183C, 60 +- 15 seconds). The quesiton to use a straight ramp or soak profile comes down to the product your are soldering. The key is to get the whole assembly at the same peak temp (minimized delta) and same TAL for effective formation of the so

I do agree with Mike, if you are looking to purchase a board wash system, do not get a dish washer unit, purchase a system built to wash PCB's not dishes. We had them at the former company I worked at and they worked best. They moved everything to Ch

YV100, easy... YV112 uses a dual work-area, dual gantry machine in which the gantry does X and the PCB-table does Y movements. Also each gantry can only work on one PCB work-area and can pick form only one side of the machine. Basically you have two
