Background technology
Growing along with electronics technology, the making increasingly complex of electronic circuit, in the production run of electronic circuit except getting rid of the mistake on R & D design, also needs to test the bearing capacity of circuit board on the other hand, because, circuit board itself exist flexural strength inadequate time, easily occur that scolding tin breaks, and then cause the damage of circuit board, but, in current existing test event, seldom there is the bearing capacity of suitable tool to circuit board to test, therefore there is certain limitation.
Utility model content
The utility model is for providing the tool that a kind of structure is simple, use the testing circuit board bearing capacity of easy to operate improvement.
The utility model is achieved through the following technical solutions:
A kind of tool of testing circuit board bearing capacity of improvement, comprise base, substrate and pressue device, circuit board under test is placed between described base and substrate, four angles of described base upper surface are respectively provided with a reference column, described reference column is provided with a step, the center of described reference column upper surface is provided with screw, four angles of described substrate are respectively provided with a through hole, four angles of described circuit board are respectively provided with a pilot hole, described pressue device is located on described substrate, and through described substrate, described pressue device is a lock-screw, described lock-screw side is provided with dwang, described dwang top is provided with idle running handle, described lock-screw upper surface is provided with directional arrow, described upper surface of base plate is provided with a circle scale around described lock-screw.
The outside surface of described dwang is provided with screw thread, and described idle running handle sleeve is connected on described dwang, and is positioned at described thread portions.
The dead in line of the axis of described through hole, the axis of pilot hole and described screw, is connected described substrate, circuit board with base with screw through described through hole, pilot hole successively by four screws.
The beneficial effect that the utility model brings is:
In the utility model, the tool of the testing circuit board bearing capacity of described improvement comprises base, substrate and pressue device, described base and substrate are for accommodating the circuit board firmly needing to test, circuit board is made to be arranged in the environment of a press perpendicular, a signal wire is extended from circuit board, this signal wire join dependency testing tool, when pressue device slowly pressurizes, circuit board produces certain bending downwards, signal wire stops transferring out information, then now, tin welding spot generation solder crack on circuit board, the reading read on now pressue device can know the maximum flexural strength of this testing circuit board, and compare with the basic numerical value of regulation, it is then qualified to be greater than, be less than then defective.And the design of described pressue device, adopt hand rotating manner, greatly simplify the work of test, complete test more efficiently.
