What environmental conditions need to be strictly adhered to in order to use laser solder paste?

The process application of laser solder paste needs to be based on environmental control as the cornerstone, through the construction of "temperature - humidity - cleanliness" trinity of precision management system, combined with dynamic parameter adjustment and process adaptation

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 are the reasons for PCB pads not being tinned and vias not working?

In electronics manufacturing and PCB (Printed Circuit Board) production process, the pads do not tin and through-hole is a common process defects, may be caused by design, materials, process or environmental factors.

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:

What type of solder paste is needed in the field of micro-optical displays?

In the field of micro-optical display (Mini LED, Micro LED and COB package), the choice of solder paste needs to synthesize the three core dimensions of chip size, encapsulation process and reliability requirements, the specific program is as follows:

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.

Improving Flip Chip Packaging Efficiency and Reliability with Epoxy Flux

The flip chip assembly process typically includes soldering, flux residue removal and underfill. As chips continue to miniaturize, the gap between the flip chip and the substrate decreases, making it increasingly difficult to remove flux residue.

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
