Is Through-Hole Assembly Still Important to Use?

 

Before the 1960s, the through-hole assembly process for mounting components onto printed circuit boards was the only game in town. It was labor-intensive and required a lot of space, but it was the only option. That all changed with the rise of surface mount technology (SMT), which allows for components to be mounted directly onto a printed circuit board’s surface. Since SMT doesn’t require drilling holes through a PCB, its components are much smaller and can be mounted on each side of the board. The result is a denser, smaller PCB that can perform much better than a PCB using through-hole technology.

When SMT came on the scene, many engineers believed it would harken the death of through-hole PCBs. However, while SMT does reign supreme, through-hole is still with us today. In very specific circumstances, through-hole PCBs are a better choice than their SMT counterparts.

A Few Important Uses for Through-Hole PCBs

Through-hole PCBs may be bigger and clunkier than SMT PCBs, but they do offer up one important advantage. Through-hole components are attached far more securely than SMT, which gives them a much stronger connection between layers. SMT connections are strong enough for the vast majority of products that people use in their day-to-day lives, but for machines that must operate in extreme environments, through-hole is the more reliable and stable option.

For example, through-hole PCBs can be commonly found in machines in the military and aerospace industries. Oftentimes, these machines must survive extreme temperatures, forceful collisions, and rapid accelerations. Through-hole is the ideal reliable and resilient mounting option for these types of products.

Prototypes

The other area where you are most likely to find through-hole mounting is in product prototypes. Through-hole is often preferred in prototyping, because it is much easier to adjust and replace components as the prototype undergoes testing and design alterations. If you are dreaming up an exciting new product, you’ll want to reach out to a printed circuit board vendor that is adept at through-hole mounting. This will give you more flexibility as you put the prototype through its paces.

Find Your SMT and Through-Hole Vendor

No matter what your industry or product line, it is smart to look for a printed circuit board manufacturer with both SMT and through-hole experience. This will allow you more choice and more control over your final product. At ACME PCB Assembly, we offer extensive experience in both SMT assembly and through-hole assembly.

How to Choose the Right PCB Material for Your Application

When it comes to electronic products, the materials you choose for your printed circuit board (PCB) can make all the difference in performance, reliability, and even cost. Selecting the right PCB material isn’t just about picking what’s readily available; it’s about matching the material’s properties to your specific application. At Board Assembly, we understand the importance of PCB material selection and are here to help you navigate the options.

Why PCB Material Matters

Your PCB is the backbone of your electronic device. It carries electrical signals, manages heat, and supports all your components. The wrong material choice can lead to issues like signal loss, overheating, or even mechanical failure. That’s why understanding your project’s requirements is key to making the right choice.

Factors to Consider

  1. Thermal Performance:
    If your application generates a lot of heat—like in power electronics or LED lighting—you’ll need a PCB material with good thermal conductivity. Materials like aluminum-based PCBs or high-Tg FR-4 are excellent choices.

  2. Electrical Performance:
    For high-frequency or RF applications, you’ll need a material with low dielectric loss. PTFE-based materials are often recommended for their superior electrical properties.

  3. Mechanical Strength:
    Will your PCB be exposed to vibrations, shock, or mechanical stress? If so, choose materials with higher mechanical strength to avoid cracks and failures.

  4. Cost:
    Budget matters too. While advanced materials like Rogers or ceramic substrates offer excellent performance, they can be pricey. For many applications, standard FR-4 remains a reliable and cost-effective option.

  5. Environmental Conditions:
    Consider the environment your PCB will operate in. Will it face moisture, chemicals, or extreme temperatures? Some materials offer better resistance to harsh conditions.
