It would be interesting to see how those machines work. But then those won't be cheap too.

post the website or search term you used to find this SPI/ AOI machine. I've never heard of such a thing. Is is pre-reflow AOI or post-reflow?

1. The jetting head flies very low to the level of the board. So, performing AOI function will crash the head. 2. AOI is performed close to the end of the line, after P&P or reflow. Are you planning to run the boards back-and-forth, on the line? 3. L

Hi Grant, The purpose for allowing the solder paste to reach room temp before production is to reduce the amount of water absobtion from the air. (e.g. a cold glass of water "sweats" on a humid day)The purpose for mixing is to make the viscosity more

Hi, I wondered how people warmed up solder paste at the start of the days production. I saw some paste mixers at a show, but only saw ones that mixed small solder paste tubs, not tubes. Can you get mixers that handle tubes. They said these mixers a

OK. Thanks!! Lastly, is it the nature of the chemistry that Sn/Pb solder mixed with Pb-free alloy will be getting voids? If so, what's the physic/chemistry behind it?

All I got to say is a bowl and spoon and mix it up a little before u place it on the stencil. That works fine on our end all the time.

FYI AIM has a patnented in-tube mixing propeller. Crazy, but it actually works.

How have you created the oven profile? Have you taken into account the heat soak from the components/board/carrier etc. Is the paste being mixed correctly before use, is the paste in its use by date & at ambient temp etc? I thought almost all the
