Abstract:
1. A method of cleaning electrical contacts on an integrated circuit module using a slotted, complementary-dual-housing mechanical cleaning apparatus comprising a spring-actuated tension adjustment mechanism, a wipe top holder/tension adjustment area, a tension/adjustable cleaning area, a wipe opening, a wiping cloth, a wipe lock, a plurality of cleaning head alignment pins, a plurality of cleaning head holes, a magnet, and a reservoir, the method comprising: loading an integrated circuit module having a first surface and a second surface onto the slotted, complementary-dual-housing mechanical cleaning apparatus, the integrated circuit module having a first plurality of electrical contacts providing a first cleaning substrate disposed on the first surface and having a second plurality of electrical contacts providing a second cleaning substrate disposed on the second surface; inserting the wipe cloth into the wipe opening along the tension/adjustable cleaning area such that it is secured in the wipe top holder/tension adjustment area and filling the reservoir with a cleaning agent; inserting the integrated circuit module into the tension/adjustable cleaning area such that the first plurality of electrical contacts are capable of contacting the wiping cloth by moving along a predetermined wiping path; fastening the wipe lock and tightening the spring-actuated tension adjustment mechanism such that the magnet, the plurality of cleaning head alignment pins and the plurality of cleaning head alignment holes maintain the slotted, complementary-dual-housing mechanical cleaning apparatus in a pressure-coupled state; contacting the first cleaning substrate with the wiping cloth; moving the integrated circuit module through the predetermined wiping path such that at least one electrical contact on the first cleaning substrate is cleaned and decontaminated; unfastening the wipe lock and loosening the spring-actuated tension adjustment mechanism such that the magnet, the plurality of cleaning head alignment pins and the plurality of cleaning head alignment holes no longer maintain the slotted, complementary-dual-housing mechanical cleaning apparatus in a pressure-coupled state; removing the integrated circuit module from the tension/adjustable cleaning area; reorienting and re-inserting the integrated circuit module into the tension/adjustable cleaning area such that the second surface is oriented so that the second plurality of electrical contacts are capable of contacting the wiping cloth by moving along a predetermined wiping path; fastening the wipe lock and tightening the spring-actuated tension adjustment mechanism such that the magnet, the plurality of cleaning head alignment pins and the plurality of cleaning head alignment holes maintain the slotted, complementary-dual-housing mechanical cleaning apparatus in a pressure-coupled state; contacting the second cleaning substrate with the wiping cloth; moving the integrated circuit module through the predetermined wiping path such that at least one electrical contact on the second cleaning substrate is cleaned and decontaminated; unfastening the wipe lock and loosening the spring-actuated tension adjustment mechanism such that the magnet, the plurality of cleaning head alignment pins and the plurality of cleaning head alignment holes no longer maintains the slotted, complementary-dual-housing mechanical cleaning apparatus in a pressure-coupled state; and removing the integrated circuit module from the tension/adjustable cleaning area.
