Metals Content in Printed Circuit Board Waste
This paper an presents analysis of metals in waste of printed circuit boards (PCB) covering types of PCB, segregated from PC computers, mobile phones, and mixed. The presented data identifies metals and other substances found in PCB waste based on elemental and technical analysis of PCBs. PCB categorization based on gold concentration is presented, resulting in two groups: electric and electron...
متن کاملCopper Leaching Behavior from Waste Printed Circuit Board in Ammoniacal Alkaline Solution
A novel energy-saving hydrometallurgical recovery process for copper from electronic scrap employing the Cu(I)-ammine complex has been presented on the basis of a thermodynamic consideration. In order to experimentally explore the feasibility of the leaching stage in this process, the copper leaching behavior from a printed circuit board (PCB) in ammoniacal alkaline solutions has been investiga...
متن کاملNovel waste printed circuit board recycling process with molten salt
The objective of the method was to prove the concept of a novel waste PCBs recycling process which uses inert, stable molten salts as the direct heat transfer fluid and, simultaneously, uses this molten salt to separate the metal products in either liquid (solder, zinc, tin, lead, etc.) or solid (copper, gold, steel, palladium, etc.) form at the operating temperatures of 450-470 °C. The PCB rec...
متن کاملPrinted circuit board inspection
This paper provides a general overview of immediate and long-term aims of the printed circuit board inspection project of The Robotics Institute. Its purpose is to highlight some of the significant issues specific to printed circuit board inspection and to provide a discussion of our basic thesis that machine inspection should be coupled with machine diagnosis of the causes of observed printed ...
متن کاملCopper Sulphate and Disinfection of Water
lime, which, added in even so small an amount as 0 000426 gramme to a hundred cubic centimetres of water, kills all the micro-organisms within two hours. The bacteria appear to be acted upon much more promptly than the other organic matter present. For the removal of the excess of the agent the addition of sulphite of sodium (0 000209 gm.) suffices, and an excess of this substance up to 50 per ...
