Adhesive

A reverse wound adhesive roll that runs in contact with the elastomer roller retaining the contamination that has been removed by the cleaning roller.

Adhesive Transfer

The transfer of adhesive from Adhesive roll to Cleaning roller and then to the customer material. Such transfer can damage the process or product.  

ANSI/ESD s20.20 2014

International standard for Development of an Electrostatic Discharge Control Program.  Learn more at www.esda.org/standards/ 

Anti-Static

An antistatic material is one which helps  to reduce or eliminate the build-up of static electricity 

AOI

Automatic Optical Inspection 

AREP

Adhesive Roll Eco Paper

AREF

Adhesive Roll Eco Film 

ARLS

Adhesive Roll Low Static 

CCR

This is a PolymagTek term meaning Contact Cleaning roller

Chemical Transfer

Sometimes refered to as 'Leaching' or 'Chemical Leaking'. In this context, it applies to chemicals or other substances that migrate from cleaning rollers or adhesive rolls. This is an important measurement process as the 'chemicals' migrate to the customer materials  

Coating / laminating

Coating is the application of a liquid substance at variable thicknesses to a moving web. The methods of application can be varied.  

Contact cleaning

Where an elastomer roller touches the substrate that is being cleaned and transfers dry unattached particles to a reverse-wound adhesive roll. 

Contamination control

The process to ensure product and environment is kept free from contamination.

Converting

The converting industry takes continuous rolls of thin, flat materials — known as webs — threads them through processing machines (such as printing presses, laminating, coating and slitting machines) and converts or changes the web of material into an intermediate form or final product. 

DCR

Dust Collecting Roller 

DCR pad

Dust Cleaning Roller adhesive pad. Used to clean the DCR hand roller

Elastomer roller

The cleaning roller that touches the substrate

FINAT

Self Adhesive Federation with Regulated test standards. Learn more at www.finat.com/knowledge/test-methods
 

FPD

Flat Panel Display. Devices to enable people to see content. Includes TV, Computers, Tablets, Smartphones etc.

FTIR

Fourier transform infrared spectroscopy is a technique which is used to obtain an infrared spectrum of absorption or emission of a solid, liquid or gas. An FTIR spectrometer simultaneously collects high spectral resolution data over a wide spectral range. Used widely by Teknek. 

Hand roller DCR

A hand-held roller that is used to clean substrates. The contamination is then transferred to an adhesive pad. 

Industry 4.0

Automation and data exchange in manufacturing technologies – the Internet of things. 

Nanocleen™

Teknek elastomer roller. Removes Nano particles (tested using 25/45 nm silver particles)

Nip Pressure

The pressure as measured at the point that 2 rollers meet. Nip Pressure is typically measured in units of N/cm2

PCB

Printed Circuit Board 

PCBA

Printed Circuit Board Assembly

PPU

Particle Pick Up. An analytical test method developed by Teknek to measure the cleaning effectiveness of rollers and adhesives. The test uses three different types of particles to assess effectiveness. PPU is expressed in g/m2 

Reel to Reel machine

A machine that processes a continuous web 

Sheet cleaning

Cleaning of individual sheets of materials.  

Shore Hardness

A measure of Hardness. Hardness may be defined as a material's resistance to permanent indentation. The durometer scale was defined by Albert Ferdinand Shore. 

SMT

Surface Mount Technology 

SPI

Solder Paste Inspection  

Surface Roughness

Surface roughness often shortened to roughness, is a component of surface texture.  

Taber Test

Taber Abraser is a precision built instrument to perform accelerated wear testing of many materials including elastomers. The process to measure wear in items like cleaning rollers is defined in the ASTM D3489 standard. 

Tack 

Tack is the property of adhesives that allows the immediate formation of a bond on contact with another surface - in other words, it is a definition of the 'stickiness' of the adhesive.

 Web

A web refers to a continuous sheet of relatively flexible material, like paper or film. 

Web cleaning

Cleaning a reel of material. The motion of the web drives the rollers and adhesives.  

Yield

A measure of good units with no rework or scrap produced by an individual process.

Yield improvement

Improving the first time pass of usable product that is being manufactured. Results in a direct improvement to the product quality. 

Zero Defects

Zero Defects is a management tool aimed at the reduction of defects through prevention.
