BTU
Pyramax 125A
The BTU Pyramax 125A is a reflow oven for SMT production. The BTU Pyramax 125A has 10 heated zones. The BTU Pyramax 125A has a maximum temperature of 350°C.[1][2][3][4]
What it is
The BTU Pyramax 125A has ten heated zones, each with top and bottom heating elements. The maximum operating temperature is 350 degrees Celsius. The total length of the oven is 5,844 millimeters, with a heating length of 3,175 millimeters and a cooling length of 1,219 millimeters. The oven operates in an air atmosphere. Power requirements are 480 VAC, three-phase, with a power rating of 93 kVA. The conveyor system supports both mesh belt and edge rail configurations.[1][2][3][5][4]
How it works
The oven features closed-loop convection control that maintains stable heat transfer across the board. The control system is the WINCON software platform, which provides profile management and data logging. The heating and cooling rates are programmable. The clamshell design of the process chamber allows access for maintenance.[2][3][4]
Where it fits in the process flow
General reference — not yet source-verifiedThe BTU Pyramax 125A is placed in the SMT assembly line after the pick-and-place machine, where components have been placed on solder paste printed onto a printed circuit board. After reflow soldering, the boards typically proceed to inspection stations such as automated optical inspection (AOI) or X-ray inspection.
