The issue can be aggravated if the solder paste mask is absent or only covers a narrow area between the pads. When left unspotted, the short circuit created by the solder bridge can cause the circuit to malfunction and, in some cases, damage the shorted components. It usually happens on fine-pitch SMD components, such as a microcontroller on an LQFP package. What are the main 5 Soldering Issues in PCB?Īs the name implies, solder bridging is akin to having a bridge of solder built between two adjacent component pads. If you want to order PCB product, please check and custom your order online. If you are facing the challenges of PCB soldering, please check and read the content we prepare for more information. In this passage, we will tell you 5 soldering issues during the manufacturing process. In just a few seconds of improper application, a soldering iron can shorten the life expectancy of components by decades. The altered bonds change electrical values and shorten component life. However, the connection lacks an intermetallic bond and the high temperature degrades bonds inside components. At soldering iron temperature, solder will stick to oxides and contaminants to produce a visually acceptable connection.
