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. High-end SMT Reflow Machine Introduce of Reflow Soldering Oven. We often provide upgrades and rebuilds and can make specialized and custom reflow machines. Reflow Ovens - BTU, Electrovert, Heller, Vitronics Soltec Reflow Ovens for sale at. 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. And DDM is the only USA reflow oven manufacturer (that we know of). Why Buy from a Reflow Oven Manufacturer? ĭDM 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. SMT Reflow Soldering Machine 550KG Lead Free Reflow Oven Machine 5 Zones RF-5 4. Inert nitrogen atmosphere option for most models.Expert reflow application consultants to assist you.Obtain excellent reflow oven thermal uniformity with patented Horizontal Convection Air Flow Management.The current HOTFLOW series marks the benchmark - with 25 savings in total energy and 20 reduced N 2 consumption. Perform lead-free and lead reflow soldering profiles on a single reflow oven Energy efficiency with maximum soldering quality and performance Since their introduction into the market nearly 30 years ago, Ersa reflow ovens have been setting the industry standard for high-end reflow machines.Models range from benchtop solder reflow oven to batch ovens to automatic floor style systems as well as reflow soldering hot plates. There will be an 8.32 cm spacing between the boards in the oven.DDM Novastar makes many reflow ovens for the SMT market, designed with patented Horizontal Convection technology* for even heating across the entire face of the PCB. To summarize: for our 45 cm board that has a cycle time of 40 seconds, we need a 10-zone oven with a heated tunnel length of 360 cm. Let’s calculate what it will be:īS = (BL + Spacing)/CT = 1.33 cm/sec => BL+ Spacing = BS x CT => Spacing = BS x CT – BL The extra belt speed will allow for a small amount of spacing between the boards. Success! Since 1.33 cm/sec is greater than 1.1125 cm/sec, this 10-zone oven will work. How about the 10-zone oven? Let’s see if the belt speed is greater than the 1.125 cm/sec needed.īS = HTL/Time = 360 cm/270 seconds 1.33 cm/sec Now we can see that the 7-zone oven won’t do the job either. What about a 7-zone oven? Let’s calculate the belt speed for this oven.īS = HTL/Time = 250 cm/270 seconds 0.926 cm/sec The component placers will be presenting a 45 cm board every 40 seconds, so the belt speed needs to be:īS = Board Length/Cycle Time = BL/CT = 45 cm/40 sec = 1.125 cm/sec So if we choose the 5 zone oven the belt speed will be:īelt Speed = BS= Heat Tunnel Length/Time in Heated Tunnel = HTL/Time = 180 cm/270 seconds 0.66 cm/sec By studying the reflow profile in above, we see that the amount of time needed in the heated zone is about 4.5 minutes or 270 seconds. Let’s assume that you will be using a typical modern SAC solder paste. Table 1 shows some typical reflow oven metrics: Let’s make some calculations and see if your concerns are justified. But, you are concerned that a 5-zone oven may not have the capacity that is needed to keep up with the component placement machines. Your boss is pressuring you to get another 5-zone oven, as they are cheaper and take up much less space than a 7- or 10-zone oven. ![]() The boards are 45 cm long and you expect the cycle time from the component placement machines to be 40 seconds per board. ![]() You are putting in a new assembly line to assemble some large boards for which your company just received a 3-year contract.
