following: in the waving soldering process, the temperature of PBGA solder joint reached to high temperature (in the experiment test, the peak was 186oC), which exceeded the melting point of mixed solder ball, so the mixed solder ball partially melt and kept at liquid state during the cooling period (from the peak temperature to the solidification
long life and achieving the perfect melting process. A wall built into the bottom of the melting end, which is also called barrier, and a deep refi ning part increase the fl exibility and glass quality. This furnace type can be also equipped with electric boost-ing in order to increase melting capacity and fl exibility.
The hot chamber process is used for metal that (a) have low melting points and (b) do not alloy with die material, steel; common examples are tin, zinc, and lead. 4.2 Cold Chamber Die Casting Process In a cold chamber process, the molten metal is poured into the cold chamber in each cycle.

duced as a by-product of tin smelting. The metal is also extracted from con centrates by reduction with sodium or fused-salt electrolysis; tantalum car bide is produced by carburization of Ta 2 0 s or tantalum hydride. Sintering, electric-arc melting and electron-beam melting are used to refine and purify raw tantalum. Tantalum's unique

manufacture of such glass is in four phases: (1) preparation of raw material, (2) melting in a furnace, (3) forming and (4) finishing. Figure 11.15-1 is a diagram for typical glass manufacturing.
Tin-Lead Fusing Fusing, or reflow, is the process of melting codeposited tin and lead just long enough to form the alloy called solder. (See Fig. 20-1.) Prior to fusing the surface of the tin-lead has few of the properties of solder, and is esthetically unappealing. Why is it that tin-lead is almost universally reflowed? 1.
