A heat sink plate is a general-purpose thermal management component that efficiently spreads and dissipates heat generated by electronic devices and equipment, helping to prevent overheating and maintain performance and reliability.
At UPT, we have transitioned the manufacturing of heat sink plates from conventional machining to photo etching technology, enabling greater design flexibility tailored to specific applications. This shift allows for cost-effective, small-lot production, even when multiple design iterations are required. It also makes it possible to process thin plates that are difficult to achieve with machining. As a result, we can provide lightweight, high-performance heat sink plates with short lead times—typically within five days from drawing review to delivery.
If you are facing challenges with heat dissipation or thermal design, you will find thermal solutions at UPT.
High Design Flexibility, Ideal for Prototyping
When heat sink plates are manufactured with conventional machining, frequent design changes during prototyping often require repeated processing, resulting in higher overall costs as the number of prototypes increases.
By contrast, photo etching allows for greater flexibility in pattern design and dimensional adjustments, making design changes easier. This improved process allows prototypes to be produced in small quantities at a more reasonable cost, enabling iterative evaluation while keeping development risks and expenses under control.
Capacity to Manufacture Thin Plates
Photo etching technology is well suited to processing extremely thin metal sheets. Because the process does not apply mechanical stress from cutting or milling, it enables stable and precise fabrication even for thin plates. As a result, it is possible to manufacture lightweight, high-performance heat sink plates optimized for thermal efficiency.
This is particularly important for electronic and precision devices for which miniaturization and weight reduction are critical, and where thermal performance must be secured within a limited space. Photo etching makes it possible to balance compact design with effective heat dissipation.
Short Lead Time
Thanks to our in-house production system, UPT is able to manage the entire process—drawing review, manufacturing, inspection, and delivery—in an integrated manner.
We can often enable delivery within five days of the initial drawing review. During prototyping and evaluation phases, when quick feedback is essential, such responsiveness can help shorten overall development timelines.
UPT’s Thermal Solutions
In addition to heat sink plates, we offer a wide range of thermal solutions. We propose the most suitable solution based on each customer’s requirements, so please feel free to contact us for a consultation. Below are some examples of products we have manufactured.
Cold Plate
Cold plates are indispensable cooling solutions for electronic equipment and semiconductor devices. At UPT, we integrate photoetching technology with diffusion bonding to produce cold plates that deliver maximum cooling performance.
Water-Cooled Heat Sink
A water-cooled heat sink is a cooling solution designed to efficiently remove heat from electronic equipment and computer CPUs. By combining photoetching technology with diffusion bonding, UPT can maximize the cooling performance of these components.
Small (Thin) Heat Sink
UPT manufactures small (thin) heat sinks with microchannel structures using an original production method that combines photoetching and diffusion bonding technologies. Despite their compact and thin design, these heat sinks provide high heat dissipation performance.
