Case details
Characteristics of military aerospace products and the reflow welding process requirements:
Due to its special requirements and application, the welding process and conventional welding process of military PCB is very different than others, require the solder joint to be more reliable, and more durable, BGA components welding quality to be more solid, and for multi-layer PCB products welding.
Because of the particularity of military products, there are high requirements for hot air volume control, cooling air volume control, hot air temperature uniformity, nitrogen protection, uniformity of oxygen content in the furnace and so on, during the welding.
Reflow welding equipment solution:
Military industry products have below characteristics, big size, multilayer, the size of the component differentiation is bigger, high heat absorption, so it is important to control the reflow soldering temperature uniformity, nitrogen protection, oxygen content, etc; otherwise it may cause some solder joints virtual welding, black surface, as well as the welding is not firm, which will not meet the welding process requirements.
Suneast Technology reflow oven has the following advantages for the welding of military and aerospace industry:
1. Independent temperature control for sections, separate frequency converter control, which will effectively control the hot air volume in each section of the temperature zone, to ensure the temperature uniformity.
2. The whole process is filled with nitrogen, and nitrogen is independently adjusted in each temperature zone to ensure uniform and reliable nitrogen in the furnace.
3, Multiple cooling zones, with independent frequency converter control, which will effective control the cooling slope.
4. New flux recovery system ensures flux recovery more thoroughly, keeps the furnace clean, saves maintenance time and reduces use cost.
5. The key control components are imported brands.
