Hi all Cool

All the Montrealers know Addison I think.

Personnally I think that I was stuck by the specialist of wires.

First of all I hate the US AWG system

I need 0.14 mm2 wire and 1mm2 wire

The specialist said to me to buy awg 35 (for 0.14mm2) and awg 22 (for 1mm2) . I had examples with me . He looked and he said: visibly it is awg 35 and awg 22. I thought that he( was going to use a correct tool .....not at all Crying Cursing Drool

I am very perplexed for the awg 22. So I decide to buy awg 24 (1mm2) and no awg 35

In my stock I still have of 0.14mm2

I want to use my soldering station (SBK 939D) . What is the good temperature for 0.14 mm2 and 1 mm2? I read on the net 450 C and on another place 350 C

Temperature charts on the net we find '' 25 in the dozen''

Thank you for your reply guys

450 degrees sounds rather high, I normally use 350 degrees. I think for most soldering stations, 450 degrees would be the maximum temperature they could use.

There might be occasions where you would use even less temperature, for example where you were desoldering components from a PC board, to prevent possible damage to copper tracks on the PC board.

Thank you Bigdaddynz Cool

I am an electronics engineer, and there are a lot of different opinions about this. When I did a 1 day basic soldering course (run by Weller), we were told that unless there was some particular requirement, the "standard" temperature was 425°C.

For desoldering components (especially surface mount), I have found a high temperature to be better -- heat up and melt the solder really quickly, before the heat flows into the component or too far down the tracks. Adding solder to the joint can help increase the thermal mass so it stays hot as you work each end.
Cheers,
Damon

With soldering, especially when plastic parts are involved in the area (insulation or components on track or circuit boards) then hotter can be better because its not the temperature but the heating time that is the problem. As alluded to in the soldering case, the damage occurs when the non-metal parts are heated up too much. So soldering thin wire, you don't have much metal to heat on the wire itself, but what are you soldering it to? If you solder it to track - where a lot of metal is present, then higher temp will let you heat up the solder on the track quickly (before the heat can transfer down the rail to melt the ties) and then quickly attach the wire, and then pull the iron away. But lower temps (if not using specialty solders such as silver solders) is more tolerant of the person soldering as you can hold the iron there longer before the heat damages nearby non-metal objects.

I would start with a recommended temp, say the 425° C, and do some test soldering with the wire and what you expect to solder it to, and see are you melting the insulation on the wire, or having issues with not heating up the thing you are soldering too, and then adjust up or down as necessary (again higher temps and shorter contact can reduce melting - which is counter-intuitive, but requires quick action).

I spent 24 years as a telephone technician when the only electronics were resistors , capacitors & a few transistors to solder along with multitudes of wires . No problem with what temperature we soldered at & there was hardly any fine point irons to use , mainly big heavy points which heated up the item being soldered quickly . Little use of heat sinks on components . Now days with components being so small it is essential to use an appropriate wattage iron along with heat sinks to reduce the possibility of damage not only to components but also PC boards & even wires as they are so minute .

-----Number 1 thing------ is make sure you pre tin the component leads as it makes everything easier to connect . I have never used a controllable temperature soldering iron & not sure if I ever would but it will help those who haven't waved a iron around delicate components & end up with a flume of smoke & a delightful smell of burnt toast waffling up their nostrils . I have always used 60 /40 solder as it seems to be a good mix for most things .

Cheers Tom in Oz .
