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 recently had our customer report a component failure trend of a few percent. Analysis indicates wire bond failure internal to a d-pak caused by what appears to be chlorine contamination. We're running a lead free process with aqueous wash. 700 co

Our first impulse would be to blame someone else. We'd send some of the DPAK from inventory to: * Supplier * Outside failure analysis laboratory ... for delidding and analysis

I have a Komax Iota 330. It's a great machine. Accurate, fast, easy to service. We cut plastic shrink tubing as small as 1/8" diameter, plastic convoluted wire loom, metal mesh wire loom, plastic air line, and more. We easily process more than one mi

I don't know if they make a shrink tube cutting machines, but Schleuniger makes a good wire cutting/stripping machine.

when I order a thermocouple wire for doing oven profiles, it comes in a standard length of 36 inches, will there be any effects if I were to cut the wire down to 9 inches? Will cutting change the readings?
