Solder Flattening with Parallel Pliers. Further to post #1010. Also see post : [image] Share tips you have come across General Electronics Flattening Solder Ahead of Time Further to post #1015. It can be difficult to source thin solder for SMD work. Very thin solder seems to not have an appropriate amount of flux. .5mm is a bit too large for soldering SMDs and usually results in using too much. Parallel Pliers work well for flattening solder as you go; the main problem is it cuts into your soldering productivity and your soldering rhythm. If you have a hard plastic or metal roller you can flatten solder quite fast and do it … You can flatten solder to aid in hand soldering of small SMD components. Use cleaned parallel pliers to flatten a length of .5 mm solder. With the flattened solder, you have an easier job in limiting the amount of solder applied to your PCB pads. [A] [B] [C] [D] [E]

Using Wire Crimps, 453 U-Shaped You can find Terminal Tab Cold Insert Connectors for sale all over the internet. These are made from brass and are quite reasonably priced, about 2 to 3 cents each in volume. You can easily connect two wires as described in the images below. The connection is strong and does not need soldering. Note, using glue lined heat shrink makes your connection moisture proof. If your connector can accommodate stacking the wire strands, follow the instructions given. If your connector is small, you may not be able to stack the strands as shown.

28 AWG DIY ferrules for screw terminals In another post, a user asked how to terminate 28 AWG wire in a screw type terminal strip. @6v6gt suggested to use a Dupont crimp connector to act as homemade ferrule. Below shows how this process can be accomplished. Add heat shrink to act as a strain relief. The colour of this heat shrink can identify the terminal number to use: Yellow would be terminal #4 Brown and Yellow would be #14, etc. [A] [B] [C] [D] [E] [F]

JST connector pins are a bit more sturdy than the Dupont pins. Not sure this extra mass is needed with 28AWG wire :wink: . The JSTs, however, are quite a bit more expensive. [G]

Great idea with the JST connectors, I'm glad my original question has inspired you :slight_smile: I would also like to present some of my solutions for connecting tiny wires to terminal blocks; This involves the use of crimp connectors; the type which are commonly used for automotive use. Specifically I am using blade connector's (DBN1.25-10) ( 5$ AUD for 200pcs on Aliexpress) and ring connectors (RV 1.25-4), as well as some good quality Irwin crimping pliers ( IRWIN VISE-GRIP Self-Adjusting Wire Stripper, 8",). I believe the tiny ribbon cable I am using is around 26 gauge, but 28 gauge should work fine too. First, I strip about 40mm of wire, twist it and then wrap it backwards over the insulation; [20220307_204856] However, if the connector hole is big enough, I found it was even better to bend a bit of the insulation backwards over itself, and then wrap the twisted wire around it, like you can see below. This also improved the quality of the crimp, and meant I only had to crimp it once. You can compare the quality to my original post here; How to connect tiny signal wires into screw terminal blocks? - #10 by GigaNerdTheReckoning I placed the connector inside before I wrapped the wire, which made it a lot easier to slide over the wire and insulation; [20220312_185845] [20220312_185252] Then crimped like so; [20220312_184557] [20220312_182450] These crimping methods are particularly useful for working with small gauge thermocouple wire, like we see below; [20220312_165422] [20220312_170431] This also proves useful for many high amp Solid State Relays, which use large ring connector terminals on the low current input side to the relay; [20220312_173904] Finally, here are the results for the blade connectors. Heat shrink is added for insulation and strain relief; [20220312_190342] [20220312_191726] You can also bend one of the blade's slightly, to allow for multiple wires into a single pole of the terminal, but LarryD's solution seems better suited to this, as it provides more clearance.

If you have a 3D printer make shrouds to convert stray dupont pins into a real connector. [1641538632289] [1646278178046] free download HERE Page also has mounts for lots of Arduino modules. [1643857014348] [1646281880196] [1646281146335] [1646280998333] [1646281074165]

Colour Code your Dupont Cabling When you make up Dupont cabling, match the colour of the wire to the source pin it connects to. Resistor colour code: 0 1 2 3 4 5 6 7 8 9 BK, BN, R, O, Y, GN, BE, V, SL, W At the destination, it is easy to identify the source pin number. When you come to pin 10 start again at Black . . .

SOT23 MOSFET 10k Pull Down on a SMD to SIP PCB Most of the time a ~10k pull down resistor is added from the Gate to the Source on MOSFETs. This resistor prevents a floating Gate situation. If you use SOT23 to SIP conversion PCBs, take advantage of the double-sided mounting of the board. On one side solder your SOT23 MOSFET, on the other side solder a 0805 - 10k resistor between pins 1 and 2. [A] [B] [C]

Convert THD Components to a SMD If you have a THD (Through Hole Device) you can easily convert it to the SMD form factor. As seen in the images below, a few basic hand tools are all that’s needed to do the job. The flattened leads can be bent away from or under the component in question.
