This issue of
the BEST newsletter breaks from tradition in that this one is
covering a single announcement- the release of a newly-patented solder
preform method for reballing BGAs.------EZReball(TM).
BEST has been
working on this development for over 25 months as various brainstorming
sessions, many trial and errors, on the road with consultants and vendors,
lots of internal product testing in the services area mixed with pure BEST tenacity have made this product a reality. We therefore
decided that the announcement of the our EZReball(TM) solder reballing
preform should stand on its own in this newsletter.
The following
are just some of the values EZReball(TM) brings to the reballing user
community :
Ability to to quickly reball devices
Simplicity of the process
Small minimum quantity purchase requirement with NO tooling charges
for custom patterns
The personal touch of the BEST customer care team
Call us with
questions about the product or the process (or to order your first packet
and have a chance to WIN the GPS!).

Newly
Patented Method for Reballing Devices
The new BEST
EZReball(TM) solder reballing preform provides a new way to quickly and
easily reball devices.
This method
is a quick way to attach balls onto a device. The simple 1-2-3-4 method
as pictured on web site or in our instructional video shows how quickly a device can be
reballed.
The
reballing process using the EZReball(TM) preform can be done very
quickly. After dressing the pads simply place paste flux on the bottom
of the device. Align by squaring up the engineered preform to the
corresponding pads. Place the device into the properly-profiled heat
source. After being cooled simply peel off the preform, clean and
inspect. Its like a Post-it(TM) note with solder balls !
Since
nothing in terms of customized fixtures is required almost anyone can
now reball devices. As long as attention to the process steps, even
those technicians never having reballed a device can attach solder balls
to rework a device!
There are
several compelling reasons why you should begin using these preforms to
reball your devices :
This method
is clean. There are no messy paper remnants to wipe away. Peel the
preform away and clean the flux off of the bottom of the device. The
method is fast . The preforms are cut such that they can be "squared up"
to the package being reballed using the edges of the package for
alignment, thereby eliminating the need to mechanically fixture a
reballing tool to the device. This means you can reball the devices much
more quickly!
The
EZReball(TM) packaging includes a QC stencil along with each package of
preforms. This allows you to easily check for 100% ball placement as
well as facilitating faster rework of single balls
The
EZReball(TM) preform can accommodate ball diameters below 14 mils. BEST
has reballed devices using the EZReball(TM) preform with solder balls as
small as 12mils in diameter with a 0.5mm pitch!
One of the
intangible, yet known values you will get with each EZReball(TM)
purchase is the BEST service level. The BEST staff knows
who pays the bills and we continually strive for the the best in class
customer service. Our award-winning service means that you will be
treated fairly, promptly and with courtesy. You do not have have to
stand for second-class service levels in dealing with a vendor in this
product area. Demand the BEST!
The
EZReball(TM) process had to pass stringent BEST criteria prior to its
release to the general rework audiences. BEST has been using this
technique for several months as part of its reballing service business
having reballed thousands of BGAs already using this technique. In
addition, there are several analytical tests that BEST has performed
that have confirmed the process and end product consistency.
One of the
test results that verified the high level of process yields was verified
in the ball diameter and z axis height measurements. See for yourself in
the link below as the consistency of these two parameters is confirmed
by external lab results directed to in the link below.
