Re: Leaded Solder Made in China
I was thinking about this and I wouldn't worry too much about supply. Other things have been banned for the general public, but if you look hard enough online you will find suppliers who don't care and will ship them to residential addresses no questions asked.
That said, I'll probably still buy a small amount every month to add to the hoard. If things get really bad, perhaps we could meet a shifty looking individual on a street corner at night, and discreetly In handshake fashion, exchange money for ersin core! On a more serious note, why not buy some lead free for little projects you don't care about so much, it does still work. Save the leaded stuff for better uses |

If anyone would like to see a variety of higher resolution images showing Multicore's early advertising material have a look at this link: https://www.gracesguide.co.uk/Multicore_Solders Quote:
Until now I hadn't been able to find much information about Ersin flux's formulation. However the attached datasheet, which I think was produced in about 1980, sheds more light on the subject as well as the unique nature of the extrusion process originally used to make Multicore. The datasheet is still distributed today by suppliers such as Farnell. Quote:

Re: Leaded Solder Made in China
When buying from China,is this through Ebay I wonder? Also what about import duties?Just done a search and not finding much with nothing at all from China.

https://www.ebay.co.uk/itm/60-40-Tin...YAAOSw7bZeNy~E I don't think the availability of this kind of import will necessarily last, as mentioned at the end of my original post, which is one of the reasons for deciding to act now.

Re: Leaded Solder Made in China
I'm sure I'm not the only one to have noticed the recent sharp rise in the price of some goods imported from China. For example I bought the Jinhu solder reviewed in the opening post for £10.99 (inc) on 21st Jan 2020. The same product is now more typically priced at £17.99. Worse still this means that a reel bought direct from China is now likely to be liable for import charges. In short, the proverbial horse has bolted in terms of the economic advantages of buying leaded solder from China.

Re: Leaded Solder Made in China
I read this thread yesterday and asked for it to be re-opened. I wanted to try some of the Jinhu solder and so looked first on eBay.
There were a number of sellers offering that make and showing pictures of reels with Jinhu labels, but I saw that in the descriptions of the items, under the heading "manufacturer", they were described as "unbranded". This was the case with the listings I looked at; didn't look at every one. Can anyone comment on whether this is typical, and that as long as the pictures show Jinhu, then that's OK? B

Re: Leaded Solder Made in China
I have a sneaking suspicion that any 60/40 cored solder made in China will be comparable to the Jinhu I reviewed but have no hard evidence to support the proposition.
No idea how eBay views listings containing conflicting information (visual or written) in the event of a complaint. Alan |

Re: Leaded Solder Made in China
Curious; if you search eBay for "Jinhu solder", the response is "No exact Matches found". None of the sellers used the name Jinhu in the description of items, but many show clear pictures of reels with Jinue labels.
I'm now looking at Aliexpress and Banggood. B

Re: Leaded Solder Made in China
ฺBased in Thailand for much of my working life and working around the region I've used Thai 60/40 cored solder for almost 40 years, and in recent years have started to build up my stocks back home in Aus't a little more in anticipation of possible future scarcity - which with the travel restrictions of covid has come earlier than I anticipated (Sigh! even 500gms seems a heavy burden in what are usually well overweight flight bags).
I've never had any issues, it has always done the job well - melts, flows and "sticks" as well as if not better than anything else I've used. This is the brand I've been using "ultracore", which is sold throughout both Thailand and neighbouring countries: http://www.ultracore.co.th/utc/product/wire.html and here is is an indication of local prices: https://www.spebanmoh.com/Lead.html I've only used SPE in store, and it seems that they only ship to Thailand, however there are a number of other Thai mail order distributors of electronic goodies that do do OS shipment.

Re: Leaded Solder Made in China
Thanks for that. I've now placed an order form a supplier who shows both a Jinhu reel and a no-name reel in his listing... and we'll see.
It is quite rare that I've been unhappy with electronic stuff from China with the notable exception of anything with threaded parts, which at bargain basement prices, seems to be more of a lucky dip. B

Re: Leaded Solder Made in China
Current price of tin is $34,000 pmt, well up on just 6 months ago. Makes copper look cheap!
The proportion of tin in the solder is important, used to be able to buy these pens that would mark the solder for the amount of lead, can't find them now? Is this a possible problem with the videos? But the temperature only 230C seems far too low as has been mentioned. I have only ever used Multicore, the potential problems of joints failing makes the additional cost irrelevant. But I have a Farnell power supply, and all the joints on the PCB have gone grey and non-conductive. Can't resolder them and the joint cleaner recommended now seems to be unobtainable. How much solder do people use? I have been hand soldering my products for 30 years, and I think I am just getting to the end of the second 500g reel. Ok, use fine stuff for surface mount and thick stuff for connectors, but even so I think this reel has been used for 20 years. |

Re: Leaded Solder Made in China
I think the last time I paid money for solder was in the 60's .

Re: Leaded Solder Made in China
How much solder do people use? (Woodchips).
Today, very little, but in the '80s, I bought and resold well over 500 Grundig CTVs, mostly thyristor line types. To guarantee long term reliability (which I achieved), I used to de-solder and re-solder EVERY significant joint in the line scan stage. Boy did that consume solder. I regularly bought the 500g reels, until one day I saw the 2.5Kg reels giving a significant saving per gram. That lasted quite a while, but certainly not forever. They also had numerous bad joints (mostly thro joints) in the Tuner/IF units, the self seek boards, and some RGB output boards. It was worth it, I asked high price and saw remarkable reliability. Les. Edit. I should add that I used a Weller gun. A semi-permanent calluss on my right thumb knuckle. That required a new bit about three week intervals.

Re: Leaded Solder Made in China
Same here - in fact it may have been a free gift in PE. This was in the late 60's I think. It was terrible stuff!

To this day I prefer a hotter iron bit. My home and hobby iron, a temperature-controlled Antex, is set to 370C for leaded soldering and works very well. My favourite Metcal bit for professional use is the STTC-137 which is rated at 412 C. That's mostly used with lead-free solder but is just as good with leaded (shhh, don't tell anyone I mix the two up, or my solder joints will start falling apart even though they've been absolutely fine for 15 years). Hot iron: get in, solder, get out with minimum damage. Chris

Re: Leaded Solder Made in China
Ah, the 25W Henley Solon, bought in Bridlington about 1962. I still have a working 15W Henley in good condition, but I'm now loyal to my temp controlled AOYUE, but sticking to the philosophy of hot and in and out quick.
That said, I used my old 25W Antex in the garage recently and that was hot! I've been using 0.7mm solder for years, but was given a small sample of thicker stuff and that seemed really nice (more flux?). The Chinese stuff I ordered is 1.2mm B

Re: Leaded Solder Made in China
My Chinese solder has arrived and it is "No Name"; says it is 63/37 with 2% flux (102% !).
I've put a couple of spots down on some veroboard; it melts and flows well and has a nice ring of flux around the edge. But, while it's hot it is silvery and shiny but as soon as it freezes goes dull and it's less shiny than the old Multicore I'm used to. Any thoughts as to the significance of this? B
