Juan, Try Hamamatsu directly. (908) 231-1116 e-mail: usa@hamamatsu.com Ask for "RE-LOAD" pricing. Make sure you have the tube serial number and model available. Some units cannot be re-used. You will find the serial # on the side of tube housing. J

Terry, I use a VItechnology AOI and I'm very happy with it. I find the software to be very flexible. You will realize how much components vary from one manufacturer to another, so flexibility is important. The Omron machines are good at solder

Dave, Good to hear about VITechnology. Youre right about flexibility to deal with component variation. We have had problems with different batches causing rejects. When you say Omron for solder, do you mean solder paste or reflowed solder joints ?

I don't believe you'll get an exact zero flux with no-clean pastes. Water soluable yes, but I don't see it happening with no-clean; at least not this year. As for spatter, you should be able to control this. Can you define what you call "spatter"?

Hi, We maybe buy a MPM AP25hie, and the guy who sold the printer told me about a Dedicated tooling and a Universal Tooling...I not quiet sur of what is that, can someone explain it to me and what is the best option. Just for fun are you ready t

Kris, I assume with voids you mean acceptable solder coverage of pad and lead. As Dave mentioned I also have not seen any specific studies on voids, but workman ship standards exist about acceptable coverage of pad and lead (both consumer and MIL)

High temp balls (spheres for you PC types) They are non-eutectic balls. Do you have a reballer or stencil setup? If one device...may not be cost effective, but if many you can usually send back the the IC house for re-ball. There are only a handf

A small benchtop system uses a mask, tooled for your part, to arrange the solder spheres onto the BGA, after it has had the excess solder heat-vacuumed off and a new layer of flux applied. The spheres are poured into the cavity, excess decanted off.

Whether could we add some heating or cooling modules to the 8 zone reflow oven and convert the 8 zone to 12 zone or more?I 've never heard of anybody successfully done this.I think, this way, we could get more cost down.What's your opinions? Thanks®a

I've never heard of anyone doing this. Even if it were possible I can't believe it would be cost effective. If you absolutely need a 12 zone oven your best bet is to try and be a used/refurbed one if you can't afford a new one.
