  • Humidity and Solder Paste - Avoid Issues
    As a rule, solder pastes and solder flux (tacky flux), be they no-clean (rosin/resin based) or water washable, do not react well to moisture. Humidity and Solder Paste Do Not Mix - Eric Bastow | INDIUM. Indium Corporation(R). Indium Corporation Blogs. Select an area to search All Web Pages Only
  • Soldering a copper tube to a brass flow valve [IH]
    To heat 1 3/4", 3" and 6" diameter brass slip rings and a sheathed copper wire. assembly to 3600 F for soldering within three (3) to six (6) seconds. Currently. production is accomplished by using a soldering iron and stick feeding rosin. cored solder. This process leaves unwanted solder

  • The use of alkenyl succinic
    began to have an influence on the traditionally used rosin/alum sizing systems, so suppliers of these products began to look at alternatives. Although there were a broad variety of obscure systems available, the main alternatives were: a) Variations on the rosin system, that would allow
  • The conversion
    sizing system in conjunction with calcium carbonate. Laboratory investigations and mill trials were carried out to determine the feasibility of converting the rosin/kaolin system used for the production of white top linerboard at Sappi Ngodwana to an alkenyl succinic anhydride (ASA)/calcium carbonate
  • The conversion of a kraft linerboard machine
    to determine the feasibility of converting the rosin/kaolin system used for the production of white top linerboard at Sappi Ngodwana to an alkenyl succinic anhydride (ASA)/calcium carbonate system. During the successful conversion, numerous quality improvements were seen. These included improved coverage
