SOLIDIFICATION/STABILIZATION OF NONVALUABLE RESIDUE FROM WASTE PRINTED CIRCUIT BOARD ASSEMBLY

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...

Novel 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...

Printed 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 ...
