SPM is superior in terms of technology and application. SPM has larger print area, up to 20� x 19", vs. 17.7� x 15.7� for the MicroFlex. MicroFlex is microprocessor controlled while the SPM has a PC. SPM can print down to 12mil (0.3mm) fine pitch no

The root cause is dependant on the type of solder "splash", ball, whatever, that you are seeing post reflow. If it is smears, then cleaning the stencil underside is probably the answer. Are you using automatic wipers? How many print cycles between w

shawn, define what you mean by solder ball's scattered across the board? I'd tend to agree with the thoughts of too much paste on chip's but normally your ball's would be mainly around these devices although som can move around depending on the surf
