ticularly for coating stainless steel. This is significant because there are few surface treatments that can be applied to stainless steel while still providing the desired functional prop- erties. “DLC coatings provide an ideal combination of low coefficient of fric- tion like PTFE, but with the hardness of a ceramic,” explains Thompson. Surgeons who must perform


under the harsh glare of operating room lighting have also found PVD coatings useful for its anti-glare properties. For example, Oerlikon Balzers’ BALINIT® DLC Medical and BALINIT® C (a WC/C ductile carbide carbon of the DLC family) are black or dark grey, enabling surgeons to work faster and with greater comfort in bright operating rooms.


Semiconductor Manufacturing Oerlikon Balzers’ DLC solu-


tions, such as BALINIT DYLYN, are also used in semiconductor manufac- turing. Here, the coatings are used to endow wafer contact tooling and positioning systems with beneficial


Wilbrecht LEDCO: Small LED Indicator for Thick Panels


St. Paul, MN — Wilbrecht LEDCO, Inc., a Microprecision Electronics company, has introduced a new, longer M6 thread 0.1 in. (3 mm) CDLB series panel LED. This enables customers to design panels with 0.1 in. (3 mm) LEDs to their own specifi- cations, eliminating the need to change to larger LEDs to fit thick panels. The new CDLB series mounts in panels up to 0.3 in. (8 mm) in thick- ness, even when supplied with the optional washer for IP67 sealing.


properties, including low friction, excellent adhesion, and high thermal conductivity, without contaminating the delicate semiconductor wafers. The company tailors the proper-


ties of these DLC coatings to its cus- tomers requirements, in order to reduce the total cost of ownership. High hardness, a low coefficient of friction and excellent wear resistance help to significantly reduce particle formation, enabling high-yield man- ufacturing. One particular example is a new coating from the company that is resistant to etching by fluori- nated chemistries, for applications that include wafers, e-chucks, pedestals, etch kits, shower heads,


and vacuum pump components. To further differentiate prod-


ucts, many manufacturers require customized surface coatings. For this, companies like Oerlikon Balzers have the R&D capabilities to tailor coating solutions to meet unique requirements. In addition to coating thickness and hardness, properties such as structure, chemical and tem- perature resistance, and adhesion can be precisely controlled. According to Thompson, in a per-


fect world OEMs would look into PVD coatings early in the design phase of new products. However, in the real world, many seek out PVD coating solutions only after experiencing

excessive wear, high friction and other issues in early engineering builds. “OEMs often come to us with a


problem late in the design phase- when certain properties, such as the substrate material, may already be locked in,” says Thompson. “Our goal is for customers to start thinking about PVD and PACVD coatings as a design element to fully unlock the potential of this technology and add value to precision components.” Contact: Oerlikon Balzers, 1700

CDLB series panel LED. The front-mount nickel-plated


housing has a prominent bezel shape with a protruded LED. The fully pot- ted housing with additional gasket offers front and rear IP67 sealing and provides environmental protec- tion for outdoor applications. The LED indicator is available


in a broad range of colors and intensi- ties, including daylight-readable, as well as bicolor and blinking. Optional internal resistors allow operation up to 60 VDC. Custom AC voltage assem- blies are also available. Manufactured in the U.S., the LED can be easily adapted to meet custom needs for spe- cial wire, connectors or marking. Contact: Wilbrecht LEDCO,
