Recently my G613 got few keys starting to not responding, double type, or even triple... ( numpad area ), including the Enter Key from Numpad too... when it's not working, i pop off the keycap, blow into it, and it works for a while before back into not working. same for other keys... what's wrong?

I used Contact Cleaner, alcohol too.

I am looking at solder kit sold on shoppe...

those one with a bag... inside it has the solder wire.... ( is that what you call them )... will that be okay for use on soldering keyboard switches?

if i remember correctly... i read somewhere that the solder wire has size and must use xxmm on certain soldering on pcb.

This one says adjustable heat..... not sure about the solder wire diameter....

Do i need to put a thin coat on the switches bottom pin before inserting into the pcb?

How hot is too hot to avoid damaging PCB?

not very versed in soldering terms... lol....

those solder kit in a bag cost about 40 - 50 is good?

what you use?

i am from Klang. yet to buy switches.

So i bought this and waiting to arrive....

I only done once soldering back at high school , and i think it's been 8 years since then. I not really sure how to desolder and solder.... Youtube makes it looks easy... but i afraid i might mess up and destroy my keyboard's pcb, like the pad (contact hole on pcb ) raised... any idea to avoid that?

My Keyboard is G613, it's mounted on a plate ( i think it's metal painted in black ), and i read somewhere after desolder , have to use some plier or tweezer to remove and gently too....

lol... how to avoid that? how it got damaged? too hot? or the soldering iron touched too long?

and got specific solder wire to use? or the one included in the kit is sufficient?

I used Visbella Electronic cleaner, and then used hair dryer in cold to accelerate the drying.

It works fine for a day and then back to no register, double/triple type.

Will remember that.... you do soldering before?

May i ask your opinion on which switch is better durability/lifespan? Romer G, or Cherry switches?

Oh... i bought the soldering kit, might as well experience it myself first. how much he charge per key? i also bought a bunch of Romer G switch from Shoppe.....

anyone can help me choose solder wire for soldering keyboard, there's so much brand, size on lazada/shopee.... which one to choose?

0.6mm? with resin flux core? i am looking to buy it and keep for future uses if needed.... any brand will do?
Thanks for your offer though

Hi, I want to ask about your Logitech G513 keyboard problems, same as mine G613, except it doesn't have led.... how many keys you have now? Mine have 10 keys.... most Numbers (numpad with NumLock key ), right arrow.

I mean how many keys you have problem with now? I have about 10. Mine's G613

one more thing i'd like to confirm with soldering, How much temperature should i set the soldering iron at for soldering the switches with a 60/40 solder wire?

Switches and soldering tools arrived few days ago, soldered new switches in, works okay...

The older switches which i suspect have double click actually is fine, i used greases, and carefully put on four corners of the housing, and some thin layer on the actuator, and carefully not touching the contact pins... and soldered back in, and it's been very responsive like when it's new.

The keyboard now works fine.

I experienced de-soldering and solder it back with everyone who helped giving me tips and guidance , and now i am not that nervous , and surprisingly it's pretty easy.

the switches :

- the switches quality looks totally legit, with different plastic texture compared to factory switches, but they are 100% identical with G Logo and omron logo, no defects of any sort.

Do switches need greases? is it key chattering due to dried up greases over the years?

I lubed with automotive greases on ' double registering switches ' and it's back to okay again... so, the switches are actually faulty or just need lubing?

I dissembled the new switches i bought from china and there's seems to be some transparent greases on the actuator... so it must be when over the years, the greases will gone from all the pressings?

I read about the terms ' lubing the switches ' for cherry switches, does that also to all switches of all makes? like Outemu, Cherry, romer-g, Gatereon?

I see.... i opened, the lube is thin and only cover the actuators, the side housing where the friction is none.
