2015年3月23日 · Creating lead vapour that you can breathe in with a soldering iron is impossible. It has a boiling point of 1749°C, and the melting point is only just below what you are soldering at. If you compare that to water, your solder is a block of ice, and when you are soldering you're melting the ice to tap water (or colder) temperature.

2024年11月21日 · Requirement: grid voltage soldering techniques for safety. Satisfied: with tinned contacts before soldering and heatshrink for HiV insulation. It should be a smooth solder joint that passes a 2kg pull test. The pictures look adequate yet unfinished.

It seems to mean that soldering and epoxy-gluing are used almost simultaneously: you solder first then use epoxy glue to attack mechanical stress issues but "epoxy soldering" would be misleading as the expoxy gluing is no substitute. There may still be cases with epoxy-rosin-lead-mixtures(speculation, plz, attack).

I just bought a Weller WSA350 smoke absorber. It was $50 new. A three pack of filters is pn WSA350F. This works OK. A unit with a stronger fan would be better. After a few hours of soldering there is a fair amount of white powder on the carbon filter. The fan looks like a standard 5" boxed fan so I may try getting a more powerful one.

2018年9月4日 · \$\begingroup\$ One situation that I know of that mandates forced vacuum ventilation of soldering related fumes is when re-working PCBs that have any kind of superglue on them. Accidentally melting some superglues releases hydrogen cyanide (if memory serves).

2021年12月10日 · Apart from the fact that the soldering brings additional metals into the connection and thus shifts the thermoelectric properties into the unknown, there are other disadvantages. The connection can definitely only be used below the temperature at …

2015年3月6日 · Put your enameled wire on its surface and press it down with a soldering iron's tip heated by operational temperature. Aspirin melts, boils, gets in contact with enamel and desintegrates its coating on wire's copper. So you can strip it with the same soldering iron's tinned tip pretty easily in a couple of seconds (up to 10 sec in fact).

2012年2月25日 · Initially, I would think of using a knife for stripping because wire strippers will definitely not work. Then with soldering, too large solder flows are highly unwanted. Someone recommended to heat a small bit of solder onto the soldering iron tip and then letting it flow to the joint. Any recommendations? Thank you!

2022年6月12日 · Neither of these soldering irons is powerful enough. For jobs like this I use a Goot TQ-77 200W pistol grip soldering iron on one side, and an SS350 SOLDAPULLT solder sucker on the other side. The conical iron tip gets right into the hole to heat the solder up quicker than a bevel or spade tip.

2013年12月8日 · Desoldering in theory should utilize the same temperatures as soldering. Flux present during soldering helps reduce the required temperature. The same is true for desoldering, apply some flux to remove contaminants. The melting point …
