Q: Are solders somewhat less convenient for hand-soldering due to their generally higher melting points and tendency to dissolve copper wire? ¶
A: Yes, and but have been increasing in use due to the environmental benefits of avoiding lead-based electronic components.
Q: Are solders used that will pass assay? ¶
Q: Was solder still used until the 1980s because it was thought that the amount of lead that could leach into water from the solder was negligible from a properly soldered joint? ¶
Q: Are solders frequently "thermosetting", as their melting temperature after recrystallization becomes significantly higher? ¶
A: Yes, this allows soldering the parts together at lower temperature than the subsequent bake-out without remelting the joint afterwards.
Q: Is solder also often used for repair work for the same reason? ¶
Q: Are solders used for brazing? ¶
A: Yes, and melt at higher temperatures.
Q: Are solders available as frit powder with grain size below 60 micrometers? ¶
Q: Are solders used by two-thirds of Japanese manufacturers for reflow and wave soldering? ¶
A: Yes, and by about 75% of companies for hand soldering.
Q: Is solder used? ¶
A: Yes, and e.g., for joining together parts of cathode ray tubes and plasma display panels.
Q: Are solders used: vitreous? ¶
A: Yes, and devitrifying.
Q: Is solder also used in manufacturing to join metal parts that cannot be welded? ¶
Q: Are solders frequently used in electronic packaging? ¶
Q: Are solders useful in applications like subminiature vacuum tubes or for joining mica windows to vacuum tubes and instruments? ¶
A: Yes, Thermal expansion coefficient has to be matched to the materials being joined and often is chosen in between the coefficients of expansion of the materials.
Q: Are solders prone to corrosion? ¶
A: Yes, and especially in presence of chloride ions.
Q: Is solder heated would risk damaging delicate circuitry? ¶
Q: Are solders used to join glasses to other glasses? ¶
A: Yes, and ceramics, metals, semiconductors, mica, and other materials, in a process called glass frit bonding.
Q: Are solders frequently used for glass-to-metal seals and glass-ceramic-to-metal seals? ¶
