Abstract

This paper deals with a method to insert chip components on printed circuit boards (pcb). The most known Insertion Automates are operating by setting the components serially in time. The printed circuit normally consists of simple passive chips like resistors and capacitors in his majority. Let us assume there arc 300 such parts on the board and the time applied to fetch and position the chip needs 300 mS. This will give a total insertion time of 1,5 Minutes.

CHIP PARALLEL INSERTION AUTOMAT

by Achim Hohmann and Ludwig Farnkopf

INTRODUCTION

  This paper deals with a method to insert chip components on printed circuit boards (pcb). The most known Insertion Automates are operating by setting the components serially in time. The printed circuit normally consists of simple passive chips like resistors and capacitors in his majority. Let us assume there arc 300 such parts on the board and the time applied to fetch and position the chip needs 300 mS. This will give a total insertion time of 1,5 Minutes.

  Every electronic manufacturing facility would like to minimize this time to reach a higher produc- tivity. The presented method is using one insertion step to place all chips at the same time.

STATEMENT OF THE PROBLEM AND CURRENT NEARBY TECHNOLOGIES

  The nearest known Technology is using Revolver Insertion Heads placing up to four compo- nents in parallel to a fixed distance grid. This is binding the layouter and is an additional restriction to the usable printed circuit board (pcb) space. If the components can be placed all at once one could reach a 30 times higher manufacturing flow with the above chosen assumptions compared to the serially method. This will even be increased with the num- ber of components to be inserted.

PROPOSED SOLUTION

  The principle of a technical solution is shown in Figure 1.

  The chip components are stored in rails with an aperture respective to the chip dimensions (2)....
