The conveyor is programmed to turn off the belts and go into an error condition after 30 seconds if the board has not passed the output sensor on the conveyor. The intent is to indicate a board jam and prevent damage to the board or belts. On convey

Hi Dave, Picture a camera mounted on top of a fixed base that pans 360 deg. back and forth. The motor connects through a circular slip ring board with brush connection. The rings are hard gold and the typical brush material is soft. Unlike the armatu

Thank you for your response. I did this: I changed the whole machine FCM and the FCM II, as you write me everything changed. Programmed new EPROM, etc. FCM machine and it works perfectly as FCM II. Only now I've changed the option to push mechanicall

Based on my experience with OMRON VT-RNS, I would not consider this machine unless you are running high volumes of a limited number of assemblies. Programming and debug took a lot more time than than other machines in the same price range. After deb

Just found from another discussion : “The Yestech (pattern match) is very easy to program and use but it took sooooo much up-keep to keep the false calls to a manageable amount. The CyberOptics (also Omron) is more of an algorithm based type of mach

We are running a CV 400 Wave solder. We are having difficulty getting sufficient flux on the boards. It uses a reciprocating spray fluxer that is controlled based on time by a board sensor located on the load side conveyor. The problem is that there

fluxer => cleaning (or lack there of) => conformal coating: there is a lack of compatibility. You need to figure-out which is the bad boy. Maybe a good guess is to conformal coat boards at each step in the process and then have them tested. Don't de

I would suggest that the pad size vs lead length vs lead pitch are helping cause issue if rest of PCB is ok From DFM , yes reducing lead length - experiement or reducing pad diameter could help. Also flux can still be issue, try fluxing part prior

Hello there, I just want to ask you how often do you take your profiles on the Reflow Oven and Wave solder? I have a HMLV line running 5-6 products per shift (Reflow Oven & WS) my tech spend too much time checking the profile, but no major difference

Hi all, We have two Heller ovens, a 1700SX and a 1700D. The 1700SX has the profiles made so when you load them the zones turn on in sequence. First zone top and bottom are on when the profile is loaded then the next (top and bot) start to turn on as
