Company Profile
Established in 1957 in London, England, Strip Tinning remains an
independent UK-based company at the leading edge of electrical
connector manufacture for materials for the automotive front-heated
windshield market, where we are the supplier of choice.
The addition of new state-of-the-art production equipment in recent
years, including a flat-wire rolling mill, several flux-free high speed
tinning lines and sophisticated coil re-winders, ensures that our
electrical connector materials are produced to close manufacturing
tolerances with a high quality finish. In addition, Strip Tinning is the
only manufacturer in our field certified to international quality
standards:
• ISO 14001,
• ISO 9001,
• OHSAS 18001,
• ISO TS16949.
Strip Tinning Ltd is a BSI TS16949:2009, ISO14001, OHSAS18001 accredited company and compliant with VDA 6.3
Strategically situated with manufacturing in Birmingham, England, and
with sales offices in Birmingham, England and Shanghai, China, Strip
Tinning is well-placed to serve markets in Europe and beyond. Over 95%
of our products are for the overseas markets, so we have in-depth
knowledge of arranging shipments to all main areas worldwide.
We have developed partnerships with our key customers, working
together to continuously improve our products and to keep at the
forefront of these ever-changing markets. We hope that we can be of
service to you!
Automotive Busbar
(GB patent application number GB1400410.5, worldwide rights reserved)
The busbar is always based around an ultra-thin, very soft copper with a
solder coating. The thin property of the foil allows it to be applied
within the two layers of glass (actually directly onto the PVB) without
creating any significant dimensional increase that can leave air gaps in
the screen. The soft property allows the busbar to be easily shaped
when it is applied around the commonly curved glass perimeter.
Strip Tinning manufactures many busbar variants including Solder
Busbar and Adhesive Busbar, and has pioneered the development of
Pb-Free and Pb-low busbars in partnership with the key global glass
producers.
The solder coating provides two benefits – firstly, a robust soldering
process occurs within the tungsten wire application. Secondly, the
solder provides excellent corrosion resistance for the underlying copper.
This is similar to the solder busbar but has an adhesive side with a liner
for ease of application.
Many customers select a normal adhesive busbar as the base busbar
(or busbar 1) in the busbar sandwich. Here, the adhesive side is applied
to the PVB to locate the busbar in place. Some customers will then use
solder busbar as the top busbar (or busbar 2) in the busbar sandwich.
Others may select a conductive adhesive busbar as the top busbar.
Here the conductive adhesive side is placed directly onto the wire.

FFC Connectors
(GB patent application number GB1400411.3, worldwide rights reserved)
The connector components are:
A base of tinned copper with dimensions capable of carrying the
required operating current without exceeding recommended maximum
temperatures (as specified by customer).
A black polyimide insulating film to prevent corrosion
An adhesive patch with two purposes – to act as a water barrier and
prevent moisture ingress into the laminate between the connector and
glass surface; and to secure the connector to glass surface.
The process steps used by Strip Tinning to make these connectors are:
•
•
•
•
•
Lamination of insulating film onto tinned copper, and application of
the adhesive patch
Welding or soldering of a terminal or cable to an end of the tinned
copper
Overmoulding of the welded or solder joint
Attaching a terminal, seal and housing to the cable as requested by
the customer.
Application of a solder deposit to the connector to allow ease of
soldering to busbar.
Tungsten Wire
Preformed Corners
This is an essential material for manufacture of Electrically Wired
Heated Windscreens. It is used as the near-invisible heating element
within the glass viewing area, and is the obvious choice due to excellent
tensile strength (even at very high temperatures) and good corrosion
resistance.
Type of Tungsten Wire: Black (W) Type – (Black with graphite coating)
Diameter: According to customer request – Range of sizes available.
Ohms tolerance: +/- 3% throughout the whole coil of black tungsten
wire.
Density: 19.35g/cm3

Preformed Corners, also called Die-cuts, are used within laminated
glass on the corners of the screen. Usually the busbar can be folded in
order to meet the contour of the screen, but as they are becoming
more curved this folding can create a lot of stress on the glass leading
to cracking and increased failures. The preform can be shaped to meet
the contours of the screen, and therefore there is no requirement for
doubling the busbar thickness (by folding). This will result in increased
output and less scrap.
Preforms generally range from 50 up to 100 microns thickness
dependant on customer requirements and are available in various
coatings.

Backlite Connectors
Backlites are becoming an ever increasing product within the
automotive glazing market, STL produces several variations of backlite
connectors;
•
T-pieces are used on backlites and side windows as heating
connectors. T-pieces can be produced in any design or shape as
requested by the customer and can be produced from Plain Copper,
Tinned Copper or Silver plated. Some designs can also include heatshrink tubing and other materials for added insulation, as well as
solder preforms applied to the footings of the solder bridge.
•
Antennae Connectors used for Radio, TV and GPRS signals, which
allow for signals to be transmitted from the backlite to the
electronics of the vehicle. We partner with leading ferrite coil and
capacitor manufacturers in order to produce connectors which are
able to target the frequency required by the customer in order to
reduce interference.
Quality and Controls
Our state of the art rolling mills, slitters, treatment and coating lines
guarantee our exceptional standards. We are supported by TS16949
management system certification, and the very highest levels of
environmental management & occupational health and safety through
our ISO14001 and OHSAS18001 accreditations.
