Jiajinyuan lead-free solder paste achieves stable printing of 0.3mm fine-pitch QFN on SMT production lines, with a wetting angle of less than 35° after reflow and a void rate of less than 15%. When paired with solder wires and bars of the same system, it can ensure consistent process windows for wave soldering and manual soldering, avoiding poor wetting or abnormal thickening of the IMC layer caused by mixed use.

Lead-free solder paste and leaded solder paste have essential differences in composition, melting point, wettability, and reflow profile settings. The key to distinguishing them lies in the RoHS marking on the solder paste batch label, the color of flux residue, and the glossiness of solder joints. Since lead-free solder has a high melting point and high surface tension, it is necessary to increase the peak temperature and extend the time above the liquidus, while imposing higher requirements on stencil aperture design, squeegee pressure, and printing speed.
Published: 2024-01-23Lead-free solder for consumer electronics has become a mandatory threshold for export. Jiajinyuan lead-free solder strictly meets the requirements of RoHS and JEDEC J-STD-006 in terms of melting point, wettability, and IMC growth rate. Measured at a reflow peak temperature of 235℃±2℃, the solder joint thrust reaches 4.8N, the void rate is below 12%, and the copper PAD corrosion depth is <0.8μm, fully satisfying the full-lifecycle environmental compliance requirements of EU CE, US FCC, and Japanese JIS for consumer electronics solder.
