Introduction

If our standard series heat sinks do not meet your needs, we can create custom heat sinks at reasonable cost and lead-time. Please review the following guidelines regarding custom heat sinks.

There are two major custom design level.

• Utilize existing design
  • Typically, no tooling fees are required.
  • Suitable for low-mid quantity usage.
  • We can cut, drill, make machining or wire EDM/EDM our existing standard heat sink.
• New tooling
  • Fin(pin) configuration, base size and shape can be virtually anything.
  • Suitable for mid-high volume custom parts.

Utilize existing design(Custom Modification to our standard heat sink)

Typically, the following modification can be done without making new tooling:

• Height change
• Base thickness change
• Cut base size (between fins(by machining) or EDM cut)
• Fin remove (some fin pattern may be difficult to remove)
• Holes/Tapped Holes (not interfere with fins)

You can download our catalog parts drawing(DXF format) from our web site. Please feel free to contact us if you need for our help.

New tooling

Custom tooling is warranted when there is no way to create the desired heat sink from our standard series. This would include fin pattern, base geometry, or features like threaded holes or standoffs. Tooling would also be warranted if a part could be made by machining an existing standard series, but is being used in high enough quantity to see a unit price reduction by tooling.

Once a part is tooled, secondary machine work is minimized, as well as wasted material. Alpha will maintain the tooling for the life of production at no added cost. Also, many different heat sinks can be made from one tooling. The base thickness and overall height can adjusted without having to modify the tooling. A 10, 20, and 35mm tall heat sink can all be made from the same tooling with no modifications required. (Please visit Heat Sink Design for MicroForging® as well)
