Due to the large heat capacity and slow heating rate of thick copper plate welding, wave soldering is prone to missing solder. Selecting high-wettability solder bars can significantly improve the spreading ability of molten solder on thick copper substrates. Combined with the collaborative optimization of process parameters such as increasing the preheating temperature to 130℃～140℃ and reducing the chain speed to 1.0m/min～1.2m/min, it effectively solves problems such as insufficient solder joints, bridging defects, and cold solder on the back of the PCB.

Using Jiajinyuan high-wettability solder bars can significantly improve solder climb height and the consistency of fillet formation, with particularly pronounced process advantages in structures with copper thickness above 2oz, large-area copper foils, and multilayer thick-copper constructions.
Published: 2014-08-25High-wettability solder paste directly determines solder climb rate and void control in the soldering of fine-pitch devices such as QFN/DFN. Domestic solder paste brand Jiajinyuan covers the full spectrum from no-clean ROL0 to water-washable ORH1. Its 8MQP/5RQ series achieves nearly 100% solder climb, while the 8M9P/5RR series has an extremely low void rate and is suitable for automotive lighting. The selection of SMT solder paste must match the coupling relationship among alloy melting point, flux activity, and cleaning process.
