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.


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.

Cable Harness Assembly


Cable Harnesses (Wire harness, cable assembly, wiring assembly) is an assembly of electrical cables or wires which transmit signals or electrical power. Cable harnesses are different from wire harnesses and it is important to understand the difference. A wire is a single conductor, while cables are two or more wires that are insulated being wrapped in a larger jacket. These two technologies demand their own set of unique tools, fixtures, and machinery to help reduce production costs. Knowing exactly what type of product being used is crucial to perfectly create your designs.

·         Wire harnesses generally do not need much to work with and is generally an inexpensive and cost-efficient way for many people to solve their electrical needs. With a single machine, one can increase their production capabilities because of the relative simplicity of wires in general.

·         Cable harnesses are more complex in nature and may require different machinery and tools to be consistent with production. Creating slits and windows in cables demand specialized equipment to handle the various conductors within the insulation

Both technologies are held to the standards like IPC WHMA-A-620 and should be evaluated by their designated class level.

Located in Carson, California, ACME PCB Assembly utilizes top of the line technology from Schleuniger to perfectly cut, strip, and process any wire or cable you need. After 25 plus years in the business, ACME PCB Assembly has the experience to be your contract manufacturer for cable & wire harness projects. As an IPC-A-610 certified assembler with a certified trainer in house, you can be rest assured the cables and wires that come out of ACME will exceed the standards.

You can rely on ACME PCB Assembly for timely, cost-effective service.
