Hi, Can I get some opinions on Orbotech AOI from actual users of this brand? Ease(or difficulty)of programming,reliability, customer support, etc. Thank you.

We have the Trion machines. Orbotech support has been more than fair. The learning curve for our particular machines is steep. As with any equipment you get out of it what you put into it. The machine does point out defects well, but the statistics need to have defects trained in to aid in this. It is a good tool for SMT and through hole inspection.

Only 1 response? This must not be a very popular brand.

No, Orbotech is pretty popular wordwide I'd say. This is suppose to be a technical forum, not an "opinion" forum. Just becuse an AOI machine works well in one appliaction does not mean in all. Plus, after sale support varies regionally. You should do your own research based on your application and region.

Do you use Orbotech?

Orbotech is a machine best bought New - If you buy used - there is an $85K (negotiable)licensing fee to use the software and get service. The machine appears to be built well, but any company who effectively cuts out the "little guy" by throttling the used market will not sell a large number of machines.

There is learning on all brands requiring fine tuning the test parameters. The first point is not to allow defects to escape. Many brands can do a good job with preventing escapes. The struggle with all the brands becomes false calls. The companies rate their machines at defects per million opportunities. When the oportuninties are calculated for a PCA and a panel as many as every 3rd panel could be rejected for a false call. It all depends on wether the work is IPC 610 class 1,2 or 3 and the density and part count of the assembly. At this shop Orbotech was the better of the machines used. We are considering using them for paste inspection as well. There is a full time engineer reviewing the inspection criteria based on defect data, including false calls and escapes detected at other operations. This work has paid off with contiuing improvements in dection and reduction in false calls. AOI is a continous improvement activity. Plan to spend a great deal of time supporting it. If the line thinks that everything is a false call the next problem is they will pass real defects after reviewing them. Without knowing the type of work and volume it would be difficult to say if this is an apporpriate solution.

There is another difficulty in comparing AOI machines. The computational power available has been growing at such a great rate it has caused large differences in performance in generations of equipment. Some of the companies were badly stunned at the start of the century and are only know getting updated machines out. The increase in computaional power has allowed more and better alogrythems which are modified based on experiance. One engineer dislikes a brand because of the enoumous support they used to require 6 years ago. There have been changes since then. You need to determine what are the requiremnts for your site. Then go looking for what might work for you.

For Trion 2340-Orbotech AOI is not so hard to handle this automated machine, specially for offline PCB test inspection, since it only used black and white color configuration. To improve its testing capability, try using the BRIGHT_A or BRIGHT_m function which differ on brightness of the shadow..unlike other aoi machines that deals with graphics interface and multicolor configuration, it is easy to make and modify the program.
