Ahmen Brother! I had the unfortunate pleasure of supporting sister factories in Guadalajara and Jauarez. It is a totally different environment. I had a friend at MPM that has a great story about this shop in Mexico that kept buying the Monitor Inte

Unfortunately, IPC-D-279, IPC-TM-650, IPC-TR-464, and MIL-STD-810 will not answer your questions, because they do NOT address LF-solders. Even the tests in IPC-9701 need to be modified for LF-solders, because: * LF-solder has different creep behavior

I am looking at two different type fluxes, Kester 951nc and AIM 264-5nc. The two seem to be comparable, but the Kester is listed as an ORL0 and the AIM as a ROL0. My product builds are all military and I have been dictated to use only ROl0 flux. I kn

Hi Eric, Every mounter have a standard count and "release" off the component. The sample and cost saving way is to use the paper (e.g: 4mil,5mil...thick) to measure. Just place on the PCB with supoort base below and release the nozzle step by

Thanks Cal, I'm aware of most of what you say. It seems that the height though is routinely ignored. You say 10"-15" of leg screws, surely the difference can't be that much. All of the Asian PnP machines I have specs on are 900mm +/- for transpor
