So I recently bought a Korean A.87 PCB from DanGWanG, and although it may not be an easy project to get going, I've decided to give it a go.
I have the diodes and stabilizers, switches are on the way, but I'm already at a road block :p
I'm trying to figure out a way to get diodes into my Korean A.87 PCB, except when the diode is in(either going through top or bottom) the switch cannot fit comfortably onto the PCB..
Alaric told me I could get In-Switch Diodes, but I don't really want to do this because it would be hard to switch switch types later on.
Is there any other way to do this? Maybe I'm missing something plainly obvious :/
Any help is appreciated!

are you plate mounting? if not it won't be hard to mod the switches later. i don't know if that PCB has 'external' diode holes, or potentially SMD pads, but if not you will need the in-switch diodes.
actually now that i think about it you MIGHT be able to just solder SMDs to the diode holes... i want to say it was litster who posted a video on how to do it. it looks really hard :(
-
Pictures of the PCB may help. We need to know exactly what we are working with here. :)
-
Post a pic close up of where one switch needs to be soldered of both sides so i can get an idea of what your dealing with.

it looks like you're probably going to need in-switch diodes or to use SMDs on the underside.
-
That is the A.87? I thought I always called it the AiKB. Huh.
-
You can solder through-hole diodes without actually putting the leads through the hole. Just solder it on the surface pad. It takes a little more control, but doable.
-
Thanks for the quick responses! Unfortunately I won't be able to post a pic until later tonight, sorry I should have thought about it!
I ordered a ANSI 125 plate just to see if it would work with this PCB, if not I can use it for my storm.
Will update thread tonight with pictures!
-
The pcb is winkeyless so an ansi125 plate wont work
-
That's deceiving considering the PCB has an 87 in the name. Oh well I suppose. :)
-
I had my suspicions, what plate would work dan?
-
Pictures are up in OP!

Exactly my thought process :D
-
You'd need an ANSI 150 plate.
-
You'd need an ANSI 150 plate.
And you are 100% sure? :)
-
I believe so, wait for Dan if you don't trust me.
/me does the Dan Dance.

Base on the pic, the pcb is design with DW(switches with diode) switches in mind except for 3 keys having LEDs. Its probably easier for you to place those through hole diodes into the switches. Its still possible to transplant other switch type stems and springs after soldering switches on.
-
Btw, winkeyless is case-dependent (not PCB), assuming the PCB has 1.5x modifiers. If you have a PCB that has modifiers in configurations 1.5x - 1x - 1.5x , then you still have a choice of going winkey or winkeyless.
Anyways Gupgup, the pic you sent me in PM has 1.5x - 1x - 1.5x modifiers, so you'll need the ANS150 plate to fit.

I have a spare ANSI150 plate for a phantom that _should_ work with that PCB, if anyone can confirm, I can hook you up :)

That would be awesome K!
Ill PM you!
And WFD you can make my order just one ANSI150 now please :)
Thanks for help guys!

Don't think it would work since the function row is higher then the a87 PCB
-
KMiller measured the Plate for the ANSI150, space from number row to F row = 28mm
When I measured the same space on the PCB it was roughly 25mm..
Not sure what to do :/
-
Can you PCB mount it?
-
You may want to measure again, 3mm is not a very large difference.
-
The diodes and switches kind of make it so the switch can't lay flat, so with the normal diodes no I can't.
But with SMDs the prof tells me it can be done, except I don't really understand what an SMD does..
-

I don't really have a specific measuring device I can use, but I'll try it again!
-
SMD is surface mount components.
-
yo ushould be able to PCb mount everything and smd diodes would go on the back of the board
-
It appears I was off my first measurement, it looks almost perfect!
-
yo ushould be able to PCb mount everything and smd diodes would go on the back of the board
Would this still need to be done even with a plate?

would what need to be done if you use a plate?

SMD's, I assume it would still be needed, but maybe the plate makes a difference with the switch and diode, IDK honestly haha

Pictures (http://imgur.com/iTRnQg1,2O7fw3D,2chWwng) Sorry, I needed that for when I'm on my tablet. Glad it's about the right fit, you may have to hit up Kmiller8 for his plate. :)
-
yo ucould do in switch diodes, SMD or do through hole on the backside but cut flush on the top
-
Which would be easiest, and where do I get, and I'll decide right now!
