Sesame paste is an ingredient in some Chinese and Japanese dishes; Sichuan cuisine uses it in some recipes for dandan noodles. Sesame paste is also used in Indian cuisine. In the
Solder paste time in this area is known as "Time Above Liquidus". A reasonably rapid cool-down period is required after this time. For a good soldered joint, the proper amount of solder paste must be used. Too much paste may result in a short-circuit, too little may result in poor electrical connection or physical strength. Although solder paste typically contains around 90% metal in solids by weight, the volume of the soldered joint is only about half that of the solder paste applied. This is due to the presence of flux and other non-metallic agents in the paste, and the lower density
