Ok, I normally refrain from posting small inquiries like this because I usually realise I was just being dumb, but I just wondered if anyone has noticed this.
My leadfree solder reel ran out, I got it 2 years ago from Rapidelectornics. Nothing overly special, its their "premium" with silver (95.5/3.9/0.6 Sn/Ag/Cu) with 3% RMA flux. 0.7mm. 500g was about £50. Same reel, now is £130. I realise the 99% Sn stuff is cheaper, but I much prefer SAC305 or similar, so I'm always going to pay over the odds, but even going on RS I've noticed that their standard SAC305 0.7mm 100g is a good £35.
As I said, I haven't bought solder in a couple of years, so prices are going to change (and usually on the up) but it's pretty much doubled here, at least going by the usualy sources.
On a more specific note, anyone have experience with this solder:
https://uk.rs-online.com/web/p/solder/0555276It's the cheapest for SAC305, but as I've never used this brand, I dont' know much about the flux used - A11, as it's significantly cheaper than their "RT15" that apparently is recommended for rework. 2.2% would be a minimum for me (prototyping SMD, TH and some smallish connectors). I have no doubt the brand is reputable, RS are pretty reliable, but I have imited experience in the different fluxs used in solder - always just gone for rosin/RMA and it's worked.
