Mr. Zheng: 151-1806-0060Many customers have reported that the samples of some touch switches they purchased outside are very useful. But when it comes to actual mass production, the product exhibits significant abnormalities.
So where exactly do these anomalies come from? Many people don't understand, including the business of some manufacturers. Today, we will talk in detail about touch technology for everyone
Why does the switch get stuck?
During our production process, our switches need to be soldered to the PCB board. The welding methods are divided into wave soldering and reflow soldering. Wave soldering is a welding method used directly for connectors,
The normal temperature for use is 230 ° C and the time is 3 seconds; Reflow soldering is a direct soldering method for SMT components, which is usually used in segments. The temperature is generally controlled at 250 ° C and the time is 3 seconds
A process takes about 10 seconds. We have already discussed the issue of blistering on the touch switch earlier, so I won't go into further detail today. The switches commonly used in the market are imported from South Korea
The phosphor copper shrapnel, which has been hyped up online, is characterized by its low price and standard lifespan. Simply put, it has a high cost performance ratio, but its drawbacks
When encountering high temperatures, the curvature of the shrapnel is relatively large, and the feel will become lighter. If there is flux flowing in during the welding process, it will cause jamming. The problem does not occur in a single place
The sealing of the switch body on the product shrapnel is also very important. If the sealing of the switch body is not good, there will be flux flowing into the product during the welding process. So, in summary and analysis,
The problems that cause the light touch switch to get stuck are these two points.
