| 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

Les, Some of the answers to design or stencil aperture/placement machine depend upon what is the current spacing between your components which you didn't specify. Chip components such as 0402's and 0201's typically have very small reductions in pas

| | I noticed that some of our pcb's component legend/designation are unreadable as they are placed under smt pads. Is this correct and according to standard? Although we don't have any problems with them as of now, I would like to know the effects o

You might want to try going to the manufacturer about getting a refurb unit with a warranty. All of the manufacturers listed provide refurbished equipment deals that can be packaged with feeders. If you go with a broker or 3rd party rebuild hous

Now that is a BIG step. Stencil type: * A metal squeegee is fine with stepped stencils. * A rubber squeegee is fine with stepped stencils. Comments on step stencil "keepouts" are: * Use an ample space around the stepped down component pads that is

If a PCB is already going through ICT and some additional inspection method is desired to increase first pass test yield rates, what are the advantages/disadvantages of AOI vs XRay? The most common problems seen are missing or skewed components and

We reflow solder balls to the LGA using a tacky paste flux. Then we install the LGA to the PCB using a tacky paste flux. This will result in zero voiding and is a preferred method of our Military and Space clients. Be sure to read your spec sheet
