JHI IS ARIZONA’S SPECIALIST IN RECYCLING IC CHIPS

Ball Grid Array (BGA) IC (Integrated Circuit) chips contain precious metals, including gold, palladium, silver and copper; valuable materials to reap out of the recycling process, and JHI is very capable of full-metal extraction.

Recycling IC Chips is an excellent way to derive value from older, potentially-sunsetted systems in which they are used.

There are a variety of chips in the current market, and as the explosion of “smart” electronics continues, there will continue to be a corresponding level of growth in the IC market.  Further, the technology behind the Integrated Circuit development continues to progress. Seemingly on a day-to-day basis.  Thus, IC chip technology rapidly becomes obsolete.

This creates a vast market for recycle and reuse (if applicable).  JHI’s principal focus regarding the IC Chip is recycling, and with good reason.

There are a number of methods to use in recycling IC Chips, and JHI is well-versed in all current practices.

In all things recycling, JHI strives constantly to maintain a minimal footprint with regard to the environment, so some of the current methods in use to extract precious metals while recycling IC Chips are not practices that JHI applies.

In order to minimize the problem of pollution and to conserve limited natural resources, a method to recover the valuable metals such as gold, silver and copper present in the scrap integrated circuits involves roasting, grinding, screening, magnetic separation, melting and leaching is used to efficiently recover said precious metals.

ARIZONA’S USED IT EQUIPMENT BUYERS

First, JHI roasts scrap integrated circuit chips to 850 C to destroy their plastic resin sealing material.  Then we apply screening and magnetic separation to separate the metals from the resin residue.  The non-ferrous materials are mainly comprised of copper and could be melted into a copper alloy.  Non-ferrous materials containing gold, silver and copper were recovered at 100% by a leaching process in which thiourea was used as the leaching agent.

JHI selectively disassembles the IC Chip with a singular focus on weeding out hazardous and/or valuable components, which is indispensable in recycling IC Chips.  Mechanical/physical processing provides an alternative means of recovering valuable materials.

Mechanical processes, such as screening, shape separation, magnetic separation, eddy-current separation, electrostatic separation, and jiggling are widely utilized.  To take the process one step further, JHI tries to shred Chip materials typically below 5-10mm.

Consumer electronic equipment (brown goods), such as television sets, video recorders are most common, and its very costly to manually dismantle such products (mainly because brown goods contain very low-grade precious metals and copper.  JHI employs a mechanical recycling process as part of our initial IC Chip recycling.

So, as evidenced by the extensive process that is used to distill precious metals from used and discarded IC Chips, they to hold considerable value in precious metals, so recycling for extraction and reuse of materials provides worthwhile cost-benefit.
