The same with Russ, I would look at Vitronics and BTU. based on my experience they give best results especially on the profile. Maintenace is also superb! BTU has modular blower, heater T/C assy. Vitronics is "XPM - NO PM System" Now, BTU offers lif

Hi there - unfortunately, there are no good cleanliness specs available mainly because clealiness requirements are case sensitive - you should talk to Terry Munson at 765-457-8095 - he can definitely give you advice on Ion Chromatography, SIR, ROSE t

Based on X-ray imaging, IPC-7095 standard specifies three categories for void size for BGA solder joints. These categories are based on the percentage of joint cross sectional area occupied by the voided area. Class III Small: Void area is LT 9% Cla
