WIMA Quality and Environmental Philosophy
ISO 9001:2008 Certification
ISO 9001:2008 is an international basic
standard of quality assurance systems for
all branches of industry. The approval
according to ISO 9001:2008 of our
factories by the VDE inspectorate certifies
that organisation, equipment and moni-
toring of quality assurance in our factories
correspond to internationally recognized
standards.
WIMA Environmental Policy
All WIMA capacitors, irrespective of
whether through-hole devices or SMD,
are made of environmentally friendly
materials. Neither during manufacture
nor in the product itself any toxic
substances are used, e.g.
–
–
–
–
–
Lead
PCB
CFC
Hydrocarbon chloride
Chromium 6+
–
–
–
–
–
PBB/PBDE
Arsenic
Cadmium
Mercury
etc.
RoHS Compliance
According to the RoHS Directive 2011/65/EU
certain hazardous substances like e.g. lead,
cadmium, mercury must not be used any
longer in electronic equipment as of July 1st,
2006. For the sake of the environment WIMA
has refraind from using such substances since
years already.
WIMA WPCS
The WIMA Process Control System (WPCS)
is a quality surveillance and optimization
system developed by WIMA. WPCS is a
major part of the quality-oriented WIMA
production. Points of application of WPCS
during production process:
”
”
”
”
”
”
”
incoming material inspection
metallization
film inspection
schoopage
pre-healing
pin attachment
cast resin preparation/
encapsulation
”
100% final inspection
”
AQL check
We merely use pure, recyclable materials
for packing our components, such as:
”
”
”
”
carton
cardboard
adhesive tape made of paper
polystyrene
WIMA Kondensatoren sind bleifrei
konform RoHS 2011/65/EU
WIMA capacitors are lead free
in accordance with RoHS 2011/65/EU
Tape for lead-free WIMA capacitors
We almost completely refrain from using
packing materials such as:
”
foamed polystyrene (Styropor®)
”
adhesive tapes made of plastic
”
metal clips
DIN EN ISO 14001:2004
WIMA’s environmental management has
been established in accordance with the
guidelines of DIN EN ISO 14001:2004 to
optimize the production processes with
regard to energy and resources.
