Sorry at the moment I do not have information but as usual I want to get some hands on sessions going. We were doing a flip chip workshop hands on session for Speedline last week in England. We did the theory and then hands on soldering and underfill

Research was done into the deflection of a totally unsupported (topside) PCB of 0.050" thickness. A dial indicator was placed on the surface and the tooling was set. The deflection ranged from 0.005" to 0.007". This is minor when you consider th

Hi ZJJ, I know exactly where you're coming from on this one! We have a similar situation here with a SiPlace 80S-15, rated at 15K max per hour. In practice, we achieve about 11K. The reason is fairly straightforward. The quoted maximum placements pe

Does anyone know of effective pick and placement optimisation tools for the Yamaha YM84 (Phillips CSM84). We are small manufacturers that have 2 YM84 machines, 1 being a triple pick machine for placing jelly beans and the other for placing IC's. We a

clarissa like in the other response if you have good technical support internally you can have good results with used equipment. We have run used chipshooters and pick and place equipment, but if we didn't have qualified personel internally to serv

Clarissa Even with a sound support team, buying used equipment is always risky. Some things to consider 1) Call the manufacturer, and make sure they still support the equipment, Parts and Technical. 2) Look at the machines with somebody who knows t

Hi Anthony I'm not sure I understand your question. Do you mean move to a better or more precise placement or to an error or bad position? I'm not aware of any calculation that can predict movement since it is based on so many factors like component
