EGV is Federal Signal’s Supplier of the Year
Vietnam Facility’s System Strategy Cuts Time, Cost
SigmaTron International’s Elk
Grove Village (EGV), IL facili-
ty was named Supplier of the
Year by Federal Signal. The
facility builds printed circuit
board assemblies (PCBAs)
and electro-mechanical subas-
semblies for this customer.
There are over 100 different
product types.
“This project has been a good
example of the level of part-
nership that can be achieved
when customers and our team
work together to discuss pro-
ject goals and the best path to achieve them,”
said Jim Barnes, the EGV facility’s Vice Presi-
dent of Operations.

Low cost doesn’t translate to low use of tech-
nology in SigmaTron International’s facility in
in Biên Hòa, Dong Nai province, Vietnam.
Its systems strategy is focused on four key
areas:
 Minimizing non-recurring engineering ac-
tivities
 Eliminating defect opportunities
 Enhancing internal, supply chain and cus-
tomer visibility throughout the product
realization process
 Maximizing economies of scale by linking
with centralized procurement and engi-
neering resources
“We’ve had ERP system linkage since 2012
and have been adding internally developed
systems over the last year. Today, we utilize a
mix of standardized system platforms com-
bined with a suite of internally-developed
software tools to support areas the core off-
the-shelf systems don’t handle as well. We
believe that systems cost is easily offset by
reductions in engineering labor, excess inven-
tory and cycle times, said Peter Sognefest,
the facility’s General Manager and Director
of Operations.
The facility has transitioned to an automated
data transfer process. This reduces the po-
tential for manually-induced errors in docu-
mentation transfer and programming, plus
the overall time required for new product
introduction (NPI) activities. Bills of material
(BOMs) are loaded into a Macola ES ERP
system to drive materials acquisition. All
documentation is also released into an Agile
Product Lifecycle Management (PLM) system,

 Finished Goods (FG) Kanbans: The
majority of the assemblies are re-
leased under FG Kanban programs.
The inventory is replenished as con-
sumed and adjustments are made when
demand trends change.
 Linkage with Supplier Self-Service
Website: Kanban releases, confirma-
tions and forecasts are accessed
through the customer’s website. EGV’s
team also updates the customer’s plan-
ners weekly on work-in-process (WIP),
FG and estimated time of arrival (ETA)
via this portal.
 Customized Reports: EGV’s team has
created customized color-coded re-
ports that the customer uses to track
defined metrics of on-time delivery
(OTD) based on combined inventory
levels.
 Efficiency Improvements: SigmaTron
(Continued from page 1) and Federal Signal have partnered to
find ways to streamline daily opera-
tions such as redefining Kanban sizing
and identifying slower assemblies to
remove from the Kanban program.
 Quarterly Business Reviews
(QBR): EGV holds a regular
QBR. This has provided a forum to
discuss previous, current, and future
challenges, successes, as well as
new ideas. Federal Signal now
wants this to become the template
for all their top suppliers.
 Design for Manufacturability/
Testability (DFM/DFT): EGV has
provided DFM/DFT recommenda-
tions both as a respond to customer
engineering requests and proactive-
ly on new product.
 Goals: The customer has set several
stocking level performance goals
that EGV was able to achieve and
exceed.
The end result of this partnership ap-
proach is a well-managed program that
achieves customer goals in spite of a
high mix of products and demand varia-
bility.
ity as Director of Operations. He previ-
ously served as Production Manager at
KeyTronic EMS. He was earlier associat-
ed with ACDI, Lighting Science and Jabil
in a variety of plant, operations and
production management positions.
“EGV is growing and we felt the position
we’ve previously classified as manufac-
turing manager needed to be expanded
to encompass the activities of EGV as a
whole. Dereck brings 15 years of opera-
tions and production management expe-
rience that is specifically related to elec-
tronics contract manufacturing. He has a
track record of implementing programs
that improve both performance and
efficiency. In short, I see him as someone
who will help us add capabilities and
processes important to a diversifying
customer base, while helping us become
a leaner more efficient organization,”
said Jim Barnes, EGV’s Vice President of
Operations.
Dereck has extensive experience in 5S
and Lean manufacturing philosophy and
has pursued studies toward a degree in
Electronic Engineering.

globally to provide company-wide visi-
bility into inventory levels and materials
status. Data from Tango is also linked
to the ERP system through iScore, but
not available yet externally through
Score. Customers can access Score
24/7 via the internet for project status
visibility and program management
uses iScore to stay abreast of key pro-
ject metrics. iScore is also used internal-
ly to perform “what if” analyses when
demand trends are changing or an en-
gineering change order (ECO) needs to
be implemented. This has reduced the
time to evaluate cost impacts and avail-
able inventory from days to less than
24 hours.
The results speak for themselves. The
facility has had zero rejected shipments
since its inception in 2005. On-time de-
livery is 100 percent and there have
been zero late shipments since 2005.
The bar is set high because rejected
product not only creates potential in-
ventory shortages it the customer. It also
represents wasted logistics cost and
wasted time expended in transit and
repair. The facility’s inventory turns are
averaging slightly over 7 per year.
which automates data transfer and crea-
tion of manufacturing documentation.
Design for manufacturability (DFM) anal-
ysis is performed at the start of every
project using Valor software tools. The
documentation review process also uses a
Valor parts library (VPL) to verify the
footprint of all components specified in
the BOM against the land patterns used
in the layout. This helps eliminate both the
opportunity for defects caused by manu-
facturability issues plus eliminates the non
-value added time that can be spent
reprogramming machines or re-spinning
the printed circuit board layout if compo-
nent packaging specified in BOM doesn’t
match the land patterns used in the lay-
out.
Test and inspection strategy includes au-
tomated optical inspection and electrical
and functional testing. Functional test sys-
tems include a machine vision test that
verifies products with LED control panels
have adequate light levels and colors. In
some cases, test data is provided real-
time to the customer.
The newest software addition is an inter-
nally-developed Manufacturing Execution
System (MES) software called Tango that
is used to integrate shop floor control,
quality data collection and traceability
activities. All material is bar coded at
incoming inspection and kitting priorities
are set based on demand trends. Prod-
ucts are tracked through all production
processes associated with that work or-
der. Placement and insertion equipment
self-checks any feeders based on the
work order. If a production process set is
missed, operators cannot scan the bar-
code until the missing step is completed.
Additionally, it tracks the actual opera-
tors associated with each production step,
the revision level of any software loaded
(Continued from page 1)
in the unit and the number of units complet-
ed.
At the end of the process a Customer Advo-
cacy Audit (CAA) is performed via a sample
plan and inspection strategy designed to
ensure a 99.9 percent confidence level that
no defects are present. If the sample fails
inspection, the entire shipment is inspected.
While there is a cost associated with both
sampling and any required inspections, it is
far less than the cost incurred if the shipment
was rejected at the customer.
From a defect prevention standpoint, the
lockout mechanism makes it impossible to
skip production steps or load incorrect com-
ponents into placement equipment. From a
traceability standpoint, the system maintains
a device history record which includes com-
ponents used, production processes complet-
ed, operators associated with assembly ac-
tivities and test results. This level of data
supports quick resolution of any quality is-
sues that could potentially develop.
The facility also uses SigmaTron’s proprie-
tary “iScore” system. Through this suite of
tools, the Vietnam facility and the IPO have
visibility into forecasted demand, actual
demand, inventory in each facility and inven-
tory on order. Materials systems are linked
