Low Melting Temperature Sn-Bi Solder: Effect of Alloying and Nanoparticle Addition on the Microstructural, Thermal, Interfacial Bonding, and Mechanical Characteristics

Sn-based lead-free solders such as Sn-Ag-Cu, Sn-Cu, and Sn-Bi have been used extensively for a long time in the electronic packaging field. Recently, low-temperature Sn-Bi solder alloys attract much attention from industries for flexible printed circuit board (FPCB) applications. Low melting temperatures of Sn-Bi solders avoid warpage wherein printed circuit board and electronic parts deform or deviate from the initial state due to their thermal mismatch during soldering. However ...

A Study On Process, Strength And Microstructure Analysis Of Low Temperature SnBi Containing Solder Pastes Mixed With Lead-Free Solder Balls

As the traditional eutectic SnPb solder alloy has been outlawed, the electronic industry has almost completely transitioned to the lead-free solder alloys. The conventional SAC305 solder alloy used in lead-free electronic assembly has a high melting and processing temperature with a typical peak reflow temperature of 245°C which is almost 30°C higher than traditional eutectic SnPb reflow profile. Some of the drawbacks of this high melting and processing temperatures are yield loss due to ...

Advantages of Bismuth-based Alloys for Low Temperature Pb-Free Soldering and Rework

The increased function of personal electronic devices, such as mobile phones and personal music devices, has driven the need for smaller and smaller active and passive components. This trend toward miniaturization, occurring at the same time as the conversion to RoHS-compliant lead-free assembly, has been a considerable challenge to the electronics assembly industry. The main reason for this is the higher reflow process temperatures required for Pb-free assembly. These higher temperatures can thermally damage the PCB and the components. In addition, ...

Optimising Solder Paste Volume for Low Temperature Reflow of BGA Packages

The need to minimise thermal damage to components and laminates, to reduce warpage-induced defects to BGA packages, and to save energy, is driving the electronics industry towards lower process temperatures. For soldering processes the only way that temperatures can be substantially reduced is by using solders with lower melting points. Because of constraints of toxicity, cost and performance, the number of alloys that can be used for electronics assembly is limited and the best prospects appear to be those based around the eutectic in the Bi-Sn system, which ...

█ Printed Circuit Board Assembly & PCB Design Forum

"Recycling" Paste? -- I'm hoping to hear what others are doing regarding "recycling" paste. By recycling paste, I'm referring to an operator taking the paste left over on a stencil after a work order is done and putting it either back into the jar it came from originally or depositing it into another jar to be used later. In my experience, any paste not used still on the stencil should go right into solid waste, but a collogue insisted the paste was still good as long as it was not on the stencil longer than 8 hours. How does the industry feel about this practice? Yes, it would save money on paste, but doesn't this have the potential to introduce contaminants to your paste and thus defects? What is the industry standard for handling this issue in a contract manufacturing environment?

TAPE AND REEL MATERIALS AND LOCAL SERVICES -- Do most of the circuit board assembly houses ever go out for tape and reel services when they can only get parts in bulk.
