Thanks largely to the historic CHIPS and Science Act of 2022, semiconductor CNC machining has made tremendous progress throughout the United States. To support this booming industry, American Valmark has added countless new modernized machines, experienced personnel, and renowned certifications to become a leading provider of semiconductor CNC machining services in Texas. These precise components are essential to nearly all aspects of electronic technology and take immense skill and engineering insight to craft. American Valmark excels at producing premium-quality, tight-tolerance semiconductor parts at competitive prices and fast turnaround times. This article looks at the finer details of semiconductor CNC machining, why American Valmark succeeds in the sector, and what the future holds for this exciting industry.
What is Semiconductor CNC Machining?
Semiconductor CNC machining is a process that uses computer-controlled machines to create highly precise and complex parts used in the semiconductor industry. These machines operate using programmed instructions that guide tools to cut, drill, or shape materials with incredible accuracy. The parts being produced often include heat sinks, wafer handling components, precision enclosures, and specialized connectors. Considering that these components are used in sensitive electronic devices, they need to meet extremely tight tolerances, and even the smallest flaw can affect performance or cause a failure. CNC machining is valued in semiconductor manufacturing for its consistency, efficiency, and ability to work with a wide range of materials while maintaining the precision required for critical applications. In addition to the standard metals, American Valmark has expanded its machining capabilities to include non-metal materials such as Delrin, Ultem, G-10, Teflon, and PEEK.

Real World CNC Machining for Semiconductors
American Valmark recently machined a complex set of aluminum end effectors for a demanding high-performance semiconductor application, requiring the company’s expertise in meeting tight tolerances and solving difficult design and manufacturing challenges. Several key aspects of the project included:
- Extremely thin wall geometry → Thin wall geometry requires carefully planned toolpaths and specialized fixturing to control chip deflection and prevent distortion during machining. Maintaining structural integrity throughout the process was essential due to the delicate nature of the features and to avoid expensive material waste and rework.
- Tight-tolerance internal channels → Designed to route small-gauge wiring, these channels had to hold precise dimensional fits across multiple features. This called for close attention to the proper selection of cutting tools and closely monitoring tool wear to ensure consistency throughout the run.
- Critical threaded holes → Threaded holes need to be masked before hard black anodizing to protect thread integrity. Any overspray or buildup would have compromised the fit and function of the final product, so masking and post-finish inspection were tightly controlled.
- Flatness within ±0.002″ → Achieving this level of flatness on the mounting surfaces required careful sequencing of machining operations and inspection at multiple stages to ensure stability and compliance.
- Parallelism within ±0.002″ → This was vital for proper alignment in the customer’s downstream assembly process. Precision workholding and real-time verification during machining helped maintain this strict requirement.
This semiconductor CNC machining project illustrates American Valmark’s strength in high-precision machining, complex workholding, and coordination of finishing processes for advanced components used in sensitive, performance-critical environments.
Why American Valmark Leads Texas in Semiconductor CNC Machining
Texas is now the number one state for semiconductor manufacturing in the nation and is home to some of the largest companies anywhere in the world.
