  4. PTH Process Overview Application and Pricing Guide

  5. Horizontal Electroless CopperPrintoganth P Plus

  6. Printoganth P Plus enables highest flexibility in production mix Printoganth P PlusFeatures & Benefits • Market Introduction in Sept. 2009 • Target Application • Any production with advanced materials where adhesion or blistering is an issue e.g. flex, rigid-flex, PTFE, BT, PI, etc. • HDI and AMSAP technology • Technical Benefits • Extremely good non-blister behavior and coverage performance • Very good reliability • Easily adjustable deposit rate 0.35 – 0.5µm / 4 min • Enhanced bath stability

  7. Printoganth P Plus is Atotech’s most capable process for HDI manufacturing Horizontal MLB and HDI ProcessesComparison CN- , JPO

  8. Horizontal DesmearUniplate P Sweller Permanganate Etch Reducer • SECURIGANTH® desmear series is the industry standard for horizontal HDI manufacturing. • Optimal desmear attack on a wide variety of base materials.

  9. Horizontal Activation & E’less CuUniplate LB Cleaning Etch Cleaning Pre Dip Neoganth 800 Activator Reducer E’less Copper

  10. Economic Activator Neoganth 800Features & Benefits • New Ionic activator system for horizontal application running at only 75ppm Pd • Activator U = 225 ppm • Enables significant savings in running costs by less consumed Pd • Fully compatible to established Atotech conditioning system • easy drop in solution • Perfect coverage on a wide range of relevant base materials • Same excellent reliability results as Activator U • Robust & easy process • Wide working window Activator 800 during Alpha site test

  11. Printoganth P series X relative strain Z Non-Blistering PerformanceTheoretical Explanation • Non-blistering performance is related to internal stress within deposited e’less Cu layer • Relevant factors for Cu deposit behavior • Stabilizer type & concentration • Stabilizer Co-deposits (e.g. Ni) • Deposition temperature • Baking after electroless Cu deposition • X-ray diffraction (XRD) measurement reveals constant tensile stress with Printoganth P Plus – a type of internal stress that is beneficial for non-blistering!

  12. Printoganth P PlusApplications FR4 Production Board Flex-Rigid Board • No Blistering due to excellent stress characteristics • Bright deposition color

  13. Printoganth P Plus fulfills all reliability requirements for high-end HDI production. ReliabilitySummary • Quick Via Pull test, 3-6 mil – all passed. • Solder Shock Test (6x 288°C, 10s floating) – No ICDs, passed.with THs and BMVs • Solder Shock Test (9x 326°C, 10s), THs & BMVs – few ICDs, ok.with THs and BMVs • IST (+150°C / RT @ 3’/ cool down within 2‘, max. 10% resistance increase) – 2000 cycles passed. • Various E-tests (daisy chains) – all passed.

  16. Process SequenceActivation & E‘less Cu Desmear Cleaning Etch Cleaning Pre Dip Neoganth V8 (60 ppm) 50 Activator Reducer E’less Copper

  17. Activation Series Neoganth LS PlusFeatures & Benefits • Ionic Activator for vertical application • Optimal coverage at low running cost (75ppm Pd) • Fine & homogeneous distribution of Pd particles • No tooling hole issues • Not corrosive • Improved robustness, no precipitations during manual replenishment • Easy handling, no premixing • 100% compatible to established conditioning concept Pre Dip Activator Reducer

  18. Activator Neoganth V8 – full power ionic activation at low cost Economic Activator EXPT Neoganth V8Features & Benefits • New ionic activator system for vertical MLB/HDI applications running at only 60 ppm Pd • Enables significant savings in running costs by less consumed Pd • Modified complexing agents • Ensures good coverage despite low palladium content • ‘Locking’ copper ions in a stable complex enhances bath lifetime • Less alkaline • Improved bath stability by reduced carbonate formation • Perfect coverage on a wide range of relevant base materials • Fully compatible to established Atotech conditioning system • Easy drop in solution • Robust & easy process • No additional NaOH dosing required by optimized replenishment concept • Wide working window

  19. Printoganth PV vs PV EComparison … Cleaning Etch Cleaning Pre Dip • Identical stabilizer system • Same bath performance • Different Cu source (CuSO4, CuCl) to be more flexible in supply chain • PV E potentially more cost-effective due to higher concentrated Cu additive Activator Reducer E’less Copper

  20. Printoganth PV (E)Features and Benefits • Versatile vertical e’less Cu process for advanced MLB/HDI applications • Superior adhesion on most materials including PI, PTFE, BT... due to optimal internal stress characteristics of the copper deposit: • No blistering • No pull away • Highly reliable process • Fulfills all standard reliability requirements such as SST, IST, TCT • No ICDs at standard conditions and only low occurrence at harsh solder shock conditions as 9x 326ºC • Low to high build deposit possible • Deposition speed 0.3 - 0.6µm in 10 min • Environmentally friendly • Tartrate based • Cyanide free
