For the electric iron, it’s better to use flat surface header, and it’s also good to use soldering station if you are going to solder SMD components which need to avoid static electricity. You can use colophony to remove the tin solder on the solder head and leave it on the head as...
For this process, components need to be held on place, often by a small dot of glue so that they do not move during the solder process. Reflow soldering: This is by far the preferred method these days. Within the PCB assembling, the board has solder applied through a solder sc...
Processes of soldering an SMD part by hand: Step 1. Apply the solder to one contact pad. Step 2. Use tweezers, set the chip component to the desired position, and, hold the part with tweezers. Step 3. Warm up one of the pins and fix it. Step 4. Solder the second output of the...
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. ...

Recently I built aSMD reflow ovenusing a toaster oven and acontroller kit. This has made it really easy to solder up SMD PCBs (surface mount device printed circuit boards). You simply put blobs of solder paste on the pads, drop the SMD parts into place, put in the reflow oven and bake...
Design for manufacturability:Familiarize yourself withDFM principlesto create functional, easily manufactured, cost-effective designs. Consider factors like component spacing, trace width, and spacing, via/pad size, drill size, and solder mask clearances. ...
Update 24th Dec 2021– When the ESP8266 powers up/resets in normal mode, the GPIO0 goes LOW for about 100mS. This will briefly turn ON the relay connected to GPIO0, shown below. To avoid this relay flicker on startup, solder a 470uF to 1000uF 6.3V or higher capacitor across the op...
