Medium-Temperature Solder Paste for Electronic Assembly: Recommended Domestic Solder Paste Brands

Medium-temperature solder paste for electronic assembly is irreplaceable in soldering temperature-sensitive devices such as LEDs, crystal oscillators, copper wire lights, and transparent displays. The 8M/2R series medium-temperature solder paste launched by domestic solder paste brand Jiajinyuan is compatible with alloys such as Sn64Bi35Ag1, with a melting point of 151–172℃ and a soldering temperature of 195–220℃. It balances wettability and low thermal stress, and ensures printing accuracy with T2.5–T5 grade fine powder particle size, making it a cost-effective choice to replace imported medium-temperature solder paste.

Repair Prototyping: Which Brand of Domestic Syringe-Packaged Solder Paste to Choose

In repair prototyping scenarios, syringe solder paste selection must balance solder wetting performance, residue transparency, and equipment compatibility. Among domestic solder pastes, the Jiajinyuan 8MQP/5RQ series achieves nearly 100% solder wetting on QFN/DFN devices, while the 8MNTTP/5RNTT series contains only 100~200ppm of halogens with transparent residues, making it particularly suitable for high-precision repair solder paste needs such as mobile phones and Bluetooth devices.

What is the difference between solder joints made with silver-containing solder wire and ordinary solder wire?

There are significant differences between silver-containing solder wire and ordinary solder wire in solder joint wettability, mechanical strength, and thermal fatigue life. Silver-containing solder improves the tin climbing height because silver reduces the surface tension of the molten solder. Meanwhile, the silver-tin intermetallic compound is denser, increasing the shear resistance of solder joints by more than 15%. The selection of solder wire must be comprehensively determined based on PCB copper thickness, component pin plating, and reflow peak temperature.

PCB Circuit Board Soldering: Actual Test of Domestic Solder Paste Brand Performance

Multiple domestic solder pastes were tested for key indicators including QFN solder climb rate, void control, and residue transparency. PCB solder paste selection must match the specific process window. The activity of soldering paste is inversely proportional to its halogen content. Domestic solder pastes now cover the full gradient from zero-halogen ROL0 to halogen-free ROL1. 8M9P/5RR achieves automotive lighting-grade low void rates, while 8MNTTP/5RNTT achieves over 90% solder climb on high-density pads of mobile phone motherboards.

0201 Small Component Printing, Recommended Domestic Solder Paste

Addressing the printing challenges of 0201 small components, domestic solder pastes need to balance the high-resolution transfer rate and low voiding rate of fine-powder solder pastes. Two 0201 solder pastes, Jiajinyuan LFP-JJY5RNTT-0307 and LFP-JJY5RR-0307, are recommended. The former contains 00507BN/T5 fine powder with 100~200ppm halogen, suitable for high-precision consumer electronics. The latter is halogen-free ROL0 grade with T4 powder, featuring outstanding thermal cycling reliability, and has achieved 98.7% solder joint coverage on mobile phone motherboard production lines.
