The 575 was based on the 570 machine. The 570 was Juki's first laser centered machine. It can do 0402 and ICs with a pitch of 0.65mm or greater. The 575, was a re-vamped 570 that Zevatech came up with. Juki played no part in the 575. Zevatech ad

sphericity and consistency are important. egg shaped, dog-boned shape snd tear-drops work against you and promote clogging and in-effective "transfer efficiency". One of the most signifficant factors will be brand/type. Not all fluxes are created
