Homebrew PCBs

Thanks Harvey,

 

Yeah I've heard a lot of not so good things about these sorts of contacts.
The reason I went with them is because I have a vintage Mark-8 project I'm
doing and they are typically what was used and have the right vintage look.
In fact, I have a number of vintage home-brew machines with two sided boards
and they all used these.  The ones I bought were from ebay and they were
called 'molex ic strip' - but I don't think that's the right name and if I
search under that now it comes up with the plastic topped ones, which I
don't want.

 

I'm sure they must have a proper name somewhere.. there must still be
millions of them out there - they were used a lot back in the day.

Brad,

Those are stamped and formed contacts. There are a gazillion types on the
internet and ebay. With a quick look, I couldn't identify a source for the
type you are using.

If I were doing what you describe, I wouldn't use those contacts. It will be
difficult to keep the solder out of the top spring contact when you are
soldering them in. Instead, I would use cylindrical machined socket pins,
like this one: https://www.mill-max.com/products/rec/0297. These types of
contacts have the spring socket contained within the body cylinder, allowing
the solder to flow around the entire contact without having to protect the
spring. They are probably more expensive, but will result in less rework and
possible board damage. 

The link I gave above is for a Mill-Max part I picked at random. When I do
this, I sometimes buy some machined contact IC sockets or socket strips on
ebay, and remove the contacts. This is a very inexpensive way to get them.
The strips/sockets are made of thermoplastic material, and a little
encouragement from the heat gun makes them very easy to remove.

Figured if anyone might know it might be you guys.

 

I am making some double sided boards that will not be plate through - so I
need these metal IC socket pins you install in a strip and then cut after
soldering on both sides.  I have a roll of about 500 but will need many
more.. I just can't find more because I don't know what their proper name
is.  I've tried 'IC socket strip' but I get the strips with the plastic
tops.

Many thanks if anyone knows what the proper name is and/or where to get
them.
