1. The Conformal Coating Journey Marie Kaing Key Account Manager

2. Summary  History of Conformal Coating  Current global market share  Factors influencing industry trends  Test specification evolution

3. History of Conformal Coating

4.  50 years- Parylene (Vacuum deposition)  Protection with thin layer (25-75microns)  Technology reserved for high reliability military and aerospace  Only the most expensive PCB coated  Material + process = Too high cost

5. History of Conformal Coating  Electronics becoming more fragile due to:  Circuit size reduction  Higher component densities  Increased features & capabilities  Cheaper circuit costs,  Constant growing need for more protection  Expanded use of Conformal Coatings  Developments of new technologies, new needs for new markets

6. Reliability  Reliability is becoming a “must have” for today’s electronic devices  Demands are filtering down to everyday consumer goods  Conformal Coating enable to:  Reduce premature failure  Provide longer warranty  Enhance perception of quality  What is the cost argument?

7. Reliability cost  Electronic for a car radio  Apply a Conformal Coating:  PCB size: 100mmX100mm  Material volume/board: 100mmX100mmX0.050mm = 0.5cm3  Material cost/board= €0.06  Labour &equip/board = €0.02  Total approx coating cost = €0.10/board

8. Reliability cost  Without a conformal coating  1 field failure = €130 to replace the radio (€60 radio + €70 labour)  Coating costs equate to 1 field failure in 1300 boards  Coating costs equate to 0.1% of radio cost

19. Test Specifications Evolution

20. Test specifications origins  Standards and specifications provide benchmarks to the industry to maintain a certain level of quality on CC  1960: MIL-I-46058C  1 st conformal coating standard  1984: IPC-CC-830  commercial version of Mil spec  Relatively easy to pass  All conformal coatings pass MIL and IPC spec.

21. Test specifications evolution  Changes in specifications are being driven by:  Increasing use of electronics in unusual environments.  Generate industry competitiveness  For example:  Greater Tshock  More fuels/vapors/chemicals exposure  Corrosive atmospheres  Higher temperature excursions

22. Example of harsher test conditions  MIR test: 164h  500h  1000h  1500h  T-shock: 100cycles  500cycles  1000cycles  1649cycles  Visual inspection done under stronger magnification ie 40X instead of 10X  Total water immersion test

23. IPC test IPC-CC-830 specification

24. Customer test Customer specification IPC-CC-830 specification

25. Individual test sequence Temperature cycle Thermal shock Humidity cycle Salt spray test Visual inspection Different boards go through each test sequence

26. Cumulative test sequence Same board goes through the entire test sequence Temperature cycle Thermal shock Humidity cycle Salt spray test MIR test Visual inspection Damp heat

27. Example of new test spec  New CL12 test for Peugeot and Volvo:  Cumulative test on PCB:  Thermal shock: 500 cycles (-40C+125C)  Spray test with drops of acid solution  85/85 for 1000 hours under 50V  Today there is no conformal coating in the market capable of passing this new test specification
