Please clarify, Z axis gears (Blades)? The MPM head I believe is what your are asking is driven up and down via a lead screw. The machine gets the zero point from the "HAT" tactile sensor in the table nest. When squegees are installed the blades are

By "placement pressure" I assume you mean force. I don't know of placement machines that have transducers mounted on the placement spindles that actually measure force. We made a board with a force sensor mounted through a hole so that it was the sa

Start with a load cell (force sensor), you will need one that can handle the force range you will be placing. Someone please correct me on this if I'm wrong but I seem to recall that placement force runs in the range of a couple hundred grams. Chec

| Here is a good one for ya. Our IP3's MTU will not pick QFP240's out of cavities, 10, 12, 13, 15. This is a 3X8 tray. The listed cavities are also the closed cavities that are used for tray eject. There is plenty of vaccum, the nozzle comes down

I'm not personally familiar with the 265 but it sounds like the machine's board stop actuator is not retracting or a sensor that detects that actuator position is stuck (probably a reed switch.) If your stop is not retracted, then the sensor is telli

Hi, Noticed that MPN--MAL215099913E3 used in one of our assembly with 22mm component height. In General 15mm height is right to set height calibration (98 % of the parts will be covered with this height dimensions except specific Connectors, Transfor

This problem happens when a dark part is placed where the main conveyer stop sensor is located.The machine does a board check ( back to loading pos ) . If a part is under the sensor it absorbs the beam and the machine thinks there�s no board. The ta

Can you describe the failure mode of the soldering defect, i.e., is it failing to meet the height requirement for a castellated termination due to not wetting of the component terminations, or not wetting the pads sufficiently, or....? We install a
