September 7, 2026 Kester NP510-LT HRL1 Low Temperature Solder Paste
The Kester NP510-LT HRL1 Solder Paste is a low-temperature chemistry designed specifically to work with MacDermid Alpha’s low-temperature HRL1 alloy. Engineered by Kester, this formula offers peak reflow processing at 190 °C while delivering drop shock and thermal cycling performance comparable to standard SAC305 alloys in appropriate applications.
Mitigation of Thermal Defects and Warpage
By lowering the processing temperature, Kester NP510-LT HRL1 Solder Paste significantly reduces board and package warpage during reflow. This thermal mitigation prevents severe assembly defects, such as non-wet opens (NWO) and head-in-pillow (HiP) failures, ensuring higher board yields on complex manufacturing lines.
Fine Feature Printing and Process Compliance
The advanced formulation of NP510-LT HRL1 Solder Paste enables precise fine-feature printing, long stencil life, and low voiding across various integrated circuit package types. Classified as ROL0 under IPC J-STD-004B, it is a zero-halogen, RoHS-compliant solder paste ideal for temperature-sensitive electronic assemblies.
