Hello sir, Limits in SPI can vary a lot, also depending on finishing of the pcb. For example 170% volume on an IC (assuming is fine pitch) can be okay for ENIG, but very bad if HASL. For are I would recommend that you use either 50-130, or 60-135 max

Hi, We're having issues with our mydata tp9 pick'n place. It doesn't go all the way down on the tool, so it can't pick it up or install it. The fault code I get when trying to install tools is F-TLMN-18: Can't reach tool bank. Any ideas? I've comp

There is no industry standard for BTC stand-off height. "IPC-7093A Design and Assembly Process Implementation for Bottom Termination SMT (BTC) Components" just finished "Final Draft for Industry Review" in December 2018. It mentions stand-off height

I don't think that there is an industry standard on that. Each machine manufacturer will have to say what they mean. I think the first option looks at what you taught and then looks at what it sees when looking for the fiducial. The other method sou

You may find some wetting issues running LF HASL with 63/37, as your reflow temperatures will be significantly below the LF reflow. On fiducials...if you don't have a quote for your boards with ENIG, I would recommend at least checking it out. It's

Hello We have a GSM machine with two heads from the universal company, currently the machine fails to zero and in production mode, when the heads increase the displacement speed in the Y axis, they stop immediately. And the error illustrated in the i

Yes, we can't use pure Pb PROCESS. And as I say we will not use it anyway, as we have lead-free BGA's, LGAs, component with Solder Charged Terminations... It's became almost normal practice to solder it with leaded solder pastes. In this case peak re

Hi Daisy, I have worked with Viscom AOI before, I am in training with Omron now, but there were many times when this happened to me in the past. Recommended things to do: - Check for duplicated analysis - the AOI might spend time with taking pictur
