  • wire termination for screw terminals - Page 1 - EEVblog
    Solder cold-flows under the typical clamping pressure of a screw terminal and the connection *will* loosen and become unreliable The only possible exception to this is tinning the very tip of the wire, to aid keeping all the strands together, as long as the screw clamp bears on the bare copper strands behind the tinned tip and doesn't bear on the tinned part
  • How to correctly create PCB screw terminal PCB footprint?
    For terminal blocks I prefer to use large, oblong shaped pads that offer some mechanical stability and heat dissipation For pad size I basically go as large as creepage limits permit Be sure to derate the current by 50% in order to keep the temperature of the screw terminal within operational limits
  • KiCAD library for screw terminals? - Page 1 - EEVblog
    Re: KiCAD library for screw terminals? « Reply #3 on: August 13, 2016, 03:40:48 pm » I thought those where included in the stock libraries, but I use my own libraries so I can't check
  • Alternatives to terminal blocks for frequent wiring connect . . . - EEVblog
    Sping will move as the solder cold flows and doesn't lose tension like a screw terminal could Takes a lot more creativity to over or under tighten it, etc Both should be pretty reliable if done correctly, with good quality components Spring clamp ones will be more variable with quality, screw will be more variable with use technique
  • ring terminal to PCB connection - Page 1 - EEVblog
    Hello, I have a BLDC motor control PCB (custom board - 15A peak) The requirements for that board is to have low profile (max around 15mm-20mm) The chosen BLDC come with ring terminal crimp that need to be connected to "Mac8 M2 Screw Through Hole Tap" using a screw
  • screw down PCB terminal blocks? - Page 1 - EEVblog
    Terminal Block - screw or spring NOT a two piece Must have holes for screw attachment to PCB If you come up with another dis-qualifier, I GIVE UP and you are on your own Here is a ten minute search on a supplier of electronic components
  • What the heck kind of terminal screw is this?! - Page 1 - EEVblog
    "Wiha 28320 #1 x 90mm Insulated SlimLine Slotted Pozidriv Torque Screwdriver" I think I will have to grind it down to a slightly smaller diameter in order for the bit to fit inside of the screw terminal hole, but I believe that a #1 is the correct size (or close enough) I'll definitely try and give an update on how well it works
  • High Current ( lt;100A) bolted terminal to pcb? - Page 1 - EEVblog
    You really shouldn't bolt a ring terminal or the like directly to a PCB as the epoxy will progressively crush over time leading to less and less contact force It might take weeks in the case of only using flat washers, or it might take months to years using conical washers (e g - Belleville) but eventually the connection will fail due to high resistance
  • Methods for making a PCB mounting hole in Altium Designer - EEVblog
    You could add a 3D model to each screw hole in the METHOD 1, but you would have to align it one by one, and here its all pre-done problems:-this METHOD gives errors when processing the PCB as it is an object in the PCB not referenced in the schematic-I also tried creating a schematic library part, and adding the above mentioned PCB library footprint(pad) and 3D model to it - now I had to hide unnecessary bloat items in the schematic-same Eurocircuits fabricator problem as above METHOD 3
  • Crimp *and* solder a crimp connector? Good? Bad? Why? - Page 1 - EEVblog
    You can attach a heat sink to the stranded wire as you solder, to reduce the wicking effect, but you can't really stop it The result is a wire that breaks after a few flexes If you have crimped properly, forming cold welds between a clean wire and a clean terminal, the joint will be more reliable that solder by some orders of magnitude
