content: Hello,I've been looking at purchasing a pick and place in the $10K range, and pretty much narrowed it down to the QiHe TVM920 or the Charmhigh CHMT560P4 after reading all the relevant threads on this forum (Thanks everyone!). However, while I was talking with the manufacturers last night, QiHe steered me toward the new TVM925, which they quoted at $6800usd.https://qihesmt.en.alibaba.com/product/60472758393-804050637/Qihe_TVM925_Good_Sale_New_Manual_Led_SMT_Pick_and_Place_Machine_chip_mounter.html?spm=a2700.icbuShop.84.4.45961d6c31ypzIThis machine is replacing the TVM920, but has only 44 feeders. It has 6 total cameras, which I assume are for speeding up viewing /adjusting parts on all 4 heads. The max pcb size is 350mmx310mm. I'm not sure what the 6th camera is for- I see 4x upward facing for nozzles, 1x downfacing for pcb alignment, but it isn't clear what the other high resolution camera is used for.Does anyone have any experience with this? I was really looking for a higher feeder count machine, and am therefore leaning toward the CHMT560P4, with 60 feeders, but the only think that turns me off is the built in screen. Though it is $1k less than the TVM925, so that is nice as well.A little about our usage- we are looking to use this for prototypes in various quantities from 3 to 300. Our main BOM has 72 total parts on it, 66 of which come in 8mm tapes. Is it feasable to run several panels with one load, change the feeders, then run another session for the remainder of parts?Thanks for your help,Neill

content: I've seen one other 6-cam machine and the 6th is a larger field of view for large packages - QFP etc.It used analogue HD cameras and presumably a capture card aimed at CCTV type applications, so not super high-res, hence needing different FOVs for larger parts.The Chinese don't seem to have figured out that you can image larger parts in multiple passes, though the extra cam probably doesn't cost much more and should be faster. Can't see it on the 925 ad above, but I'd expect it to be at the back where trays would presumably go

content: could you please upload the video to YouTube. I cannot watch it on your web site, just a lot of chinese signs on a black backgroundAnd a question:you claim for the TVM925 that it is usable for 0402. Is that really true ?For the TVM802 you also specify 0402, but the 802 cannot handle 0402.How can we trust that the TVM925 can do that?

content: 1'10" the second chip is irregular placement in IC tray.Maybe the camera needs time to fine-tuning analyzing correct angle .

If customer keep the machine running continuously, the speed would be faster.And in the latest software,We have improved the camera recognition speed.We will show in the next update of the video.

content: you probably can save a stack of cash by shopping around on the feeders. You can get 8mm CL feeders for around USD$60 or less, if you buy a machine full.The ones i've bveen using work fine with a tvm920.
