We present millimeter imaging observations of a B5.6 flare which occured on 1994 August 16 in the active region AR 7765. The BIMA interferometer and the Nobeyama radioheliograph observed both the impulsive phase and the thermal phase of the flare emission. The 3.5 mm maps obtained with BIMA allowed us to determine the location of the radio source and its properties at different phases of the flare evolution. In X-ray wavelengths the impulsive phase was detected by the first two channels of BATSE (25-50 keV, 50-100 keV); although YOHKOH/SXT did not observe the impulsive phase, it was possible to image the post-flare loop in soft X-rays. We compare the images of the flare at different wavelengths and discuss the relevance of millimeter emission in the context of flare models.
