During the construction process, it is necessary to determine the coordinates and heights of various lamps, switches, sockets and distribution boxes according to the circuit diagram and the practical conditions, so as to identify the direction of the line pipe and the branch meeting point. So, what should you pay attention to when wiring and pipelining operations? Let's take a look at these techniques and methods!

The indispensable components in electronic products are inseparable from welding processing, so welding common sense and the temperature resistance of the raw materials of the product are equally important. As a manufacturer of new energy circular contact products, users often ask more questions when selecting models: the temperature resistance specifications of the board end pin holders during welding. In fact, plastic materials have different temperature resistance due to their different characteristics. Connector products that have been tested and verified generally pass wave soldering and reflow soldering without any problems.

So what is the difference between wave soldering and reflow soldering in new energy circular contact products? The use of wave soldering is mainly used for soldering pin components, while reflow soldering is mainly used for soldering chip components (SMT)

In wave soldering, the heater temperature is set higher in this area of ​​the reflow section, so that the temperature of the component rises to the peak temperature quickly. The soldering peak temperature of the junction box in the reflow section varies depending on the solder paste used. Generally, it is recommended that the melting point temperature of the solder paste plus 20-40°C. For 63Sn/37Pb with a melting point of 183°C, solder paste and Sn62/Pb36/Ag2 solder paste with a melting point of 179°C, the peak temperature is generally 210 to 230 degrees, and the reflow time should not be too long to prevent adverse effects on SMA. The ideal temperature profile is the smallest area covered by the "top zone" that exceeds the melting point of the welding.

Therefore, when selecting new energy circular contact products, in addition to considering the raw materials used in the connector, it is also very important to consider the welding process.
