![]() ![]() If the oven is configured with five equal-length zones, it may be difficult to achieve good control of liquidus time. York has installed over 600 Lead Free Lines in Europe with Solder and flux systems as well as Technical Support on SMT lines and trouble shooting.įrom a practical perspective, five (heating) zones is certainly enough, given that the length of the zones is configured properly. Greg York has over thirty two years of service in Electronics industry. I recently witnessed a BOX Oven type reflow system with a profile of 27 minutes 40 seconds which gave understandably terrible results but once profiled and set correctly that produced the goods. If the oven is ineffective then it won't matter how many zones you have. Obviously some ovens are better and more efficient than others so that would be my only constraint, make sure the oven is up to it in the first place. Passives are 0603 imperial or larger.įor this board, would we see an actual difference in manufacturing process reliability between 5-zone and 8-zone ovens?Īs long as you profile correctly it shouldn't really matter as we have many users, varied in size and complexities using 5 zone ovens. Smallest components are 0.5mm pitch BGA, 0.5mm QFN and 0.65mm TQFP. Our boards are 5" x 7", components on both sides, component with largestthermal mass is inductor 10x10圆mm. We prefer to purchase a 5-zone oven as cost is lower, but are concerned that 5 zones may not be enough to ensure a reliable reflow process comparing to an 8 zone oven. Contact BTU with any questions or to learn about the latest advancements in reflow ovens, furnaces, or SMT reflow oven technology.We are a small electronics design company setting up an assembly line for small volume production. The Pyramax’s industry-leading “true” ready time allows the oven to recover and reach process stability in record time – enabling the savings without impacting productivity and throughput.īTU’s ovens and furnaces are the industry’s process and productivity leaders and have tens of thousands of installations. Next, we take on the running cost of the solder reflow oven by automatically lowering the power and process gas consumption during idle time using our EnergyPilot software. We then attack process set-up time through our innovative RecipePro software – the only reflow oven recipe generator to include convection rate in the algorithm, the most important aspect of heat transfer in a convection reflow oven. ![]() Our formula is built upon the foundation of the most reliable and repeatable/highest yield system in the industry. Pyramax reflow ovens beat the competition in thermal uniformity, repeatability and exit temperature – even at higher throughput.īTU is focused on minimizing Total Cost of Ownership for the reflow process. For semiconductor packaging, BTU offers nitrogen processing using the Pyramax convection reflow oven with astounding atmosphere purity with O2 levels as low as 2ppm above source in the peak zones. With closed loop convection control the Pyramax reflow oven offers the utmost in process repeatability, board-to-board, oven-to-oven and line-to-line. ![]() The Pyramax is known worldwide as the performance leader. In printed circuit board assembly, surface mount technology SMT reflow is performed by BTU’s Pyramax convection reflow oven. BTU’s convection reflow ovens are used for printed circuit board assembly, semiconductor packaging, and LED assembly among other applications. Typically these applications require high productivity and excellent process control.
