SOLUTIONS FOR THE AUTOMOTIVE ELECTRONICS INDUSTRY

One Resource. Hundreds of Products. Unlimited Solutions.

3M Electronics Markets Materials Division brings exceptional technical and design

capabilities to the creation of materials solutions for highly demanding and

dynamic automotive industry.

These solutions involve adhesives, tapes, marking systems, abrasives,

specialty chemicals and coatings. They serve a broad range of

applications that result in improved manufacturing processes,

higher quality electronics components, enhanced productivity,

and reduced environmental impact. To help assure these

successful outcomes, engineers at a global network of

3M Application Development Centers design solutions for our

clients. Comprehensive expertise makes 3M a start-to-finish

resource for meeting a vast array of challenges in the electronics

industry.

• Thermal Management

• EMI/RFI Shielding

• Product Identification

• Cleaning

• Lapping, Polishing, and Planarization

• Product Security and Protection

• Packaging and Shipping

Higher integration densities of electronic components

and the resulting greater waste heat generation

require appropriate heat management in automotive

electronics, the new core competency of car manu-

facturers. A further consideration to accommodate as

many components as possible in ever-decreasing

spaces often makes soldering impossible. 3M can help

you to solve these new requirements efficiently and

economically.

Cleaning

3M™ Novec™ Engineered Fluids are used in a wide variety of

electronics cleaning applications, including vapor degreasing,

immersion, aerosol spray cleaning and hand wiping. Cleaning

systems incorporating Novec fluids help you address environmental

and worker safety concerns-while offering excellent cleaning performance.

• Extremely low surface tension and viscosity to penetrate under surface mount devices.

• Non-corrosive and compatible with sensitive substrates

• Can be used in existing vapor degreasing equipment

• Reduced emissive and drag-out losses

• "Cost-in-use" comparable to other solvent systems

• Fast drying

• Selective solvency

• Low water solubility

Fluorochemical Coatings

3M™ Novec™ Electronic Coatings provide protection from moisture, soils,

humidity and other environmental contaminants for many electronic

components. They are fluorochemical acrylate polymers that are surface

modifiers and provide very thin coatings for anti-migration, anti-stiction and anti-corrosion. Used on printed

circuit boards, MR heads in disk drives, and sensitive electronic components, they can offer:

• Improved reliability

• Extended life of the product

• Reduced process time

• Excellent environmental and safety properties

3M™ Novec™ ECG-1700 fluid has been formulated to replace 3M™ Flurorad™ FC-722, FC-732, FC-724

and FC-725™ fluids, and to meet the purity solvent demands of the electronics industry.

Development and technical support

3M’s goal is to use existing solutions optimally and develop new solutions for new customer requirements.

To achieve this, 400 chemists and engineers from 9 countries are hard at work at our European Development

Laboratory in Neuss, Germany.

In this ultra-modern laboratory,state-of-the-art adhesive and markingsystems products are developed forthe Automotive Industry.

Our customers can find out aboutthem at meetings and workshops onthe spot.

Our local technical service engineers,based in Customer Technical Centresacross Europe, are available to supportyou in the practical implementationof a 3M solution for your individualapplication.

Regulations and Recycling

Regulations, specifications and standards play a crucial role in supplying car manufacturers and the whole

component supply industry. The self-imposed obligation by car manufacturers to re-use 95 per cent of the mass of

a vehicle, to be implemented by 2015, is particularly important.

For this reason, an internationalmaterials database system (IMDS)has been set up.

This database contains informationabout the materials used to manu-facture the individual componentssupplied.

3M is particularly keen on this subject.Products supplied to the automotiveindustry by 3M are gradually incor-porated into the IMDS system, andchecked for reusability and recyclability.

This provides efficient support of andinformation on product environmetalsustainability to our customers.
