Greetings. Does anyone know of a good reference on the proper physical handling of surface mount devices? We have a number of very small builds, so our stockroom is very often issuing single piece quantities. The parts are protected from ESD, but

If you are sure that your part data is correct, have you checked the calibration of Z origin? Are the parts leaving an impression on the paste or is there no indication of an attempted place. How small of resistors are we talking 0402, 0603, 0805?

You also should check to make sure you have blow off at the placing station set properly. I have seen machines with the flow control valve shut completely off not release parts properly. The parts end up in the scrap bin and the machine thinks they

hi guys the scenario is: when placing parts which required maximum speed, the cp6 sometimes missing resistors here and there, when checking part data, everything ok i notice that when the machine switching between high and low transport speed, (eg: r

Hi Better to check the table calibration and wedges also the rack and pinion gear at the back of the table for control if you go into mechacheck you can set the servo and the calibration data if its an early cp6 its quite simple to set up if its a cp

Another thing to keep in mind are the vacuum hoses. The early models had a real problem with the vacuum hoses that connect to the back of the windmill. They would crack or wear through due to rubbing and cause a loss of vacuum which could cause your

Theres something to be said for having a machine operator or inspection person carry the board from the output to the oven. Id say about 1/2 of our issues are fixed/noticed in this simple step of transferring the board from the PNP to the oven. If

Your typical high mix line would consist of, Stencil printer, 1-2 foot conveyor belt, fast PNP machine (say a universal 30 spindle turret lightning head), 1-2 foot conveyor belt, large/heavy part PNP (say a universal flex jet 7 spindle or 4 Spindle),
