We build flex circuits by the 1000's. The fiducial quality has been trouble from day 1 and our machines don't always like to read them. We have worked out some of the kinks thru our PCB supplier but still have problems. Our PNP machines do fairly

When I enter in the program data for a particular PCB on our Juki, I choose a board fiducial and enter its X Y location as the "bad mark position". (Although I'm not sure if your model refers to this as a "bad mark" as well.) Place a sticker over tha

When leaving a job set up on pick and place machines, it is important to return any moisture sensitive devices on reels to a dry cabinet overnight to reduce the exposure time. What are some ways to identify which reels need removed? A sticker placed

Thank you all for your feedback. While the new smart reel towers are the ideal, we simply cannot afford them or better pnp equipment at this time. However for the short term, probably putting colored stickers on the reel edge folded over so it is vis

| I've heard about these reflow temperature labels/stickers but haven't seem to find them. Is there such a thing? And how reliable are they? I don't want to keep attaching thermocouple probes onto a board whenever there's a issue. | I think you are

The profile that you should be using, hopefully, is detailed in the paste data sheet. Connect your thermocouples to various parts of the board, depending on layout, population etc; and then run some trials observing the profile on your oven monitor/

| We are looking at implimenting a bar code system for a SMT | production line. To start we are looking at label printer/applicators. Are there any other companies that we should consider besides Zebra and Imtec?? Thanks for your input. | John If

I have recently been handed all responsibility of our Reflow Ovens. Upon my inspection, I discovered that any possible device on the ovens that you would think would require calibration, has a sticker indicating no calibration required. The practice

I've been reading the forum here for a few weeks and found some helpful material from talented individuals. Now, I have a question(s). I'm looking into different alternatives for doing X outs. Right now I'm familiar w/ two of them:1. Bad Board Mar
