content: Just put up a quick tour of our pick and place line.https://youtube.com/shorts/k3VpMXQpQUAThis is after we've added in the SPI and AOI and before we've got the corner unit in, so we're a bit limited for maximum length.MPM printer, UIC pnp, cyberoptics SPI and AOI, essemtec oven, nutek and fuji board handling.

content: Cool! And I see Jo's also usingcordless antistatic like LCSC.So this is actually your in-house line? Were you using an Australian CM before? Why aren't you crowing louder about your effects being made in Australia, because this is quite unusual and is surely a selling point!

content: Esd wise were actually very careful, we are wearing ESD boots from Elten, attached to flooring from Desco and we've got wrist straps that we attach when we're actually opening parts. These are connectors though so aren't esd sensitive.

content: I got distracted and missed the other questions, this is our in house line, in our factory. We haven't used an Australian CM before. I think country of origin is the least interesting thing about our product line but also might be bad for sales as our main competitors are often made in the our main markets, the USA and EU.We also have a full metal working line and upstairs is assembly. We're trying to get heavily robotised as our wages are so much higher than our competitors in the mid west USA. We've only got 5 staff.

content: Hey that's really cool to see your setup!A couple of questions for you:- Where do you get your info on configuring the line? EG, your AOI is before the oven - how did you come to this decision? At a first guess, I would have placed it after the oven to catch any tombstones, etc. But before the oven makes sense too as you can fix any misplacements before they are soldered down.- If your SPI finds a problem with the paste, what do you do? Pull the board and clean it? How do you clean it?- Has adding the SPI and AOI increased your yields? Are you willing to share what they were before and after?- What do you do about dust?So many questions....Good luck and thanks for the video! I'd love to see more.

They come on 10m long rolls and I got a pallet of those. I think from SCS or Desco. I got them shipped from the USA as it was cheaper than local options. Local epoxy floor was pretty pricey and we had to be out for a while. Upstairs all has flooring that's similar to the benches, downstairs has squishier ones where you're walking. Copper tape grid under everything. The metal working side of the factory doesn't have the same flooring at the moment for most of it but I've got enough rolls left to do it.Quote from: law on December 27, 2024, 12:55:24 amWe tried a few layouts. The AOI before the oven is because there's one annoying connector that I was worried about placement of. We basically never have issues with tombstones, if we did it's from paste or placement errors so they are captured anyway. If the paste is good and the placement is good, the soldering is good in my experience so far. My oven is problem free. The AOI just makes me less worried about unattended running, or a reel having parts in a different orientation or something like that. I don't want to make 1000 units and then have to rework all of them or something like that. I'm still improving the use of the SPI, it's not currently connected up to the printer to feedback info to change the printing behaviour. We clean the boards by wiping them by hand with the same cleaning chemicals we use under stencil in the machine, then putting them in the ultrasonic cleaner we also use for the stencils. I'm a bit unsure currently how tight deviation in average volume etc should be. I should look up the IPC standard for that as I just used the defaults...SPI and AOI has increased yield, but more significant it reduced worry. Plus the 3D SPI is fun, it's magic the detail it can get.
