"Make" versus "Buy" decisions happen
on a nearly daily basis in business.
One of these type of decisions EMS
providers or OEM manufacturers of
electronics assemblies faces is that
of reworking and repairing circuit
boards. In this newsletter we point
you in the direction of a few
helpful tools in making this
decision.
We also welcome Laura Ripoli to the
BEST staff. Laura brings with her a
vast experience in serving customers
in the electronics industry. She is
a welcome addition to the BEST team.
Bob Wettermann, President
Rework Calculator
When determining actual
rework costs, it is always a
good idea to consult with
your accounting department.
You should obtain from them
a "fully burdened" overhead
rate per rework associate
that can be used as a basis
for your calculation. Work
with them to obtain the cost
of equipment and training.
Make sure that you get a
handle on scrap costs, which
in many cases is the largest
single component of total
rework cost.
Once you have calculated the
costs required as inputs to
the cost model, you can
calculate the costs of a
rework job. BEST has
worked with a cost
accounting firm to develop
and research national
averages as default values
to this model.
Use this tool to help you
make well-informed "make" vs
"buy" decisions in terms of
rework projects.
Solder "Rinsing" Technique
for Maintaining RoHS
Compliance
A new technique which allows
you to use the SAME
soldering tips in a mixed
alloy environment has been
developed by BEST. BEST's
newly developed "rinsing"
technique allows you to stay
within the RoHS guidelines
for rework even when
switching between lead-based
and lead-free solders.
The study, which measured
the presence of lead on the
tip after subsequent "rinsings",
found that a (4) time rinse
sufficiently can reduce the
lead content to below the
RoHS 0.1% lead by weight
guidelines.
Laura Ripoli, a seasoned
very capable veteran of the
electronics industry, has
joined BEST. In her most
recent capacity she managed
an electronic components
business, dealing with
vendors, end users,
distributors and OEMs. Laura
has over twenty years
experience in the
electronics industry. Her
primary focus over the past
14 years has been Inside
Sales/Customer Support at mL
Technologies. This included
sales support of customer
orders on a direct basis,
and thru the distribution
channel. Laura’s previous
jobs included positions at
Arrow Semi (Product Manager)
and Tek-Aids Industries
(Customer Service Manager).
Laura is responsible for
managing your rework and
repair as well as prototype
build projects from initial
contact to through shipment.
The staff at BEST has
developed a variety of
visual aids to help BEST
soldering techs make the
transition to a "mixed"
facility which includes both
tin-lead as well as "lead
free" hand soldering
operations. These cue cards,
t-shirts, work orders and
posters all have the common
theme of using red and green
colors to differentiate tin
lead from our "lead free"
work.
The color coding is a
quick way to remember the
meaning of the two slogans
"RED IS LEAD" and "GREEN IS
CLEAN" (trademark pending).
For instance a RED sticker
on a work order indicates
that the solder alloy and
process to be used is
lead-based. A GREEN sticker
indicates the
environmentally-friendly
"lead free" solder and
process is to be used. If
you would like a sample card
as a means to help remind
your staff please call
Laura Ripoli at (847) 797-
9250.
