Does INTA manufacture heat sinks?

Yes, INTA manufactures custom made heat sinks in house to meet customer specifications. Lead times vary but are usually a few weeks. INTA also marks serial numbers for convenience upon request.

What type of heat sinks does INTA sell?

The most common materials are:

Copper tungsten
Copper

Aluminum

 

INTA makes small and tiny heat sinks and related mounts and hardware. INTA also offers raw CuW blanks for customers who prefer to manufacture their own components.

Why are heat sinks important in laser applications?

Lasers, light emitting diodes and other related components generate large amounts of heat which can be detrimental to performance, energy savings, and lifetime. Excessive heat can cause component failure and other problems. Heat sinks carry the heat away from the diode and thereby play an important role in improved performance, extended lifetime and improved reliability for many applications.

Does INTA sell CuW components?

Yes, INTA sells machined CuW components and raw material. INTA also sells CuW electrodes for EDM applications. INTA machines and plates the CuW components at their twin facilities located in Santa Clara.

What is CuW?

CuW is a copper tungsten refractive alloy useful for many applications including heat sinks and electrodes for EDM. There are many varieties and grades including:

W/Cu

75/25

80/20

85/15

90/10

 

The thermal conductivity of CuW is approx 150 W/mK and the CTE is approx 7.1 ppm/deg C. The exact TC and CTE is dependant on grade and forming method. CuW is a powdered metal which is pressed into shape.

Why is CuW used for heat sink applications?

There are many reasons including:

  1. High thermal conductivity
  2. High temperature capability

What about thermal management?

Thermal management calls for heat sinks. INTA manufactures various types of heat sinks. The heat sinks remove heat from delicate components and help improve efficiency, extend product/component lifetimes and improve reliability by helping eliminate failures cause by excessive heat.

Does INTA gold plate copper and/or copper tungsten?

Yes, INTA plates nickel, tin, copper, silver, gold and various other metals onto copper and copper tungsten. Two of the more popular options are nickel and gold.

What coatings are good for tough environments?

The proper coating depends on many factors including the environment the part or assembly will see in testing and in use. Harsh environments can include heat, cold, salt water, thermal cycling, vacuum, etc. Depending on the exact harsh environment, various coatings will be more useful than others. In general, anodizing and similar treatments are very useful but INTA does not perform those steps. INTA uses nickel, silver, gold, rhodium, platinum and several other coatings for harsh environments. Platinum, rhodium and gold are the most protective but often silver or nickel are sufficient. Teflon (performed through a partner, not in-house) can withstand elevated temperatures well and can be used for many purposes in tough environments. In many cases, trial and error and heavy testing is recommended to determine coating suitability. Factors to consider include surface finish, component geometry, coating thickness and others.

Does INTA commonly plate plastic reflectors?

Yes, we plate plastic components, including reflectors. Reflectivity is key and INTA has developed several processes to aid in optimizing reflectivity and cosmetic appearance. INTA also plates special mirrors and other optical components.

Will a gold coated surface reflect a laser beam?

It depends on the beam intensity, spot size, coating thickness, surface finish, grain size, underlying material and other factors but gold coatings can be used for this purpose.
