SAC105 | Pb-free Solder Spheres
- Pb-free Solder Spheres
- Lowest cost Sn/Ag/Cu Alloy
- Excellent Fatigue Resistance
Product Description
LINQALLOY SAC105 Solder Spheres are lead-free Tin/Silver/Copper alloys that contain 98.5% Tin (Sn), 1% Silver (Ag), and 0.5% Copper (Cu) and is often written as Sn98.5Ag1.0Cu0.5. SAC105 Solder Spheres contain the least amount of silver of the industry standard lead-free solder spheres and are used by companies working with BGA, CSP, LBGA, PBGA and CBGA components who have made the transition to Lead-free (Pb-free) soldering.
Features:
- Lowest Cost Sn/Ag/Cu Alloy
- Excellent Fatigue Resistance
- Compatible with all Flux Types
- Excellent Solder Joint Reliability
- Best Wetting Sn/Ag/Cu Alloy
Each jar has a clear label on the lid specifying the solder ball diameter as well as a label on the front identifying the alloy type, the quantity of spheres in the jar, the date of manufacture, and the product lot (or batch) number. This batch number is also tied to a certificate of conformance that is also provided with the solder spheres and ensures the SAC105 solder spheres meet the following quality criteria:
- Tin (Sn): 98.5%
- Silver (Ag): 1%
- Copper (Cu): 0.5%
- Melting Temperature (Solidus): 220°C
- Melting Temperature (Liquidus): 225°C
- Spheroid Tolerance : Within 1.5%
Diameter Tolerance
- 0.075mm - 0.15mm (3-6 mils) : ±0.005mm (±0.2 mils)
- 0.20mm - 0.60mm (8-24 mils) : ±0.010mm (±0.4 mils)
- 0.65mm - 0.76mm (25-30 mils) : ±0.015mm (±0.6 mils)

| Specific Gravity Specific Gravity Specific gravity (SG) is the ratio of the density of a substance to the density of a reference substance; equivalently, it is the ratio of the mass of a substance to the mass of a reference substance for the same given volume. For liquids, the reference substance is almost always water (1), while for gases, it is air (1.18) at room temperature. Specific gravity is unitless. | 7.32g/cc | ||||||||
| Spheroid Tolerance Spheroid Tolerance The allowed % that a solder ball (solder sphere) can divert from being perfectly round and spherical. We take one lot of solder spheres and divide it into 4 smaller lots. Each lot is then checked with advanced visual inspection systems. If even 1 ball is out of spec, the entire batch is scrapped and reworked! | 1.5 % | ||||||||

| RoHS Compliant RoHS Compliant RoHS is a product level compliance based on a European Union Directive which restricts the Use of certain Hazardous Substances in Electrical and Electronic Equipment (RoHS). Products compliant with this directive do not exceed the allowable amounts of the following restricted materials: lead, mercury, cadmium, hexavalent chromium, polybrominated biphenyls (PBB) and polybrominated diphenyl ethers (PBDE), with some limited exemptions | Yes | ||||||||
Additional Information
What do I get when I buy SAC105 Solder Spheres from CAPLINQ?
The advantage of ordering solder spheres online at CAPLINQ.com is that you can be sure of the quality. The solder spheres you receive are originally manufactured solder spheres packed into jars with inert gas (nitrogen). We do not repack the solder balls we receive, so the jars you will receive have never been opened, thus ensuring the quality of the product you receive. The lid of the jar is also always sealed with a shrink-wrapped plastic wrap ensuring that the solder spheres do not oxidate in the jar.
