Soldering Materials

Tin-Lead and Lead-Free Solder Spheres

CAPLINQ is proud to offer the highest quality solder spheres at some of the markets' best prices. Be sure to read this article to find out makes our high quality solder spheres so great. CAPLINQ offers not only a broad range of tin/lead and leadfree solder spheres, but also offers the industry's widest range of solder ball diameters ranging from 60 micron to 890 micron (2.4 mil to 35 mil).

Pb-Free Spheres SAC105, SAC125N SAC305, SAC387, SAC396, SAC405, SnAg or another alloy?

After many years of testing and debating, and with specific exceptions, the semiconductor industry has largely settled on the use of Tin (Sn), Silver(Ag), Copper(Cu) - or SAC - alloy for the assembly of lead free products. Although the SAC alloy has been settled, which SAC alloy to use is still up for debate. North American and Europe manufacturers favor SAC305 (Sn3.0Ag0.5Cu), while Asian manufacturers generally favor SAC405 (Sn3.8Ag0.8Cu).

SAC305 was first developed by Senju technology, who own the patents herefore. As such, manufacturers are required to pay a license to produce SAC305 which is built into the price charged to customers. SAC305 however has the benefit of being less expensive to produce than SAC405 owing to the lower silver content. This said, studies indicate that there is no significant reliability difference between SAC305 and SAC405, and so CAPLINQ continue to support both SAC305 and SAC405.

High Tech Tin

CAPLINQ is not only able to supply the alloys and purify the solder material, but it has an innovative diameter and spheroid selecting system of solder balls and an advanced anti-oxidation technology that actually dopes an anti-oxidation element into the alloy in addition to its OSP surface coating process.

Not only are our solder spheres High-Tech, but they are made from a unique uniform droplet spraying technology that far outperforms competitors in terms of productivity. This combination of high technology and high productivity allow CAPLINQ to offer its customers the best value for the best product.

Low volume flexibility, high volume pricing

CAPLINQ maintains an inventory of many sphere alloys and sizes, and we specialize in the fulfillment of small orders. CAPLINQ also offers volume breaks and discounts for our higher volume customers.
