Precautions for Use
z 片状电阻器的基材是氧化铝,由于和安装基板的热膨胀系数不同,在反复施加热循环等热应力时,连接部的焊缝会发生裂纹。特别是大型尺寸
W2H/W3A,由于热膨胀大,而且本身发热也大,使环境温度变动有较大反复时,载荷的ON/OFF有反复时,需要注意裂纹的发生。用环氧树脂印
刷电路板(FR-4),在使用温度范围的上、下限进行一般性的热循环试验时,1F~2E的类型不容易发生裂纹,而W2H/W3A型则有容易发生裂纹
的倾向。因热应力而发生裂纹,取决于所安装的区域的大小、焊接量、安装基板的散热性等,因此应设想到环境温度的大的变化和载荷的ON/OFF
那样的使用条件,充分注意后进行设计。
z 在RK73B1F中,由于在设备组装工序中通过静电的发生、施加,电阻器会有损伤,应注意。
z The substrate of chip resistors is alumina. Cracks may occur at the connection of solder (solder fillet portion) due to the difference of the coefficient of thermal
expansion from a mounting board when heat stress like heat cycle, etc. are repeatedly given to them. Care should be taken to the occurrence of the cracks
when the change in ambient temperature or ON/OFF of load is repeated, especially when large types of W2H/W3A which have large thermal expansion and
also self heating. By general temperature cycle test using glass-epoxy(FR-4) boards under the maximum/minimum temperatures of operating temperature
range, the crack does not occur easily in the types of 1F~2E, but the crack tends to occur in the types of W2H/W3A. The occurrence of the crack by heat
stress may be influenced by the size of a pad, solder volume, heat radiation of mounting board etc., so please pay careful attention to designing when a big
change in ambient temperature and conditions for use like ON/OFF of load can be assumed.
z Care should be taken that RK73B1F may be damaged when static electricity occurs and is applied in the equipment assembly process.
