Difference between solid crystal solder paste and normal solder paste

there are significant differences between solid crystal solder paste and ordinary solder paste in terms of composition and particle size, packaging and storage, use and process, and performance requirements.When choosing to use, you need to choose according to the specific application scenarios and soldering requirements.

Improvement of Sn-Bi Low-Temperature Solder Paste by Adding Ag and In

Sn-Bi eutectic solder paste has low soldering temperature requirements and can be soldered at low temperatures. This solder paste is important in the solder market due to its advantages, such as low-temperature soldering and high tensile strength. However, Bi is a brittle metal and prone to segregation in the solder during the heating process. The

How to improve the mechanical reliability of SAC solder paste

SAC series solder paste is a common medium-temperature solder in semiconductor packaging. This type of solder paste can be used for soldering work at relatively high temperatures, and the strength after soldering is considerable. However, as the thermal stress on the solder joint accumulates, there is a certain degree of deformation between the sol

Epoxy Flux on POP Laminated Packages

For mobile devices such as mobile phones, area array packages such as BGAs, CSPs or POPs are prone to drop failures and need to be reinforced when they are assembled onto printed circuit boards. While underfill is an alternative solution, it increases manufacturing costs and reduces temperature cycling reliability due to the additional curing steps
