Frequently Asked Questions

What is the melting point of Sn42Bi58?

139 °C. Sn42Bi58 is a eutectic alloy, so it melts at that single temperature, roughly 80 °C below SAC alloys.

When should I use Sn42Bi58 solder balls?

Use Sn42Bi58 where the component or board cannot tolerate SAC reflow temperatures, or where a second, lower-temperature soldering step is required. Tin-bismuth joints are harder and more brittle than SAC joints and have a lower service temperature, so confirm suitability against the reliability requirement.

Which Sn42Bi58 diameters are available?

This page lists diameters from 0.125 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 Sn42Bi58 RoHS-compliant?

Yes. Sn42Bi58 is a lead-free alloy and is RoHS-compliant under Directive 2011/65/EU as amended; a declaration is available on request.

What size tolerance applies to Sn42Bi58 solder balls?

Maximum dimensional tolerance is ±4%, with typical measured tolerance of ±0.50% for 0.050 to 0.450 mm, ±1% for 0.500 to 0.550 mm, and ±0.83% for 0.600 to 0.889 mm. Sphericity deviation is less than 1.5%.

Ordering and Support FAQs

Can I order Sn42Bi58 solder spheres in small quantities?

Yes. EasySpheres supplies Sn42Bi58 solder spheres with a minimum order of 10,000 spheres and scales to production volumes. Request a quote for larger requirements.

How quickly do Sn42Bi58 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 Sn42Bi58 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 Sn42Bi58 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.
