Electronic　devices　play　an　extremely　important　role　in　the　aerospace　field.　Aluminum　nitride　(AlN)　is　a　promising　ceramic　material　for　high-reliability　electronic　packaging　structures　that　are　subjected　to　impact　loads　during　service.　Quasi-static　and　dynamic　flexural　tests　were　conducted　to　determine　the　rate-dependent　flexural　strengths　of　AlN　ceramics.　The　impact　response　of　the　AlN　substrates　was　investigated　using　experimental　tests　and　a　smeared　fixed-crack　numerical　model.　The　critical　velocity　of　the　impactor　and　the　failure　mode　of　the　ceramic　plate　can　be　accurately　predicted　using　the　Drucker-Prager　criterion　with　the　scaled　fracture-strength　parameter.　The　radial　cracks　on　the　ceramic　plate　upon　impact　were　well　reproduced　via　the　proposed　novel　numerical　technique,　showing　better　accuracy　compared　to　the　widely　used　Johnson-Holmquist　II　(JH-2)　model.　The　effect　of　impactor　nose　shape　and　deflection　angles　were　further　investigated　to　better　illustrate　the　low-velocity　impact　response　of　AlN　ceramic　substrates.　Based　on　the　dynamic　flexural-strength　testing　results,　this　study　achieves　the　prediction　of　low-speed　impact　response　for　AlN　ceramic　structures,　thereby　providing　technical　support　for　the　impact　reliability　analysis　of　aerospace　ceramic-packaging　devices.
