Soldering on capacitors,sequencers

[copaco]

If you don't have female connectors ,can you solder instead on the existing males on electronic parts?Or would the heat damage inners coils?
p.s.Covid-19 getting worse, at 78, I try to avoid going out.Thanks.

Amazon to the rescue. They'll deliver female connectors to your door.

Yes, you can solder components.

Think about any old circuit board especially say a power supply board.

We routinely troubleshoot then replace components as needed no problem.

We solder on replacement Caps, resistors, transistors, chips, diodes, etc

Solder is fine, but don't overheat the connection.

THIS. A 35-40 watt iron works well for most things. Weller is like $20

You can probably over heat the connection (within reason) and get away with it.

I've seen techs totally turn connections red hot and the component still worked.

The components are tougher than most folks think.

30 seconds of heat for most components.

If you can't get a good solder joint in 30 seconds with clean work, (with alcohol), clean tip, and fresh rosin core solder, you're doing it wrong.

A gator clip on the leads between semiconductor, and soldering iron will give you additional time.

What the ?

30 seconds per solder joint? That's quite a strange approach.

You see there are so many different sizes you could be dealing with and it also depends on what size soldering iron you are using and/or what temp you have your pace station temp or soldering iron temp set at

If doing much soldering get some flux. I prefer No Ko Rode. On circuit boards or old connections, a tiny bit helps to melt fast so you dont heat components much at all.

Thanks all.Very useful.

I'm sure some are found on street corners in most cities too....lol...had to go there

Use some thinner 60/40 flux core solder.

Tin the tip of the iron for good heat transfer.

Put the tip on the parts and melt a bit of solder just to get the flux out. Wait a second or two or maybe a tad longer if a big connector or a large copper pad. You are looking for color changes. It will get a bit shiny.

Then flow in some solder till it fills in around and then pull the heat.

A complicating factor is modern boards are all using none lead based solder which has a different look and can affect getting up to the melting point. Once you get the lead solder flowing it changes and works better.

I have done quite a bit of soldering and board repair. I have fixed many pinball machines and working as and electronics engineer does not hurt either. It is not too hard to do. Getting some no clean solder flux might help your soldering. There are youtube videos you can watch to get an idea of what to do.

63/37 solder is worth considering. It is is a eutectic alloy and while a little more expensive than 60/40 it is also slightly better in my view.

The lower (and constant) melting temperature helps reduce the chance of damage to sensitive components.

The quality of the soldering iron is also important. It needs to capable of delivering a great deal of heat in a short time.This will heat up the joint up to the melting point of the solder before the component itself becomes overheated. Fortunately there are some relatively cheap soldering irons with this capability.
