Sn96.5Ag3.5 Solder Balls (Eutectic Tin-Silver)

Sn96.5Ag3.5 solder balls are a lead-free eutectic tin-silver alloy (no copper) with a single 221 °C melting point, used for BGA and CSP ball attach and applications that specify a binary SnAg solder. EasySpheres supplies Sn96.5Ag3.5 solder spheres in multiple diameters, in conformance with IPC J-STD-006, with a Certificate of Conformance on every order.

Sn96.5Ag3.5 Solder Sphere Specifications

  • Alloy: Sn96.5Ag3.5, eutectic tin-silver, lead-free (this alloy contains no copper and is not a SAC alloy)
  • Applications: BGA and CSP ball attach, BGA rework, assemblies specifying binary SnAg solder
  • Melting point: 221 °C (eutectic; solidus and liquidus coincide)
  • Stock diameters: 0.050 mm to 0.889 mm range; listed diameters on this page: 0.200, 0.250, 0.300, 0.350, 0.400, 0.450, 0.500, 0.559, 0.600, 0.650, and 0.760 mm, each with its own part number
  • 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: RoHS-compliant (Directive 2011/65/EU as amended by (EU) 2015/863) and REACH-compliant; declarations available on request.
  • 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.

Frequently Asked Questions

What is Sn96.5Ag3.5 solder?

Sn96.5Ag3.5 is the eutectic tin-silver alloy: 96.5% tin and 3.5% silver, with no copper. It is one of the original lead-free solder alloys and melts at a single temperature of 221 °C.

How does Sn96.5Ag3.5 differ from SAC305?

SAC305 adds 0.5% copper and has 3.0% silver, giving a 217 to 219 °C melting range. Sn96.5Ag3.5 has no copper, slightly more silver, and a single 221 °C melting point. Select the alloy your assembly specification calls out.

What is the melt temperature of Sn96.5Ag3.5 solder balls?

221 °C. Because the alloy is eutectic, it melts and solidifies at that single temperature rather than over a range.

Which Sn96.5Ag3.5 diameters are available?

This page lists eleven diameters from 0.200 mm to 0.760 mm with corresponding part numbers. EasySpheres stocks diameters across the 0.050 to 0.889 mm range; contact EasySpheres for a size not listed.

Is Sn96.5Ag3.5 RoHS-compliant?

Yes. Sn96.5Ag3.5 is a lead-free alloy and is RoHS-compliant under Directive 2011/65/EU as amended; a declaration is available on request.

Why Buy Solder Spheres from EasySpheres

Ordering and Support FAQs

Can I order Sn96.5Ag3.5 solder spheres in small quantities?

Yes. EasySpheres supplies Sn96.5Ag3.5 solder spheres with a minimum order of 10,000 spheres and scales to production volumes. Request a quote for larger requirements.

How quickly do Sn96.5Ag3.5 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 Sn96.5Ag3.5 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 Sn96.5Ag3.5 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.
