OK, did some more testing this afternoon. First, I moved the LED’s from feeder location #23 to Feeder location 30. This is three down from the other component(#33) it is picking, so it should be able to hit them both at the same time for two of the

We finally can't avoid adding wave solder to our process anymore. For lead-free, medium sized wave I'm leaning towards mid 2000s senju units as the best fit. I've never run their equipment. Opinions? As a point of reference for our general capabilit

So, got the Topaz X up and running. It has (4)FNC nozzles on 2, 4, 6, 8, and (4)74A Nozzles on 1, 3, 5, 7. We are trying to optimize it to pick up 8 components, then move over the camera, then to the PCB and place them. In the Mount data, we load

Downhole solder suggestions, in order of preference are: * Kester Sn96.3Ag3.7. Most vendors do not stock straight tin-silver alloys, whose wallet is that fat? * SAC305 can usually be used in place of one of the copper-free tin-silver alloys in downho

What solder alloy are you using at the moment which is coming to the end of its limits ? Normally in general for safe operation of an alloy we don't like to recommend any operation temp that is higher then two thirds of the solders melt point, but th

You might keep a eye on SMT auctions, Sometimes you can get a good deal. As long as you get the feeder for less than 100-200$ each at auction/ up to 500$ each for a dual lane, you can be assured that you can fix it to fully working if its broken
