Hello All, The audacity to yell Smartsonic here is appauling. This is a process approach dependent on the type of epoxy. To suggest your equipment without knowing a thing about the process is shameless. OK, now I'll get off my soap box. The low

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

| | To aid in heat dissipation of our PCB, we would like to try having copper fill areas on the board that are hot air levelled and not covered with solder resist. Then, when the board is reflowed, solder paste would be applied and then solder. Has a

You will have to forget about the idea of finding ONE algorithm to optimize SMT placement. For pick and place, collect and place, turret type "chip shooters" with moving feeder cartridge and moving board you will each have to find your own algorithm
