Stand for providing integrated circuits

The invention relates to a StMadear ftia? the provision of integrated circuits and their manual removal.

Nowadays, electrical suction units are mostly manufactured by inserting the necessary components made of sand, which are o & t printed on a load-bearing plate, and the flattened components are then soldered from tape, or a soldering machine runs through which makes the necessary connections. To simplify the installation process, micro-processor-controlled systems are known / which provide the necessary components in a specific order and the location on the circuit board where a component is to be inserted / may mark a point.

Integrated semiconductor building blocks, so-called XC, are used in Sfeangenform handled, with the rods tubular with Ü-profile are designed in which the blocks are the right way round are included. Leave these rods

- 4 - Case 632

insert yourself into a stand for resting several such poles / whereby it is common that the poles are inclined to the horizontal level and the integrated modules slide out of the poles due to their gravity »

They known stands are complex in their construction and only allow a limited number of rods to be accommodated on both sides. It is therefore the object of the invention to indicate here an improvement in which »the stand in its construction is simplified and at the same time the fleasibility is significantly increased in its use.

The solution to this problem is characterized by the characterizing feil van claim t. There are further claims in the design of the Wti indsaf .aa * The stand given there for the provision of integrated holding circles is, in its design, and due to the interchangeable set of fleatiöel. Its capacity to accommodate packaging stems is considerably larger than that of the well-equipped stands.
