Heat in the handle despite high gear density

Trends like digitalization would be virtually inconceivable without the miniaturization and high circuit density of printed circuit boards (PCBs). Equally essential is their efficient heat dissipation: it protects against overheating and thus ensures the functionality of the electronic components on the board. CTX Thermal Solutions achieves this with a wide range of heat sinks for PCBs.

The demand for PCBs is enormous. According to the market research company Research Nester, the value of the global PCB market is expected to rise from an estimated US$78.18 billion in 2025 to over US$130 billion in 2035. Key drivers include electromobility and the Industrial Internet of Things (IIoT), whose processes require sophisticated PCBs. This also increases the need for high-performance PCB heat sinks, such as those supplied by CTX Thermal Solutions for these and other applications.

Cooling of various components

CTX's standard portfolio alone comprises several hundred different models. This means the manufacturer from Nettetal covers a wide range of Rth values ​​from 6 to 72 °C/W. With a broad variety of designs, CTX can cool a wide range of electronic components. The product line includes, among other things:

• Clip-on heat sinks for TO-220 and TO-218 semiconductor packages
• Extruded SMD heat sinks
• Stamped low-profile heat sinks for D-PAK (TO-252), D²PAK (TO-263), and D³PAK (TO-268) packages
• Profile heat sinks with integrated solder pins for wave soldering on the circuit board
• Solderable, clip-on, or screw-on finger, snap-on, or small heat sinks for TO-5 or TO-18 packages.

In addition to standard heat sinks, CTX also develops and manufactures custom cooling solutions. Production typically takes place using sheet metal bending, extrusion, or die casting.

Secure Mounting Included

Besides cooling performance, installation space, and required quantities, the mounting of heat sinks on the circuit board is another important factor that CTX considers in its cooling solutions. Finger-type heat sinks are equipped with solder tabs, while screw-mounted heat sinks feature threaded connections. Mounting clips and springs are the most common mounting methods for extruded PCB heat sinks, as they facilitate the rapid assembly of even large quantities. CTX offers its own line of clips and springs, characterized by raw materials from certified manufacturers and in-house hardening processes. This allows CTX to supply PCB heat sinks and mounting hardware completely from a single source.
