6*6 Tact Switch Bend Foot

The Patch Tact Switches' Description

The patch touch Switch is one of the touch switches, and all of its product operating principles are the same. The appearance structure of the patch type and the appearance structure of the plug-in type are different, the base of the product and the pin constitute 90°, the pin is necessary to adhere to the flat, the foot distance of each pin is the same, this is the patch type.

Multiple benefits of The SMT Tact Switches

Because this product belongs to the patch method, it is very suitable for reflow soldering operations. Benefits of reflow welding: 1) When welding by reflow welding technology, it is not necessary to immerse the printed circuit board in the melting welding, but to select the partial heating method to complete the welding mission; Therefore, the welded element is subjected to small thermal shock, and will not be damaged by overheating. 2) Because the welding technology only needs to put solder at the welding site and partially heat the welding, welding defects such as bridging are avoided. 3) In the reflow welding technology, the solder is only used once, there is no re-use, so the solder is very pure, no impurities, to ensure the quality of the solder joint. Chip type touch switch cooperative reflow welding production process, can trudge production power, reduce labor costs, product defect rate low cost savings and other benefits. Patch type switch, it is necessary to use carrier packaging, can trek the sealing and preservation of the product.

The Touch Switches'  Material Requirements

Reflow welding normally consists of 7 temperature processes, touch the switch to cooperate with the production process, and the material of the product must also meet the requirements of the production process. The maximum temperature point of reflow welding is 260°, and the plastic material of the switch should also reach 260° to ensure its inherent temperature resistance. Reflow welding is the selection of machine suction production process, the pin of the switch must adhere to the flatness, the pin is necessary to ensure that it can eat tin, and the pin cannot be oxidized, so it is necessary to ensure the weldability of the product. Switch pin material is best to use copper silver plating process, plating is best above 0.3um.
