WTF?!!, PinkStuff forming on PCB?!...
 

Has anyone else ever seen this phenominum before?. it seems to happen around surface mounted resistors (I think they're resistors), it looks like bubblegum!, but sometimes it's hardened. It is NOT something that has 'dropped' or 'stuck' to the PCB from outside or above. I have it on my IBM60GXP 40gig harddrive at the moment(hardened), on the small section of PCB...
My friend also had this (but softer like gum) on a Leadtech Gf2PRO that died a mysterious death, it was on the resistors on the back of the GPU in his case...

Can somebody shed some light on this subject for me?...

Has anyone else had or seen or even heard of this before?...

It's a form of glue used when populating the bare PCB, it can be a real arse when you want to remove a SMD componant. Depending on the methods used in the contruction of the product, it will either be tacky or hard like Arildite. If you ever plan on doing some rework on a componant that is resined down, be very carefull, that "bubblegum" is sometimes strong enough to hold the centre of the part down whilst the rest/legs snap off around it. (Been there, done that :( )
