New Around Here
Hey all,

I have no idea how to open them. I want to make photos of insides of router and have no idea hot to open those cans. Could you be helpfull enough to give me advices or point me to any link dealing with my case?

Best regards, PANUmaster.
 
They usually have screws beneath rubbers or stickers, you need to take them out first and then you can remove the top cover, but it depends on the specific model. Whats yours?

PS: You will loose your router warranty after opening.
 
D-Link DIR-890L.

I dissassemble whole construction with radiators etc. but now i need to take out covers of each chip. And i can't.
 
Can't speak to that particular device, but most are either pop-tops/clipons, or they're lightly soldered on - depends on the OEM's manf. process...
 
I wanna give up on this. But since you reply to my post i might do it again and send here close-up photos of my problem.
On Asus AC-RT87U it was easier... meh. I am just too old for this.
 
You mean the shielding? Show us a picture.
 
Yes shielding. (i will upload pictures when i will have access to my workstation)

You need desoldering to take the thin metal shield off. You need to remove both top and bottom cover to get access
to the bottom of the PCB
 
Virtually all the RF cans I've found in routers are pop-tops. BUT you need to be VERY careful when prying off the tops to not damage components and circuit traces.

Use a magnifying glass to make sure that any place you are going to put your prying tool doesn't have any itty-bitty components or circuit traces. Of course, if you don't care whether the router works after, you can ignore this advice.
 
LOL, good advice :)

I also never saw any shielding being soldered, so far they all could be removed without need to disoldering.

Shielding is not only top part, isn't it? If that is the case it is partial shielding.

Not sure what you mean. The sides of the can are soldered to the board. Just the top comes off.

The sides are part of shield. Purpose of shield is to contain 100% the unwanted spurious or harmonic RF emission . If this is not the case, it is only window dressing. Nothing difficult to understand about this. OP mentioned can, top alone is not a can....
 
This almost goes into the geezer thread - lol...

We did pop-tops on the initial boards, but slowly moved over to solder downs, mostly because of cost savings... just made it a pain when we got something back from the field - our lab techs did a nice job of removing the cans, but they had the right tools to do it - and they supported both Eng/Dev and the production lines...
