What is the best way to manually apply solder paste?

Manual solder paste scraping is a critical step in hand soldering or rework during electronics manufacturing, requiring a balance of precision, efficiency, and safety. Below are detailed step optimization methods and precautions to help you achieve optimal results:

What is the best tin alloy content for solder paste in general?

Tin alloy content (85% ~ 92%) in the welding performance, process suitability, cost and environmental protection to achieve a dynamic balance between the specific selection needs to be combined with the size of the component, heating mode, reliability requirements and other dimensions of a comprehensive assessment.

What type of solder paste is needed for smart wearables?

Intelligent wearable devices in the production process on the choice of solder paste need to consider the welding process, component characteristics, reliability requirements and environmental standards, the following is a specific analysis:

The Prospect of SAC305 Nano-Solder Paste and Microwave Hybrid Heating

SAC305 has been widely used as a substitute for lead solder on the market. The reliability of SAC305 has always been a concern in the industry.

What are the Competitiveness of Anisotropic Conductive Adhesive (ACA)?

Semiconductor packaging is now moving towards miniaturization, with increasing packaging densities. The new mini-LED display has developed rapidly in recent years. There are tens of thousands of chips on a mini-LED screen. Besides, the chip soldering temperature range of mini-LED is large, and the P-N pole spacing on the flip-chip pad is only 40-50

Application of Laser Solder Ball Soldering Process in Microelectromechanical Products

Microelectromechanical systems (MEMS) are systems that integrate miniature mechanical and electronic components with sensing, control, and actuation functions.MEMS products are widely used in automotive, medical, communications, aerospace, and other fields.
