2 Content PME Precision Mesh Electronics Applications Challenge Requirements Solutions PCF Pre Coated fabric Improvement of industrial screen printing stencil fabrication

3 Applications Decorative and functional printing

4 Challenge Ready to use after short process time High tensions possible Minimal loss of tension Consistent dimensional stability Long print runs Long stencil lifetime Cost saving Reduction of waste

5 Requirements How to produce a state of the art screen Screens with high dimensional stability High sustainable threads and progressive weaving process Balanced elongation Controlled stretching process and accurate tension levels Measurement devices = A perfect screen

6 Screens with high dimensional stability Requirements Frame dimension, profile and material Precision mesh for high-end industrial screen printing Perfect stretched

7 High sustainable threads and progressive weaving process

8 Balanced elongation in warp and weft

9 Controlled stretching process and accurate tension levels

10 Measurement devices SEFAR Tensocheck 100 with control plate and interface SEFAR Humicheck Emulsion dry Emulsion partially dry Emulsion wet Thickness & roughness measurement device

11 Solution SEFAR PME (Presicion Mesh Electronics) SEFAR PME has been specially developed for the tough demands of industry. Woven with a special, high module polyester yarn, guaranteeing a balance in warp and weft. Designed for short exposure times.

12 SEFAR PME Low tension loss

13 SEFAR PME Dimension stability Mesh: PME Y Frame: 1x1m Tension: 30N/cm Prints: Deviation: max. 116µm

14 SEFAR PME Product range

15 SEFAR PME Benefits

16 Conclusion SEFAR PME - is the precision screen printing mesh on the market to consistently meet the industry s demand for top class printing.

17 Improvement of industrial screen printing & stencil fabrication

18 Stencil making Coating with direct emulsion 1. Stretching Applying capillary film 1. Stretching 2. Degreasing 3. Drying 2. Degreasing 3. Wetting agent 4. Coating 5. Drying 4. Capillary film 5. Drying 6. Exposing Developing Drying 6. Exposing Developing Drying

19 Reduction from 6 to 2 process steps Coating with direct emulsion 1. Stretching Applying capillary film 1. Stretching 2. Degreasing 3. Drying 2. Degreasing 3. Wetting agent 4. Coating 5. Drying 4. Capillary film 5. Drying 6. Exposing Developing Drying 6. Exposing Developing Drying

20 Types of coating SEFAR PCF FC Direct emulsion Capillary film Capillary film combined with direct emulsion

21 SEFAR PCF FC Best reproducibility Uniform EOM + Uniform surface roughness + Uniform mesh thickness = Reproducible printing results in its entirety

22 SEFAR PCF FC: Best Resolution SEFAR PCF FC Y Half-tone/ 55 µm Line

23 Comparison printing quality Direct emulsion Capillay film SEFAR PCF FC

24 SEFAR PCF FC = Cycle-/Labour Time Reduction Example: label printing Conventional (sec) 1 screen Conventional (sec) 2 screens PCF FC (sec) 1 screen PCF FC (sec) 2 screens Cycle time Labour time Cycle time Labour time Cycle time Labour time Cycle time Labour time Intake control Screen degreasing Screen drying Screen coating Screen drying Screen additional coatin Screen drying Screen to stock Total time in sec Total time in min

25 Added values with SEFAR PCF FC Reproducible and high quality screen prints Low EOM and low surface roughness with minor effort High reproducibility and process standardization Reduction from 6 to 2 process steps in stencil production Drastically reduction of consumables like photo emulsion or capillary films, degreasing-, wetting agents, ghost image removers - Better labour protection - environmental friendlyness - Reduction of waste management costs Little space requirements for stencil production

26 Added Values with SEFAR PCF FC High quality screen prints require stencils with low EOMs and Rzvalues Conventionally done low EOMs and Rz-values are very labour intensive not with PCF FC The reproducibility is far above what screen printers usually are used to know. Speeds up the stencil production, screen printer bottle neck No. 1

27 Vision PCF FC Expose and Go PCF FC sets the standard of stencil making for industrial applications Leanest screen production workflow Safe and easy to use Unbeaten printing quality
