With saving time and space. With having the possibility to change any aperture at any time. With having the chance to apply different deposits on the same assembly or the same part. A stencil printer is not for free as well and it needs consumables t

We use nanocoating also on the stencils we purchase for our facility. It's easier to clean, there is less wear on the surface, and the solder paste releases better from smaller apertures.

Hi Dale, Care should be taken when using compressed air to dry a stencil. Just as high-pressure sprays can bend delicate land mass areas between fine-pitch apertures, so can high-pressure air. In addition, OSHA frowns on the use of high-pressuer a

Hi all, We're starting up tests for pin-to-paste and, well, things could be better. We're testing different pastes and we're testing different apertures rules and, well, we're still testing. It's coming close and we're getting pretty good joint

Hi Todd, it might be a philosophical question if soldermask between finepitch pads is prefered or not. That should depend on the capabilities of a particular site and their experience. We actually prefer soldermask down to 0,4mm pitch and don�t have

Yes, you need to run the 'offsets' calibration to correct the offset issue. If the machine is in good working order and all of the other alignments and cal's are completed then you are good shape to go to run this cal. If not, you could waste a few

Dear Earl, At Smart Sonic, we have seen fiducial deterioration as a result of the epoxy not being water-safe. Unfortunately, many stencil manufacturers believe their customers are still cleaning with solvents and therefore use an epoxy that is solve

Griinder, Maybe it's me, but I think what you might be saying here is that you see a reflected image of the PCB or Stencil when you and teaching the fiducials and it is interfering with the teaching routine, is that correct? If this is true it is c

| Hi Guys, | | I am going to be graced with the good luck of processing microBGA's in the near future. A bit of a step forward from printing 20-mil pitch and wave soldering 0805's, wouldn't you say? | | So, any of you folks who have already experi
