Lead-free SMT Soldering Defects How to Prevent Them

Tin-Silver-Copper alloys are the primary choice for lead-free SMT assembly. Although there are other options available such as alloys containing bismuth or indium and other elements, tin-silver-copper solders, also known as SAC alloys are by far the most popular.

How to Profile a PCB.

An optimal reflow profile is one of the most critical factors in achieving quality solder joints on a printed circuit board (PCB) assembly with surface mount components. A profile is a function of temperatures applied to the assembly over time. When graphed on a Cartesian plane, a curve is formed that represents the temperature at a specific point on the PCB, at any given time, throughout the reflow process.

Best Practices Reflow Profiling for Lead-Free SMT Assembly

The combination of higher lead-free process temperatures, smaller print deposits, and temperature restraints on electrical components has created difficult challenges in optimizing the reflow process. Not only are the electronic components and the PWB at risk, but the ability to achieve a robust solder joint becomes difficult, especially if the PCB is thermally massive. In addition, ...

Effect of Reflow Profile on SnPb and SnAgCu Solder Joint Shear Force

Reflow profile has significant impact on solder joint performance because it influences wetting and microstructure of the solder joint. The degree of wetting, the microstructure (in particular the intermetallic layer), and the inherent strength of the solder all factor into the reliability of the solder joint. This paper presents experimental results on the effect of reflow profile on both 63%Sn 37%Pb (SnPb) and 96.5%Sn 3.0%Ag 0.5%Cu (SAC 305) solder joint shear force. Specifically, ...

Reflow Experiment

An experiment was recently performed ACI Technologies for a customer that was interested in comparing the wetting of lead-free solders with varying temperature profiles and atmospheric conditions. In order to deliver an objective measurement of solder wetting (in addition to subjective inspection analysis), a simple wetting indicator pattern was added to the solder stencil in an area on the test vehicle that had exposed and unused copper.

█ Printed Circuit Board Assembly & PCB Design Forum

Reflow Oven Profile Optimization -- Hi everyone, I am having some issues achieving consistent reflow profiles for different PCB designs due to variations in thermal mass. I need advice on optimizing my reflow oven settings to handle these differences effectively. I want to know the best tools and methods for thermal profiling; determining optimal zone temperatures; adjusting conveyor speed, and managing thermal mass differences. Any tips for software tools and automation solutions would also be greatly appreciated. Thanks in advance for your help! Thank you greatjennymsbi

DEK print limit -- Using horizon 02i, I'm trying to program the print area of a board outside of just the board width. It seems that print front and print rear limit has no effect on the print area. Any suggestions on a solution?
