I've been using Xilinx TQFP's in the 44 and 144 lead sizes with no trouble. I don't even bake them before reflow and have never had any problem. The Xilinx parts are certainly NOT sensitive, I could not break one with my bare hands if I tried (I ha

Desoldering often applies a LOT more heat and thermal stress to the part, and maybe mechanical forces while everything is hot, to get the part free of the board. So, a lot of damage might be done there, making post-mortem harder. Without the leads,

Sounds like Mydata might be one you could look at, for example. I don't have experience with them but they do have "smart" feeder capability. Some machines use electronically controlled and motor driven feeders, some use pneumatic and/or mechanicall

Well, it mostly does. The explanation and how-to-fix fields of the error chart do contain some howlingly bad translations. But, the how to fix field said the management info needed to be cleared. Once I understood they meant the MIS statistical dat

I'm not familiar with SPC Plus. I'll assume it's a "statical process control" system. We use the SPC data collected by our YesTech AOI system, together with a custom, web-based reporting system for process analysis and defect reporting. I am actually

Hi All! Thinking about purchasing 2nd user Panasonic p&p machines (CM88s-M1 or MSR series...) but I didn�t know anything about it�s programming. So, I wonder do I have to use any off-line software by anyway or it is possible just to load centroid dat
