UNIVERSAL SHAPE MEMORY BOARD SUPPORT SYSTEM
The existing flexible support tools are all based on pins which are contacting the bottom side of the board. With those systems the support force is applied locally and therefore, there is a risk to damage components under the joint action of the pins and the squeegee/transfer head. All those systems are also very sensitive to the contamination with solder paste or adhesive.VacuNest combines the advantages of the machined dedicated tools and of the flexible pin arrangement tools without their drawbacks. With VacuNest the support force is spread over a large surface.
A pliable antistatic chamber contains solid particles. Once the chamber is conformed with a golden board, vacuum locks the particles without shrinkage thus creating a firm and precise support for the whole batch of boards to produce.
An elastic material brings the pliable antistatic chamber back to the initial position. VacuNest is ready for another board.
VacuNest is in use on DEK, MPM and EKRA printers.
VacuNest can be adapted on printers, dispensers and pick and place equipments.
