Gold-plated board soldering undertakes high-reliability connection tasks in the manufacturing of medical and precision instrument PCBs. Its surface process must balance solderability, corrosion resistance, and long-term signal stability. Gold-plated board soldering is particularly suitable for scenarios requiring micro pads, high-frequency devices, and low contact resistance. Gold layer thickness control, nickel barrier integrity, and reflow parameter matching are key bottlenecks for mass production yield.
Published: 2013-06-11To address high-frequency defects such as cold solder joints, tombstoning, and misalignment when soldering 01005 components on precision small boards in consumer electronics, this solution focuses on stencil aperture optimization, solder paste rheological property matching, and closed-loop control of the Z-axis pressure of the placement machine. By reducing the stencil thickness from 0.1mm to 0.08mm and matching it with the Jiajinyuan J-105F solder paste with a thixotropic index of 2.35, the first-pass soldering yield of 01005 components is increased from 82.6% to 97.3%, while avoiding the risk of pad peeling caused by excessive squeegee pressure.
Published: 2012-01-23To address persistent production-line issues such as excessive voiding, poor solder climbing, and residual whitening in high-precision PCB assembly, this paper directly examines the measured performance of 8M9P/5RR zero-halogen low-void solder paste and 8MNTTP/5RNTT ultra-low-residue domestic solder paste. Combined with QFN device soldering, communication module rework, and automotive LED thermal management scenarios, it explains how low-void solder paste achieves a void rate of <3% through 0ppm halogen control, T4-grade fine powder distribution, and 305 alloy melting point matching, while also balancing PCB solder paste printing accuracy and batch stability of domestic solder paste.
