球化剂种类对BGA焊球质量的影响
Influence of nodulizer type on quality of BGA solder ball

摘要: 钎焊球是BGA及 μBGA等高密封装技术中凸点制作的关键材料,球化剂种类是影响钎焊球质量的关键因素.在预热温度为500℃和球化温度为280℃,球化剂分别采用机油、重油、硅油和花生油时,采用切丝重熔法制作高密封装用钎焊球.研究了不同球化剂种类对63Sn37Pb钎焊球的球形度和外观形貌的影响.结果表明,花生油作为球化剂时,63Sn37Pb钎焊球的真球度系数值最小,钎焊球越接近真球形状,球形度越好,外观形貌也最好,球化效果最好.重油、硅油次之,机油最差.Abstract: Solder ball is the key material of the bump fabrication in the BGA and μBGA high integrated package,and the nodulizer type is the main factor which affects the quality of the solder balls.The solder ball is fabricated by the fine wire cutting-remelting method when preheating temperature is 500 centidegree and spheroidization temperature is 280 centidegree,and arachis oil,silicone oil,heavy oil and engine oil are selected as nodulizers respectively.The influences of the different nodulizers on the real sphericity and the surface appearance of the 63Sn37Pb solder ball are investigated.Results show that the real sphericity value of the 63Sn37Pb solder ball is the smallest and the shape of the solder ball is more like true sphere.At the same time,the surface appearance of the solder ball is the best when the arachis oil is used as the nodulizer.The quality of solder ball is the worst when the engine oil is used as the nodulizer,and the qualities of solder balls are between them when heavy oil and silicon oil are used as the nodulizer respectively.
