Wire Bond picture

[Led-Time]

I was mucking around with a microscope type thing I bought to see if it could be used for some module repairs and a curious though crossed my mind, could I take a picture through the eyepiece, so I dug out my old Fuji Finepix point & shoot and captured this...

Looks pretty good don't you think... :D

Very good shot Klippie - what brand is the module? I notice a lot of the wire bonds have a wisker that comes back from the copper traces. I believe some manufacturers actually used those for handling purposes back in the early days. Legions of ladies with very steady hands, carefully placing those all day under a microscope for low wages :?

Great pic Klippie. What kind of microscope is it? I was thinking of getting something like that myself, for the same purpose.

ED,

Its a Hughes ladies module ( I bought the watch thinking it had a 29mm module in it DOH... I've been after one for ages you see ) there is a transparent cover over the LED's this may be causing a reflection of the wire bond wiskers your seeing.

redled,

Sorry I can't see any makers name or model on the microscope thingy its not a proper microscope either its like high power magnifying lenses on an arm. I'd like a real microscope but half decent ones make a lot of money on Ebay.

"magnifying lens on an arm" - sounds like a Bulova Accutron semi-microscope with large working distance used for adjusting the pawl finger on the complicated tuning fork movement.
a standard miscroscope wont give you that much working distance.
