The increasing use of OR fluxes in electronics assembly is driven by several advantages: VOC-free formulations, excellent soldering performance, and improved cosmetic appearance. However, these benefits can come with challenges. Certain OR fluxes may create compatibility issues with solder masks, resulting in effects such as blistering or whitening. Fluxes are classified according to IPC-J-STD-004, while […]
