no-clean flux. | Residue under parts is normal in most jobs.             |<br \/>\n| Chemical Behavior | Acids in flux can make films when it is wet.     | These films can cause more leaks and less reliability.  |<br \/>\n| Component Design  | Short standoff height traps more residue.        | More trapped residue means more risk of problems.       |<br \/>\n| Flux Choice       | Flux that spreads a lot leaves more residue.     | More residue can mean more leaks and worse performance. |<\/p>\n<h3 id=\"troubleshooting-7\">\u0627\u0633\u062a\u0643\u0634\u0627\u0641

If you use pads that are too small or have long traces connected, solder can flow away from the joint. This is called \u201cwicking.\u201d The solder moves along the copper trace instead of staying on the pad. You might see this more with fine-pitch parts or when you use narrow pads. Sometimes, exposed copper or long thermal reliefs can pull solder away from where you need it.<\/p>\n<blockquote>\n<p><strong>\u0646\u0635\u064a\u062d\u0629:<\/strong> \u062a\u062d\u0642\u0642
