Hi Gerard,

Yes, this is the path we are on. I first found out the tool was not available 
and the brand was purchased by another company. Mike suggested McMaster 
57805A44, which I bought and tried. It is indeed convenient to unplug the 
connectors. So it will be useful for module installation. But one problem for 
using it during the module production is that the module is placed in the 
storage box, and the tool is too long to fit in, as shown in Shenghui’s 
photo. I have ordered 5449A52, which is shorter by 2 inches. Will see how it 
works on Monday. 

Zhenyu
