The invention discloses performance evaluation and test equipment for reflow soldering equipment. The equipment comprises a supporting frame, a heat capacity module, a heat insulation device and a data collector, the supporting frame is formed by combining a cover plate layer and a bottom plate layer, and the middle portion of the supporting frame is the heat capacity module bearing hollowed-out portion. The thermal insulation device is arranged at the lower part of a frame carrier of the thermal capacity module, the thermal capacity module is divided into three rows, the first row is an air module, the second row is a large-capacity module, the third row is a small-capacity module, the modules conduct heat through arranged supporting rods, and the data collector is arranged in the thermalinsulation protection device. According to the performance evaluation and test equipment for the reflow soldering equipment, the diversity and non-uniformity of reflow furnace performance test equipment are achieved, the performance of the reflow furnace can be calibrated, and the performance cannot be changed along with the width change of a carrier or multiple times of continuous tests.
Description
technical field [0001] The invention relates to the field of reflow soldering, in particular to performance evaluation and testing equipment for reflow soldering equipment. Background technique [0002] In the field of SMT hot air reflow soldering production, there is currently a lack of professional testing for the evaluation of production equipment and reflow furnace equipment, mainly reflected in the impreciseness of the test methods and the lack of uniform standards for the calibration of test fixtures, which may easily cause deviations in the test and evaluation of equipment . The performance test currently used in the industry is to deploy several temperature measurement points on the entire aluminum plate or use the PCBA board to conduct 5-30 continuous temperature tests, and calculate the CPK as an evaluation of the performance of the reflow furnace. Assess for vulnerabilities. [0003] The performance evaluation of reflow furnace equipment is currently carried out...
