Parylene-Coated Solder Powder (Parylene@Solder)
Parylene@Solder powder carries a vapor-deposited, pinhole-free conformal coating that is thin enough to melt away cleanly during reflow while protecting the solder particles from oxidation and moisture during storage.

Parylene-Coated Solder Powder — Grades & Specifications
Parylene-Coated Solder Powder (Parylene@Solder) powder is supplied across a range of grades, particle sizes and coating ratios. The options below are typical; specify your target values in the request form and we will confirm availability, lead time and pricing.
| Material | Parylene-Coated Solder Powder (Parylene@Solder) |
|---|---|
| Category | Polymer-Coated Powder |
| Core material | Solder alloy (e.g. Sn63/Pb37 eutectic or lead-free SAC alloys) |
| Coating / shell material | Parylene (poly-para-xylylene) conformal coating (CAS 1633-22-3) |
| Coating content | Extremely thin — typically 0.001-0.2 wt%, with 0.005-0.025 wt% most commonly used |
| Particle size | Graded by industry Type per J-STD-005: Type 3 approximately 25-45 um, Type 4 approximately 20-38 um, Type 5 approximately 15-25 um, Type 6 approximately 5-15 um |
| Morphology | Spherical (preferred for paste printability); amorphous/irregular shapes also usable |
| Appearance | Bright metallic gray spherical powder, visually near-identical to uncoated solder powder since the coating is sub-micron |
| Shelf Life | Parylene-coated solder pastes demonstrate shelf life commonly exceeding 6 months to over a year with viscosity increase typically held under 30% over that period, versus uncoated solder powder which oxidizes and reacts with paste flux far faster |
| Typical applications | SMT Solder Paste for Stencil Printing, Fine-Pitch BGA/CSP Reflow Assembly, No-Clean Solder Paste Formulations, Long-Distance / Export Electronics Manufacturing |
Applications by Industry
SMT Solder Paste for Stencil PrintingExtends usable shelf life of paste jars and cartridges before oxidation degrades print quality.
Fine-Pitch BGA/CSP Reflow AssemblyThin oxide-free coating supports consistent wetting on small-pad, fine-pitch components.
No-Clean Solder Paste FormulationsCoating reduces flux-metal side reactions, supporting low-residue no-clean chemistry stability.
Long-Distance / Export Electronics ManufacturingExtended shelf-stable paste tolerates longer shipping and storage before use.
Automated Dispensing & Jet-Printing PasteStable viscosity over time keeps dispense volume consistent in automated lines.
Rework & Repair Solder PasteLow-turnover inventory benefits from oxidation resistance during intermittent, infrequent use.
