Bakon BK950D

[stj]

just got one.
so as you do - i stripped it

soldering and component placement is good.
quality feels good.

input is fused, has an inrush limiter & a choke before the rectifier.
nice design

well worth £18 i spent on it!!


now the fun part - i know your all wondering.
the caplist!

primary smoothing,
100uF 400v 18x30mm CHONG brand 105' no series marking.

secondary's
1000Uf 25v 10x20mm JWco brand CH series??
1000Uf 25v 10x20mm AE brand KF series.
and
2x 22uF 50v 5mm AE brand KF series.



so, who can find datasheets for CHONG, AE & JWco ??

Re: Bakon BK950D

Hello stj

Where did you get it from? what place and if I get it I need a UK plug.
Also how do you solder a mini jack from 2 satellite speakers????

Also how do you solder a lcd connector on a broken lcd screen.

I just cut off the plug and fitted a UK one.

Re: Bakon BK950D

The secondary capacitors are low-ESR series, given that there is a 400V unit in the power supply primary.

Re: Bakon BK950D

are the t12 tips that aliexpress sell ok? as i may order one of these irons plus some extra tips as some sellers sell about 8 in a kit

No complaints here. I use the chisel T12-K that came with the iron and a fine tip with a small bend T12-JS02 the most (£4 delivered).

What fuse do you put in the new plug ?

What amp? 13amp, 5amp, 3amp???

Some videos say it is faulty!!!

Re: Bakon BK950D

There will always be some defects with pretty much every product made.

I have a 3A fuse in mine.

Re: Bakon BK950D

I got a euro to UK plug adapter, it came with the item.
It states on it that it should be grounded, but the device only has two plug connectors. The uk plug adapter has three.

So how do I make sure the soldering station is pluged in correctly?

WITH IT BEING GROUNDED.

Re: Bakon BK950D

Why not just cut the plug off and attach a UK one ?

Post a photo of your plug and equipment.
To show me what you did inside the plug so I can copy, thank you.

Re: Bakon BK950D

You don't know how to wire up a UK plug without a photo ?
Or are you saying the mains wire on your 950D had only two wires and no earth ?

That is the adapter needed. I want to see how you did it pal.
I got to make sure I do it properly, your mobile phone has a camera on it.

Also what braid and solder do you use for your work.

[diif]

Re: Bakon BK950D

No adapter. As i said, cut off the non UK plug and stick a UK one on. It's three core that comes out of the Bakon.

Solder from RS, Chemtronics braid for BGA, Gootwick for smaller, Amtech 559 flux for important jobs, cheap Kingbo in a syringe for eveything else.

Photo of some of my bits including how to wire up a UK plug.

Re: Bakon BK950D

How do you get rid of the flux on your items, how do you remove the flux off the motherboard.

Re: Bakon BK950D

IPA and a brush followed by a wipe with a clean room wipe.

Chong: Shit, get rid of it. ChongX is better, Chong is fake, ratings usually aren't true.
JWCo: Largest capacitor manufacturer in the world, 1 billion caps per month produced. I have one in a fish tank that I have, 5 years old and still going, I don't think JWCo is that bad, they're definitely not that great though.

Can't find anything of AE, probably some random generic.

Re: Bakon BK950D

Hello, I also got a Bakon 950D, 75W soldering station. Did you guys check with a power meter? My unit uses much less power than claimed. A T12 tip is about 8 Ohm, the station outputs ~19V, which gives only 45W.

Google this: UnionTest UW501
That is a (russian) station that looks pretty identical to the 950D, but it truthfully claims only 45W. I have the suspicion that many 950D units which are advertized as 75W are in fact only 45W. So, 40% less powerful. I feel a little bit cheated. Did I miss something? What do you think?
