In order to use the toggle switch correctly, we must remember the parameters of welding, so as to avoid human improper operation to destroy the toggle switch. Do you understand the following points?
1, common precautions for welding
The sliding firing pin should be exactly ON or OFF. (However, in the case of A6E/A6ER, the switch must be placed in the OFF state.) The rotating type should be precisely positioned as [0]. When the position is deviated, the operating feeling may be decreased due to the heat generated during welding. Make sure the switch does not float from the substrate before welding. Multilayer laminated substrates, etc., require prior confirmation tests. Depending on the method, thermal deformation may occur.
2, automatic welding groove (flow welding groove) occasions
Welding temperature: below 260℃
Welding time: within 5 seconds (single-sided substrate t=1.6mm) foaming flux should not exceed the printed substrate on the switch mounting side. If the flux is on the substrate, it is easy to enter the inside of the switch, causing poor conduction.
3, reflux furnace (surface loading) occasions
Reflow welding should be performed under the following conditions. (Measuring point: above the switch) :
< Conditions for A6S-H, A6SR, A6RS, A6KS, A6KSV >
< A6H conditions >
Depending on the reflux tank used, the setting conditions may differ from the temperature around the switch. Therefore, the temperature profile should be obtained in advance, and the temperature applied to the switch body and the welding condition should be confirmed before use.
4, manual welding occasions (except surface mounting type)
Welding temperature: below 350℃
Welding time: less than 3 seconds (single-sided substrate t=1.6mm)
When rewelding is required due to modifications, the number of welding should be up to 2 times. At this time, the interval between the first and second times should be more than 5 minutes.
5, about the use of flux
Due to the type of flux, the amount of application, and the application method, the flux will enter the inside of the switch, which will deteriorate the switch. So please evaluate the flux in advance
