The picture above is the feedback sent by our Bolivia customer. He bought our ST-100DW, bonding machine. This model is our best one at present. The display screen is large and it is easy to see whether the cof film is aligned or not. The two heads can work together to reduce the operation process. There is also the above camera, which can see the alignment of the PCB. If you want to perform maintenance work faster and better, choosing this model is an ideal option.
