【 JJY 】 How to Choose the Right LED Solder paste?

WithLEDThe rapid development of the industry has led to its wide application in the marketSolder pasteThere are more and more types. Different alloy compositions, different formula ratios, and different manufacturers have left us dazzled and overwhelmed. So how to choose the right oneLEDWhere is the solder paste? Next, JJY Solder Paste Manufacturer will answer this question for everyone:

In the pastLEDThe most widely used solder paste in the industry is low-temperature lead-free solder paste4258BecauseLEDThe LED beads cannot withstand high temperatures and can only be processed at low temperatures, which also leads toLEDThe products are rather brittle and the quality varies greatly.

WithLEDThe development of technologyLEDThe quality of the lamp beads has been greatly improved. When welding, a melting point of can be adopted183℃Lead-free solder paste, commonly known as medium-temperature solder paste, has an alloy ofSn64Bi35Ag1.0This type of product containsBiThe low-melting-point lead-free solder paste, with the addition of silver, has changed the mechanical strength of the solder joints of the tin alloy. Significantly improve the reliability of solder joints and be suitable for the mounting and through-hole processes of high-frequency tuner series products.PCBProducts such as boards and electronic components that cannot withstand high temperatures have a very high welding capacity, with bright and full weld points.

WithLEDThe expansion of the application scope of the product, someLEDOutdoor large products have relatively strict requirements, such asLEDDisplay screenLEDAdvertising lights and the like often have to endure sun exposure and rain. This requiresLEDWhen components can withstand relatively harsh operating environments, we should appropriately choose high-temperature lead-free solder paste. Compared with medium-temperature solder paste, it has better stability because high-temperature solder paste has three alloy component ratios, namelySn99Ag0.3Cu0.7,Sn98.5Ag1Cu0.5,Sn96.5/Ag3/Cu0.5Any of the components contains silver. Silver has good strength, fatigue resistance and plasticity. The copper component is stronger than the bismuth component. Bismuth is a relatively brittle element.

Of course, what is mentioned here is all about usageLEDLead-free solder paste is also availableLEDIn order to save costs, manufacturers will choose to use itLEDThere is lead solder paste (mostly found in China.LEDOn the product.

What kind of solder paste is suitableLEDThe industry should be determined based on the actual situation of the products one makes. JJY is professionalLEDSolder paste manufacturers. If you have any other questions that you don't understand, please feel free to call for consultation.
