PMTC SAC387 Pb-free Solder Spheres SAC387 Pb-free Solder Spheres

Main features

  • Pb-free Solder Spheres
  • For BGA and CSP components
  • Tin/Silver/Copper alloys

Product Description

LINQALLOY SAC387 Solder Spheres are Pb-free Tin/Silver/Copper Sn95.5Ag3.8Cu0.7 Industry standard solder spheres for BGA and CSP components used by companies who have made the transition to Lead-free (Pb-free) soldering.

Furthermore, 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 SAC387 solder spheres meet the following quality criteria:

  • Tin (Sn): 95.5%
  • Silver (Ag): 3.8%
  • Copper (Cu): 0.7%
  • Melting Temperature (Solidus): 217°C
  • Melting Temperature (Liquidus): 219°C
  • Sphericity : Within 1.5%

Diameter Tolerance

  • 0.1mm - 0.25mm (100µm - 250µm) : ± 0.0050mm (± 5µm)
  • 0.3mm - 0.45mm (300µm - 450µm) : ± 0.010mm (± 10µm)
  • 0.5mm - 0.89mm (500µm - 890µm) :  ± 0.020mm ( ± 20µm)

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

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!

Additional Information

 

What do I get when I buy SAC387 Solder Spheres from KRAYDEN?

The advantage of ordering solder spheres online at KRAYDEN.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.
