Pacific Trinetics Corporation's ST-600A Semi-Automatic Stack and Tack System is engineered and built to meet the demanding requirements for the assembly of today's multilayer ceramic components.
The operation begins by placing a green piece of tape, with its mylar removed,onto the LoadingStage.The Loading Stage has lines marked on the front and left corner for the operator to position the tape at the same place every time.The Stage then moves to the Alignment Station where the machine vision system automatically adjusts the X-Y and Theta to match the desired position,assuring a layer accuracy of +/- 5 microns.
Once the X-Y and Theta alignment is finalized,the transfer arm moves the tape from the Alignment Station to the Tacking Station ,where a vacuum chuck securely holds a precision build-up plate.
The Tacking Head is then lowered onto the Tacking Stage where it welds 8 points on the top layer,with 2 points positioned at each of the 4corners of the tape.The heating tip has a variable temperature control with +/- 1 ¡ætolerance.
A third camera ,which is mounted on the Tacking Head,inspects each ceramic tape placement to verify layer to layer accuracy.There is also a layer to layer offset on the stack weld to provide more uniform and consistent stacking.
Once the tacking is complete,the Tacking Head moves upward and the Transfer Arm moves back to retrieve the next layer from the Alignment Station.Upon Completion of the cycle,the Tacking Stage moves to the unload position.
