The resistor should now be fastened on one side. Apply solder to the soldering tip again and touch the iron tip on the other side. Your resistor should now be good to go, but you might want to inspect the solder joints with your microscope or loupe to make sure the connection is good....
Soft soldering is a technique used to join wires, fix electronic components onto circuit boards and bond copper pipes together. This tutorial shows you how to solder step by step.
Solder, as a word, can be used in two different ways. Solder,the noun, refers to the alloy (a substance composed of two or more metals) that typically comes as a long, thin wire in spools or tubes. Solder,the verb, means to join together two pieces of metal in what is called as...
In electronics PCB Manufacturing, Assembly and Rework, the metals to be joined are the leads of the electronic components (thru-hole or SMD) with the copper tracks on the PCB. The alloy used to join these two metals is solder which is basically tin-lead (Sn-Pb) or tin-silver-copper (S...
Today, BGA soldering techniques is tried and tested and has been proved and trusted to be very reliable. It has also been learnt that once the process is set up correctly, BGA solder reliability is mush higher than that for quad flat packs (QFP) or any other SMD Package. ...
Next, I soldered two wires to the DC motor and connected the motor to the controller with the terminal block. As for the power, I connected two wires to the power terminal block, which on the other side have a DC power connector for connecting a 12V power supply. And that’s it, ou...
Step 2: Create and Use Solder Moldsstainless steel molds are created for each strip light design. They are holes that go on top of the bare PCB in order for the solder paste to be perfectly spread over the solder point.Step 3: Apply Lead-free Solder Paste Onto the Base PCBA number ...

If all is good, you can either solder the remaining LEDs/resistors in the circle in, or move on to the next section. Step 5: Transistor Switch The decade counter and 555 circuits are great for driving signals and one LED, but to drive multiple LEDs, you need a little help. This is ...
Remember the ESP8266 ALWAYS outputs a start up message on GPIO1, so for that short time GPIO1 is ALWAYS an output. So be sure to add a series 330R resistor between GPIO1 and whatever output is driving that input to prevent shorting things out during the startup message. ...
