can show pic of the Flux that u're using? so far i haven't use flux in my soldering. whats the function?

If the 63/37 compared with 60/40 , which one is better ? I saw 99% tin solder wire before , Is it same ?? And I also saw kesters solder wire on some shop before that , it made in Mexico right ?? Last time I bought a solder wire , and dunno why after the solder wire used to solder some point of connector on PCB will be crack or not shiny any more after a long time .What is happens to this solder wire ? Which Multimeter should I get ?? Analog Multimeter or Digital Multimeter and what brand should I get , Fluke or Sanwa or UNI-T

don't have a working cam with me now so tarak pics. Though I got it from a big big store at the old Jalan Pasar road (the upper portion), next to the banks; they distribute hakko and pros kit.

you don't have to use it if you're using through hole since the Kester I bought you the last time has internal flux. SMD requires more flux if you're soldering tiny chips with tiny pins.

Flux is basically weak acid that cleans up the pads, removes oxidation, making soldering much easier.


euthethic blends (63/37) are better simply because they solidify as a whole. Tin leads (60/40) do not solidify as a whole hence you get cold joints easily.

Sanwa is enough for audio use.

Fluke is for overkill.

EDIT: Always get a digital multimeter (auto ranging even better) so your life is easier.

What is the cold joints? If use 99% Tin Solder wire , what will happens ?

Do us a favour?
Rather asking every single new word that you come across why don't you do some reading? It's not hard to do 'search' you know. Thats what GOOGLE is for!

Which shop got sell Hakko soldering station or Weller Soldering station ?

There is one specific shop that stock all Pro's Kit wares including Hakko irons.
Its the same row few doors away from RHB Bank. From Jalan Pudu entering Jalan Pasar, it's on the left.
Weller soldering station last I saw at NIXIE and some shops in Jalan Pasar. Be prepared to pay big buck$ for them.

If RM 1 K enough for the Weller Soldering Station ? If Penang , Which shop got sell the Hakko Soldering Station and Weller Soldering Station ?

so hardcore? You are just started you journey. Get a very basic one first and see whether you are seriously enjoy this journey. If yes, go ahead buy the best one u can afford.

the hakko 936 is all you need. (or it's equivalent replacement unit since the 936 is discontinued due extreme china clones). Should cost you around RM300-400.

You should also get some replacement tips.

One of the very few things I've learnt about maintaining tips is that do not use the wet sponge to clean your tip. Instead, get the golden brass wool sold at the pros kit distributor to clean your tip. Wet sponge + tips = oxidation.

I used Weller soldering station and other soldering station b4, it is nothing more than controlling temperatures ONLY!
hmmm... a JAPAN MADE soldering gun with power boost button up to 130W is ENUFF if and only if you trust me.

hmmm for solder, i think if u have finalized with circuit then use good solder like PHILIPS for power, WBT or Mundorf Msolder supreme silver/gold for critical path or SIGNAL! HEHE

1-E-9 sen OPINION hahahaha

just so you know, vir_killer is a borderline troll so don't place too much credit on what he says

(especially what he says about silver/gold solder because that's bullcrap)

Could you all please DON'T pollute this very fine thread with irrelevant topics just like others we saw.....if we wanna talk about amps building we talk about amps....simple related arguments is ok but NO to BS.....you know the rules. This thread is long enough and surely we don't want it full with garbage or some cursing posting...

i m not polluting, but little ghostss is personal attacking so i have to defend...
he started it... do not blame me...
and why are u so busy about it? hahaha

I disagree, you brought it upon yourself...

You ARE polluting.

let me show you the facts.



temperature control IS not only about controlling the temperature. You can use it to fine tune it to suit your applications. E.G. High temps for ground pads when you need loads of heat at a small fraction of time, lower temps when the pads can be easily soldered and so on.



silver is shit for solder joints. They are more prone to cold joints than normal euthethic blends. The purpose of solder is NOT conductivity but rather a mechanical item that holds your components down. If you rely it for conductivity you're doing it wrong. Don't give me crap like it flows current TOO because the impedance should be dominated by your copper traces or your copper wires.

hi guys.. im not sure whether i shld post this here onot..

im planning on diy a usb DAC using a PCM2702.. my source will be foobar2k + dell inspiron 6400 win xp (old laptop lol)

found all this from head-fi..

headfi

keces pcm2702

any1 tried tis? was wondering how it sounds..

i can get this chip from farnell for around 70.. worth it?

i need lowyat pro's on tis..

thx in advance!

yes. in normal solder u did it manually... hmmm is tat a must? unless u need the best.

If u using normal soldering station, of course silver is harder to solder. but it depends.. WBT is very easy to be soldered comparing to Msolder... Tats y i say use it only when u have finalize the circuit.

Yes... its true.. but taste could be affected by material of solder... and please don deny about it.

Am i clear enuff to answer ur doubts?

PCM2702 is staple for the lower end DACs. It's like the CMOY of all DACs.

They sound like the typical AlienDAC, neochen miniUSB. Great for the price, but they can only do so much.



I take it, you've never soldered pads connected to multiple big ground planes before.



normal solder do the same thing, possibly even better. You want to hype and have a circle jerk about things that don't bring any improvement, go on and start a new thread to serve your own delusion. This thread has been no bullshit centric for years now (since it's creation), don't bring bullshit into this thread.



cool story bro. There's no such thing as tastes when it comes to something so simple.

talk about unwarranted self importance. Go away.

thx for ur reply!

hmm true.. after some research.. i think i shld merely use it as a usb converter.. need to research more on the dac part..
