材料测试的一个非常重要的部分是在材料成为发布产品之前找到其可用极限。有些客户喜欢在超过标准建议的 8 小时后使用球形附件助焊剂，在某些情况下这是可能的。
我喜欢使用我们的引脚传送装置来寻找球形附着助焊剂的实际极限。如果助焊剂在设备上放置的时间过长，故障的第一个迹象通常是在印刷后的相同焊盘上出现桥状助焊剂沉积。在检查引脚传送阵列时，会发现引脚与引脚之间的间隙中出现一串助焊剂。这种现象的有趣之处在于，行业内大多数滚珠附着助焊剂都有一个阈值，在该阈值之后，几乎会同时出现多个桥接。这样就更容易找到助焊剂的 "工作寿命"。
In Part 2, we outlined materials challenges that can impact robotic soldering performance. In Part 3, we shift to product solutions and emerging innovations—highlighting how cored wire performance
In Part 1, we covered how robotic soldering evolved, and why materials quality is a major driver of process stability and precision. In Part 2, we focus on common materials-related issues that can
Robotic soldering has evolved from a productivity upgrade into a precision requirement—especially as electronics become smaller, denser, and require shorter production cycles. In Part 1 of this
