Since posting the above comment extolling the virtues of NSMD pads and disparaging SMD pads, we've learned that the points apply to all array devices, but in spite of that some designers of fine pitch [eg, 0.4, 0.5mm pitch] array devices choose SMD w

wich is the model of the machine you're trying to place this component? what are the placement issues that youre observing. on the IP3 that we place switches we use a 3.7 nozzle (standard) because of the dimensions on the component, the issue that I

Hi there: I'm having trouble to assign an adequate vision Type to dpak components in Fuji Flexa (placed by an IP3, SMD3 vision system). Currently we're using 254 but accuracy is reduced and also can be placed backwards (yes, I know... supplier packag

If the concern is the increased moisture absorption associated with lead-free capable materials, you probably have the most experience with phenolic materials like Isola IS410 or 370HR. The best move would be to switch to an IPC 4101/99 or /124 mate

How does one keep a pcb safe from ESD when applying an aerosol conformal coating on a flat surface? Even if you had an ESD mat to place the pcb on it would quickly be coated. The only thing I can think of is an ionizer. Does not the aerosol create a
