what are your grading criterias? All of these work pretty good but have differences in the "bells and whistles" I like the Air-Vac DRS24 (no exp. with the 22) because of the large under heater and thermo-couple control. but it is very slow and costl

Hello - I am currently evaluating uBGA rework and X-Ray inspection solutions. I would like any advice/warnings etc. regarding suppliers and equipment. I have already researched through the threads in this forum and have created a list of recommended

When we need to apply paste during BGA rework we normally order a stencil from our stencil vendor. In most cases all we need to do is tell them the assembly and location plus quantity and they do the rest for us. Usually we'll have several types of a

Ask Air Vac (US) or Zevac for EU and ASIA. They have now a DRS-24 upgrading Kit for Leed-Free, main change is in the bottom heater. Air Vac- Zevac, made the ONIX series, the follow on of DRS models. Regards.....GS

Hi ... We use DRS24C Air-Vac machines for placing BGA devices, and have been having problems with shorts on corners of one device in particular, its a PBGA and its size is 4.5cm square and 15grams weight. When the component is picked up and the com

Never heard of the DRS-22C. I have had a DRS-22 for several years now. Purchased it when we started doing BGA's. The operators like it - good optics (split view), built like a tank, X-Y table easy to manipulate for alignment. I like it because I ca

I have been using an Air-Vac DRS-22 for almost two years with very good results. Once a profile is developed it is very repeatable. The DRS-22 is no longer available, however. It has been replaced by the DRS-24. Unfortunately, the DRS-24 has a lo

Not sure about that model, but I've used several DRS 22's and find them easier to use than the DRS24 I inherited at my current place. The lack of automation makes doing things yourself easier. The newer automated machines need more programming. I'

No, $60K is for the DRS-24 which has replaced the DRS-22. The 24 adds more bells and whistles, like motorized Z axis. I think they are pricing themselves out of the market, although I understand they are offering a stripped down 24 which is essenti

Omid, I have used the DRS24 for many years and have had similar problems with what you are talking about. I do not have any documents but I will tell you what I have seen. It sounds like an inconsistant collpse of the BGA. If one side of the BGA col
