Joint Board

The whole issue of needed data, as Dr. Currie pointed out, was addressed in a recently published report by the American Chemical Society. "Improving the Reliability and Acceptability of Analytical Chemical Data Used for Public Purposes, published by the Joint Board/Council Committee on Science of the ACS in May 1982 (see also CdEN 1982,, (23) 44 It tried to relate chemical analytical measurements to socio-political and regulatory needs.

When black pads are present, proper metallurgical bonding between the solder and the pad will not form during soldering. The occurrence of black pad is difficult to detect from the visual appearance of the PWB and solder joints. Boards with black pad can easily pass visual in-... 

General Brigham s recommendations were no doubt prompted in part by the action of the Joint Board in the summer of 1935 in confirming CWS responsibility for research and procurement of chemical warfare materiel for the Army, the Navy, and the Marine Corps. ...

Failure at the Washington and Geneva conferences in 1922 and 1925 to reach a ban on the possession rather than the use of chemical weapons (see chapter 8) strengthened the hand of the pro-CWS lobby. By 1934 the Joint Board (forerunners of the Joint Chiefs of Staff) had declared, The United States will make all necessary preparations for the use of chemical weapons from the outbreak of war. The use of chemical warfare, including toxic agents, from the inception of hostilities is authorized. .. ... 

The pulser/receiver HILL-SCAN 30XX boards satisfy DIN 25450. Typical applications are ultrasonie imaging systems for nuclear power stations and for aircraft, material characterization, transducer qualification, replacement of portable flaw detectors (inspections of welded joints), inspection of new materials, measurement systems with air eoupling. ...

Conformal coatings are protective coatings appHed to circuit board assembHes. They protect the interconnect conductors, solder joints, components, and the board itself they reduce permeabiHty to moisture, hostile chemical vapors, and solvents in the coating. Use of conformal coatings eliminates dendritic growth between conductors, conductor bridging from moisture condensation, and reduction in insulation resistance by water absorption. 

Gypsum board paper is a special three-ply paper manufactured from repulped newspapers. The face paper or cream face has the ply against the core unsized so that the gypsum crystals can grow into it, as this is the principal form of bonding between the core and facers. The middle ply is sized and the outer ply is more heavily sized and treated to control paint absorption. For the completed gypsum board system to work, the joint treatment and paper must absorb paint at the same rate. 

Electrolysis of solutions containing Au(CN)2 is widely used to recover gold from solution (electrowinning) [17]. The process is also used to deposit gold coverings for electrons (e.g. printed circuit boards, electrical connectors) and most recently for hip and shoulder joint replacement surgery.
