Tony,

? I get the idea now. I was just making sure I didn't need any lead-free stuff.

I avoid it, nasty working on older PC boards that are more fragile.? Iron is too hot and soldering can take too long depending on the lead free solder.


And I am just a hobbyist and still somewhat a noob at that when it comes to electronics. But I sure have learned a lot over the years but keep getting interrupted and cannot stay 100% focused on my projects. Sometimes I buy the same resistors and other components over again.

I buy in bulk, the cost of resistors and capacitors goes down dramatically when buying in 100 lots, but then again, that's surface mount parts.? I' suggest a spread sheet of the resistors and capacitors (and whatever else) you buy, making them preferred parts, and using them where possible.


Some projects feel like I have been working on them for years and I almost have to relearn the software (for a few minutes) to get back to where I left off.

The comments in the code aren't for when you're designing it, they're for when you redesign it 6 months later.?


I have learned buying cables is easier than making them although I have made quite a few, they never look professional to sell. I have tried many pcb softwares but have settled on DipTrace. I have learned that etching my own boards is work that still doesn't look professional enough for me as I have to figure out the silk screening next. Easier and cheap enough to have them made. Still a noob, but getting there...:)

Assuming you use toner transfer, the thick white film is not optimal, but does work.? I just generally skipped that step, but I did put some labels in the ground pour.

RoHS doesn’t bother a lot of people, even if you’re repairing old gear where the tracks fall off if you look at them funny you’re still allowed to use leaded solder.? They’re full of lead and god only know what so redoing a couple of joints in lead-free isn’t going to save too many whales.

It’s not all that complicated, just mainly nit-picking pedantic pen-pushing stuff.? I work in IT dealing with money, so I’m used to that sort of thing.

If you making laptops or whatever you get a statement from whom you buy solder, PCB, wire etc from that says how much lead is in it.? You staple all those together and send it off to the EU and say “our laptops are made from this” and everyone is happy.? Of course this means you can’t buy the cheapest solder from Honest Johns Alibaba shop and things are a bit more difficult if you actually make solder, but that’s not most of us.
