Associated Press Writer CAIROâEgypt displayed on Monday newly discovered tombs more than 4,000 years old and said they belonged to people who worked on the Great Pyramids of Giza, presenting the discovery as more evidence that slaves did not build the ancient monuments.
Wave soldering is used for both through-hole printed circuit assemblies, and surface mount.In the latter case, the components are glued onto the surface of a printed circuit board (PCB) by placement equipment, before being run through the molten solder wave.lux in the wave soldering process has a primary and a secondary objective. The primary objective is to clean the components that are to be soldered, principally any oxide layers that may have formed. There are two types of flux, corrosive and noncorrosive.
Indium Corporation offers a variety of state-of-the-art and traditional wave soldering products that meet IPC J-STD, Department of Defense, and telecom specifications, as well as customer-specific commercial specifications for wave and selective soldering operations.ave soldering flux is the heart of the wave soldering operation. There are many types of soldering fluxes. Picking the correct flux chemistry depends on a number of factors, including: 1  The solderability level of the parts to be assembled. 2  The type of finish or coating used on the assembly. 3  The flux application method.
