Hi All,

We are investigating post reflow AOI equipment. Have already got Yestech machines but not sure whether to continue along that line. Does anyone have any comments (good or bad) on other manufacturers

Saaitk,

We are currently running 5 Mirtec machines and have had great luck with them. I am not familiar with Yestech but I've heard they're similar.

Good Luck

CL

You should check out Modus. If in the US, ERSA is the distributor.

Saaitk,

Are you in a high mix/low volume or low mix enviroment?

What are you looking for the system to do?

What are the current issues you are having with your system?

What is it about YesTech you don't like?

We don't really have any issues with Yestech, but have been instructed from higher up to investigate different models. We will be running med to high volumes and need to be able to keep up with our SMT throughput.

WE ARE RUNNING A VERY HIGH MIX OF PRODUCT. WE ARE RUNNING THE AUGUST NSX-105 AND THE CAMTEK FALCON. I HIGHLY RECOMMEND THE CAMTEK FALCON.

The YesTech machine is an exceptional machine for the price. You may be able to find other machines with similar performance, maybe even at similar cost but if you are having no issues with them why go through the cost of putting in a new software platform? If you need to balance your production across machines you will need to do all new programs. I would stick with what you have and maybe have your higher ups write and debug a few hundred AOI programs and give them an idea of what its like!

Good idea Cmiller, would probably have to explain to them what AOI is first :)

Cmiller is correct are not going to find a better machine for the price. Also I have used several different AOI platforms and the Yestech is hands down the easiest to program. Keep in mind that changing platforms is expensive. Operators, programmers, maintenance have to be trained on multiple platforms. Also your operators will always be complaining that they want to use the Yestech AOI because it has less false calls. The Yestech machines can be networked so you only need one part library and program.

I have experience programming and using the yestech system in a high volume high mix environment. The system seemed to work well until I used a more sophisticated system. When I changed jobs and had another opportunity to spec. in paste and post-reflow AOI. I looked at everything very closely I decided on Orbotech. The Orbotech post-reflow AOI system is a true 3D system that gives you the ability to inspect solder joints more throe. The programming of the system is a breeze with the ability to edit wile the machine is running, kick off your changes and have the system automatically use your changes on the next board.

If I could only buy one AOI system I would go with the Paste machine that has brought our quality to new levels. Last month with our highest volume product we were at 1500 PPM based on actual PPM not DPMO.

Hello Saaitk,

I was recently tasked with selecting an AOI system for our company. We are a low to medium manufacturer as well. I looked at several different vendors and narrowed the field to Mirtec and Yestech.

I found that the programming was very similar between the two machines. Personally I thought that the Mirtec software was more comprehensive. But the main reason why I selected Mirtec was the fact that the machine provided better defect coverage than the competitive system, especially with regard to solder inspection. I also ran a very simple Gage R&R test on the two systems. The Mirtec machine easily won.

Although I was less concerned with throughput, the Mirtec machine was about two and a half times faster with about 20% less false calls. This did help with my ROI, but as I mentioned before, defect coverage was my real hot button.

I agree that changing platforms is never an easy process, but if your current platform doesn't meet your requirements, you may want to cut bait! It really comes down to dollars and SENSE...

Good luck Saaitk.
