For the customer … WebCurrently, the main method for reflow profile prediction is try and error, which requires that the operator has a wealth of experience [2]. Since the reflow process has a certain randomness which is affected by various uncertainties and the environment, it is necessary for reflow profile setting and analysis from the perspective of reliability. pearl 16th birthday cake
