Revocation of Engineering and Installation of Switch On / Off

Tips and tricks to make the removal and installation of switch button or switch on / off on mobile devices, these problems sometimes seem very trivial or very easy, but if we do not know the techniques in conducting the removal or installation of switch on / off, it will cause impacts very heavy as well, when performing revocation missalkan switch on / off going off track or lifting of track on the pcb mobile phone that is under the switch button on / off, due to this damage ultimately we are required to perform engineering jumpers, while if we really have to understand how how to remove or revoke the switch on / off correctly, then it is so very little to happen. Below are the steps and preparation and techniques in conducting the removal and installation of switch button or switch on / off.

Revocation techniques Button Switch On / Off
You can use tweezers or tongs board pcb board for easier and reduces the shift of PCB during removal and installation of the switch on / off, to replace the button or switch switch switch On / off, you should use the two eyes of solder to avoid damage to the PCB track, two eye solder is used in a sleeping position, especially at the switch On / Off which has 4 legs, make sure the solder has sufficient panasn eye and make sure to use eye solder that has a pointy tip of the eye and the tip of solder to stick to tin,
after making sure the tip of a good solder and solder paste tip of the eye in a state of sleep at the foot of the foot switch on and let stand about about 5 -7 seconds until you see the tin of the foot switch on melt and fluid look, after the molten tin solder upward shift both to attract switch is defective. After the switch is lifted clean the rest of tin on the phone PCB by lifting the remaining tin using fiber wire if needed. In other electronic circuits used vacuum pump for removal of residual tin tin but in a series of phone wire is used because tin fibers are left not so much that by using the fiber wire is enough.
 
Mechanical Cleaning Time Lead On Board PCB
Place the fiber wire on songka pasta, then lift and place it in the space of a remaining tin be cleaned. The position of the tip of the solder wire is placed over the fibers set aside some time after making sure liquid tin under fiber cable, fiber wire sliding along with the shift towards the top or solder side of the residual tin was also lifted and attached to the fibers so that the wire lead on the PCB surface flat, After tin on the PCB, the average on / off switch is ready to be installed.

Installation Techniques Button Switch On / Off
You can use tweezers or tongs board pcb board for easier and reduces the shift of PCB during removal and installation of the switch on / off, you can simply use a single solder eyes, before the switch On / Off the newly installed you should check in advance by using a multi tester , make sure the switch On / Off which will you put in a good condition or can be used, Put the switch On / Off on the right track position is on the phone PCB. At the end of the eye tin solder berries to taste and place it on foot - the foot switch On / Off that you have your place and hold with the help of tongs or tweezers on cell phone PCB, solder one by one to have been soldered onto or imprinted well on the phone PCB. Make sure do not get between the legs legs connect as if connected then the switch will automatically switch On without pressing On / Off.
Direct testing mode you can do with the way the battery on the back casing insert the phone, then place the phone PCB and press the switch On / Off without closing the PCB with the phone casing, after pressing the switch On / Off on the phone then the phone has been able to live and this means installation has been successfully performed.
