FCX9M02500020Y5L 49SMD 25M 20PF 日本富士FCom晶振参数对比
测试友商的49S/24M20pF20ppm、49S/8M20pF20ppm、49S/16M20pF20ppm的参数,各5件.具体测试数据如下:随机选择FCom的相同频率,相同的标称参数测试所示.
结果发现友商的频率通常是负的.虽然友商标称±20ppm的产品精度符合标准,但一般控制在±10ppm以上,有的高达±18ppm,这对于FCom来说已经是不合格产品了.标称±20ppm的FCom产品精度一般控制在±10ppm以内.
同时友商产品的DLD2值过大.DLD2值是测试晶振在运行过程中的最大电阻值和最小电阻值之间的差值.具体反应是晶振与IC谐振时电阻值的变化,功率在0.01μW到100μW之间.如果晶振的DLD2值过大,晶振可能会在运行过程中停止振荡.例如,友商的一款产品的DLD2值达到了5.7欧姆,说明晶振的电阻值不稳定,产品的一致性不够.FCom产品的DLD2值都在1欧姆以内,比友商的产品更加一致

此外友商晶振的FDLD2值过大.FDLD2值反映了晶振与IC谐振时频率输出的稳定性.参数值越小越好.该值越小,晶振频率越稳定.FCom晶振的FDLD2值均设置在2ppm以内.
DLD2值和FDLD2较大的主要原因如下:
一.晶片材料问题,如晶片上的亮点杂质.
二.晶振厂在生产过程中对晶片的表面处理并不纯净.
三.当晶振在密封焊接时,内部有水分.

比较两个品牌使用的材料,FCom的49S晶体振荡器外壳使用二次氧化光亮外壳,在生产过程中的49S晶振检查显示其外壳采用哑光工艺.从成本角度来看,二次氧化处理的光亮外壳成本略高,但保质期更长.特别是晶振在大气环境中使用时,晶振的表面可以保持光滑,长时间不氧化,而哑光外壳更容易氧化.
从以上可以看出,FCom的产品在生产过程中使用更纯净的晶片原材料,生产工艺更先进,防止晶片在生产过程中受到水分污染.产品的一致性高于其他竞争对手的产品.此外,FCom还考虑了产品的可靠性和耐用性.此外,FCom还考虑了产品的可靠性和耐用性.它在产品外壳上使用更耐用的二次氧化工艺,以加长产品的使用寿命.
