blu ray drive not reading discs

Took ps3 model cech-a01 apart to reflow the chips. Put it back together and when I got to reattaching the blu ray drive I notice some black debris on the ribbon going into ps3 motherboard. It was the black tab that secures the ribbon into the motherboard. Tried taping it on but holding it securely in place seemed to be the only thing to make the blue light blink. Still wasn't fully reading the disc, but ill investigate that after the more pertinent issue is resolved. Can I buy one of those black tabs and is it easy to install without breaking it?
