Hi, I have a Fisnar I&J500 Selective soldering robot that has failed. I think it is from around 2000. The Fisnar I&J500 base has a soldering attachment on it. As I understand it, the base controller sends it a 5 bit command to the soldering unit. T

Hello Graham, We are currently using Tacky Gel Flux during our replacement process. We dip the BGA component on the flux prior to placement. Once it is dipped, the alignment and placement is done. As for the profile, I believe I am hitting the corr

Hello David, there are people here running these fine old machines. I have two, one I've been running for two years and another I've just acquired. It is not required to have a computer connected, but it will become handy for backing up and maintain

I understand what you are asking. I just wanted to ask if you or your company has considered purchasing an AOI or ICT? Perhaps both? Both are valuable tools in the manufacturing process. We lived without our AOIs for quite some time, but in my ca
