When replacing obsolete integrated circuits, the primary goal is often functional compatibility. Engineers want a replacement that behaves like the original part. However, advances in packaging technology, materials, and thermal management mean there is now much more that can be achieved.
At Force Technologies, we specialise in managing the complete process of custom IC packaging, from initial design consultation through to final test and delivery. While the electrical function may remain the same, packaging improvements can lead to significant gains in reliability, longevity, and environmental performance.
Packaging Materials Have Evolved
Many legacy components were built in plastic packages such as PDIP or PLCC. These were standard at the time, but they offered limited protection against thermal stress, mechanical strain, or environmental exposure.
Today, it is possible to specify replacements using ceramic packages and metal-glass sealing. Ceramic offers improved thermal conductivity, greater mechanical strength, and better long-term stability. Hermetic sealing also prevents moisture ingress and corrosion, helping to ensure long-term reliability even in challenging conditions.
These modern packaging methods allow us to offer equivalents that match the original form and pinout, but with enhanced durability and thermal performance.
Better Thermal Management Without Changing the Die
Packaging now plays a far more important role in thermal performance than it once did. Many legacy systems were not designed with heat dissipation in mind, but today’s expectations are different.
Force Technologies Limited can specify packaging options that improve heat dissipation through features such as metal lids, thermal paths, and ceramic substrates. These design choices reduce junction temperatures and help increase the life and stability of the component without any changes to the silicon itself.
Reproducing Obsolete Package Types
As legacy devices reach end-of-life, original package styles are often no longer available. Force Technologies can manage the replication of rare or discontinued packages, including CQFPs, flatpacks, and custom hybrid formats.
In many cases, the replacement part offers not only the same electrical and mechanical fit, but a more robust construction overall. Advances in bonding, sealing, and material quality help ensure that the modern equivalent outperforms the original, even in critical applications.
What Has Changed And What Can Now Be Achieved
With over 40 years of experience supporting high-reliability applications, we help clients understand how packaging technology has changed and what that means for their legacy systems. We provide guidance on how performance, resilience, and longevity can be improved, even when electrical functionality stays the same.
Clients often come to us looking for a direct replacement. What they receive is a fully managed solution that not only meets original requirements, but in many cases enhances them.
However, there can be cost implications. Ceramic packaging, hermetic sealing, and advanced assembly methods are more complex and carry a higher unit cost compared to older plastic-based options. That said, the long-term advantages including improved system uptime, reduced failures, and extended support often justify the investment.
A Fully Managed Solution
Force Technologies manages the entire process from start to finish, a one-stop for your needs, covering package design, component assembly, testing, and final delivery. Whether the need is for a single prototype or a production-ready replacement, we provide continuity, technical oversight, and a quality-assured path from concept to completed part.
Custom IC packaging is no longer just about form and function. It is a tool for improving reliability, extending system life, and enabling long-term support for discontinued components. With decades of experience and a fully managed service offering, Force Technologies helps customers move beyond basic replacements and toward better-performing, longer-lasting solutions.
