COB and wire bond

Electronics Forum | Tue Jun 04 19:33:16 EDT 2002 | rob_thomas

Dave's estimation is pretty conservative but there is a lot of equipment out there and a lot of people happy to make a sale.Implementing both mentioned processes it's difficult and time consuming .Even if you get good training from whoever sells you

COB and wire bond

Electronics Forum | Mon May 07 11:02:17 EDT 2001 | Singh

Hi all. I am looking into the implementation of the Chip on Board process with eutactic bonding and the then using either gold or aluminum wire to make wedge type wire bonding. Since I am totally new to this, can somebody guide me thru the process,

wirebonding

Finer pitch: Wedge bonding can be designed and manufactured to very small dimensions, down to 50 mm pitch. Processing speed: Machine rotational movements make the overall speed of the wedge bonding process less than thermosonic ball bonding. Alumin

On the main page of Smtnet towards the end of the opening paragraph states the following...Your " research continues in determining the reliability of thick film hybrid microcircuits and similar technologies using low-temperature, co-fired ceramics.

temperature induced IMC in wire bonds?

Electronics Forum | Tue Nov 15 09:31:27 EST 2005 | arclightzero

I have been reading a good deal about IMC (purple plague in particular) in gold wire/aluminum pad wire bonds. My company uses ultrasonic wedge bonding, and for the most part all of our bonding is gold/gold, however we have one particulr part that has

Wire Bonding fiducial mark specifications

Electronics Forum | Wed Jan 31 17:30:54 EST 2007 | GS

Thanks a lot flipit, I am not directly involved in this "problem" but is my friend that have his CM rejecting PCBs because it says the "+" mark (spokes lengths) are out of tolerances. It seams CM bonder's require tolerance +/- 0,05(? not sure). I d

soldering and bonding on gold PCB's

Electronics Forum | Mon Jan 07 20:37:15 EST 2002 | davef

For soldered areas, we like to keep gold thickness substantially below the maximum you propose. Search the fine SMTnet Archives for our discussions on the topic of acceptable levels of gold with solder connections. Let�s fix this �no one seems be s
