Sn62Pb36Ag02 Solder Balls (Silver-Bearing Tin-Lead)

Sn62Pb36Ag02 solder balls are a silver-bearing eutectic tin-lead alloy, melting at 179 °C, used for BGA and CSP ball attach on silver-metallized terminations and for legacy and repair assemblies. EasySpheres supplies Sn62Pb36Ag02 solder spheres in multiple diameters, in conformance with IPC J-STD-006, with a Certificate of Conformance on every order.

Sn62Pb36Ag02 Solder Sphere Specifications

  • Alloy: Sn62Pb36Ag02 (62% tin, 36% lead, 2% silver), eutectic tin-lead-silver
  • Applications: BGA and CSP ball attach, silver-metallized terminations, BGA rework, legacy assemblies
  • Melting point: 179 °C (eutectic)
  • 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%; inspection illuminance greater than 270 lux.
  • Quality: Alloy purity in conformance with IPC J-STD-006 (composition per J-STD-006C); Certificate of Conformance ships with every order.
  • Compliance: Leaded (tin-lead) alloy; not RoHS-compliant as supplied. Supply is not prohibited; REACH Article 33 disclosure available. Confirm that your application or exemption permits tin-lead solder before ordering.
  • Packaging: Medical-grade, ESD-safe containers designed to resist the surface darkening caused by transit tumbling, reducing machine-vision faults in automated ball placement systems; QR-coded for lot conformance traceability and shipping accuracy.
  • 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

What is the melting point of Sn62Pb36Ag02?

179 °C. The 2% silver addition lowers the eutectic slightly below Sn63Pb37 (183 °C).

Why choose Sn62Pb36Ag02 over Sn63Pb37?

The silver content reduces silver leaching from silver-metallized terminations and can improve joint strength and fatigue resistance. Choose it where the assembly specification calls for a silver-bearing tin-lead solder; otherwise Sn63Pb37 is the standard choice.

Is Sn62Pb36Ag02 RoHS-compliant?

No. Sn62Pb36Ag02 is a leaded alloy and is not RoHS-compliant as supplied. Its supply is not prohibited, and EasySpheres provides a REACH Article 33 disclosure. Confirm that your application or exemption permits tin-lead solder before ordering.

What should I check when selecting Sn62Pb36Ag02 sphere size?

Take the diameter from the BGA or CSP package documentation or approved rework specification and confirm compatibility with the pad geometry and placement stencil. EasySpheres stocks diameters across the 0.050 to 0.889 mm range.

How is Sn62Pb36Ag02 product conformance documented?

Every order ships with a Certificate of Conformance covering composition (per IPC J-STD-006C), solidus and liquidus, size distribution, and sphericity, and the packaging is QR-coded for lot traceability.

Why Buy Solder Spheres from EasySpheres

Ordering and Support FAQs

Can I order Sn62Pb36Ag02 solder spheres in small quantities?

Yes. EasySpheres supplies Sn62Pb36Ag02 solder spheres with a minimum order of 10,000 spheres and scales to production volumes. Request a quote for larger requirements.

How quickly do Sn62Pb36Ag02 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 Sn62Pb36Ag02 solder spheres?

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 Sn62Pb36Ag02 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.
