prevent element warping are as follows:
1. Choose welding materials with strong adhesive force. The printing accuracy of welding materials and the mounting accuracy of components also need to be improved.
2. External electrodes of components shall have good wetting stability.Recommended: temperature below 400C, humidity below 70%RH, the use of components into the factory should not exceed 6 months.
3. Adopt small welding zone width dimension to reduce the surface tension on the end of components when solder melts.In addition, the printing thickness of solder can be appropriately reduced, such as 100um.
4. Welding temperature management condition setting is also a factor for component warping.The general goal is to make the heating uniform, especially before the welding fillets at the two ends of the element are formed.

What are the advantages of reflow soldering?
(1) the reflow welding technology does not need to immerse the printed circuit board into the molten solder, but USES local heating to complete the welding task;Therefore, the components that are welded are subjected to small thermal shock and will not be damaged by overheating.
(2) in the welding technology, only solder is needed to be placed in the welding site and local heating is required to complete the welding, so welding defects such as bridge are avoided.
(3) in reflow welding technology, the solder is only used for secondary purposes, and there is no re-use. Therefore, the solder is very clean and free of impurities, ensuring the quality of the solder joint.
