A Basic, Compact Low-Heat Polishing System to Assist with Chip-off Work
In today’s chip-off effort, heat can pose a challenge when removing some newer, more fragile chips from their PCBs, as too much heat can destroy a chip. Using a polishing system can eliminate this concern and provides a safer way to prepare a chip for reading. Employing a process that begins with cutting a chip out of PCB (using a dremel or milling machine), then “polishing” away the PCB material to expose the chip contacts, a chip can be prepared in a safe manner for reading. Teel Technologies is proud to off the Hi-Tech Diamond polisher, a cost-effective, benchtop system for any laboratory faced with the challenge of newer chips.
The Hi-Tech Diamond All-U-Need lap machine is manufactured with a 1/2″ arbor and powered by a 1/4 hp, heavy-duty, ball bearing, DC motor. This motor is variable speed so you can work at whatever pace you desire, delivering speeds from 800 rpm to 3,400 rpm. This portable machine can be used anywhere. Whether you’re at home, in the shop or on the road, this quiet machine won’t disturb others around you. It’s lightweight, rustproof and impact-resistant, making it even easier to travel with.
The coolant reservoir, which holds about a pint of water, prevents heat buildup while you work and removes dust particles so you don’t inhale any harsh chemicals. That pint of water will give you two to three straight hours of work without refilling. The black splash guard keeps water off you so you don’t get soaked while you work. Cleanup is as simple as it gets: Just remove the black spray shield, rinse with clean water and you’re ready to work again.
