Interconnection Evaluation Technology for Printed Wiring Boards
As a developer of world-class products including server and network devices, Fujitsu recognizes the printed wiring board (PWB) as a core component among the various components of those products. One basic element supporting high-quality PWBs is through-hole interconnection reliability. Existing methods for evaluating interconnections typically involve temperature cycle tests that subject the PW...
متن کاملRecovery of Tin and Copper by Recycling of Printed Circuit Boards from Obsolete Computers
This paper presents the experimental results for the leaching of printed circuit boards (PCB) from obsolete computers for extracting and recovering tin and copper by means of leaching followed by precipitation. Printed circuit boards were dismantled, cut into small pieces, and fed into a cylinder mill. The powder obtained was leached by using the aqueous solutions 2.18N H2SO4, 2.18N H2SO4 + 3.0...
متن کاملLeaching studies for metals recovery from printed circuit boards scrap
In this paper, the leaching behavior of the major metals present in printed circuit boards waste is evaluated, aiming at its recycling by hydrometallurgy. Several leachants were compared (sulfuric, hydrochloric and nitric acids, at 2 M H concentration), at temperatures of 25oC and 90oC and 4 hours of reaction time. Sulfuric acid leaching was not very promising concerning metals dissolution bein...
متن کاملRecovery of Gold, Silver, Copper and Niobium from Printed Circuit Boards Using Leaching Column Technique
Nowadays, over 300 tons of Au are used in electronic equipment each year with other precious and strategic metals such as Ag, Pt, Pd, Cu, Nb, Ta, etc.. After the use-phase, the electronic devices become electronic waste (e-waste); consequently it is important to consider e-waste as a secondary supply for the recovery of these metals. This paper presents the recovery of Au, Ag, Cu and Nb from PC...
متن کاملRecovery Of Copper From Printed Circiut Boards Through Electrolytic Process –A Case Study
Printed Circuit Boards (PCBs) collected from local sources were used for recovering copper by electrolytic process, using a laboratory reactor setup of working volume 15 liters and nitric acid for dissolution. Copper plate was used as the cathode and graphite rod as the anode for the deposition process. Five durations were adopted both for the dissolution and deposition processes. Based on the ...
