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.

I have lots of experience with thermosonic gold ball bonding. You can read the literature and you will probably find some papers that say you can do it. I have never been able to do it. We gold ball bond all day long with little problems at all bu

The paper Dave posted the link for is great. I have to go back and read it in depth. I can build prototypes by wirebonding to ENIG. I can do it on a manual wirebonder but I don't have the patience to do it on a magazine to magazine automatic machi

I don't have a plasma cleaner either. It will help a lot. Actually I don't clean at all. Our wirebond pads are far enough away so the flux residue does not get on the wirebond pads. That's what we think anyway. I am sure we have some degree of c

Does anyone know if I will have problems soldering surface mount components to an all hard gold plated PC board. We want to use hard gold similar to gold used for edge fingers because our customer is concerned about wear and conductivity of connect

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

Does anyone know of any vendors who can supply "dummy" parts to practice ball wire bonding of gold to help train/certify operators? Thanks BWET
