The solder wont stick.
You perhaps meaning PCB which means a printed circuit board. Solder is printed onto a specifically designed fiberglass board which electronic components can the be soldered onto (attached using liquid metal)
It is not all green colour, it depends on which kind of solder mask you need. PCB also has red, blue,white...
use wax with the solder n dont even use a soldering wire of large diameter.
There are resistors on the back of the PCB that come loose. New resistors and some solder should fix the problem. what is the PCB and its location.
Soldering will be required to install the universal oxygen sensors. Specifically you'll need to first cut the old sensor off on the main wiring. Then one needs to solder the universal sensor onto that existing wiring.
with a bread board you do not need to solder the components. you can just place them in the holes and remove them as you please.
To re-flow a BGA (Ball Grid Array) chip, first, remove the existing solder using a soldering iron or a hot air rework station. Then, apply solder paste to the pads on the PCB and position the BGA chip correctly. Use a reflow oven or a hot air tool to heat the assembly, allowing the solder to melt and form connections between the BGA balls and the PCB pads. Finally, let it cool down to solidify the solder joints.
Electroless Nickel Immersion Gold, a process used in printed circuit board manufacturing to give the PCB a cleaner solder contact.
i have the same problem, i open it, i find there are disconnected cable from the speaker to pcb, i solder it, problem solved
It's a toy that you can make at some schools. You get a PCB board and get three resistors and solder them to these holes in the PCB board and that how the electricity flows around the hole game.
I just want to solder this tin soldier back onto his tin horse. Let's solder our bowling team with a pizza night!
Manual soldering is too difficult because bridging have a more chance to happen thats why Step 1: Stencil printing method to paste that place with the help of stencil printer Step 2: Use pick and place machine to place the component of large qty otherwise manually put that component Step 3: Using Reflow machine to Solder that component
