through hole assembly might seem like a dinosaur technique against the current electronics market, there is definitely still a place for it where durability is most important.

Quality Certifications with Through-Hole Assembly

Fortunately, Levison Enterprises provides through-hole assembly and invests heavily in maintaining a high-quality standard for every product, through-hole or not.

Levison Enterprises proudly maintains AS9100, ISO9001, IPC, and J Standard certifications. The maintenance of all these standards ensures a quality product and one that adheres to the highest safety and workmanship demands in manufacturing.

AS9100 is used by the aerospace industry to apply a highly stringent quality standard. Here at Levison Enterprises, we maintain this demanding set of standards and apply it to all assemblies we complete, regardless of the industry in which they will be used.

ISO9001 is a broadly recognized certification that relates to customer satisfaction and regulatory requirements. Levison Enterprises fulfills the requirements of this certification from safety and quality to communication with our customers.

Finally, the IPC and J Standards relate specifically to workmanship for cables and circuit board assemblies. These international standards are highly regarded within electronics manufacturing and Levison Enterprises works hard to stay at the forefront of every quality benchmark provided within both standards. We believe in this so thoroughly that the entire production staff at Levison Enterprises is IPC J Standard certified for soldering and inspecting up to IPC-A-610 standards.
