iNEMI Project on Process Development of BiSn-Based Low Temperature Solder Pastes

The 2017 iNEMI Board and Assembly Roadmap forecasts that, due to economic, environmental and technical drivers, use of low temperature solder pastes will increase significantly and reach 10% of all solder paste used for board assembly by 2021.

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, the addition of alloying elements and nanoparticles Sn-Bi solders improves the melting temperature, wettability, microstructure, and mechanical properties. Improving the brittleness of the eutecticSn-58wt%Bi solder alloy by grain refinement of the Bi-phase becomes a hot topic. In this paper, literature studies about melting temperature, microstructure, inter-metallic thickness, and mechanical properties of Sn-Bi solder alloys upon alloying and nanoparticle addition are reviewed

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 has a melting point of about 139°C. Experience so far indicates that such Bi-Sn alloys do not have the mechanical properties and microstructural stability necessary to deliver the reliability required for the mounting of BGA packages. Options for improving mechanical properties with alloying additions that do not also push the process temperature back over 200°C are limited. An alternative ...

█ Printed Circuit Board Assembly & PCB Design Forum

Component orientation -- Hi, We are facing the issue with Component orientation(Wrong orientation), during Proto build/NPI time in SMT for 1st board placement. We are not doing 1st board with STICKY board, directly placing the components with Paste board only. Pls suggest, How can we avoid the Wrong orientation during 1st board or any other check points need to be check during Pick &Place program. Thank you in advance

Leds are getting shifting during mounting when nozzles increase -- when i use only one nozzle to mounting 3535 cree power leds, it works good but when i use 2 or more nozzles, leds are getting rotated or upturned just after the nozzle relaese the led. it's like nozzle throws the led not mounts. But not all the leds have this problem. If we have 100 leds to be places, %30 of them is placed good and others have the situtation i mention about. Thank you. (Machine is panasonic cm)
