Reflow Ovens




Horizontal Convection Air Flow
*Patent # 6,936,793

DDM Novastar makes a revolutionary reflow oven for the SMT market, designed with patented Horizontal Convection technology* for even heating across the entire face of the PCB. Models range from a traditional benchtop solder reflow oven to batch ovens to automatic floor style systems. Also selections for reflow soldering using hot plates and vapor phase ovens are located here.

  • Perform lead-free and lead reflow soldering profiles on a single reflow oven
  • Obtain excellent reflow oven thermal uniformity with patented Horizontal Convection Air Flow Management
  • Expert reflow application consultants to assist you
  • Inert nitrogen atmosphere option for most models

Why Buy from a Reflow Oven Manufacturer?

DDM Novastar is perhaps the top worldwide reflow oven manufacturer for low to medium-volume reflow systems and one of the top companies manufacturing higher volume systems.   And DDM is the only USA reflow oven manufacturer (that we know of).  When you buy from a manufacturer like DDM you get a reliable source for Spare Parts, Repairs, and Upgrades: DDM is still producing parts for our reflow systems made 30 years ago.  We often provide upgrades and rebuilds and can make specialized reflow machines.  Whether you buy a reflow oven made by DDM from us or one of our local representatives you know you can depend on service and support.

Also, visitors should see the DDM article on how to buy a Reflow oven as published in SMT magazine’s June 2015 Issue:    The beginning paragraphs here:

Selecting a Reflow Oven, Part 1

How many zones can you afford?
Seems like an odd way to start a discussion about Reflow Ovens, but it’s not entirely unreasonable. As with any complex process, there will be tradeoffs between cost and capabilities, and more zones will always give you more flexibility and better predictable quality, but at a cost. The decision has to be qualified primarily on your anticipated throughput, that is, how many boards you process in a day or a week.
There are other considerations too, such as board size, component density, and appropriate thermal technology, but we’ll talk about those (and more) after identifying the work flow volume. Following is a guideline for zones relating to typical volume needs:

Board throughput Type/Zones Typical cost range
1-5 boards/day Single or dual hot plate; no zones $1,000 - $2,000
12-15 boards/day Batch oven, single zone $2,500 - $6,000
100 boards/day Conveyorized 3-zone oven $10,000 - $15,000
Over 100 boards/day No. of zones dependent on
speed & volume
Up to $200,000


Now for the explanation. Every soldering operation requires a preheat stage for a certain period of time to activate the solution, a soak stage for a different period of time, and a reflow stage where temperatures peak for yet a different time frame. After this, the board is removed and cooled. Depending on the material, e.g., lead, lead-free or specialty materials such as epoxies, the heating profile for each stage will vary according to the manufacturer’s specifications to achieve optimal bonding.
