There are many reasons why round pin headers and sockets may have poor connections. Firstly, surface oxidation is a common problem; metal contacts exposed to air for long periods easily form oxide films, hindering good contact. Secondly, contamination is a major factor; dust, dirt, and other contaminants can adhere to the contacts and affect conductivity. Furthermore, mechanical damage such as excessive bending, twisting, or improper insertion and removal can damage the contacts, leading to poor connections. In addition, poor solder joints, contact surface wear, deformation, and excessive insertion/removal force are also common causes. Therefore, during use and maintenance, special attention must be paid to these factors to ensure a good connection between the round pin headers and sockets.
