Headers / Pins / Crimper Solutions for Off-board Items?

Kirk Kleinschmidt, NT0Z All Messages By This Member #126 Hi, gang, I am planning to do some building / prototyping this winter season and I'm looking for simple solutions to connecting off-PCB controls, LEDs, non-RF jacks, etc. I will be mostly building Manhattan style and surface-mount style in which I will etch or mill a PCB, but all parts will be mounted on the copper side in Manhattan/SMT hybrid style. I'm trying to figure out a workable way to incorporate header pins, singly or in groups of 2-3 adjacent header pins, in this kind of SMT construction style. With through-hole PCBs the drilled holes provide an easy way to mount the header pins. But how do we do this in an SMT/Manhattan style? Are there header pins with flat bottoms (like tiny patio umbrella stands), or should I take a standard header and bend the "legs" 90 degrees, soldering the now-flat legs to the PCB? Assuming I get that issue sorted, can anyone recommend an affordable tool to crimp the pins onto the remote wires? I'm thinking about computer motherboards here, in which the tiny crimped pins are inserted into a plastic header/socket that allows them to be plugged onto the header pins on the motherboard. I think there's also a small "pick tool" that allow the pins to be inserted and removed from the plastic headers? I'm a titch out of date when it comes to these critters, so any insights would be appreciated. Regards, --Kirk, NT0Z ? Rochester, MN

You can buy headers that are already 90degrees.? They are fat enough to solder (if you can do SMD you are well qualified. For wires, I buy? "dupont" cables from ebay, individual connectors are already crimped on each end.? I cut the wire (which is really small, the only problem) and solder to the off board part. If you can make boards, I don't know why you don't just design a custom board?? Far easier for me and end result is much better. 73, Gary WB6OGD
Ryan Flowers All Messages By This Member #131 I'm not a skilled builder. The DC40 was my first scratch built radio, and my first Manhattan style project too. I used these connectors in several places, and I used pre-made pieces that I could solder rather than having to crimp. This is how they turned out, and how I used them. Notice how I used a pad to separate the pins. They're easy enough to bend with tweezers.

Kirk Kleinschmidt, NT0Z All Messages By This Member #133 If I get to the PCB stage it's not that difficult to make a custom board, but most of my stuff is one of a kind or some kind of prototype, so figuring out how to set up remote components with headers/pins is desirable. Thanks for the "dupont wires" reference! And thanks for the pix. --Kirk, NT0Z My book, "Stealth Amateur Radio," is now available from www.stealthamateur.com and on the Amazon Kindle (soon) On Friday, November 8, 2019, 12:27:42 PM CST, Ryan Flowers <geocrasher@...> wrote: I'm not a skilled builder.
