Granted: 1999-06-01
Abstract: An automatic welder is used in an internal welder unit (30) which travels along the interior of a pipeline and provides the interior weld passes at the junction of abutting pipe joints (32, 33). The inter nal welder unit (30) has an electronic control system which includes a plurality of microprocessor control units (92, 94, 96, 98), eac h of which performs specific functional operations for the internal welder unit (30). The control system directs the operation of o rbiting internal welders (140) to have a zero or slow travel speed at a start point to ensure a high reliability of arc initiation. Af ter the arc is started, the travel speed of the internal welders (140) is accelerated to a high speed rate for the majority of the weld p ass. At then end of the weld pass, the welders (140) travel rate and wire feed rate are suddenly reduced to zero for the weld termina tion.

Title: Uniformity of copper etching in the fabrication of multilayer printed circuit boards
Inventor: LAL SUDARSHAN
IPC: C23F1/00
Filed: 1992-04-23
Granted: 1997-01-14
Abstract: This invention is a process for etching copper sheets on insulating boards for use in fabricating multilayer printed circuit boards. The improvementresides in adding to a standard copper etching solution certain alkyltrimethyl ammonium chlorides with alkyl chain lengths ranging from 6 to 20 carbon atoms inamounts sufficient to yield intermediate kinetics behavior. Of special interest are dodecyltrimethyl ammonium chloride, hexadecyltrimethyl ammonium chloride and octadecyltrimethyl ammonium chloride present in an amount of from 0.01 to 1.0 wt%. A silicon-based antiforming agent may be added in amounts of from 0.05 to 2.0wt. % to prevent an unacceptably large amount of foam from occurring during etching. With this formulation, the rate is mass transport controlled at low rates and almost independent of mass transport at high rates due to the inhibition of the surface reaction rate. As a result, non-uniformities in etch rates due to variations in mass transport conditions in processing equipment may be eliminated.  This unique formulation could significantly improve the yields presently obtained in manufacturing as well as allow the processing of fine-line multilayer circuit boards.
