For your edge connector, I think I would ensure the origin is at the edge, not the centre, so that when it is placed on the board view, it is easy to.

How to fix PCB edge connectors

A Reason To Code 36 Comments.{/INSERTKEYS}{/PARAGRAPH} Me gusta. Quite a few s computers used a card-edge connector for adding peripherals. Only the resistor and caps.. He can arrange the cat5 wires whatever way he likes in the RJ45 plug and fit them to anything he can think of on the other side.. After the PCB or pads wear you can just throw the board away…. Back in the day , card edge connectors were a great way to connect peripherals, ports, and anything else to the outside world. Hackaday is full of the cheapest people ever. Fortunately silver oxide is not too bad a conductor but it might not be quite enough conductivity. And up against the inside edge of a case. The others I harvast from crashed satelites in my backyard. PCI at card edge requires that cut with quite small tolerances or maybe you could put that on corner of board Anyways, too much small tolerances for home cooked boards? Learn how your comment data is processed. Why low-speed? For a port where only a minority of customers are going to connect something to it, it makes a lot of sense, saving on 3 or 4 connectors on millions of computers each. It worked great for the ZX, Vic expansion cartridges, and untold numbers of other devices. Then just place proper set of pads on your board, maybe with a pilot hole or some markings. In a Roomba almost all components wheels, brushes are connected with such a connector. I have received multiple bad ones and the one-man0business refuses to listen to his customers. Quite often test pins on pannelized boards are brought out from all the individual boards to one edge connector on the frame of the panel. And the yes, the PCIe 1x connector is becoming the common use connector for it. Good on [turingbirds] for putting this to use and hacking down a scrap connector… but this is a method that has been done for AGES in production boards. It does, however, put a programming port on a PCB with zero dollars in components, a minimum of board footprint, and uses parts that can be salvaged from any pile of old computers. Now I am wondering if I can just use some solder wick and solder and if I do, will it no longer be an option to use silver? Needing to add a RJ45 socket to each board to program it defeats the no additional parts benefit. I recently soldered 0. The catch is that the plain FPC cables that Molex makes get obsoleted every months, so supply can be a pain. Vias under TQFP and pogo pins is great idea, but needs something to hold them in place. Obviously the PCB part is on the computer itself. Learn more. Rude and just plain unhelpful. I have banned them from my company now :- This looks like a great alternative. Are you plucking the rest of your components from the resistor and capacitor trees in your orchard? Take something like ths, or maybe a SIM card connector, solder it to a piece of PCB, solder wires for your programmer and glue everything to a clothespin or some other clip. An edge connect is wiping type of contact rather than a simple pressure contact. Plus the cable making tool is worth a few bucks at best. Edge connectors worked quite well when they were originally used in dust free environments. The whole panel plugs into the test stand and bam; test 6 products at once. A few Dave Jones videos covers the method in detail. I prefer a zero cost small footprint and not something to mount on a pcb and thus adding costs :. Downside is reliability. Any suggestions? The only real disadvantage is that you are limited in PCB thickness options as defined by the connector spec. It stays in place as it has retaining clips. Reading all the comments, I am a bit surprised at the reactions. No, because this has been around for 30 or 40 years. Another option if you only need a few pins is the USB edge. They were keyed, and you could only put them in one way. I use cone tip pogo pins and made an ISP footprint that has centering holes in the pads. {PARAGRAPH}{INSERTKEYS}Instead of 0. That is — moving or inserting the edge connector clears away a path through any oxidization on the PCB connector. Check link for Tag Connect in article. So they were only just alright in early home computers as it was not hard to remove and re-insert them when problems arose from dust in the environment. Similar setup with four bigger contacts connects board to BLDC motor. Whenever I need to change firmware, I remove jumpers and connect my programmer to exposed pins. You are left with a short connector that have 4 walls of plastic for support. Report comment. I personally think, that with care, such an idea works well. Search Search for:. At least the C64 used real DB9 connectors for the joystick ports…. This saves a lot of space — you can route under a lot more of it on the other side, and I find that two holes are usually enough to position it well enough to program it. But yeah.. I have a broken HDD that uses two rows of small pads and two small holes on the PCB and custom-made looking connector with bouncy on the drive case for connecting heads and servo to the board. So this use of an edge connector is about the best place to use them. I forgot to mention that I usually put this below a TQFP and the vias in each pad are fine because the signals needed to get to the other side of the board anyway. I really like this idea, however I prefer using a PCB connector that can be bought instead of hacked like this one. I buy 16 8-pin clips for 1 dollar. Worse, it was on the same side of the board. It must be an off the shelf connector for any number of pins. As it happens, the PCI connector includes JTAG optionally, not always implemented and almost certainly not usefully documented in any way whatsoever by your motherboard vendor Pins 8 contacts, since the connector is double-sided are reserved for the purpose. Hackaday Links: July 5, 7 Comments. I would try to prevent that ;. I have a CPC and it has tinned 0. The six pins are superjunky, normally. I use some for impedance controlled MHz sine, the not-changing-planes actually has a nice ring haha! They were relatively cheap, and with a big coil of ribbon cable, you could make custom adapters easily. Is this the latest and greatest way to plug a programmer into a board? Of course the connector itself is only half of the actual build. Silver will be fine, one of the reasons it is used for relay contacts is because of the conductivity of silver oxide. The caveat is when some dipshit mixes multiple uses with the same connector in a machine. For mine, I only have the two center pads have holes. After reading all the comments I still think 0. I then thought of using a silvering paste that can be done with a cotton bud but silver oxidizes quickly. I thought so too — got a set for my brother in law for xmas. It was an awful expansion pack system and only existed because it was dirt cheap to manufacture. I only do hobby boards, so cost of headers is not an issue. The fresh connector brings some new gold to the mix and keeps the old connector working. Leave a Reply Cancel reply. This site uses Akismet to reduce spam. Only 4 pins; but the price is right and you can duplicate the effect with just 4 pads and possibly a plastic shim, depending on your PCB thickness. Is it just me, or does this scream for an Atmel ISP programmer system? The TagConnect is such a crap product. It provides 18 contacts on the area barely bigger than SOIC package. I put a card edge contacts on a design we manufacture.
