Reflow Oven for Soldering of Printed Circuit Boards and RF / Microwave Housings

PRO 1600 is a forced air / nitrogen convection reflow oven with a small footprint measuring only 31" x 31" (80cm x 80cm). It has been designed for reflow soldering of even the most challenging applications including metal core, high thermal mass, RF / microwave housings, wafer boards, and ceramic assemblies. PRO 1600 is very user friendly in terms of profile creation and modification. Sealed heating chamber enables ramp up rates of up to 4° Celsius/second from ambient and programming of up to 10 profile zones. It offers a unique On-The-Fly settings adjustment capability that allows creating and optimizing profiles all in a single pass. Where other batch and conveyor ovens fail to meet the desired profile curve, PRO 1600 excels.

Precise software control delivers unsurpassed temperature uniformity. Maintaining a low delta T across all of the components on the assembly ensures that they are not overheated or thermally stressed. Even for prototypes, this often means avoiding to spend hours of testing and debugging failed boards. With the optional External Thermocouple Control (ETC), profiles may be processed based on temperature readings of the assembly, not the air temperature around it. An optional Video Recording and Observation Module allows taking high magnification images and recording video during a soldering cycle. Increased productivity, superior performance and ease of operation make the PRO 1600 a versatile system ideal for small to medium run production, prototyping, NPI, testing or curing.

Unlike a long tunnel or conveyor type SMT reflow oven, PRO 1600 does not need to be pre-heated before it is ready to process PCBs. An operator would simply turn on the power, load the control software and the system is ready for reflow soldering with the chamber at ambient temperature. This is especially helpful in non-production type environments like prototype labs or for small lot runs typically saving 30 minutes or more by eliminating preheating.

When PRO 1600 is turned on, the cover automatically opens while the loading tray slides out slowly for easy access to place down circuit boards. Once PCBs are loaded (either single or double sided), the operator would select an appropriate reflow oven profile from the software screen. A reflow oven profile is a pre-programmed set of parameters like ramp up rate, temperature, time at set temperature, cooling method, etc., that is specific to the PCBs being soldered. The software includes a library of different profiles tailored to the solder type used in the process as well as general size and mass of the circuit board. An operator can create custom profiles for their unique boards or simply optimize the existing profiles.

As the Start icon is activated, the loading tray automatically slides into the reflow chamber at an adjustable and controlled speed. A reflow profile is then processed per the programmed settings. PRO 1600’s control software constantly monitors actual ramp up rates and temperature inside an oven to the programmed values for accuracy. Once the reflow cycle is complete, the cover will open slowly and tray automatically exits from a heating chamber. PRO 1600 is now in a standby mode, ready for a new cycle run.

The following parameters may be programmed for each profile:

• Up to 5 Ramp Up stages ( ° Celsius / second)
