CNSMT is a leading supply company in Shenzhen China when it comes to SMT line of products and equipment, including the Heller Reflow Oven.


The Reflow Oven is a machine that makes sure that all of the needed components are well placed on the PCBs to ensure quality and efficient performance.


How does it work in actual?

If you are dealing with an SMT Line of production, you should be working on tons of circuit boards that are composed of hundreds to thousands of tiny components to be part of an overall mechanism. Making sure that those hundreds to thousands of tiny components stick to the board, soldering is done inside the reflow oven.


  • Preheat your oven.
  • Insert your board.
  • Set the machine well with the proper parameters for a sure and 100% concise work.
  • Adjust your temperature and let the board stay there for 1-2 minutes.
  • Take out the board and let it cool for a while.

What are the benefits of a Heller Reflow Oven?


  1. Increased Production – working with a fast, efficient machine like the Heller Reflow Oven can yield more, thus increasing the production’s output.
  2. Low maintenance – most Heller Reflow Ovens especially the newer models are equipped with maintenance free technology that helps the operators in maintaining the machine even after multiple use. For example, most Heller Reflow Ovens are equipped with cooling technology, which is helpful when saving on energy loss, but also eliminating the risk of overheating that can damage the machine overtime.
  3. Less Nitrogen use – Nitrogen gas is used in order to keep the soldering process in order to prevent oxidation. The more Nitrogen gas that you use, the more expense you need to do a cycle of soldering. But with most Heller Reflow Ovens, less Nitrogen gas is used, thus making it very economical and good to the environment as well.
  4. Void free – where you can do inline reflow with vacuum furnace.
  5. Industry 4.0 compatible – which means that your machine adheres to the current trends and advancements when it comes to reflow oven.
  6. Equipped with the Cpk software at no charge – ensures the operators with full and fast management of the soldering process.


What does the Cpk software do?


  • With fully integrated Cpk software, the program will watch over the process for you, making sure that everything is running smoothly.
  • It provides temperature monitoring on heated zones.
  • It can generate a complete report of all parameters and calculations used in the process.
  • It can be programmed to send the report directly to your operator’s email, for faster information.
  • It is completely user friendly, giving you the best user experience.
  • It works accurate and fast, which gives you the advantage of a faster production, for more yields.


This is just a brief summary of what the Cpk software can do. There is more to like about this software, and CNSMT is ready to let you know about its capabilities once you place an order with us.
