Provided is a pentaaryldiamine-containing bismaleimide compound of Formula (I): wherein Arto Arare independently C-Caryl; and Arand Arare optionally substituted by one or more substitutent(s) selected from the group consisting of C-Calkyl, C-Calkoxy, and cyano. The compound of Formula (I) is obtained by a method including the steps of reacting a diamine with maleic anhydride in a solvent to form an amic acid, and cyclodehydrating the amic acid in the presence of a catalyst and a dehydrating agent. The compound of Formula (I) has a nonlinear and asymmetric structure, is amorphous, and is readily soluble in a variety of organic solvents so that the toughness of the product made there from can be improved and processing of the compound can be simplified.

Pentaaryldiamine-containing bismaleimide compound and method of producing the compound

Disclosed in an apparatus for measuring positively-sensed force of an electrical connector, comprising: a base plate; at least one L-shaped pads, the two L-shaped pads being each affixed to the base plate at an upper end thereof in such an arrangement that ends thereof oppose each other; an elastically deformable sheet provided between the two L-shaped pads, the elastically deformable sheet being affixed to the base plate and formed with a projective measuring region at end thereof; and at least one strain gauge inertly affixed to the elastically deformable sheet, the strain gauge beingconnected to a signal transmitting device that outputs strain value of the strain gauge to a signal amplifying device for display purpose in response to deformation of the elastically deformable sheet. While implementing this invention in measuring positively-sensed clamping force of terminals of an electrical connector, bottom ends of the two L-shaped pads and the projective measuring region of the elastically deformable sheet are inserted between the connector terminals. Since the two L-shaped pads each have a thickness being equal to a thickness of a circuit board into which terminals are inserted and accommodating width of the connector terminals, and since the circuit board has a thickness being less than the thickness of the two L-shaped pads and a transverse gap formed between the connector terminals, the elastically deformable sheet is thus deformed while experiencing lateral pressure exerted by the connector terminals. Strain of the deformed sheet is thus measured by the strain gauges provided thereon. Strain signals are transmitted to the signal amplifying device through the signal transmitting device to acquire the positively-sensed clamping force of the connector terminals effected to the circuit board.
