Sn63/Pb37 Electropure™ is a high purity alloy that is composed of 63% tin and 37% lead. Electropure is alloyed in a proprietary method that results in a low drossing, high wetting solder. The Electropure process reduces suspended oxides in the solde

Amen to that Patrick. I am from a traditional Engineering background myself - they never taught wave solder in school. My curriculum was mostly theory and labs. When I got out, I read all the soldering books available at the time and also watched s

Dave: Thanks for you Earl-Moonesqe explanations. To answer your 3 questions below: * If there�s no flux in the via, why does the sodder flow? I thought it was the flux that removed corrosion to increase wetting that allowed

The melting temperatures of most lead-free solder alloys are somewhat higher than that of eutectic Sn/Pb solder, and many of the alloys tend to wet typical contact pads less readily. This tends to narrow down the fluxing and mass reflow process windows for assembly onto typical organic substrates and may enhance requirements on placement accuracy. Flip chip assembly here poses some unique challenges. The small dimensions provide for particular sensitivities to wetting and solder joint collapse, and underfilling does not reduce the demands on the intermetallic bond strength. Rather, the need to underfill lead to additional concerns in terms of underfill process control and reliability. Relatively little can here be learned from work on regular SMT components, BGAs or CSPs.

Sn3.0Ag0.5Cu (SAC305) is the most popular near eutectic lead-free alloy used in the manufacturing processes. Over the last several years, the price of silver has dramatically increased driving a desire for lower silver alloy alternatives. As the results, there is a significant increase in the number of alternative low/no silver lead-free solder alloys available in the industry recently.In this paper, we'll present the performance and process capability of various low/no silver alloy solder pastes. Data from printability, wetting test, slump test, solder ball test, voiding, etc… will be discussed and compared with the control SAC305 solder paste. Benefits and concerns of using low/no silver alloy solder paste materials will also be addressed.
Lyra Reflow Oven is a soft soldering that realizes the mechanical and electrical connection between the solder ends of surface mount components or the pins and the printed board pads by remelting the solder paste pre-distributed on the printed board
