The temperature field design and simulation optimization of vacuum eutectic welding equipment
The temperature uniformity of the eutectic welding equipment directly determines the quality of the electronic components,so the design of the temperature field is the key to the eutectic welding equipment.In this paper,heating component is designed,which includes heating element (infrared tubes),hot plate,baffle plate and heat shield.The method of combining the finite element simulation with test is used to discuss the configuration of two groups of heating element for the influence on thermal field temperature uniformity.The experimental results show that the heating element with variable spacing arrangement way,the uniform performance of temperature field meet the requirements of ±5 ℃.The average hole rate and shear strength of the welding electronic components reached 1.78％ and 9.8 kg,meeting the requirement of GJB 548-2005.
