We currently have a Universal GSM (circa 2004) GI-14 and we are approaching software limitations on multi-pitch BGAs. Any additional information about the SM421 capabilities and limitations would be appreciated.

Thu, 27 Apr 2017 15:45:00 GMT GSM2 Y-axis resonance http://www.smtnet.com/Forums/index.cfm?fuseaction=view_thread&CFApp=1&Thread_ID=18774 Any ideas that can cause y-axis resonance? I ruled out all usual the suspects (tacho sensor, driver cards, motor driver etc.). Looks like some mechanical issue, but can't figure it out. I suspect leadscrew nut - I checked it with motion diagnostics sw. and there are some positions when it does oscillate and then there are some positions when it does not. Oscillating points are regularly spaced, although not easy to "hit". Oh, btw. - it's used machine we just bought, so it did not start to occur just out of the blue... Thu, 27 Apr 2017 10:25:07 GMT Whats new in 3D AOI? http://www.smtnet.com/Forums/index.cfm?fuseaction=view_thread&CFApp=1&Thread_ID=19582 Wondering how many out there have upgraded their AOI systems to 3D technology? For those that have here are some questions I have: 1.) What system were you using previously? 2.) What systems did you evaluate in your process of selecting a new system? 3.) What system did you ultimately choose? 4.) Are you happy with the change? Also, if you did evaluate a new 3D system and decided to stay with your current system, why? There's no shortage of new 3D AOI systems out there and I've just begun the process of checking what they have to offer. I've been running a Mirtec MV-3L for several years now and I've been happy with that system but we're starting to go to smaller components so it's time to upgrade. Any information or experiences with your search for the same is greatly appreciated. M.

But 1 of them just got repaired and it needs to install the DOS windows or whatever Philip Topaz has originally. So is there anyways we can copy the DOS windows or DOS based operating system from 1 of the other 2 Topaz machines and then install it to the 3rd one? thx.

I have MY12 machine shutdown during run. Since then when I power up the machine, the TPSYS keeps rebooting, and never completing Initiate Hardware phase. I suspect that it is a hardware issue rather than software issue because I changed the hard drive but the issue exists. Can someone point me to what could potentially be wrong and how to troubleshoot it?

I have taken the picture in the attachment as my reference.I have the little stuff worked out and have it prototyped and working, but I want some outside input on the relays on the board. The relays are S2-L2-24v 4A NAIS relays. They are triggered by the microcontroller when it receives a certain input.(I take this datasheet as my reference: <a class=roll href="http://www.kynix.com/uploadfiles/pdf8827/G8VA-1A4T-R01-DC12.pdf)" target="_blank">http://www.kynix.com/uploadfiles/pdf8827/G8VA-1A4T-R01-DC12.pdf) </a> I want to make sure that I have adequate trace widths to support the relays when an auxiliary component is triggered. Right now I plan to use 1 oz copper for the board when I have it printed (trace width is 150 mil on the relays and power). I have attached the PCB design to this post. Each individual relay would have a max of 1A /30V on it, and all power lines on the board are fuse protected. In all reality, it is likely that only one relay would be on at a time. I am new to incorporating these things in to a PCB, so I may be approaching this completely wrong. Am I using the right relays? So any suggestion will greatly be appreciated!

Tue, 25 Apr 2017 18:23:42 GMT Conveyers Between SM Machines http://www.smtnet.com/Forums/index.cfm?fuseaction=view_thread&CFApp=1&Thread_ID=19561 Hi All, Looking for opinions from people on having conveyers between machines on a SM line. Im of the opinion that stand alone conveyers should be kept to a minimum. As an example of a SM line I have a Printer, SPI, 3 P&P machines, AOI, and a reflow. I'm being told to have a 1M Conveter between each machine to allow for access (breakdowns etc). My stance is the only conveyers really required is one after SPI prior to P&P and one after AOI prior to Reflow and then a Card Stacker after Reflow. This is to keep hands off during assembly. So conducting a straw poll on this what do others have? Answer gratefully received.

It freezes every time, without fail, during the initialization step (in optimizing). I don't believe there is anything wrong with the tabletop, or board program. I've transferred it to one of our other machines and it will go through the optimization fine. Wondering what I can do to avoid that annoyance.

May i know is this corrosion or pad oxidation?? This defect were found after complete of all process including cleaning and im using water-soluble flux to run the product. Im suspecting this defect may occur due to uncleaned flux.May i know what are the possibility can lead to this defect?? Is there any chances to remove the corrosion?

Thu, 20 Apr 2017 11:59:34 GMT Conformal Coating Coupons http://www.smtnet.com/Forums/index.cfm?fuseaction=view_thread&CFApp=1&Thread_ID=19556 So I'm starting up a conformal coating process from scratch (again, although it's been about 10 years) and I'm looking for the best option for verifying thickness. I plan on going the "coupon per setup" route which will encompass both our manual spray as well as automated spray operations. In the past I've used both metal and glass (lab slides) coupons, but I'm curious if there are any benefits (as well as options) with going with a coupon material that would be closer to the same surface tension as the PCB? Possibly a masked FR4 coupon? Does anyone have any experience with this? Or possible suppliers?
