The benefits of parylene deposition for implantable medical devices
MDDI
Parylene provides precisely deposited protective conformal coatings for medical implants, enabling the specific device purpose despite challenging physical configurations. Other performance properties amplify parylene’s ability to withstand operational duress throughout surgical implantation and long-term use in the body.

Vacuum advances in biotechnology
Vacuum Coating & Technology
Surface characterization of materials presenting biological and/or biochemical interfaces (i.e. bio-interfaces) are of great interest for medical and pharmaceutical industry. Bio- implants, anti-fouling properties, and other biomedical or diagnostic devices are some of the new and emerging biotechnologies that are based on solid-liquid bio-interfaces that need fundamental understanding and knowledge of such bio-interfaces for better functionality of diagnostic devices.

Coatings expand cutting tool capabilities, reach new markets
ADVANCEDMANUFACTURING.ORG
When first introduced in the late 1970s, cutting tool coatings — especially titanium nitride (TiN) — were embraced by tool manufacturers for their ability to extend tool life. As workforce materials have expanded from conventional ferrous and nonferrous metals to exotic alloys, composites, ceramics, and others, coatings have likewise progressed and, thanks to new formulations and deposition methods, are extending cutting tool capabilities as well as tool life.

TECHNICAL TIPS


What you need to know about aluminum evaporation
Aluminum is a very popular material for evaporation. We have many different sources that can be used to successfully evaporate aluminum. However, there are a few common problems that occur when evaporating this material. One problem that you may be aware of that aluminum wets to most surfaces and does not stay in the evaporation area. The other, more significant problem is that moltent aluminum is very corrosive and will corrode through most surfaces and cause the boat or box to break during the evaporation process. Spitting is not normally a problem. Tungsten is the most resilient of the materials to this corrosiveness. Below are some things to consider when choosing the right source for your application:

A) What is the maximum current you have available to apply to the source?
B) How thick of a coating are you attempting?
C) What is the distance from the source to the substrate?
D) Are you evaporating in an upward direction?
E) What length source will fit in to your mounting points?

After reviewing the information above, you may be able to select the right source for your process. If you need further assistance, please do not hesitate to contact us.
