DEVICE FOR ELECTRONIC PRINTED CIRCUIT BOARDS MECHANICAL TESTING Russian patent published in 2015 - IPC G01M7/00 H01L21/66 

FIELD: testing equipment.

SUBSTANCE: invention relates to the testing equipment used during strength testing (in particular strength testing of electronic PCBs during manufacturing). Device contains power framework including fasteners for electronic PCB installation and support poles on which the pressing mechanism, metering probe and indicator are secured. The power frameworks is made out of four support poles connected by rods along the perimeter, at that to two opposite rods cross-bars are secured with installed fasteners for electronic PCBs with possibility of PCBs movement along the parallel rods and cross-bars. Above PCB of the support poles a conductor is installed made out of the ring with top and bottom meshes, in mesh cells indentors are installed till rest against PCB surface. Above the conductor in the support poles the press mechanism is installed, it contains crosspiece with plate, and metering probe and indicator are secured in the suspended assembly on the cross-bars under PCB. Number of points for the indentors installation is determined as per equations.

EFFECT: designing of simple loading device for mechanical testing of the electronic PCBs.
