| | | I was wondering what measurements are used to define pitch? | | | | | Frank: John's correct with the most common definition, but there can be others, depending on your perspective. TTYL Dave F | | | | Pitch. The center-to-center spacing between the (1) leads of a component, (2) pockets on a carrier tape, or (3) two adjacent sprocket holes. (4) The nominal distance between the centers of adjacent features or traces on any layer of a printed circuit board. | | | | | Thanks for the clarification! So in generic settings what are the normally the components with the smallest pitch? Will a machine with 20 mil capability handle almost anything? | Frank:
1 For non-array components; the more complicated the function of the compoent, the more likely it will have a finer pitch than a component that is less complex. So I'd expect a TSOPs and a 208 lead QFPs to have finer pitch than a resistor array. If that is't too generic. 2 Machines that can handle 20 pitch can usually handle the more coarse pitches.
