The bonding between the glass or ceramics and the glass solder can be either covalent, or, more often, van der Waals. [12] The seal can be leak-tight; glass soldering is frequently used in vacuum technology. Glass solders can be also used as sealants; a vitreous enamel coating on iron lowered its permeability to hydrogen 10 times. [13]
Came glasswork includes assembling pieces of cut and possibly painted glass using came sections. The joints where the came meet are soldered to bind the sections. When all of the glass pieces have been put within came and a border put around the entire work, pieces are cemented and supported as needed. [1]
1×6 pin header (one row) 1×6 female header (one row) A pin header (or simply, header) is a form of electrical connector. A male pin header consists of one or more rows of metal pins molded into a plastic base, often 2.54 mm (0.1 in) apart, though available in many spacings. [1] Male pin headers are cost-effective due to their simplicity.
For all of the above connectors, the computer manufacturer typically attaches a female IDC connector onto one end of a ribbon cable, and later slides that connector onto a matching male box header or pin header on the computer motherboard.
The pin brazing unit contains all the equipment and tools required to make safe cable connections. A welding generator may also be utilized as a power source wherever a battery unit may be impractical or a great many connections need to be made in such places as pipe-coating yards or lay-barges etc.
Solder-bucket (or solder-cup) contacts have a cavity into which the stripped wire is inserted and hand-soldered. Insulation displacement contacts (IDCs) allow a ribbon cable to be forced onto sharp tines on the back of the contacts; this action pierces the insulation of all the wires simultaneously. This is a very quick means of assembly ...
When potting a circuit board that uses surface-mount technology, low glass transition temperature (T g) potting compounds such as polyurethane or silicone may be used. High T g potting compounds may break solder bonds through solder fatigue by hardening at a higher temperature because the coating then shrinks as a rigid solid over a larger part ...
Soldering and brazing are thought to have originated very early in the history of metal-working, probably before 4000 BC. [2] Sumerian swords from c. 3000 BC were assembled using hard soldering. Soldering was historically used to make jewelry, cookware and cooking tools, assembling stained glass, as well as other uses.
