Sn20Pb80 High-Lead Solder Balls

Sn20Pb80 solder balls are a high-lead tin-lead alloy (80% lead, 20% tin) used for semiconductor packaging, BGA rework, PCB repair, legacy assemblies, and laboratory work that specifies a high-lead solder. EasySpheres supplies precision Sn20Pb80 solder spheres in conformance with IPC J-STD-006, with a Certificate of Conformance on every order.

Sn20Pb80 Solder Sphere Specifications

  • Alloy: Sn20Pb80 (20% tin, 80% lead), high-lead tin-lead
  • Applications: Semiconductor packaging, BGA rework and reballing, PCB repair, legacy assemblies, laboratory testing
  • Stock diameters: 0.050 mm to 0.889 mm range; see the product listing for diameters and part numbers
  • Dimensional tolerance: Maximum dimensional tolerance ±4% (typical measured ±0.50% for 0.050 to 0.450 mm, ±1% for 0.500 to 0.550 mm, ±0.83% for 0.600 to 0.889 mm); sphericity deviation less than 1.5%.
  • Quality: Alloy purity in conformance with IPC J-STD-006; Certificate of Conformance ships with every order; standard quality documentation available on request.
  • Compliance: Leaded (tin-lead) alloy; not RoHS-compliant as supplied. At 80% lead it does not meet the 85% threshold of RoHS Annex III exemption 7(a); confirm that your application or another exemption permits its use. Supply is not prohibited; REACH Article 33 disclosure available.
  • Packaging: Medical-grade, ESD-safe containers designed to resist surface darkening from transit tumbling; QR-coded for lot traceability.
  • Shelf life: Two years from the date of shipment from the EasySpheres facility (product held sealed in controlled inert storage until shipped).
  • Minimum order: 10,000 spheres

EasySpheres warrants this product to be defect free, with alloy purity in compliance of IPC-JSTD-006 guidelines.

Size deviation shall not be greater than:
± 0.010% for sizes .0.004" ~ 0.018" (0.100mm~0.450mm)
± 0.015% for Sizes 0.020" ~ 0.022" (0.500mm~0.550mm)
± 0.020% for Sizes 0.024" ~ 0.035" (0.600mm~0.889mm)

Shelf life of 1 year is guaranteed by EasySpheres from date of purchase.

Frequently Asked Questions

Where can I source high-lead solder balls in small quantities?

From EasySpheres. Sn20Pb80, Sn10Pb90, and Sn05Pb95 are available from 10,000 spheres in multiple diameters. Contact EasySpheres to confirm the alloy and diameter for your application.

Where can I buy solder spheres for BGA rework and reballing?

EasySpheres supplies solder spheres for BGA rework in tin-lead, high-lead, and lead-free alloys. Choose the alloy and diameter specified for the BGA package.

Are Sn20Pb80 solder balls RoHS-compliant?

No. Sn20Pb80 is a tin-lead alloy and is not RoHS-compliant as supplied. Because it contains less than 85% lead, exemption 7(a) does not apply; confirm your intended application or exemption before ordering.

Which tin-lead solder balls are best for legacy BGA rework?

Sn63Pb37 is the standard alloy for legacy BGA rework. Sn20Pb80 and the other high-lead alloys are used where the assembly specification calls for a higher-melting tin-lead joint. Contact EasySpheres if you need help matching one.

Why are Sn20Pb80 solder balls used in semiconductor packaging?

High-lead alloys stay solid through later, lower-temperature soldering steps, which makes them suitable for first-level interconnects and certain high-temperature applications. Always verify the alloy and diameter required for your package.

Why Buy Solder Spheres from EasySpheres

Ordering and Support FAQs

Can I order Sn20Pb80 solder spheres in small quantities?

Yes. EasySpheres supplies Sn20Pb80 solder spheres with a minimum order of 10,000 spheres and scales to production volumes. Request a quote for larger requirements.

How quickly do Sn20Pb80 solder spheres ship?

Most in-stock orders placed before 2:00 PM Pacific ship the same day; other orders ship within 24 hours. EasySpheres maintains a greater-than-95% on-time delivery record.

What documentation ships with Sn20Pb80 solder spheres?

No. Sn20Pb80 is a tin-lead alloy and is not RoHS-compliant as supplied. Because it contains less than 85% lead, exemption 7(a) does not apply; confirm your intended application or exemption before ordering.A Certificate of Conformance ships with every order, covering alloy composition, solidus and liquidus, size distribution, and sphericity. The technical data sheet and SDS are available on the product page, and standard quality documentation is available on request.

What is the shelf life of Sn20Pb80 solder spheres?

The stated shelf life is two years from the date of shipment from the EasySpheres facility. Prior to shipment the product is retained in its original sealed packaging within a controlled inert storage environment designed to minimize exposure to moisture, oxygen, and contaminants.
