Hey, I read it in Popular Electronics in the '60s. It was probably known back in the '30s.

When the 99% isopropyl topic come up, I plugged it into google's "shopping" tab. Prices ranged from 2.79 to 14.50 for a pint of the stuff.

There's a 20% difference in the price between Kester's 60/40 and 63/37 solders.

That's uh, let's see, oh yeah, less than 4%.

That's uh, let's see, oh yeah, less than 4%. <GASP!> Yes, I DID read your post, and Yes, I did understand exactly what you said. To wit... that there was almost no difference in the prices of the 60/40 and 63/37 solders from your supplier. That's why I raised the question about why there WAS such a large difference between Kester's solders. I think it was plain from what I wrote that I was wondering why there was almost no difference in your supplier's prices for solders from (presumably) the same manufacturer, while Kester solders had a 20% difference. (See above.) Must /everything/ be explained in excruciating detail five times over? This happens over and over and over and over and over and over and over and over, and not just to me. It's because people don't read carefully, then think about what they've read. Believe me, I sometimes am about to respond to a post, then discover I'm mis-understood it. |
