aiyoh... reading this, i feel like 1st year freshie onli....
graduated with a Diploma in Telco. & Computer Engineering
and also a Degree in Electronics and Computing,
but that was like 3++ years ago.... now almost forget everything alredi...
Anyway, I'm now working in the semiconductor manufacturing / assembly industry.. i.e we make the chips u used in those PCBs.
but don't ask about the internals lah... but if u wanna know how we manufacture leadframes, do die attach, wire bonding, molding, solder plate, window dejunk, singulation, testing, etc, etc then ask loh...

QUOTE(silkworm @ Oct 19 2005, 02:58 PM) You stick em on the board then stuff the whole board into an oven and cook it. Surface tension will pull the part onto the solder pads nicely. Inspect with an X-ray or ultrasound to make sure there aren't any shorts. Like baking a cake (except for the x-ray part  ). yup... the solder balls is already part of the BGA package... just use a reflow oven. the oven will have a precise control of the temperature ramp and duration. Also it's is done in Nitrogen gas to ensure parts don't oxidize. |

QUOTE(zybler @ Oct 25 2005, 09:34 PM) Erm... I'm a first year student on computer engineering from UTAR.. can add me to the list?  I've got a question lar.. erm.. anyone here knows where to buy electronics parts? Like those for PIC and 80x microcontroller? As well as those logic gates.. Me and my frens used to get parts from Farnell Electronics, around Seksyen 14 if I remember correctly. Prefer there to Pasar road. Of course Farnell sell it more expensive, but since company paying..... |
