This looks very interesting, but I can't find any videos of it placing midsized ICs. How does it do with, say, TQFP or SOIC parts? Do you have to manually align them in the trays each time, or does it have a camera for that?Personally I've had some good experience with the TM220A from Neoden, it supports 8mm, 12mm and 16mm reels, a tray for ICs and larger parts, and 2 nozzles which can be easily replaced. If your budget allows it, I would highly recommend it!
Low cost machines won't be able to place 0402 or 0201 adequately due to the lack of vision correction, but that is also not what these machines are designed for. Unless you're going really high density or parasitic capacitance/inductance plays a role such as RF, it's very easy to avoid them.hardware_guy said:First you need to decide, how many reels you need in the machine at the same time. And, do you need 0402 and 0201.
That TM220, has something like 20 reels, this is useless. As someone said, it is "toygrade".
Another interesting source is actually the demo models of equipment manufacturers themselves. These are usually on display for a few months at the manufacturer to show potential customers the possibilities of their products, but the machines obviously don't accumulate many "hours" since they're only occasionally turned on. When they're out of assortment, they're sold off at half the price.As ArticCynda says - older machines will not be able to place the smaller components correctly - this is probably why they appear on the 2nd hand market - because companies upgrade their equipment.
