Cold Solder Joints – Identification, Effects, and Prevention
Learn what cold solder joints are, their causes, effects on PCB, and effective methods for identification, prevention, and repair.
Read MoreHome / Characteristics of cold joints
Key characteristics of cold joints include: They are unplanned and unintentional, often caused by interruptions or delays in the concrete pouring process. The delayed placement prevents full integration and knitting between the concrete batches and might lead to reduced structural robustness, increased. A cold joint in concrete construction is a plane of weakness that forms when new, wet concrete is poured against concrete that has already begun to harden. This discontinuity occurs because the older material has passed its initial setting time, preventing a true chemical bond with the fresh mix.
