Teknek Approach

• Partnership Approach

– Develop specific solutions

• We lead, others follow

– Polymers

» After 20 years competitors cannot match our silicone

products

» Nanocleen is still unique

• Machines

– New ideas – fast development

– Competitors – poor copies, no innovation

Global Expertise

• Internal R&D

– We know our stuff

• Rollers and Adhesive

– Dr June Calliston, Polymer Expert

– Sheila Hamilton, Engineer and 30 years roller experience

– Steve Mitchell, Managing Director, Physicist and Chemist

• External collaboration

– Teknek works with the best Universities and

companies to develop the science

Scale

• Big is sometimes Beautiful?!

– To supply good rollers you have to MAKE

many not BUY many

• In 2013 will MAKE over 10,000 rollers

– To be able to produce reliable adhesive you

have to Specify the paper, the adhesive, the

production process etc. etc.

• In 2013 we will make around 1.2 million sq. metres

Trust in us – Teknek Brand

• All rollers are made to International

Standard– ISO 6123 Rubber or Plastics covered rollers -Parts 1,2 & 3

– Rollers used above 200 mtrs per min are balanced to ISO 1940-

1:2003 G6.3

• Large rollers now available at G2.5

• We test, everything• Rollers for pick up, leach, straightness, TIR etc.

• Adhesive for pick up, sheer, peel, etc.

– Tested to FTM 1,8,9 &12 (International Standards)

• And we test all competitors the same way

We speak – others Listen

• Teknek is invited to speak at International

conferences on

– Cleaning advanced electronics

– Coating & converting

• Why?

– We have information that scientists and

engineers need

– What we do advances the industry

What are we saying?

• Cleaning is difficult but we understand it

– The Science of Cleaning

• Contact Cleaning Conceptual Framework

• Model developed by Teknek & University of Sheffield

– Key Scientific Outcomes

» Cleaning efficiency≠ Shore Hardness

» Contact pressure ≠ Cleaning efficiency

» Processing ≠ Cleaning

» More rollers ≠ More Cleaning

What are we saying 2

• Not all cleaning rollers are the same

• Smooth tacky rollers don’t work best

• Our roughest rollers work best – why?

• Using Advanced Scientific Methods* we have

measured roller surface, and the forces to remove

particle from customer sample and roller.

– This allows us to modify roller surfaces and create

unique rollers.

* (Atomic force microscopy (AFM) or scanning force microscopy (SFM)

Innovation 1

• Silicone Free Cleaning Engine

– Silicone free cleaning rollers

– Silicone free adhesive

– Silicone free confirmed by

– FTIR, (Fourier Transform Infra-Red

Spectroscopy)

– Edx (Energy-dispersive X-ray spectroscopy)

– RGA (residual gas analysis)

Innovation 2

• Nanocleen

1.Silicone free

2.Static dissipating NO conductive particles – clever

polymers which are conductive.

3.Surface Energy - contact angle

(Measurements on PET)

• Uncleaned contact angle 71.57, SD +/- 1.49

• Cleaned with Nanocleen 71.80, SD +/- I.46

Innovation 3

• UTF Elastomer

– Surface modified

– High cleaning capacity

– Can clean sheets of film as thin as 15 microns

(15µm)

– Can clean thin copper foil without wrinkles

Innovation 4

• Vacuum Compatibility

– Can be used in high vacuum environments

– No outgassing from elastomer or adhesive

– Silicone free system

– No reduction in cleaning performance

– No detriment to vacuum system
