Leaking Capacitors Muck up Motherboards

Published by

Just saw this at Techzonez.com ...... A mistake in the stolen formulation of the electrolyte in a capacitor has wrecked hundreds of PCs and may wreck still more in what is an industrywide problem.

Aluminum electrolytic capacitors with a low equivalent series resistance (ESR) are high-capacitance components that generally serve to smooth out the power supply to chips. Throughout 2002, they have been breaking open and failing in certain desktop PCs. Motherboard and PC makers contacted by IEEE Spectrum have stopped using the faulty parts, but because the parts can fail over a period of several months, more such failures are expected.

So far, the only motherboard maker to admit to the problem is ABIT Computer Corp. (Taipei), and the only major PC maker to acknowledge being affected is IBM Corp. But the problem is likely to be more widespread. Indeed, those who have repaired the damaged boards say that they have encountered crippled motherboards from Micro-Star International, ASUSTek Computer, Gigabyte Technology, and others.
