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,

4 wire per sec ... you figure how many you need] Encapsulation ~$120K for a dispenser [10 sec per die ... you figure how many you need] plus a cure oven ~$100k Throw in a another ~$100k for marking and cleaning Check the September 2000 SMTnet New

Singh, The equipment varies in price. We make a wire bonder called the HW27U-H Wire Bonder. This is a gold to gold wire ball bonder. The substrate size you mention is within the area we can take into the machine. The key is the bonding area.

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

We have 2 CS9100 Schleuniger wire cut/strip machines. They do not have the DISPLAY/PC switch on the back of the CPU card. THe two machines come up PC mode. Any one know of a jumper setting on the CPU board that will allow the machnies to run in DI

I am shopping for a fine magnet/manganin wire stripper. Something to strip a variety of coatings from Formavar to Teflon off of 30awg and up wires. Something easy to use and set up. Anyone got one they can recommend? Thanks coeps

Hi All, Has anyone seen or used equipment that is capable of automating the process of attaching hookup wire directly to a large SMT pad? Soldering, ultrasonic? I'm looking to see if there is a machine that is capable of automatically taking a tef

We like to use "enameled wire" that can be stripped by hot solder. Formvar [105�C] will not do that. Formvar was designed to with stand the hot oil seen in transformers. So, it requires either chemical or mechanical stripping. Most polyurethanes

Fine magnet wire responds well to abrasion stripping. Here's one I've used: http://www.carpentermfg.com/magnet.htm Teflon requires a different kind of stripper called a twin blade rotary stripper or a precision die stripper because it's subject to
