Mid Temperature Solder Paste Sn64.7Bi35Ag0.3

Mid temperature solder paste LF-04 Sn64.7Bi35Ag0.3 To meet the demand of high-density and memory/logic options for sophisticated electronic devices, many assemblers are evaluating package on package (PoP) technology. PoP assemblies allow for higher electronic functionality per unit circuit board area, and allows low cost product memory customization, and highly flexible manufacturing. Unlike PoP flux, BBIEN LF-04 Sn64.7Bi35Ag0.3 solder paste uses flux and solder powder, to minimize defects associated with non-planar processor/memory combinations during the reflow process.

Brief Introduction

BBIEN is a specialized solder pastes manufacturer in China, LF-04 Sn64.7Bi35Ag0.3

Solder paste is silver gray appearance, made up with metal powder and some active resin mixture. It’s specific gravity from 7.2 to 8.5. They are available for immediate delivery in jars, cartridges, syringes and can/box packing. They could be applied for your SMT technical requirements. We offer a short turn around time on orders and can ship to meet your just-in-time requirements. LF-04 Sn64.7Bi35Ag0.3 RoHS standard Pb-free bismuth tin solder paste is designed for middle temperature,its melting point from 138degree to 187degree Celsius.


BBIEN LF-04 Sn64.7Bi35Ag0.3 offers a full line of technologically advanced solder pastes developed to provide high throughput and yield, and lowest cost of ownership for a wide range of applications.  Our offering includes leading lead-free, no-clean, halogen-free solder paste technologies for applications such as fine feature printing, low temperature processing, and many others.  

Solder pastes are available in a wide range of alloy Sn-Bi-Ag also offered in solder bar, preforms, wire, and spheres for assured alloy compatibility and stronger solder joints.  BBIEN LF-04 Sn64.7Bi35Ag0.3 solder pastes conform to our customers’ unique processes, as well as the challenging environmental regulations they are required to follow.

The use of LF-04 Sn64.7Bi35Ag0.3 solder paste can help reduce costly defects associated with soldering known good memory devices to known good processor packages by bridging gaps that flux alone may not.
