The resnets are "innies" as you so eloquently described :-) I'm using the laser algorithm for chip components on the Juki The resnets measure ok on the laser - same result as digital calipers... Are the "innies" causing some weird reflection with the laser when rotating the component for centering? J. ----- Original Message ----- From: Stephen R.

Sometimes there is a slight rotational error on placement, sometimes the component is out in the x axis (at 0 or 180 deg rotation) or out in the y axis (at 90 or 270 deg rotation). The machines are Juki 750 & 760 (using laser centering) Other components are centering fine... Any ideas??? Help!!! Justin Braime >> Hi Justin! I don't know if you know, but there's two types of chip resistor networks. What I call a "innie" and a "outie". The "outie" has what looks like leads for the terminations, like my ascii drawing below: _ _ _ _ _) (_) (_) (_) (_ | | |_ _ _ _ _| )_( )_( )_( )_( A "innie" has castellations for the terminations... _ _ _ _ _ | (_) (_) (_) (_) | | _ _ _ _ | |_( )_( )_( )_( )_| The "innies" you can program like a 1206, the "outies" you have to program like a leaded component, because the laser sees the body and then the "leads" off of the body... Let me know if that doesn't work... -Steve Gregory- ############################################################## TechNet Mail List provided as a free service by IPC using LISTSERV 1.8d ############################################################## To subscribe/unsubscribe, send a message to [log in to unmask] with following text in the body: To subscribe: SUBSCRIBE TECHNET <your full name> To unsubscribe: SIGNOFF TECHNET ############################################################## Please visit IPC web site (http://www.ipc.org/html/forum.htm) for additional information.
