For FR4 ENIG PCB: 1. In a normal condition, what is the broken location after BGA peeled off?(FR4 layer or Ni layer or solder ball) 2. What is the soldering acceptance criteria for BGA in CMK?

Dear Davef, Sorry for late reply! CMK is a PCB supplier, BGA solder defect were found in CMK PCB. is there other method to verify the BGA soler criteria, such as reliability test?

Good afternoon, Question is addressed to MVP 1820 AOI users. Could you give your feedback? What are the pros and cons for this machine? Ease of programming, repeatability, features etc. Thanks in advance. BR, Pavel

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

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?

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 looking into purchasing a used UP-2000 Hi-e. We are high mix /high change-over. The machines I am looking at are equipped with the grid-lok system. Can anyone give me pros's/ con's ?? Thanks in advance. Sr.

Would be my pick if I was putting a line together and was buying used. You should be paying around $35K-$40K and no more for such a machine. As far as grid-lock...........I'd probably toss that system in the garbage.
