New Products - 1C63

  1. 1. Silicone 1C63 • A dual cure silicone material specifically developed for electrical insulation applications • UL recognized, one part material, designed for manual and automated dispensing systems • Fast processing and eliminates shadow area concerns with secondary moisture cure WWW.HUMISEAL.COM
  2. 2. Silicone 1C63 • Designed to allow thick coating applications of up to 250mils (6.35mm) • Engineered to cure to a clear transparent finish for easy inspection following processing WWW.HUMISEAL.COM
  3. 3. Performance 1C63 • • Viscosity: 3500 +/- 1500 cps Specific gravity: 8.42 lbs./gal (1.04) • Cure conditions: UV Irradiation = 1-5 J/cm2 • Secondary Cure: 24hrs@RT or 20 min @76oC • Elongation: 100 % • Tensile : 100 psi • CTE: 3 x 10-4/oC • Shore Hardness: 15 A • Volume resistivity: 7.97 x 1014 ohms.cm • Flammability, per UL94: V1 • TI 105oC WWW.HUMISEAL.COM
  4. 4. Processing 1C63 Application • 1C63 viscosity is 3500 +/- 1500 cps • Applies easily with standard equipment, dipping, or brush. WWW.HUMISEAL.COM
  5. 5. Processing 1C63 Cure • 1C63 uses UV H bulb to cure. Depending on thickness, 1-5 J/cm2 is needed. • 1C63 will not exotherm during cure hence provides protection of any sensitive components • Any shadow areas will cure at room temperature with ambient moisture WWW.HUMISEAL.COM
  6. 6. Features Benefits Feature Benefit One part system Easy of Use VOC Free No need for abatement equipment Reduced running cost versus conventional SB systems Dual Cure UV and Moisture cure Systems Allow for rapid processing and automation Reduced WIP due to ability to ET post cure Designed for complex circuit designs UL746E for indoor and outdoor applications Broad device appeal Does not produce corrosive cure by-products Compatible with sensitive metals on the board Better rounds out the available product Possesses application diversity offering for users through high temperature tolerance Compatible with manual and automated Easy to Implement dispensing systems Fluoresces under UV light Ease of Optical Inspection WWW.HUMISEAL.COM
  7. 7. Conformal Coating How To Select? Applicable Standards & Specifications – US MIL-I-46058C – IPC-CC-830B – UL - Underwriters Labs 746E Electrical Properties – Insulation resistance, dielectric constant Thermal Properties – Operating temperature range, thermal expansion (CTE) WWW.HUMISEAL.COM
  8. 8. Conformal Coating Conformal Coating is a Simple Process 1. Clean 2. Masking 3. Coating Application 4. Dry / Cure 5. Remove MaskingTroubleshooting • But if product is not processed correctly… WWW.HUMISEAL.COM
  9. 9. Conformal Coating • Poor surface cleanliness is most common cause of coating problems – Adhesion loss – Electrical failures – Coating voids • IPC specifications recommend ionic cleanliness level of < 1.5 g/cm2 NaCl equivalenceTroubleshooting Surface Cleanliness WWW.HUMISEAL.COM
  10. 10. Conformal Coating • Need to keep within recommended ranges • Too Thick – Incomplete drying / solvent entrapment – Bubbles – Longer cure times – Shrinking or cracking – Decreased coating properties • Too ThinTroubleshooting – Inadequate Protection! Coating Thickness WWW.HUMISEAL.COM
