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.

Flexible Circuit board

Flex Turnkey PCB Assembly

The design rules for flex turnkey PCB assembly is very similar to the design rules for traditional PCBs.  Traditional PCBs and flex flex turnkey PCB assembly share some similarities in the manufacturing process as well.  To start, the flexible circuit board material (typically copper clad Polyimide) is chosen, drilled, plated, photo-imaged, and imprinted just like the conservative PCB process. Next, both PCBs and flex turnkey PCB assemblies involve the panels being baked to remove any moisture from the wet processes.  This next step is where the original PCB and flex turnkey PCB assembly start to differ.  Flex turnkey PCB assemblies go to the cover lay station instead of going to the fuse mask station, as would occur with traditional PCBs.

A flex circuit board cover lay, also known as a cover film, is a lamination process used to summarize and protect any peripheral circuitry of the flex circuit. The cover lay serves the similar function as the solder mask does for conventional PCBs with the dissimilarity being the added component of flexibility. Naturally, the thickness of the cover lay is prepared of 1 mil thick Polyimide with a 1 mil thick, attach adhesive, but other thicknesses are accessible to meet precise design necessities. The Polyimide and adhesive cover lay is laminated using force and heat.

Flexible circuitThe heat allows for simple flow of the adhesive which is needed because it must fill-in any and all gaps among the traces and pads to stop the trapping of air between layers. To a flex turnkey PCB assembly designer this means the cover lay openings for a characteristic 1 oz. The copper plan must be out-sized by 10 mils, which is appreciably bigger than the typical huge of 2-3 mils used on conventional PCB solder masks.
