| 中文摘要: |
| 附着力低和烧结时向介质玻璃层扩散是430不锈钢发热器银浆经常出现的问题。研究了玻璃软化点、添加剂及银粉对430不锈钢发热器银浆性能的影响。结果表明，玻璃的软化点及银浆的添加物对银层的附着力和向介质玻璃层的扩散有重要影响。优化配方使用混合银粉，加入添加剂，选用合适软化点的玻璃粉，所得银浆料的印刷性能、方阻、附着力、与焊料的润湿性及耐焊性等各项指标符合要求。 |
| 英文摘要: |
| Low adhesion and diffusion to the dielectric glass layer during sintering were frequent problems in the silver slurry of 430 stainless steel heater. The effects of glass softening point, additive and silver powder on the properties of silver layer in 430 stainless steel heater were studied. It turned out the softening point of the glass and the additive of the silver slurry had important influence on the adhesion of the silver layer and the diffusion to the dielectric glass layer. Optimized formula with mixed silver powder, additives, choosing a glass powder that was suitable for softening points. The silver paste printability, sheet resistivity, adhesion, wettability and soldering resistance were all meet the requirements. |
