Coatings World - October 2010

mulation of Trinar Aqua air dry system (ADS) coating was developed in partnership with AkzoNobel. This new, on-site finishing option from Linetec helps preserve commercial and residential properties' green goals, as well as performance and aesthetics. The water-based Trinar Aqua ADS was created to meet the interior specifications for the Green Seal Standard and the U.S. Green Building Council's LEED (Leadership in Energy and Environmental Design) Green Building Rating System, offering very low-VOC content. As a fluoropolymer finish, Linetec's application of Trinar Aqua ADS meets weathering requirements of AAMA 2605, the most stringent specification for architectural coatings. Finishes of this quality are the most resistant to humidity, color change, chalk, gloss loss and natural weathering of any coating available today.

HENKEL DEVELOPS
ABLESTIK WBC-8901UV
Recognized for its ease of use and cost-
effectiveness with die attach processes
for leadframe packages, Henkel has
extended its Wafer Backside Coating
(WBC) portfolio to also include a solu-
tion for stacked die packages. Ablestik
WBC-8901UV has been designed to
address the demanding requirements of
multiple die stack applications for the
memory market segment, including
packages such as TSOPs, MCPs and
FMCs (Flash Memory Cards). The
unique formulation of Ablestik WBC-
8901UV offers a robust and cost-effec-
tive alternative to current film-based
solutions for die stacking processes,
reducing the total cost of ownership as
compared to film by as much as 30% to
50%. Process flexibility is also
enhanced, as packaging specialists can
now adjust die attach thickness based
on specific manufacturing require-
ments and can also select their dicing
tape of choice. Film die attach materials
are generally supplied in predeter-
mined thicknesses as a bundled product
which incorporates the dicing tape.
Applied via a spray coating method fol-
lowing the wafer thinning process,
Ablestik WBC-8901UV is precisely
deposited across the back of the silicon

New Products wafer following which the material is B-staged using a UV irradiation process. After this step, dicing tape is laminated to the wafer, backgrinding tape is removed and the wafer is diced in preparation for die pick-up and placement. Henkel is currently partnering with spray technology and backgrinding equipment manufacturers to deliver an integrated, inline process solution for this unique WBC advance.

NEW ANTI-STATIC COATING FOR PLASTICS Performance Coatings International (PCI) has introduced Vueguard 941 anti-static coating for plastic products required to dissipate a static charge. Vueguard 941 is a crystal clear, solvent-based UV curable coating that maintains optical clarity on molded plastics. It is designed for applications where a permanent, clear coating is required to dissipate or prevent a static charge. A typical use would be to prevent static build-up on a personal electronic display. Vueguard 941 can be applied via spray, dip, spin, roll or flow coating. CW
