We are pleased to announce the arrival of BEST Inc's newest
capability. Several weeks ago we installed and commissioned a new
batch cleaning system for PCBs and BGAs. With the addition of this
capability, BEST can now insure faster turnaround times for projects
requiring cleaning and better results as flux can be cleaned sooner
after being reflowed. For those of you who have water-based
chemistry fluxes you can now consider bringing rework projects to
BEST. Be sure to check out the solder spinning video, whose link
is found in the article below for something interesting!
For those of you in the Wisconsin and Northern Illinois area, be
sure to sign up for SMTA Wisconsin Vendor Day to be held in suburban
Milwaukee on November 7th. Not only be there be some good speakers
covering topics such as design for manufacturability and lead free
inspections standards, but there will be a microbrew tasting
afterwards with the first 100 attendees will receive a commemorative
mug! The link to the signup page is listed below.
Hope to see you there!

StencilQuik(TM) Repairs Mask Damage |
 |
StencilQuik(TM) can save you the many tedious hours involved
in repairing mask damage underneath BGAs. After removal of a
BGA the solder mask may be damaged when wicking braid is
used to remove residual solder. If this is the case, there
is no need to repair the solder mask. The StencilQuik(TM)
stencil will prevent the solder from migrating down the "dogbones"
to the vias. The two 2-dimensional X-Ray images that
follow Clearly demonstrate the mask Repair properties of
StencilQuik(TM). In both cases the mask was completely
stripped from two test vehicle boards. The first image shows
the ball patterns of a BGA reworked using StencilQuik(TM).
Note the uniformity of the solder ball patterns. In the
second image a traditional metal stencil was used to apply
the solder paste pattern to the board. Note the areas in
which solder shorts occurred and where the solder went down
the dogbone to the via, thereby starving the solder joint.

New Batch Cleaning Capability |
|
|
BEST is proud to announce the addition of a closed-loop
fully automated batch cleaner for cleaning water soluble
fluxes. This cleaner now brings in house capabilities for
cleaning BGAs after reballing as well as the ability to
fully clean circuit boards after rework to a defined
cleanliness level.
This automatic de-fluxing system provides cleanliness levels
exceeding all military, IPC, and other high-reliability
specifications. It uses a washing technology that ensure the
removal of flux and other contaminants from even the most
difficult circuit assembly.
It is also equipped with on-board cleanliness testing
capabilities. Desired cleanliness levels may be programmed
to ensure consistent cleanliness standards are met. Also
available from the Expanded Statistical Process Control (ESPC)
software is exportable SPC data for process monitoring and
tracking.
Please call Laura Ripoli at extension x33 if you have a
cleaning project or further questions about this machines'
capabilities.

Local Boy Does Illini Proud |
|
|
Steve Chen, 28, who grew up in northwest suburban Prospect
Heights, is an Illini (computer science), Hersey high school
and Aurora Mathematics School grad, sold his (along with his
partners') wildly popular online video sharing site to
Google for $1.65 billion. The company, which bosts 100
million movie clip viewers each day, started in a garage
less than two years ago. It was housed above a pizza place
and survived on a shoestring budget.
Google is betting that online video ads will be a $1.3
billion business by 2011, or four times what they they are
today.
Already there have been some successful ads on YouTube. Ecko
Clothing, a Florida-based apparel brand for young urbanites,
recently posted a commercial on the video-sharing site. It
featured a graffiti artist defacing Air Force One and was
designed to look like a homemade video. The spoof reached an
estimated 135 million consumers, including ones who viewed
it online and others who read the media coverage that
followed. For a relatively unknown company like Ecko, that's
a huge payoff. By way of comparison, the finale of last
season's most popular TV show, "American Idol," drew about
36 million, or almost a quarter of that.
See this spinning solder flux video here.....the
convection cell set up by the solder being heated from the
center, thanks to the wire its mounted on, is able to start
the whole ball of solder flux spinning. The lack of gravity
frees up the solder to the cell has the strength to start it
spinning. See this video
