The Rise of Package on Package (PoP) in PCB Assembly

In the ever-evolving landscape of electronics manufacturing, Package on Package (PoP) technology is transforming how circuit boards are designed and assembled. First gaining traction in the early 2000s, PoP is now considered one of the most innovative advances since the introduction of Ball Grid Array (BGA) components in the mid-1990s.

At its core, PoP is an integrated circuit packaging method that vertically stacks two or more BGA packages—typically combining a logic processor and memory component. This space-saving configuration allows for compact, high-performance assemblies ideal for smartphones, wearables, medical devices, and advanced industrial electronics.

The Advantages of PoP Technology

The primary benefit of PoP technology lies in its ability to reduce external pin count through package-level system integration. By stacking chips vertically, engineers can achieve a smaller footprint without sacrificing power or performance. This simplification not only optimizes PCB layout efficiency but also improves overall product reliability by minimizing interconnect lengths and signal interference.

Depending on the configuration, PoP packages can reach a total height as low as 1.4mm, making them perfect for compact devices where every millimeter counts. Additionally, PoP assemblies support independent testing of logic and memory layers, resulting in higher manufacturing yields and easier defect isolation during production.

ACME PCB Assembly: Leading the Way Since 2009

Since 2009, ACME PCB Assembly has been a leader in adopting and refining PoP technology. Utilizing advanced FUJI assembly lines and precise reflow soldering techniques, ACME delivers reliable PoP BGA assemblies for both prototype runs and medium-batch production.

From single-unit builds to production runs of up to 20,000 pieces, ACME’s skilled technicians ensure precise alignment, solder integrity, and quality control at every stage. This allows clients to seamlessly integrate high-density packaging into their next-generation designs—accelerating time to market while maintaining exceptional performance standards.

Whether you’re developing consumer electronics, industrial control systems, or medical devices, PoP technology offers a compact and efficient solution.

Cable Harness Assembly

ACME PCB Assembly Offers Cable Harness Services

Cable Assemblies include one or more wires that run together in a single sleeve with a connector or plug on each end.  Cable assemblies could be groups of wires or cables bundled together.  They are wrapped in a thermoplastic or vinyl sleeve, cable assemblies are ideal for directing groups of wires and cables around obstacles.

Cable assemblies are designed to perform specific functions that is determined by the plugs, terminals, and connectors that are found on each end.  They are used in most electronic applications, everything from flat panel displays to the automotive electronic system to integrated cockpit systems to simple LED lighted clothing, costumes and accessories.

What Do You Use Cable Assemblies For?

Cable assemblies intersect or interconnect different circuits or electrical paths, so they work together to transmit signals or power.  They usually only have two ends to connect point A to point B.

Ethernet Cable HarnessFor example, ethernet cable assemblies are designed to provide service supporting bandwidth speeds up to 10 Gigabit Ethernet, such as large data centers, military field units, and medical facilities.  For those applications that require a lightweight, smaller assembly that can transmit clearly and rapidly over great distances, support greater bandwidths, with high voltage isolation, then fiber optic cable assemblies would meet those needs.  A few of the industries that utilize fiber optic cable assemblies, include aerospace, automotive, industrial, medical, and military applications.

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.  We

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.
