Hi guys, I'm a newbie for SMT field. Currently, I'm facing a problem that there were many defects such as tombstone, missing, skewed, billboarding that happened with 1 type component (Resistor 0201) with a specific supplier X (we have many supplier b

We have an assembly which we are trying to machine pick and place a Mil-Max pin that is .020 dia placed in a .026 hole. The board is .1125 thick. We have to place 106 of these pins. Without going into the challenge of getting proper hole-fill to me

Hi Reckless, No, I don't think it's a $1K job, just for the hours needed. You still need to learn the absolute basics, such as navigating the menus, creating a program, nozzle changing, identifying parts with the laser and camera, Pick timers, z hei

I dont know what kind of feeders your using for 0402 but it matters. It must be repeatable. It also sounds like your feeder z height is wrong. Test pick on the feeder and change the z until it just starts to pick it up and your z will be set. One oth

Hi, I think the comment about the board height is because the MYDATA checks the board height each time it loads a tool so this is eliminated from being an issue because the machine knows the PCB height. I don't think it's so much what height the PCB

99.70% mounting rates. 4.Make sure your machine can handle the recognition of this components (shape & height) usually height measuring(pick up error) is the biggest problem with resistors. 5.When mounting a real PCB you can have spacings up to 0.3mm

The CSM84 family units are 3 headed pick & place machines with mechanical chuck centering technology. They use a beam pointer for fiducial correction. The CSM84V is the same as the CSM84 but has a downward looking fiducial camera onboard in lieu of

Hi larry, don't know if you resolved your problem but if machine is picking part three times, rejecting all three but places number fourth your nozzle pickup is misaligned very slightly. During the first three pickups the nozzle is finally seating it
